Await Polygraph CI

Wait for all CI pipelines in a Polygraph session to reach a stable state (succeeded, failed, etc.), then produce a unified summary. If any pipelines failed, investigate via child agents and present fix options.

Some Polygraph tools have both MCP and CLI equivalents — use whichever is available in your environment. See the polygraph skill's tool table for the full mapping.

Phase 1: Session Setup

Fetch the Polygraph session using show_session.

Parameters:

• sessionId (required): The Polygraph session ID

show_session(sessionId: "<session-id>")

1. Record monitorStartedAt = current timestamp (epoch millis).
2. Build a tracking table of all repos with PRs. For each PR, record:
   • repo: repository name
   • prUrl: PR URL
   • prStatus: DRAFT / OPEN / MERGED / CLOSED
   • ciStatus: from session (may already be a terminal status from a previous run)
   • cipeUrl: CI pipeline URL (null if none)
   • cipeCompletedAt: completedAt from session (epoch millis, null if CIPE is active or absent)
   • selfHealingStatus: self-healing fix status (null if none)
   • firstSeenAt: current timestamp
3. If no PRs found, report "No PRs in session" and exit.
4. Stale detection: For each PR, determine if its CI status is stale — meaning it reflects a previous run, not a current one. A PR's CI status is stale if:
   • cipeCompletedAt is non-null AND cipeCompletedAt < monitorStartedAt (the CIPE finished before the monitor started)
   • Mark these PRs as stale: true
5. Display the initial status table, annotating stale PRs:

   backend: SUCCEEDED (stale) | frontend: SUCCEEDED (stale) | shared-lib: NOT_STARTED
   

Phase 2: Polling Loop

Configuration:

• Timeout: 30 minutes total
• Backoff: 60s → 90s → 120s (cap)
• Circuit breaker: exit after 5 consecutive polls with no status change

Each poll iteration:

1. Call show_session(sessionId: <session-id>)
2. Update each tracked PR from the session response: ciStatus, cipeUrl, cipeCompletedAt, and selfHealingStatus
3. Clear stale flag: If a PR was marked stale: true and its cipeCompletedAt has changed (or become null, meaning a new CIPE is active), clear the stale flag — this PR now has fresh CI data.
4. Display status update:

   [await-polygraph-ci] Poll #N | Elapsed: Xm | Repos: Y total, Z completed
    backend: SUCCEEDED | frontend: FAILED (self-healing: PENDING) | shared-lib: SUCCEEDED (stale)
   

   Include selfHealingStatus inline when non-null. Annotate stale PRs.
5. Check exclusion rule: if a PR has prStatus: DRAFT and ciStatus: NOT_STARTED for more than 5 minutes since firstSeenAt, mark it as EXCLUDED (DRAFT PRs may not trigger CI)
6. Check terminal conditions — a PR is terminal when:
   • It is NOT stale, AND:
     • CI status is SUCCEEDED, CANCELED, or TIMED_OUT, OR
     • CI status is FAILED AND there is no active self-healing (i.e., selfHealingStatus is null or a final state like APPLIED, REJECTED, FAILED)
   • A FAILED PR with selfHealingStatus indicating an in-progress fix (e.g., PENDING, IN_PROGRESS) is NOT terminal — keep polling to track the self-healing outcome
   • A stale PR is NOT terminal — keep polling until it gets a fresh CIPE or is excluded
7. Stale timeout: If a stale PR remains stale for more than 5 minutes, assume no new CI is expected for it. Clear the stale flag and treat its current status as final.
8. If all non-excluded PRs are terminal → proceed to Phase 3
9. If timeout or circuit breaker hit → proceed to Phase 3 with partial results
10. Otherwise → wait with backoff, then poll again

Phase 3: Results Analysis

Categorize repos into: succeeded, failed, canceled, timed_out, excluded, in_progress (if timed out).

Display final summary table. When showing self-healing status, distinguish clearly between these states:

• COMPLETED = a fix was generated and verified, but NOT yet applied. Display as fix available.
• APPLIED = the fix was applied by the user or agent. Display as fix applied, awaiting re-run.
• IN_PROGRESS / PENDING = the fix is still being generated. Display as in progress.
• REJECTED = the fix was rejected. Display as fix rejected.
• FAILED = self-healing failed to produce a fix. Display as fix failed.

[await-polygraph-ci] Final Results | Elapsed: Xm
 SUCCEEDED: backend, shared-lib
 FAILED: frontend (self-healing: fix available)
 EXCLUDED: docs (DRAFT, no CI)

Include self-healing status for any repo that has one.

