# Monitor CI Command

You are the orchestrator for monitoring Nx Cloud CI pipeline executions and handling self-healing fixes. You spawn subagents to interact with Nx Cloud, run deterministic decision scripts, and take action 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                                                         |
| `--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

Before starting the monitoring loop, verify the workspace is connected to Nx Cloud. Without this connection, no CI data is available and the entire skill is inoperable.

### 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:

   ```
   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

## Architecture Overview

1. **This skill (orchestrator)**: spawns subagents, runs scripts, prints status, does local coding work
2. **ci-monitor-subagent (haiku)**: calls one MCP tool (ci_information or update_self_healing_fix), returns structured result, exits
3. **ci-poll-decide.mjs (deterministic script)**: takes ci_information result + state, returns action + status message
4. **ci-state-update.mjs (deterministic script)**: manages budget gates, post-action state transitions, and cycle classification

## Status Reporting

The decision script handles message formatting based on verbosity. When printing messages to the user:

- Prepend `[monitor-ci]` to every message from the script's `message` field
- For your own action messages (e.g. "Applying fix via MCP..."), also prepend `[monitor-ci]`

## Anti-Patterns

These behaviors cause real problems — racing with self-healing, losing CI progress, or wasting context:

| 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 polling                                        | 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 a one-time, read-only status check (single call, no watch/polling flags)
2. Immediately delegate to this skill with gathered context
3. Do not continue polling on main agent — it wastes context tokens and bypasses self-healing

## Session Context Behavior

If the user previously ran `/monitor-ci` in this session, you may have prior state (poll counts, last CI Attempt URL, etc.). Resume from that state unless `--fresh` is set, in which case discard it and start from Step 1.

## MCP Tool Reference

Three field sets control polling efficiency — use the lightest set that gives you what you need:

```yaml
WAIT_FIELDS: 'cipeUrl,commitSha,cipeStatus'
LIGHT_FIELDS: 'cipeStatus,cipeUrl,branch,commitSha,selfHealingStatus,verificationStatus,userAction,failedTaskIds,verifiedTaskIds,selfHealingEnabled,failureClassification,couldAutoApplyTasks,autoApplySkipped,autoApplySkipReason,shortLink,confidence,confidenceReasoning,hints,selfHealingSkippedReason,selfHealingSkipMessage'
HEAVY_FIELDS: 'taskOutputSummary,suggestedFix,suggestedFixReasoning,suggestedFixDescription'
```

The `ci_information` tool accepts `branch` (optional, defaults to current git branch), `select` (comma-separated field names), and `pageToken` (0-based pagination for long strings).

The `update_self_healing_fix` tool accepts a `shortLink` and an action: `APPLY`, `REJECT`, or `RERUN_ENVIRONMENT_STATE`.

## Default Behaviors by Status

The decision script returns one of the following statuses. This table defines the **default behavior** for each. User instructions can override any of these.

**Simple exits** — just report and exit:

| Status                  | Default Behavior                                                                                                 |
| ----------------------- | ---------------------------------------------------------------------------------------------------------------- |
| `ci_success`            | Exit with success                                                                                                |
| `cipe_canceled`         | Exit, CI was canceled                                                                                            |
| `cipe_timed_out`        | Exit, CI timed out                                                                                               |
| `polling_timeout`       | Exit, polling timeout reached                                                                                    |
| `circuit_breaker`       | Exit, no progress after 13 consecutive polls                                                                     |
| `environment_rerun_cap` | Exit, environment reruns exhausted                                                                               |
| `fix_auto_applying`     | Self-healing is handling it — just record `last_cipe_url`, enter wait mode. No MCP call or local git ops needed. |
| `error`                 | Wait 60s and loop                                                                                                |

**Statuses requiring action** — when handling these in Step 3, read `references/fix-flows.md` for the detailed flow:

| Status                   | Summary                                                                                       |
| ------------------------ | --------------------------------------------------------------------------------------------- |
| `fix_auto_apply_skipped` | Fix verified but auto-apply skipped (e.g., loop prevention). Inform user, offer manual apply. |
| `fix_apply_ready`        | Fix verified (all tasks or e2e-only). Apply via MCP.                                          |
