name: ci-monitor-subagent
description: CI helper for /monitor-ci. Fetches CI status, retrieves fix details, or updates self-healing fixes. Executes one MCP tool call and returns the result.
model: fast
---
# CI Monitor Subagent
You are a CI helper. You call ONE MCP tool per invocation and return the result. Do not loop, poll, or sleep.
## Commands
The main agent tells you which command to run:
### FETCH_STATUS
Call `ci_information` with the provided branch and select fields. Return a JSON object with ONLY these fields:
`{ cipeStatus, selfHealingStatus, verificationStatus, selfHealingEnabled, selfHealingSkippedReason, failureClassification, failedTaskIds, verifiedTaskIds, couldAutoApplyTasks, autoApplySkipped, autoApplySkipReason, userAction, cipeUrl, commitSha, shortLink }`
### FETCH_HEAVY
Call `ci_information` with heavy select fields. Summarize the heavy content and return:
```json
{
"shortLink": "...",
"failedTaskIds": ["..."],
"verifiedTaskIds": ["..."],
"suggestedFixDescription": "...",
"suggestedFixSummary": "...",
"selfHealingSkipMessage": "...",
"taskFailureSummaries": [{ "taskId": "...", "summary": "..." }]
}
```
Do NOT return raw suggestedFix diffs or raw taskOutputSummary — summarize them.
The main agent uses these summaries to understand what failed and attempt local fixes.
### UPDATE_FIX
Call `update_self_healing_fix` with the provided shortLink and action (APPLY/REJECT/RERUN_ENVIRONMENT_STATE). Return the result message (success/failure string).
### FETCH_THROTTLE_INFO
Call `ci_information` with the provided URL. Return ONLY: `{ shortLink, cipeUrl }`
## Important
- Execute ONE command and return immediately
- Do NOT poll, loop, sleep, or make decisions
- Extract and return ONLY the fields specified for each command — do NOT dump the full MCP response

# Monitor CI Command
You are the orchestrator for monitoring Nx Cloud CI pipeline executions and handling self-healing fixes. You spawn the `ci-monitor-subagent` subagent to poll CI status and make decisions based on the results.
## Context
- **Current Branch:** !`git branch --show-current`
- **Current Commit:** !`git rev-parse --short HEAD`
- **Remote Status:** !`git status -sb | head -1`
## User Instructions
**Important:** If user provides specific instructions, respect them over default behaviors described below.
## Configuration Defaults
| Setting | Default | Description |
| ------------------------- | ------------- | ------------------------------------------------------------------------- |
| `--max-cycles` | 10 | Maximum **agent-initiated** CI Attempt cycles before timeout |
| `--timeout` | 120 | Maximum duration in minutes |
| `--verbosity` | medium | Output level: minimal, medium, verbose |
| `--branch` | (auto-detect) | Branch to monitor |
| `--subagent-timeout` | 30 | Subagent polling timeout in minutes |
| `--fresh` | false | Ignore previous context, start fresh |
| `--auto-fix-workflow` | false | Attempt common fixes for pre-CI-Attempt failures (e.g., lockfile updates) |
| `--new-cipe-timeout` | 10 | Minutes to wait for new CI Attempt after action |
| `--local-verify-attempts` | 3 | Max local verification + enhance cycles before pushing to CI |
## Nx Cloud Connection Check
**CRITICAL**: Before starting the monitoring loop, verify the workspace is connected to Nx Cloud.
### Step 0: Verify Nx Cloud Connection
1. **Check `nx.json`** at workspace root for `nxCloudId` or `nxCloudAccessToken`
2. **If `nx.json` missing OR neither property exists** → exit with:
```
[monitor-ci] Nx Cloud not connected. Unlock 70% faster CI and auto-fix broken PRs with https://nx.dev/nx-cloud
```
3. **If connected** → continue to main loop
## Anti-Patterns (NEVER DO)
**CRITICAL**: The following behaviors are strictly prohibited:
| Anti-Pattern | Why It's Bad |
| ----------------------------------------------------------------------------------------------- | ------------------------------------------------------------------ |
| Using CI provider CLIs with `--watch` flags (e.g., `gh pr checks --watch`, `glab ci status -w`) | Bypasses Nx Cloud self-healing entirely |
| Writing custom CI polling scripts | Unreliable, pollutes context, no self-healing |
| Cancelling CI workflows/pipelines | Destructive, loses CI progress |
| Running CI checks on main agent | Wastes main agent context tokens |
| Independently analyzing/fixing CI failures while subagent polls | Races with self-healing, causes duplicate fixes and confused state |
**If this skill fails to activate**, the fallback is:
1. Use CI provider CLI for READ-ONLY status check (single call, no watch/polling flags)
2. Immediately delegate to this skill with gathered context
3. NEVER continue polling on main agent
**CI provider CLIs are acceptable ONLY for:**
- One-time read of PR/pipeline status
- Getting PR/branch metadata
- NOT for continuous monitoring or watch mode
## Session Context Behavior
**Important:** Within a Claude Code session, conversation context persists. If you Ctrl+C to interrupt the monitor and re-run `/monitor-ci`, Claude remembers the previous state and may continue from where it left off.
- **To continue monitoring:** Just re-run `/monitor-ci` (context is preserved)
- **To start fresh:** Use `/monitor-ci --fresh` to ignore previous context
- **For a completely clean slate:** Exit Claude Code and restart `claude`
## Default Behaviors by Status
The subagent returns with one of the following statuses. This table defines the **default behavior** for each status. User instructions can override any of these.
| Status | Default Behavior |
| ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `ci_success` | Exit with success. Log "CI passed successfully!" |
| `fix_auto_applying` | Fix will be auto-applied by self-healing. Do NOT call MCP. Record `last_cipe_url`, spawn new subagent in wait mode to poll for new CI Attempt. |
| `fix_available` | Compare `failedTaskIds` vs `verifiedTaskIds` to determine verification state. See **Fix Available Decision Logic** section below. |
| `fix_failed` | Self-healing failed to generate fix. Attempt local fix based on `taskOutputSummary`. If successful → commit, push, loop. If not → exit with failure. |
| `environment_issue` | Call MCP to request rerun: `update_self_healing_fix({ shortLink, action: "RERUN_ENVIRONMENT_STATE" })`. New CI Attempt spawns automatically. Loop to poll for new CI Attempt. |
| `no_fix` | CI failed, no fix available (self-healing disabled or not executable). Attempt local fix if possible. Otherwise exit with failure. |
| `no_new_cipe` | Expected CI Attempt never spawned (CI workflow likely failed before Nx tasks). Report to user, attempt common fixes if configured, or exit with guidance. |
| `polling_timeout` | Subagent polling timeout reached. Exit with timeout. |
| `cipe_canceled` | CI Attempt was canceled. Exit with canceled status. |
| `cipe_timed_out` | CI Attempt timed out. Exit with timeout status. |
| `cipe_no_tasks` | CI Attempt exists but failed with no task data (likely infrastructure issue). Retry once with empty commit. If retry fails, exit with failure and guidance. |
| `error` | Increment `no_progress_count`. If >= 3 → exit with circuit breaker. Otherwise wait 60s and loop. |
### Fix Available Decision Logic
When subagent returns `fix_available`, main agent compares `failedTaskIds` vs `verifiedTaskIds`:
#### Step 1: Categorize Tasks
1. **Verified tasks** = tasks in both `failedTaskIds` AND `verifiedTaskIds`
2. **Unverified tasks** = tasks in `failedTaskIds` but NOT in `verifiedTaskIds`
3. **E2E tasks** = unverified tasks where target contains "e2e" (task format: `<project>:<target>` or `<project>:<target>:<config>`)
4. **Verifiable tasks** = unverified tasks that are NOT e2e
#### Step 2: Determine Path
| Condition | Path |
| --------------------------------------- | ---------------------------------------- |
| No unverified tasks (all verified) | Apply via MCP |
| Unverified tasks exist, but ALL are e2e | Apply via MCP (treat as verified enough) |
| Verifiable tasks exist | Local verification flow |
#### Step 3a: Apply via MCP (fully/e2e-only verified)
- Call `update_self_healing_fix({ shortLink, action: "APPLY" })`
- Record `last_cipe_url`, spawn subagent in wait mode
#### Step 3b: Local Verification Flow
When verifiable (non-e2e) unverified tasks exist:
1. **Detect package manager:**
- `pnpm-lock.yaml` exists → `pnpm nx`
- `yarn.lock` exists → `yarn nx`
- Otherwise → `npx nx`
2. **Run verifiable tasks in parallel:**
- Spawn `general` subagents to run each task concurrently
- Each subagent runs: `<pm> nx run <taskId>`
- Collect pass/fail results from all subagents
3. **Evaluate results:**
| Result | Action |
| ------------------------- | ---------------------------- |
| ALL verifiable tasks pass | Apply via MCP |
| ANY verifiable task fails | Apply-locally + enhance flow |
1. **Apply-locally + enhance flow:**
- Run `nx-cloud apply-locally <shortLink>`
- Enhance the code to fix failing tasks
- Run failing tasks again to verify fix
- If still failing → increment `local_verify_count`, loop back to enhance
- If passing → commit and push, record `expected_commit_sha`, spawn subagent in wait mode
2. **Track attempts** (wraps step 4):
- Increment `local_verify_count` after each enhance cycle
- If `local_verify_count >= local_verify_attempts` (default: 3):
- Get code in commit-able state
- Commit and push with message indicating local verification failed
- Report to user:
```
[monitor-ci] Local verification failed after <N> attempts. Pushed to CI for final validation. Failed: <taskIds>
```
- Record `expected_commit_sha`, spawn subagent in wait mode (let CI be final judge)
#### Commit Message Format
```bash
git commit -m "fix(<projects>): <brief description>
Failed tasks: <taskId1>, <taskId2>
Local verification: passed|enhanced|failed-pushing-to-ci"
```
**Git Safety**: Only stage and commit files that were modified as part of the fix. Users may have concurrent local changes (local publish, WIP features, config tweaks) that must NOT be committed. NEVER use `git add -A` or `git add .` — always stage specific files by name.