• If all succeeded → report success and exit
• If any failed with selfHealingStatus: APPLIED, inform the user that the fix was applied and a CI re-run may be in progress or needed
• If any failed with selfHealingStatus: COMPLETED, inform the user that a fix is available but not yet applied, and offer to apply it
• If any failed → proceed to Phase 4

Phase 4: Failure Investigation (Child Agent Delegation)

For each repo with ciStatus: FAILED, first check the CI data source from ciStatus[prId]:

• If cipeUrl is non-null → CIPE is authoritative. Delegate investigation using ci_information.
• If cipeUrl is null but externalCIRuns exists → external CI only. Examine failed jobs from externalCIRuns in the session data and use get_ci_logs for log retrieval. {% if platform == "codex" %}

Codex subagent wrapper: Use polygraph-delegate-subagent to keep the Polygraph MCP spawn_agent / show_agent polling loop out of the main conversation. For each failed repo, launch a Codex spawn_agent with agent_type: "polygraph-delegate-subagent" and instructions to perform steps 2-4 below for that repo, then collect completed summaries with wait_agent when the main flow needs them. In the steps below, spawn_agent and show_agent refer to the Polygraph MCP tools that belong inside the Codex subagent. {% endif %}

1. Display known info from the session data before delegating:

   Repository: frontend
   CI Source: <CIPE or External CI (GitHub Actions)>
   CI Pipeline: <cipeUrl from session, or GitHub Actions run URL>
   Self-healing: <selfHealingStatus from session, or "None">
   Investigating failure details...
   

2. Delegate investigation (non-blocking) — call spawn_agent for each failed repo:

   • sessionId: the session ID
   • repo: the repository name
   • instruction (when CIPE exists): Use the ci_information tool to investigate the CI failure on this branch. Return a structured summary with: (1) list of failed task IDs with a one-line error summary each, (2) failure category (Build / Test / Lint / E2E / Infra / Other).
   • instruction (when no CIPE, external CI only): The session data shows external CI failures with these failed jobs: [list jobId + name from externalCIRuns[].jobs where conclusion is failure]. Use get_ci_logs(sessionId, repoId, jobId) to save the log for each failed job to a local file, then use the Read tool to examine the log file contents. Return a structured summary with: (1) one-line error summary per failed job, (2) failure category (Build / Test / Lint / E2E / Infra / Other), (3) relevant log excerpts.
   • context: Polygraph session monitoring — investigating CI failure for unified summary. The repository ID for this repo is available from the session data.

   Since spawn_agent is non-blocking, you can delegate to multiple failed repos in parallel.

3. Monitor investigation progress — poll show_agent to wait for each child agent to complete:

   show_agent(sessionId: "<session-id>", repo: "frontend")
   

   Poll until the child agent's status indicates completion. Use the tail parameter to retrieve recent output lines containing the investigation results.

4. Collect each child agent's response from the status output. If a child agent fails or gets stuck, use stop_agent to terminate it and skip that repo.

5. Display failure summary for each repo:

   Repository: frontend
   CI Pipeline: <cipeUrl>
   Failed Tasks (2):
     - frontend:build → TypeScript error in src/app.tsx:42
     - frontend:test  → 3 test suites failed
   Category: Build + Test failures
   Self-healing: <selfHealingStatus>
   Job Logs: <number of logs retrieved, if any>
   

   If CI job logs were retrieved via get_ci_logs, include relevant excerpts (error messages, stack traces) in the summary. Keep excerpts concise — only the most relevant lines.

Phase 5: Fix Planning

1. Group failures by category (Build, Test, Lint, E2E, Infra)
2. Identify cross-repo dependency issues (e.g., shared-lib build failure blocking frontend)
3. Suggest fix order based on dependency graph (upstream repos first)
4. Present next actions to the user based on self-healing status:
   • If any repo has selfHealingStatus with an available fix → offer to apply self-healing via update_self_healing_fix(action: "APPLY") or reject it
   • If self-healing was already applied → offer to resume monitoring to watch the re-triggered CI
   • Delegate fixes: use Polygraph to send fix instructions to child agents (for repos without self-healing or where self-healing was rejected/failed)
   • Get more details: drill into a specific repo's failure
   • Exit: done monitoring

Notes

• This skill does NOT push code directly. The only write action it may take is applying/rejecting a self-healing fix via update_self_healing_fix, which is an Nx Cloud operation (not a local code change).
• Both ci_information and update_self_healing_fix responses include a hints array with contextual guidance (e.g., disclaimers about which CI Attempt was retrieved). Always check and surface non-empty hints.
• All heavy CI data inspection happens in child agents via spawn_agent to keep this context window clean. {% if platform == "codex" %}
• On Codex, the delegate-and-poll loop should run inside polygraph-delegate-subagent, and the main conversation should use wait_agent only when it needs to collect results. {% endif %}
• Child agents can use get_ci_logs to save CI job logs to local files, but ONLY when no CIPE exists for the PR (ciStatus[prId].cipeUrl is null). When a CIPE exists, logs come from the CIPE system via ci_information. Job IDs come from ciStatus[prId].externalCIRuns[].jobs[].jobId in the show_session response. The tool returns a file path (logFile) and size (sizeBytes) — use the Read tool to examine the log content. Logs can be large (100KB+), so only fetch logs for failed or relevant jobs.
• spawn_agent is non-blocking — it starts the child agent and returns immediately. Use show_agent to poll for results and stop_agent to terminate stuck agents.
• The show_session response is compact and safe to poll from the main agent.
