copilot-pr-autopilot

Copilot left 14 review comments on your PR — half are nits. Hours of fix → reply → resolve → re-request, and each round lands MORE comments. This skill runs loop engineering: auto-triggers Copilot Code Review via GraphQL (no @copilot mention), triages every open thread (Copilot, humans, advanced-security) with a fix / decline / escalate rubric, dispatches parallel fix sub-agents that obey the repo build/test/lint conventions, commits per iteration, replies+resolves citing the pushed SHA, then re-triggers until HEAD is reviewed with zero threads awaiting the agent's reply (remaining open threads are explicit hand-offs to the human — escalated declines, design tradeoffs). You merge a clean PR; the bot runs it. Trigger phrases: "address copilot comments", "run a copilot review loop", "fix this PR", "iterate on copilot feedback". Repo-agnostic, gh CLI + PowerShell. Full autopilot needs repo Triage/Write; external PR authors get single-iteration mode plus manual re-trigger (UI 🔄 or substantive-commit push).

Copilot PR Autopilot

Drive any GitHub pull request through repeated rounds of Copilot code review until the agent has done its job — every Copilot finding has a reply from the agent (fix-acknowledgement, decline-with-rationale, or explicit escalate-to-user hand-off). Remaining open threads, if any, are deliberate hand-offs to the human merge owner — they're not loop failures. Repository-agnostic — works on any repo that has Copilot Code Review enabled, run from a machine with gh CLI installed and authenticated (see Prerequisites).

When to Use This Skill

• The user asks to "request Copilot review" or "run a Copilot review loop" on a PR.
• A PR is functionally complete and the user wants a final correctness pass via repeated automated review rounds.
• A previous Copilot review on the PR has left open threads that need triage, fixing, replying, and resolving.

When NOT to Use This Skill

• The PR is still under active design — wait until the structure is stable; otherwise findings churn round-over-round.
• The user wants human reviewer feedback, not Copilot's.

Prerequisites

• gh CLI installed and authenticated against the target repository.
• PowerShell on PATH — Windows PowerShell 5.1+ (powershell.exe) or PowerShell 7+ (pwsh). Both are tested.
• Copilot Code Review is the primary use case (01-request-review.ps1 uses GraphQL requestReviewsByLogin to trigger Copilot). It is NOT a hard requirement — if 01-request-review.ps1 fails because Copilot isn't enabled on the repo / account, the agent can still drive existing review threads (human, advanced-security, etc.) to completion by running steps 3–8 once as a single iteration; just skip the trigger + wait. There is no auto-detect for "Copilot unavailable" — the agent makes that decision after the trigger fails (the script can't reliably tell "Copilot disabled" from "Copilot enabled but not yet triggered" from API state alone).

Permissions: who can run the full loop

The full multi-round autopilot (steps 1 → 9 → 1) needs Triage or Write permission on the target repo, because GitHub's only public API for adding the Copilot bot as a reviewer (requestReviewsByLogin) is gated on that permission. Verified against the public REST + GraphQL surface in this PR's commit history — there is no public-API path for bot reviewers without write permission.

You are…	What works
Repo collaborator with Triage / Write	Full loop: 01 triggers Copilot, 02 waits, 04–08 triage / fix / reply, loop back to 01. Hands-off.
External PR author (no write permission)	01 will throw a clear actionable error. Use -SingleIteration mode: address all current findings in one pass, then either click the UI 🔄 next to Copilot, or push a substantive commit (the synchronize event auto-triggers Copilot on most repos). Then re-run 02 to verify.

In single-iteration mode the loop's convergence boolean is Converged: true iff OpenThreadsAwaitingReply == 0 (the agent's side is done). The maintainer-side re-trigger then drives any additional rounds.

Every script dot-sources scripts/_lib.ps1 which runs Assert-GhReady on load: if gh is missing OR gh auth status fails, the script halts before any work with a single actionable error message naming the install command and gh auth login. The agent should surface that message to the user verbatim and stop the loop — do not retry or work around it.

Step-by-Step Workflow

The loop: steps 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9, then back to step 1 if Converged: false. Repeat the 1→9 round until step 9 returns Converged: true; only then run step 10 once and call task_complete. At every 10th round, the parent runs the round-cap recap gate before looping back — recap all prior rounds and stop if the loop has drifted out of the PR's original scope.

Each round runs steps 1–9; step 10 is a one-time cleanup after convergence. The parent agent coordinates; every sub-agent step runs in a fresh context with a bounded budget. Cross-cutting protocol (time-boxing, extension, single-iteration fallback): orchestration.md.