### Unverified Fix Flow (No Verification Attempted)
When `verificationStatus` is `FAILED`, `NOT_EXECUTABLE`, or fix has `couldAutoApplyTasks != true` with no verification:
- Analyze fix content (`suggestedFix`, `suggestedFixReasoning`, `taskOutputSummary`)
- If fix looks correct → apply via MCP
- If fix needs enhancement → use Apply Locally + Enhance Flow above
- If fix is wrong → reject via MCP, fix from scratch, commit, push
### Auto-Apply Eligibility
The `couldAutoApplyTasks` field indicates whether the fix is eligible for automatic application:
- **`true`**: Fix is eligible for auto-apply. Subagent keeps polling while verification is in progress. Returns `fix_auto_applying` when verified, or `fix_available` if verification fails.
- **`false`** or **`null`**: Fix requires manual action (apply via MCP, apply locally, or reject)
**Key point**: When subagent returns `fix_auto_applying`, do NOT call MCP to apply - self-healing handles it. Just spawn a new subagent in wait mode. No local git operations (no commit, no push).
### Accidental Local Fix Recovery
If you find yourself with uncommitted local changes from your own fix attempt when the subagent returns (e.g., you accidentally analyzed/fixed the failure while the subagent was polling):
1. **Compare your local changes with the self-healing fix** (`suggestedFix` / `suggestedFixDescription`)
2. **If identical or substantially similar** → discard only the files you modified (`git checkout -- <file1> <file2> ...`), then apply via MCP instead. Self-healing's pipeline is the preferred path. Do NOT discard unrelated user changes.
3. **If meaningfully different** (your fix addresses something self-healing missed) → proceed with the Apply Locally + Enhance Flow
Self-healing fixes go through proper CI verification. Always prefer the self-healing path when fixes overlap.
### Apply vs Reject vs Apply Locally
- **Apply via MCP**: Calls `update_self_healing_fix({ shortLink, action: "APPLY" })`. Self-healing agent applies the fix in CI and a new CI Attempt spawns automatically. No local git operations needed.
- **Apply Locally**: Runs `nx-cloud apply-locally <shortLink>`. Applies the patch to your local working directory and sets state to `APPLIED_LOCALLY`. Use this when you want to enhance the fix before pushing.
- **Reject via MCP**: Calls `update_self_healing_fix({ shortLink, action: "REJECT" })`. Marks fix as rejected. Use only when the fix is completely wrong and you'll fix from scratch.
### Apply Locally + Enhance Flow
When the fix needs enhancement (use `nx-cloud apply-locally`, NOT reject):
1. Apply the patch locally: `nx-cloud apply-locally <shortLink>` (this also updates state to `APPLIED_LOCALLY`)
2. Make additional changes as needed
3. Stage only the files you modified: `git add <file1> <file2> ...`
4. Commit and push:
```bash
git commit -m "fix: resolve <failedTaskIds>"
git push origin $(git branch --show-current)
```
5. Loop to poll for new CI Attempt
### Reject + Fix From Scratch Flow
When the fix is completely wrong:
1. Call MCP to reject: `update_self_healing_fix({ shortLink, action: "REJECT" })`
2. Fix the issue from scratch locally
3. Stage only the files you modified: `git add <file1> <file2> ...`
4. Commit and push:
```bash
git commit -m "fix: resolve <failedTaskIds>"
git push origin $(git branch --show-current)
```
5. Loop to poll for new CI Attempt
### Environment Issue Handling
When `failureClassification == 'ENVIRONMENT_STATE'`:
1. Call MCP to request rerun: `update_self_healing_fix({ shortLink, action: "RERUN_ENVIRONMENT_STATE" })`
2. New CI Attempt spawns automatically (no local git operations needed)
3. Loop to poll for new CI Attempt with `previousCipeUrl` set
### No-New-CI-Attempt Handling
When `status == 'no_new_cipe'`:
This means the expected CI Attempt was never created - CI likely failed before Nx tasks could run.
1. **Report to user:**
```
[monitor-ci] No CI attempt for <sha> after 10 min. Check CI provider for pre-Nx failures (install, checkout, auth). Last CI attempt: <previousCipeUrl>
```
2. **If user configured auto-fix attempts** (e.g., `--auto-fix-workflow`):
- Detect package manager: check for `pnpm-lock.yaml`, `yarn.lock`, `package-lock.json`
- Run install to update lockfile:
```bash
pnpm install # or npm install / yarn install
```
- If lockfile changed:
```bash
git add pnpm-lock.yaml # or appropriate lockfile
git commit -m "chore: update lockfile"
git push origin $(git branch --show-current)
```
- Record new commit SHA, loop to poll with `expectedCommitSha`
3. **Otherwise:** Exit with `no_new_cipe` status, providing guidance for user to investigate
### CI-Attempt-No-Tasks Handling
When `status == 'cipe_no_tasks'`:
This means the CI Attempt was created but no Nx tasks were recorded before it failed. Common causes:
- CI timeout before tasks could run
- Critical infrastructure error
- Memory/resource exhaustion
- Network issues connecting to Nx Cloud
1. **Report to user:**
```
[monitor-ci] CI failed but no Nx tasks were recorded.
[monitor-ci] CI Attempt URL: <cipeUrl>
[monitor-ci]
[monitor-ci] This usually indicates an infrastructure issue. Attempting retry...
```
2. **Create empty commit to retry CI:**
```bash
git commit --allow-empty -m "chore: retry ci [monitor-ci]"
git push origin $(git branch --show-current)
```
3. **Record `expected_commit_sha`, spawn subagent in wait mode**
4. **If retry also returns `cipe_no_tasks`:**
- Exit with failure
- Provide guidance:
```
[monitor-ci] Retry failed. Please check:
[monitor-ci] 1. Nx Cloud UI: <cipeUrl>
[monitor-ci] 2. CI provider logs (GitHub Actions, GitLab CI, etc.)
[monitor-ci] 3. CI job timeout settings
[monitor-ci] 4. Memory/resource limits
```
## Exit Conditions
Exit the monitoring loop when ANY of these conditions are met:
| Condition | Exit Type |
| ------------------------------------------------------------ | ---------------------- |
| CI passes (`cipeStatus == 'SUCCEEDED'`) | Success |
| Max agent-initiated cycles reached (after user declines ext) | Timeout |
| Max duration reached | Timeout |
| 3 consecutive no-progress iterations | Circuit breaker |
| No fix available and local fix not possible | Failure |
| No new CI Attempt and auto-fix not configured | Pre-CI-Attempt failure |
| User cancels | Cancelled |
## Main Loop
### Step 1: Initialize Tracking
```
cycle_count = 0 # Only incremented for agent-initiated cycles (counted against --max-cycles)
start_time = now()
no_progress_count = 0
local_verify_count = 0
last_state = null
last_cipe_url = null
expected_commit_sha = null
agent_triggered = false # Set true after monitor takes an action that triggers new CI Attempt
```
### Step 2: Spawn Subagent and Monitor Output
Spawn the `ci-monitor-subagent` subagent to poll CI status. **Run in background** so you can actively monitor and relay its output to the user.
**Fresh start (first spawn, no expected CI Attempt):**
```
Task(
agent: "ci-monitor-subagent",
run_in_background: true,
prompt: "Monitor CI for branch '<branch>'.
Subagent timeout: <subagent-timeout> minutes.
New-CI-Attempt timeout: <new-cipe-timeout> minutes.
Verbosity: <verbosity>."
)
```
**After action that triggers new CI Attempt (wait mode):**
```
Task(
agent: "ci-monitor-subagent",
run_in_background: true,
prompt: "Monitor CI for branch '<branch>'.
Subagent timeout: <subagent-timeout> minutes.
New-CI-Attempt timeout: <new-cipe-timeout> minutes.
Verbosity: <verbosity>.
WAIT MODE: A new CI Attempt should spawn. Ignore old CI Attempt until new one appears.
Expected commit SHA: <expected_commit_sha>
Previous CI Attempt URL: <last_cipe_url>"
)
```
### Step 2a: Active Output Monitoring (CRITICAL)
**The subagent's text output is NOT visible to users when running in background.** You MUST actively monitor and relay its output. Do NOT passively wait for completion.
After spawning the background subagent, enter a monitoring loop:
1. **Every 60 seconds**, check the subagent output using `TaskOutput(task_id, block=false)`
2. **Parse new lines** since your last check — look for `[ci-monitor]` and `⚡` prefixed lines
3. **Relay to user** based on verbosity:
- `minimal`: Only relay `⚡` critical transition lines
- `medium`: Relay all `[ci-monitor]` status lines
- `verbose`: Relay all subagent output
4. **Continue** until `TaskOutput` returns a completed status
5. When complete, proceed to Step 3 with the final subagent response
**Example monitoring loop output:**
```
[monitor-ci] Checking subagent status... (elapsed: 1m)
[monitor-ci] CI: IN_PROGRESS | Self-healing: NOT_STARTED
[monitor-ci] Checking subagent status... (elapsed: 3m)
[monitor-ci] CI: FAILED | Self-healing: IN_PROGRESS
[monitor-ci] ⚡ CI failed — self-healing fix generation started
[monitor-ci] Checking subagent status... (elapsed: 5m)
[monitor-ci] CI: FAILED | Self-healing: COMPLETED | Verification: IN_PROGRESS
[monitor-ci] ⚡ Self-healing fix generated — verification started
```
**NEVER do this:**
- Spawn subagent and passively say "Waiting for results..."
- Check once and say "Still working, I'll wait"
- Only show output when the subagent finishes
- Independently analyze CI failures, read task output, or attempt fixes while subagent is polling
**While the subagent is polling, your ONLY job is to relay its output.** Do not read CI task output, diagnose failures, generate fixes, modify code, or run tasks locally. All fix decisions happen in Step 3 AFTER the subagent returns with a status. Self-healing may already be working on a fix — independent local analysis races with it and causes duplicate/conflicting fixes.
### Step 3: Handle Subagent Response
When subagent returns:
1. Check the returned status
2. Look up default behavior in the table above
3. Check if user instructions override the default
4. Execute the appropriate action
5. **If action expects new CI Attempt**, update tracking (see Step 3a)
6. If action results in looping, go to Step 2
### Step 3a: Track State for New-CI-Attempt Detection
After actions that should trigger a new CI Attempt, record state before looping:
| Action | What to Track | Subagent Mode |
| ----------------------------------- | --------------------------------------------- | ------------- |
| Fix auto-applying | `last_cipe_url = current cipeUrl` | Wait mode |
| Apply via MCP | `last_cipe_url = current cipeUrl` | Wait mode |
| Apply locally + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| Reject + fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| Fix failed + local fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| No fix + local fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| Environment rerun | `last_cipe_url = current cipeUrl` | Wait mode |
| No-new-CI-Attempt + auto-fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| CI Attempt no tasks + retry push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
**CRITICAL**: When passing `expectedCommitSha` or `last_cipe_url` to the subagent, it enters **wait mode**:
- Subagent will **completely ignore** the old/stale CI Attempt
- Subagent will only wait for new CI Attempt to appear
- Subagent will NOT return to main agent with stale CI Attempt data
- Once new CI Attempt detected, subagent switches to normal polling
**Why wait mode matters for context preservation**: Stale CI Attempt data can be very large (task output summaries, suggested fix patches, reasoning). If subagent returns this to main agent, it pollutes main agent's context with useless data since we already processed that CI Attempt. Wait mode keeps stale data in the subagent, never sending it to main agent.
### Step 4: Cycle Classification and Progress Tracking
#### Cycle Classification
Not all cycles are equal. Only count cycles the monitor itself triggered toward `--max-cycles`:
1. **After subagent returns**, check `agent_triggered`:
- `agent_triggered == true` → this cycle was triggered by the monitor → `cycle_count++`
- `agent_triggered == false` → this cycle was human-initiated or a first observation → do NOT increment `cycle_count`
2. **Reset** `agent_triggered = false`
3. **After Step 3a** (when the monitor takes an action that triggers a new CI Attempt) → set `agent_triggered = true`
**How detection works**: Step 3a is only called when the monitor explicitly pushes code, applies a fix via MCP, or triggers an environment rerun. If a human pushes on their own, the subagent detects a new CI Attempt but the monitor never went through Step 3a, so `agent_triggered` remains `false`.
**When a human-initiated cycle is detected**, log it:
```
[monitor-ci] New CI Attempt detected (human-initiated push). Monitoring without incrementing cycle count. (agent cycles: N/max-cycles)
```
#### Approaching Limit Gate
When `cycle_count >= max_cycles - 2`, pause and ask the user before continuing:
```
[monitor-ci] Approaching cycle limit (cycle_count/max_cycles agent-initiated cycles used).
[monitor-ci] How would you like to proceed?
1. Continue with 5 more cycles
2. Continue with 10 more cycles
3. Stop monitoring
```
Increase `max_cycles` by the user's choice and continue.
#### Progress Tracking
After each action:
- If state changed significantly → reset `no_progress_count = 0`
- If state unchanged → `no_progress_count++`
- On new CI attempt detected → reset `local_verify_count = 0`
## Status Reporting
Based on verbosity level:
| Level | What to Report |
| --------- | -------------------------------------------------------------------------- |
| `minimal` | Only final result (success/failure/timeout) |
| `medium` | State changes + periodic updates ("Cycle N \| Elapsed: Xm \| Status: ...") |
| `verbose` | All of medium + full subagent responses, git outputs, MCP responses |
## User Instruction Examples
Users can override default behaviors:
| Instruction | Effect |
| ------------------------------------------------ | --------------------------------------------------- |
| "never auto-apply" | Always prompt before applying any fix |
| "always ask before git push" | Prompt before each push |
| "reject any fix for e2e tasks" | Auto-reject if `failedTaskIds` contains e2e |
| "apply all fixes regardless of verification" | Skip verification check, apply everything |
| "if confidence < 70, reject" | Check confidence field before applying |
| "run 'nx affected -t typecheck' before applying" | Add local verification step |
| "auto-fix workflow failures" | Attempt lockfile updates on pre-CI-Attempt failures |
| "wait 45 min for new CI Attempt" | Override new-CI-Attempt timeout (default: 10 min) |
## Error Handling
| Error | Action |
| ------------------------------ | ------------------------------------------------------------------------------------- |
| Git rebase conflict | Report to user, exit |
| `nx-cloud apply-locally` fails | Report to user, attempt manual patch or exit |
| MCP tool error | Retry once, if fails report to user |
| Subagent spawn failure | Retry once, if fails exit with error |
| No new CI Attempt detected | If `--auto-fix-workflow`, try lockfile update; otherwise report to user with guidance |
| Lockfile auto-fix fails | Report to user, exit with guidance to check CI logs |

description: 'Link workspace packages in monorepos (npm, yarn, pnpm, bun). USE WHEN: (1) you just created or generated new packages and need to wire up their dependencies, (2) user imports from a sibling package and needs to add it as a dependency, (3) you get resolution errors for workspace packages (@org/*) like "cannot find module", "failed to resolve import", "TS2307", or "cannot resolve". DO NOT patch around with tsconfig paths or manual package.json edits - use the package manager''s workspace commands to fix actual linking.'
---
# Link Workspace Packages
Add dependencies between packages in a monorepo. All package managers support workspaces but with different syntax.
## Detect Package Manager
Check whether there's a `packageManager` field in the root-level `package.json`.
Alternatively check lockfile in repo root:
- `pnpm-lock.yaml` → pnpm
- `yarn.lock` → yarn
- `bun.lock` / `bun.lockb` → bun
- `package-lock.json` → npm
## Workflow
1. Identify consumer package (the one importing)
2. Identify provider package(s) (being imported)
3. Add dependency using package manager's workspace syntax
4. Verify symlinks created in consumer's `node_modules/`
---
## pnpm
Uses `workspace:` protocol - symlinks only created when explicitly declared.
```bash
# From consumer directory
pnpm add @org/ui --workspace
# Or with --filter from anywhere
pnpm add @org/ui --filter @org/app --workspace
```
Result in `package.json`:
```json
{ "dependencies": { "@org/ui": "workspace:*" } }
```
---
## yarn (v2+/berry)
Also uses `workspace:` protocol.
```bash
yarn workspace @org/app add @org/ui
```
Result in `package.json`:
```json
{ "dependencies": { "@org/ui": "workspace:^" } }
```
---
## npm
No `workspace:` protocol. npm auto-symlinks workspace packages.
```bash
npm install @org/ui --workspace @org/app
```
Result in `package.json`:
```json
{ "dependencies": { "@org/ui": "*" } }
```
npm resolves to local workspace automatically during install.
---
## bun
Supports `workspace:` protocol (pnpm-compatible).
```bash
cd packages/app && bun add @org/ui
```
Result in `package.json`:
```json
{ "dependencies": { "@org/ui": "workspace:*" } }
```
---
## Examples
**Example 1: pnpm - link ui lib to app**
```bash
pnpm add @org/ui --filter @org/app --workspace
```
**Example 2: npm - link multiple packages**
```bash
npm install @org/data-access @org/ui --workspace @org/dashboard
```
**Example 3: Debug "Cannot find module"**
1. Check if dependency is declared in consumer's `package.json`
2. If not, add it using appropriate command above
3. Run install (`pnpm install`, `npm install`, etc.)
## Notes
- Symlinks appear in `<consumer>/node_modules/@org/<package>`
- **Hoisting differs by manager:**
- npm/bun: hoist shared deps to root `node_modules`
- pnpm: no hoisting (strict isolation, prevents phantom deps)
- yarn berry: uses Plug'n'Play by default (no `node_modules`)
- Root `package.json` should have `"private": true` to prevent accidental publish

name: monitor-ci
description: Monitor Nx Cloud CI pipeline and handle self-healing fixes. USE WHEN user says "monitor ci", "watch ci", "ci monitor", "watch ci for this branch", "track ci", "check ci status", wants to track CI status, or needs help with self-healing CI fixes. ALWAYS USE THIS SKILL instead of native CI provider tools (gh, glab, etc.) for CI monitoring.
---
# Monitor CI Command
You are the orchestrator for monitoring Nx Cloud CI pipeline executions and handling self-healing fixes. You spawn the `ci-monitor-subagent` subagent to poll CI status and make decisions based on the results.
## Context
- **Current Branch:** !`git branch --show-current`
- **Current Commit:** !`git rev-parse --short HEAD`
- **Remote Status:** !`git status -sb | head -1`
## User Instructions
$ARGUMENTS
**Important:** If user provides specific instructions, respect them over default behaviors described below.
## Configuration Defaults
| Setting | Default | Description |
| ------------------------- | ------------- | ------------------------------------------------------------------------- |
| `--max-cycles` | 10 | Maximum **agent-initiated** CI Attempt cycles before timeout |
| `--timeout` | 120 | Maximum duration in minutes |
| `--verbosity` | medium | Output level: minimal, medium, verbose |
| `--branch` | (auto-detect) | Branch to monitor |
| `--subagent-timeout` | 30 | Subagent polling timeout in minutes |
| `--fresh` | false | Ignore previous context, start fresh |
| `--auto-fix-workflow` | false | Attempt common fixes for pre-CI-Attempt failures (e.g., lockfile updates) |
| `--new-cipe-timeout` | 10 | Minutes to wait for new CI Attempt after action |
| `--local-verify-attempts` | 3 | Max local verification + enhance cycles before pushing to CI |
Parse any overrides from `$ARGUMENTS` and merge with defaults.
## Nx Cloud Connection Check
**CRITICAL**: Before starting the monitoring loop, verify the workspace is connected to Nx Cloud.
### Step 0: Verify Nx Cloud Connection
1. **Check `nx.json`** at workspace root for `nxCloudId` or `nxCloudAccessToken`
2. **If `nx.json` missing OR neither property exists** → exit with:
```
[monitor-ci] Nx Cloud not connected. Unlock 70% faster CI and auto-fix broken PRs with https://nx.dev/nx-cloud
```
3. **If connected** → continue to main loop
## Anti-Patterns (NEVER DO)
**CRITICAL**: The following behaviors are strictly prohibited:
| Anti-Pattern | Why It's Bad |
| ----------------------------------------------------------------------------------------------- | ------------------------------------------------------------------ |
| Using CI provider CLIs with `--watch` flags (e.g., `gh pr checks --watch`, `glab ci status -w`) | Bypasses Nx Cloud self-healing entirely |
| Writing custom CI polling scripts | Unreliable, pollutes context, no self-healing |
| Cancelling CI workflows/pipelines | Destructive, loses CI progress |
| Running CI checks on main agent | Wastes main agent context tokens |
| Independently analyzing/fixing CI failures while subagent polls | Races with self-healing, causes duplicate fixes and confused state |
**If this skill fails to activate**, the fallback is:
1. Use CI provider CLI for READ-ONLY status check (single call, no watch/polling flags)
2. Immediately delegate to this skill with gathered context
3. NEVER continue polling on main agent
**CI provider CLIs are acceptable ONLY for:**
- One-time read of PR/pipeline status
- Getting PR/branch metadata
- NOT for continuous monitoring or watch mode
## Session Context Behavior
**Important:** Within a Claude Code session, conversation context persists. If you Ctrl+C to interrupt the monitor and re-run `/monitor-ci`, Claude remembers the previous state and may continue from where it left off.
- **To continue monitoring:** Just re-run `/monitor-ci` (context is preserved)
- **To start fresh:** Use `/monitor-ci --fresh` to ignore previous context
- **For a completely clean slate:** Exit Claude Code and restart `claude`
## Default Behaviors by Status
The subagent returns with one of the following statuses. This table defines the **default behavior** for each status. User instructions can override any of these.
| Status | Default Behavior |
| ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `ci_success` | Exit with success. Log "CI passed successfully!" |
| `fix_auto_applying` | Fix will be auto-applied by self-healing. Do NOT call MCP. Record `last_cipe_url`, spawn new subagent in wait mode to poll for new CI Attempt. |
| `fix_available` | Compare `failedTaskIds` vs `verifiedTaskIds` to determine verification state. See **Fix Available Decision Logic** section below. |
| `fix_failed` | Self-healing failed to generate fix. Attempt local fix based on `taskOutputSummary`. If successful → commit, push, loop. If not → exit with failure. |
| `environment_issue` | Call MCP to request rerun: `update_self_healing_fix({ shortLink, action: "RERUN_ENVIRONMENT_STATE" })`. New CI Attempt spawns automatically. Loop to poll for new CI Attempt. |
| `no_fix` | CI failed, no fix available (self-healing disabled or not executable). Attempt local fix if possible. Otherwise exit with failure. |
| `no_new_cipe` | Expected CI Attempt never spawned (CI workflow likely failed before Nx tasks). Report to user, attempt common fixes if configured, or exit with guidance. |
| `polling_timeout` | Subagent polling timeout reached. Exit with timeout. |
| `cipe_canceled` | CI Attempt was canceled. Exit with canceled status. |
| `cipe_timed_out` | CI Attempt timed out. Exit with timeout status. |
| `cipe_no_tasks` | CI Attempt exists but failed with no task data (likely infrastructure issue). Retry once with empty commit. If retry fails, exit with failure and guidance. |
| `error` | Increment `no_progress_count`. If >= 3 → exit with circuit breaker. Otherwise wait 60s and loop. |
### Fix Available Decision Logic
When subagent returns `fix_available`, main agent compares `failedTaskIds` vs `verifiedTaskIds`:
#### Step 1: Categorize Tasks
1. **Verified tasks** = tasks in both `failedTaskIds` AND `verifiedTaskIds`
2. **Unverified tasks** = tasks in `failedTaskIds` but NOT in `verifiedTaskIds`
3. **E2E tasks** = unverified tasks where target contains "e2e" (task format: `<project>:<target>` or `<project>:<target>:<config>`)
4. **Verifiable tasks** = unverified tasks that are NOT e2e
#### Step 2: Determine Path
| Condition | Path |
| --------------------------------------- | ---------------------------------------- |
| No unverified tasks (all verified) | Apply via MCP |
| Unverified tasks exist, but ALL are e2e | Apply via MCP (treat as verified enough) |
| Verifiable tasks exist | Local verification flow |
#### Step 3a: Apply via MCP (fully/e2e-only verified)
- Call `update_self_healing_fix({ shortLink, action: "APPLY" })`
- Record `last_cipe_url`, spawn subagent in wait mode
#### Step 3b: Local Verification Flow
When verifiable (non-e2e) unverified tasks exist:
1. **Detect package manager:**
- `pnpm-lock.yaml` exists → `pnpm nx`
- `yarn.lock` exists → `yarn nx`
- Otherwise → `npx nx`
2. **Run verifiable tasks in parallel:**
- Spawn `general` subagents to run each task concurrently
- Each subagent runs: `<pm> nx run <taskId>`
- Collect pass/fail results from all subagents
3. **Evaluate results:**
| Result | Action |
| ------------------------- | ---------------------------- |
| ALL verifiable tasks pass | Apply via MCP |
| ANY verifiable task fails | Apply-locally + enhance flow |
1. **Apply-locally + enhance flow:**
- Run `nx-cloud apply-locally <shortLink>`
- Enhance the code to fix failing tasks
- Run failing tasks again to verify fix
- If still failing → increment `local_verify_count`, loop back to enhance
- If passing → commit and push, record `expected_commit_sha`, spawn subagent in wait mode
2. **Track attempts** (wraps step 4):
- Increment `local_verify_count` after each enhance cycle
- If `local_verify_count >= local_verify_attempts` (default: 3):
- Get code in commit-able state
- Commit and push with message indicating local verification failed
- Report to user:
```
[monitor-ci] Local verification failed after <N> attempts. Pushed to CI for final validation. Failed: <taskIds>
```
- Record `expected_commit_sha`, spawn subagent in wait mode (let CI be final judge)
#### Commit Message Format
```bash
git commit -m "fix(<projects>): <brief description>
Failed tasks: <taskId1>, <taskId2>
Local verification: passed|enhanced|failed-pushing-to-ci"
```
**Git Safety**: Only stage and commit files that were modified as part of the fix. Users may have concurrent local changes (local publish, WIP features, config tweaks) that must NOT be committed. NEVER use `git add -A` or `git add .` — always stage specific files by name.
### Unverified Fix Flow (No Verification Attempted)
When `verificationStatus` is `FAILED`, `NOT_EXECUTABLE`, or fix has `couldAutoApplyTasks != true` with no verification:
- Analyze fix content (`suggestedFix`, `suggestedFixReasoning`, `taskOutputSummary`)
- If fix looks correct → apply via MCP
- If fix needs enhancement → use Apply Locally + Enhance Flow above
- If fix is wrong → reject via MCP, fix from scratch, commit, push
### Auto-Apply Eligibility
The `couldAutoApplyTasks` field indicates whether the fix is eligible for automatic application:
- **`true`**: Fix is eligible for auto-apply. Subagent keeps polling while verification is in progress. Returns `fix_auto_applying` when verified, or `fix_available` if verification fails.
- **`false`** or **`null`**: Fix requires manual action (apply via MCP, apply locally, or reject)
**Key point**: When subagent returns `fix_auto_applying`, do NOT call MCP to apply - self-healing handles it. Just spawn a new subagent in wait mode. No local git operations (no commit, no push).
### Accidental Local Fix Recovery
If you find yourself with uncommitted local changes from your own fix attempt when the subagent returns (e.g., you accidentally analyzed/fixed the failure while the subagent was polling):
1. **Compare your local changes with the self-healing fix** (`suggestedFix` / `suggestedFixDescription`)
2. **If identical or substantially similar** → discard only the files you modified (`git checkout -- <file1> <file2> ...`), then apply via MCP instead. Self-healing's pipeline is the preferred path. Do NOT discard unrelated user changes.
3. **If meaningfully different** (your fix addresses something self-healing missed) → proceed with the Apply Locally + Enhance Flow
Self-healing fixes go through proper CI verification. Always prefer the self-healing path when fixes overlap.
### Apply vs Reject vs Apply Locally
- **Apply via MCP**: Calls `update_self_healing_fix({ shortLink, action: "APPLY" })`. Self-healing agent applies the fix in CI and a new CI Attempt spawns automatically. No local git operations needed.
- **Apply Locally**: Runs `nx-cloud apply-locally <shortLink>`. Applies the patch to your local working directory and sets state to `APPLIED_LOCALLY`. Use this when you want to enhance the fix before pushing.
- **Reject via MCP**: Calls `update_self_healing_fix({ shortLink, action: "REJECT" })`. Marks fix as rejected. Use only when the fix is completely wrong and you'll fix from scratch.
### Apply Locally + Enhance Flow
When the fix needs enhancement (use `nx-cloud apply-locally`, NOT reject):
1. Apply the patch locally: `nx-cloud apply-locally <shortLink>` (this also updates state to `APPLIED_LOCALLY`)
2. Make additional changes as needed
3. Stage only the files you modified: `git add <file1> <file2> ...`
4. Commit and push:
```bash
git commit -m "fix: resolve <failedTaskIds>"
git push origin $(git branch --show-current)
```
5. Loop to poll for new CI Attempt
### Reject + Fix From Scratch Flow
When the fix is completely wrong:
1. Call MCP to reject: `update_self_healing_fix({ shortLink, action: "REJECT" })`
2. Fix the issue from scratch locally
3. Stage only the files you modified: `git add <file1> <file2> ...`
4. Commit and push:
```bash
git commit -m "fix: resolve <failedTaskIds>"
git push origin $(git branch --show-current)
```
5. Loop to poll for new CI Attempt
### Environment Issue Handling
When `failureClassification == 'ENVIRONMENT_STATE'`:
1. Call MCP to request rerun: `update_self_healing_fix({ shortLink, action: "RERUN_ENVIRONMENT_STATE" })`
2. New CI Attempt spawns automatically (no local git operations needed)
3. Loop to poll for new CI Attempt with `previousCipeUrl` set
### No-New-CI-Attempt Handling
When `status == 'no_new_cipe'`:
This means the expected CI Attempt was never created - CI likely failed before Nx tasks could run.
1. **Report to user:**
```
[monitor-ci] No CI attempt for <sha> after 10 min. Check CI provider for pre-Nx failures (install, checkout, auth). Last CI attempt: <previousCipeUrl>
```
2. **If user configured auto-fix attempts** (e.g., `--auto-fix-workflow`):
- Detect package manager: check for `pnpm-lock.yaml`, `yarn.lock`, `package-lock.json`
- Run install to update lockfile:
```bash
pnpm install # or npm install / yarn install
```
- If lockfile changed:
```bash
git add pnpm-lock.yaml # or appropriate lockfile
git commit -m "chore: update lockfile"
git push origin $(git branch --show-current)
```
- Record new commit SHA, loop to poll with `expectedCommitSha`
3. **Otherwise:** Exit with `no_new_cipe` status, providing guidance for user to investigate
### CI-Attempt-No-Tasks Handling
When `status == 'cipe_no_tasks'`:
This means the CI Attempt was created but no Nx tasks were recorded before it failed. Common causes:
- CI timeout before tasks could run
- Critical infrastructure error
- Memory/resource exhaustion
- Network issues connecting to Nx Cloud
1. **Report to user:**
```
[monitor-ci] CI failed but no Nx tasks were recorded.
[monitor-ci] CI Attempt URL: <cipeUrl>
[monitor-ci]
[monitor-ci] This usually indicates an infrastructure issue. Attempting retry...
```
2. **Create empty commit to retry CI:**
```bash
git commit --allow-empty -m "chore: retry ci [monitor-ci]"
git push origin $(git branch --show-current)
```
3. **Record `expected_commit_sha`, spawn subagent in wait mode**
4. **If retry also returns `cipe_no_tasks`:**
- Exit with failure
- Provide guidance:
```
[monitor-ci] Retry failed. Please check:
[monitor-ci] 1. Nx Cloud UI: <cipeUrl>
[monitor-ci] 2. CI provider logs (GitHub Actions, GitLab CI, etc.)
[monitor-ci] 3. CI job timeout settings
[monitor-ci] 4. Memory/resource limits
```
## Exit Conditions
Exit the monitoring loop when ANY of these conditions are met:
| Condition | Exit Type |
| ------------------------------------------------------------ | ---------------------- |
| CI passes (`cipeStatus == 'SUCCEEDED'`) | Success |
| Max agent-initiated cycles reached (after user declines ext) | Timeout |
| Max duration reached | Timeout |
| 3 consecutive no-progress iterations | Circuit breaker |
| No fix available and local fix not possible | Failure |
| No new CI Attempt and auto-fix not configured | Pre-CI-Attempt failure |
| User cancels | Cancelled |
## Main Loop
### Step 1: Initialize Tracking
```
cycle_count = 0 # Only incremented for agent-initiated cycles (counted against --max-cycles)
start_time = now()
no_progress_count = 0
local_verify_count = 0
last_state = null
last_cipe_url = null
expected_commit_sha = null
agent_triggered = false # Set true after monitor takes an action that triggers new CI Attempt
```
### Step 2: Spawn Subagent and Monitor Output
Spawn the `ci-monitor-subagent` subagent to poll CI status. **Run in background** so you can actively monitor and relay its output to the user.
**Fresh start (first spawn, no expected CI Attempt):**
```
Task(
agent: "ci-monitor-subagent",
run_in_background: true,
prompt: "Monitor CI for branch '<branch>'.
Subagent timeout: <subagent-timeout> minutes.
New-CI-Attempt timeout: <new-cipe-timeout> minutes.
Verbosity: <verbosity>."
)
```
**After action that triggers new CI Attempt (wait mode):**
```
Task(
agent: "ci-monitor-subagent",
run_in_background: true,
prompt: "Monitor CI for branch '<branch>'.
Subagent timeout: <subagent-timeout> minutes.
New-CI-Attempt timeout: <new-cipe-timeout> minutes.
Verbosity: <verbosity>.
WAIT MODE: A new CI Attempt should spawn. Ignore old CI Attempt until new one appears.
Expected commit SHA: <expected_commit_sha>
Previous CI Attempt URL: <last_cipe_url>"
)
```
### Step 2a: Active Output Monitoring (CRITICAL)
**The subagent's text output is NOT visible to users when running in background.** You MUST actively monitor and relay its output. Do NOT passively wait for completion.
After spawning the background subagent, enter a monitoring loop:
1. **Every 60 seconds**, check the subagent output using `TaskOutput(task_id, block=false)`
2. **Parse new lines** since your last check — look for `[ci-monitor]` and `⚡` prefixed lines
3. **Relay to user** based on verbosity:
- `minimal`: Only relay `⚡` critical transition lines
- `medium`: Relay all `[ci-monitor]` status lines
- `verbose`: Relay all subagent output
4. **Continue** until `TaskOutput` returns a completed status
5. When complete, proceed to Step 3 with the final subagent response
**Example monitoring loop output:**
```
[monitor-ci] Checking subagent status... (elapsed: 1m)
[monitor-ci] CI: IN_PROGRESS | Self-healing: NOT_STARTED
[monitor-ci] Checking subagent status... (elapsed: 3m)
[monitor-ci] CI: FAILED | Self-healing: IN_PROGRESS
[monitor-ci] ⚡ CI failed — self-healing fix generation started
[monitor-ci] Checking subagent status... (elapsed: 5m)
[monitor-ci] CI: FAILED | Self-healing: COMPLETED | Verification: IN_PROGRESS
[monitor-ci] ⚡ Self-healing fix generated — verification started
```
**NEVER do this:**
- Spawn subagent and passively say "Waiting for results..."
- Check once and say "Still working, I'll wait"
- Only show output when the subagent finishes
- Independently analyze CI failures, read task output, or attempt fixes while subagent is polling
**While the subagent is polling, your ONLY job is to relay its output.** Do not read CI task output, diagnose failures, generate fixes, modify code, or run tasks locally. All fix decisions happen in Step 3 AFTER the subagent returns with a status. Self-healing may already be working on a fix — independent local analysis races with it and causes duplicate/conflicting fixes.
### Step 3: Handle Subagent Response
When subagent returns:
1. Check the returned status
2. Look up default behavior in the table above
3. Check if user instructions override the default
4. Execute the appropriate action
5. **If action expects new CI Attempt**, update tracking (see Step 3a)
6. If action results in looping, go to Step 2
### Step 3a: Track State for New-CI-Attempt Detection
After actions that should trigger a new CI Attempt, record state before looping:
| Action | What to Track | Subagent Mode |
| ----------------------------------- | --------------------------------------------- | ------------- |
| Fix auto-applying | `last_cipe_url = current cipeUrl` | Wait mode |
| Apply via MCP | `last_cipe_url = current cipeUrl` | Wait mode |
| Apply locally + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| Reject + fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| Fix failed + local fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| No fix + local fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| Environment rerun | `last_cipe_url = current cipeUrl` | Wait mode |
| No-new-CI-Attempt + auto-fix + push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
| CI Attempt no tasks + retry push | `expected_commit_sha = $(git rev-parse HEAD)` | Wait mode |
**CRITICAL**: When passing `expectedCommitSha` or `last_cipe_url` to the subagent, it enters **wait mode**:
- Subagent will **completely ignore** the old/stale CI Attempt
- Subagent will only wait for new CI Attempt to appear
- Subagent will NOT return to main agent with stale CI Attempt data
- Once new CI Attempt detected, subagent switches to normal polling
**Why wait mode matters for context preservation**: Stale CI Attempt data can be very large (task output summaries, suggested fix patches, reasoning). If subagent returns this to main agent, it pollutes main agent's context with useless data since we already processed that CI Attempt. Wait mode keeps stale data in the subagent, never sending it to main agent.
### Step 4: Cycle Classification and Progress Tracking
#### Cycle Classification
Not all cycles are equal. Only count cycles the monitor itself triggered toward `--max-cycles`:
1. **After subagent returns**, check `agent_triggered`:
- `agent_triggered == true` → this cycle was triggered by the monitor → `cycle_count++`
- `agent_triggered == false` → this cycle was human-initiated or a first observation → do NOT increment `cycle_count`
2. **Reset** `agent_triggered = false`
3. **After Step 3a** (when the monitor takes an action that triggers a new CI Attempt) → set `agent_triggered = true`
**How detection works**: Step 3a is only called when the monitor explicitly pushes code, applies a fix via MCP, or triggers an environment rerun. If a human pushes on their own, the subagent detects a new CI Attempt but the monitor never went through Step 3a, so `agent_triggered` remains `false`.
**When a human-initiated cycle is detected**, log it:
```
[monitor-ci] New CI Attempt detected (human-initiated push). Monitoring without incrementing cycle count. (agent cycles: N/max-cycles)
```
#### Approaching Limit Gate
When `cycle_count >= max_cycles - 2`, pause and ask the user before continuing:
```
[monitor-ci] Approaching cycle limit (cycle_count/max_cycles agent-initiated cycles used).
[monitor-ci] How would you like to proceed?
1. Continue with 5 more cycles
2. Continue with 10 more cycles
3. Stop monitoring
```
Increase `max_cycles` by the user's choice and continue.
#### Progress Tracking
After each action:
- If state changed significantly → reset `no_progress_count = 0`
- If state unchanged → `no_progress_count++`
- On new CI attempt detected → reset `local_verify_count = 0`
## Status Reporting
Based on verbosity level:
| Level | What to Report |
| --------- | -------------------------------------------------------------------------- |
| `minimal` | Only final result (success/failure/timeout) |
| `medium` | State changes + periodic updates ("Cycle N \| Elapsed: Xm \| Status: ...") |
| `verbose` | All of medium + full subagent responses, git outputs, MCP responses |
## User Instruction Examples
Users can override default behaviors:
| Instruction | Effect |
| ------------------------------------------------ | --------------------------------------------------- |
| "never auto-apply" | Always prompt before applying any fix |
| "always ask before git push" | Prompt before each push |
| "reject any fix for e2e tasks" | Auto-reject if `failedTaskIds` contains e2e |
| "apply all fixes regardless of verification" | Skip verification check, apply everything |
| "if confidence < 70, reject" | Check confidence field before applying |
| "run 'nx affected -t typecheck' before applying" | Add local verification step |
| "auto-fix workflow failures" | Attempt lockfile updates on pre-CI-Attempt failures |
| "wait 45 min for new CI Attempt" | Override new-CI-Attempt timeout (default: 10 min) |
## Error Handling
| Error | Action |
| ------------------------------ | ------------------------------------------------------------------------------------- |
| Git rebase conflict | Report to user, exit |
| `nx-cloud apply-locally` fails | Report to user, attempt manual patch or exit |
| MCP tool error | Retry once, if fails report to user |
| Subagent spawn failure | Retry once, if fails exit with error |
| No new CI Attempt detected | If `--auto-fix-workflow`, try lockfile update; otherwise report to user with guidance |
| Lockfile auto-fix fails | Report to user, exit with guidance to check CI logs |

Trigger words - scaffold, setup, create a ... app, create a ... lib, project structure, generate, add a new project.

# Run Nx Generator
Nx generators are powerful tools that scaffold projects, make automated code migrations or automate repetitive tasks in a monorepo. They ensure consistency across the codebase and reduce boilerplate work.
This skill applies when the user wants to:
- Create new projects like libraries or applications
- Scaffold features or boilerplate code
- Run workspace-specific or custom generators
- Do anything else that an nx generator exists for
## Key Principles
1. **Always use `--no-interactive`** - Prevents prompts that would hang execution
2. **Read the generator source code** - The schema alone is not enough; understand what the generator actually does
3. **Match existing repo patterns** - Study similar artifacts in the repo and follow their conventions
4. **Verify with lint/test/build/typecheck etc.** - Generated code must pass verification. The listed targets are just an example, use what's appropriate for this workspace.
## Steps
### 1. Discover Available Generators
Use the Nx CLI to discover available generators:
- List all generators for a plugin: `npx nx list @nx/react`
- View available plugins: `npx nx list`
This includes plugin generators (e.g., `@nx/react:library`) and local workspace generators.
### 2. Match Generator to User Request
Identify which generator(s) could fulfill the user's needs. Consider what artifact type they want, which framework is relevant, and any specific generator names mentioned.
**IMPORTANT**: When both a local workspace generator and an external plugin generator could satisfy the request, **always prefer the local workspace generator**. Local generators are customized for the specific repo's patterns.
If no suitable generator exists, you can stop using this skill. However, the burden of proof is high—carefully consider all available generators before deciding none apply.
### 3. Get Generator Options
Use the `--help` flag to understand available options:
```bash
npx nx g @nx/react:library --help
```
Pay attention to required options, defaults that might need overriding, and options relevant to the user's request.
### Library Buildability
**Default to non-buildable libraries** unless there's a specific reason for buildable.
| Type | When to use | Generator flags |
| --------------------------- | ----------------------------------------------------------------- | ----------------------------------- |
| **Non-buildable** (default) | Internal monorepo libs consumed by apps | No `--bundler` flag |
| **Buildable** | Publishing to npm, cross-repo sharing, stable libs for cache hits | `--bundler=vite` or `--bundler=swc` |
Non-buildable libs:
- Export `.ts`/`.tsx` source directly
- Consumer's bundler compiles them
- Faster dev experience, less config
Buildable libs:
- Have their own build target
- Useful for stable libs that rarely change (cache hits)
- Required for npm publishing
**If unclear, ask the user:** "Should this library be buildable (own build step, better caching) or non-buildable (source consumed directly, simpler setup)?"
### 4. Read Generator Source Code
**This step is critical.** The schema alone does not tell you everything. Reading the source code helps you:
- Know exactly what files will be created/modified and where
- Understand side effects (updating configs, installing deps, etc.)
- Identify behaviors and options not obvious from the schema
- Understand how options interact with each other
To find generator source code:
- For plugin generators: Use `node -e "console.log(require.resolve('@nx/<plugin>/generators.json'));"` to find the generators.json, then locate the source from there
- If that fails, read directly from `node_modules/<plugin>/generators.json`
- For local generators: Typically in `tools/generators/` or a local plugin directory. Search the repo for the generator name.
After reading the source, reconsider: Is this the right generator? If not, go back to step 2.
> **⚠️ `--directory` flag behavior can be misleading.**
> It should specify the full path of the generated library or component, not the parent path that it will be generated in.
>
> ```bash
> # ✅ Correct - directory is the full path for the library
> nx g @nx/react:library --directory=packages/my-lib
> # generates packages/my-lib/package.json and more
>
> # ❌ Wrong - this will create files at libs and packages/src/...
> nx g @nx/react:library --name=my-lib --directory=libs
> # generates packages/package.json and more
> ```
### 5. Examine Existing Patterns
Before generating, examine the target area of the codebase:
- Look at similar existing artifacts (other libraries, applications, etc.)
- Identify naming conventions, file structures, and configuration patterns
- Note which test runners, build tools, and linters are used
- Configure the generator to match these patterns
### 6. Dry-Run to Verify File Placement
**Always run with `--dry-run` first** to verify files will be created in the correct location:
```bash
npx nx g @nx/react:library --name=my-lib --dry-run --no-interactive
```
Review the output carefully. If files would be created in the wrong location, adjust your options based on what you learned from the generator source code.
Note: Some generators don't support dry-run (e.g., if they install npm packages). If dry-run fails for this reason, proceed to running the generator for real.
### 7. Run the Generator
Execute the generator:
```bash
nx generate <generator-name> <options> --no-interactive
```
> **Tip:** New packages often need workspace dependencies wired up (e.g., importing shared types, being consumed by apps). The `link-workspace-packages` skill can help add these correctly.
### 8. Modify Generated Code (If Needed)
Generators provide a starting point. Modify the output as needed to:
- Add or modify functionality as requested
- Adjust imports, exports, or configurations
- Integrate with existing code patterns
**Important:** If you replace or delete generated test files (e.g., `*.spec.ts`), either write meaningful replacement tests or remove the `test` target from the project configuration. Empty test suites will cause `nx test` to fail.
### 9. Format and Verify
Format all generated/modified files:
```bash
nx format --fix
```
This example is for built-in nx formatting with prettier. There might be other formatting tools for this workspace, use these when appropriate.
Then verify the generated code works. Keep in mind that the changes you make with a generator or subsequent modifications might impact various projects so it's usually not enough to only run targets for the artifact you just created.
```bash
# these targets are just an example!
nx run-many -t build,lint,test,typecheck
```
These targets are common examples used across many workspaces. You should do research into other targets available for this workspace and its projects. CI configuration is usually a good guide for what the critical targets are that have to pass.
If verification fails with manageable issues (a few lint errors, minor type issues), fix them. If issues are extensive, attempt obvious fixes first, then escalate to the user with details about what was generated, what's failing, and what you've attempted.

name: nx-run-tasks
description: Helps with running tasks in an Nx workspace. USE WHEN the user wants to execute build, test, lint, serve, or run any other tasks defined in the workspace.
---
You can run tasks with Nx in the following way.
Keep in mind that you might have to prefix things with npx/pnpx/yarn if the user doesn't have nx installed globally. Look at the package.json or lockfile to determine which package manager is in use.
For more details on any command, run it with `--help` (e.g. `nx run-many --help`, `nx affected --help`).
## Understand which tasks can be run
You can check those via `nx show project <projectname> --json`, for example `nx show project myapp --json`. It contains a `targets` section which has information about targets that can be run. You can also just look at the `package.json` scripts or `project.json` targets, but you might miss out on inferred tasks by Nx plugins.
## Run a single task
```
nx run <project>:<task>
```
where `project` is the project name defined in `package.json` or `project.json` (if present).
## Run multiple tasks
```
nx run-many -t build test lint typecheck
```
You can pass a `-p` flag to filter to specific projects, otherwise it runs on all projects. You can also use `--exclude` to exclude projects, and `--parallel` to control the number of parallel processes (default is 3).
Examples:
- `nx run-many -t test -p proj1 proj2` — test specific projects
- `nx run-many -t test --projects=*-app --exclude=excluded-app` — test projects matching a pattern
- `nx run-many -t test --projects=tag:api-*` — test projects by tag
## Run tasks for affected projects
Use `nx affected` to only run tasks on projects that have been changed and projects that depend on changed projects. This is especially useful in CI and for large workspaces.
```
nx affected -t build test lint
```
By default it compares against the base branch. You can customize this:
- `nx affected -t test --base=main --head=HEAD` — compare against a specific base and head
- `nx affected -t test --files=packages/mylib/src/index.ts` — specify changed files directly
## Useful flags
These flags work with `run`, `run-many`, and `affected`:
- `--skipNxCache` — rerun tasks even when results are cached
- `--verbose` — print additional information such as stack traces
- `--nxBail` — stop execution after the first failed task
- `--configuration=<name>` — use a specific configuration (e.g. `production`)

# Nx Workspace Exploration
This skill provides read-only exploration of Nx workspaces. Use it to understand workspace structure, project configuration, available targets, and dependencies.
Keep in mind that you might have to prefix commands with `npx`/`pnpx`/`yarn` if nx isn't installed globally. Check the lockfile to determine the package manager in use.
## Listing Projects
Use `nx show projects` to list projects in the workspace.
The project filtering syntax (`-p`/`--projects`) works across many Nx commands including `nx run-many`, `nx release`, `nx show projects`, and more. Filters support explicit names, glob patterns, tag references (e.g. `tag:name`), directories, and negation (e.g. `!project-name`).
```bash
# List all projects
nx show projects
# Filter by pattern (glob)
nx show projects --projects "apps/*"
nx show projects --projects "shared-*"
# Filter by tag
nx show projects --projects "tag:publishable"
nx show projects -p 'tag:publishable,!tag:internal'
# Filter by target (projects that have a specific target)
nx show projects --withTarget build
# Combine filters
nx show projects --type lib --withTarget test
nx show projects --affected --exclude="*-e2e"
nx show projects -p "tag:scope:client,packages/*"
# Negate patterns
nx show projects -p '!tag:private'
nx show projects -p '!*-e2e'
# Output as JSON
nx show projects --json
```
## Project Configuration
Use `nx show project <name> --json` to get the full resolved configuration for a project.
**Important**: Do NOT read `project.json` directly - it only contains partial configuration. The `nx show project --json` command returns the full resolved config including inferred targets from plugins.
You can read the full project schema at `node_modules/nx/schemas/project-schema.json` to understand nx project configuration options.
```bash
# Get full project configuration
nx show project my-app --json
# Extract specific parts from the JSON
nx show project my-app --json | jq '.targets'
nx show project my-app --json | jq '.targets.build'
nx show project my-app --json | jq '.targets | keys'
# Check project metadata
nx show project my-app --json | jq '{name, root, sourceRoot, projectType, tags}'
```
## Target Information
Targets define what tasks can be run on a project.
```bash
# List all targets for a project
nx show project my-app --json | jq '.targets | keys'
# Get full target configuration
nx show project my-app --json | jq '.targets.build'
# Check target executor/command
nx show project my-app --json | jq '.targets.build.executor'
nx show project my-app --json | jq '.targets.build.command'
# View target options
nx show project my-app --json | jq '.targets.build.options'
# Check target inputs/outputs (for caching)
nx show project my-app --json | jq '.targets.build.inputs'
nx show project my-app --json | jq '.targets.build.outputs'
# Find projects with a specific target
nx show projects --withTarget serve
nx show projects --withTarget e2e
```
## Workspace Configuration
Read `nx.json` directly for workspace-level configuration.
You can read the full project schema at `node_modules/nx/schemas/nx-schema.json` to understand nx project configuration options.
```bash
# Read the full nx.json
cat nx.json
# Or use jq for specific sections
cat nx.json | jq '.targetDefaults'
cat nx.json | jq '.namedInputs'
cat nx.json | jq '.plugins'
cat nx.json | jq '.generators'
```
Key nx.json sections:
- `targetDefaults` - Default configuration applied to all targets of a given name
- `namedInputs` - Reusable input definitions for caching
- `plugins` - Nx plugins and their configuration
- ...and much more, read the schema or nx.json for details
## Affected Projects
If the user is asking about affected projects, read the [affected projects reference](references/AFFECTED.md) for detailed commands and examples.
## Common Exploration Patterns
### "What's in this workspace?"
```bash
nx show projects
nx show projects --type app
nx show projects --type lib
```
### "How do I build/test/lint project X?"
```bash
nx show project X --json | jq '.targets | keys'
nx show project X --json | jq '.targets.build'
```
### "What depends on library Y?"
```bash
# Use the project graph to find dependents
nx graph --print | jq '.graph.dependencies | to_entries[] | select(.value[].target == "Y") | .key'
```
## Programmatic Answers
When processing nx CLI results, use command-line tools to compute the answer programmatically rather than counting or parsing output manually. Always use `--json` flags to get structured output that can be processed with `jq`, `grep`, or other tools you have installed locally.
### Listing Projects
```bash
nx show projects --json
```
Example output:
```json
["my-app", "my-app-e2e", "shared-ui", "shared-utils", "api"]
```
Common operations:
```bash
# Count projects
nx show projects --json | jq 'length'
# Filter by pattern
nx show projects --json | jq '.[] | select(startswith("shared-"))'
# Get affected projects as array
nx show projects --affected --json | jq '.'
```
### Project Details
```bash
nx show project my-app --json
```
Example output:
```json
{
"root": "apps/my-app",
"name": "my-app",
"sourceRoot": "apps/my-app/src",
"projectType": "application",
"tags": ["type:app", "scope:client"],
"targets": {
"build": {
"executor": "@nx/vite:build",
"options": { "outputPath": "dist/apps/my-app" }
},
"serve": {
"executor": "@nx/vite:dev-server",
"options": { "buildTarget": "my-app:build" }
},
"test": {
"executor": "@nx/vite:test",
"options": {}
}
},
"implicitDependencies": []
}
```
Common operations:
```bash
# Get target names
nx show project my-app --json | jq '.targets | keys'
# Get specific target config
nx show project my-app --json | jq '.targets.build'
# Get tags
nx show project my-app --json | jq '.tags'
# Get project root
nx show project my-app --json | jq -r '.root'
```
### Project Graph
```bash
nx graph --print
```
Example output:
```json
{
"graph": {
"nodes": {
"my-app": {
"name": "my-app",
"type": "app",
"data": { "root": "apps/my-app", "tags": ["type:app"] }
},
"shared-ui": {
"name": "shared-ui",
"type": "lib",
"data": { "root": "packages/shared-ui", "tags": ["type:ui"] }
}
},
"dependencies": {
"my-app": [{ "source": "my-app", "target": "shared-ui", "type": "static" }],
"shared-ui": []
}
}
}
```
Common operations:
```bash
# Get all project names from graph
nx graph --print | jq '.graph.nodes | keys'
# Find dependencies of a project
nx graph --print | jq '.graph.dependencies["my-app"]'
# Find projects that depend on a library
nx graph --print | jq '.graph.dependencies | to_entries[] | select(.value[].target == "shared-ui") | .key'
```
## Troubleshooting
### "Cannot find configuration for task X:target"
```bash
# Check what targets exist on the project
nx show project X --json | jq '.targets | keys'
# Check if any projects have that target
nx show projects --withTarget target
```
### "The workspace is out of sync"
```bash
nx sync
nx reset # if sync doesn't fix stale cache
```