1. Request review (parent) — see 01-request-review.md
2. Wait for review (sub-agent, 20-min cap) — see 02-wait.md
3. List + categorize open threads (sub-agent, 5 min) — see 03-list-threads.md
4. Triage (sub-agent, 5 min per ≤5 threads) — see 04-triage.md
5. Fix (sub-agents, parallel max 5, 5 min each) — see 05-fix.md
6. Build + test per repo conventions (sub-agent, 10 min) — see 06-build-test.md
7. Commit + push (parent) — see 07-commit-push.md
8. Reply (always) + resolve (conditional) (sub-agent drafts, parent posts) — see 08-reply-resolve.md
9. Convergence verify (sub-agent, 3 min) — see 09-convergence.md
   • Converged: false → loop back to step 1 for another round (re-trigger, wait, list, triage, fix, push, reply, re-check). Each round addresses Copilot's findings on the previous round's HEAD; the loop terminates as soon as Copilot has nothing new to say AND every open thread has a reply from the agent.
   • Converged: true → exit the loop, run step 10 once, call task_complete with the proof.
   • Every 10th round (10, 20, 30…) → run the round-cap recap gate before looping back. Recap ALL prior rounds against the PR's original scope and pick a verdict: CONTINUE, REVERT-AND-SHIP (drop drifted commits, ship the in-scope ones), or HAND-OFF (escalate to the user). This is the circuit breaker that stops a runaway bot-review loop.
10. Cleanup outdated (parent, post-convergence, once) — see 10-cleanup.md

Convergence is computed by scripts/02-check-review-status.ps1 as a single Converged: true boolean. Do not call task_complete until it returns true; print the proof (HeadOid, LatestCopilotReview.commitOid, submittedAt) in the completion message.

Gotchas

The bundled scripts enforce the hard correctness invariants (trigger landing via copilot_work_started event id, Converged requiring HEAD-match + zero-awaiting + at-HEAD review, single-iteration fallback semantics, PR-state guard). Trust them — don't re-derive. The notes below cover decisions the scripts can't make for you:

• Reply to every open thread; resolve only when the loop owns the disposition. For fix and decline threads, reply + resolve. For escalate-to-user threads, reply with the analysis but leave the thread OPEN (08-reply-and-resolve.ps1 -NoResolve) so the human merge owner can act on it. See 08-reply-resolve.md.
• Copilot threads are loop-owned; human / advanced-security / other-bot threads default to escalate-to-user. Auto-resolving a human review thread can hide unaddressed concerns. See 04-triage.md for the rubric.
• One focused commit per round, not one per PR. Bundling rounds destroys the audit trail of which finding drove which change and breaks git bisect. See 07-commit-push.md.
• Build/test/lint with the repo's own commands (per its CONTRIBUTING / AGENTS / README / package.json / Makefile) before pushing a fix. Discovery procedure: 06-build-test.md.
• Push back with written rationale when a Copilot finding would over-engineer the design for a hypothetical edge case. Auto-accepting every suggestion erodes the design — see the decline path in 04-triage.md.
• Scripting traps (gh api graphql -F type-coercion, git stash push -m positional parsing, the three GraphQL traps for the reviewer mutation) are documented in references/api-quirks.md. Read before modifying any script.

Troubleshooting

Issue	Solution
Script throws prerequisite missing — gh CLI is not on PATH	Install gh (winget install GitHub.cli on Windows; brew install gh on macOS; package manager on Linux; or download from https://cli.github.com). Then gh auth login. Surface the message to the user and STOP the loop — do not retry.
Script throws prerequisite missing — gh CLI is not authenticated	Run gh auth login. STOP the loop until the user completes auth.
Trigger fails or no copilot_work_started event lands	Push a substantive (non-whitespace) commit — auto-assign on synchronize is the most reliable trigger. Persistent failure indicates Copilot Code Review may not be enabled on the repo / account (check repo Settings → Code & automation → Copilot, or account-level Copilot Pro/Pro+).
No new review after waiting ~10 min	Quiet-period after recent dismissal or trivial-diff suppression. Push a substantive commit and retry. Do not blindly re-run 01-request-review.ps1 — it reports InFlight while Copilot is still a requested reviewer.
Outdated-but-unresolved threads in the open list	Expected: unresolved state is the source of truth. Reply + resolve them like any other open thread. 10-cleanup-outdated.ps1 is only a final safety net.
Unsure whether to fix or decline a finding	See references/04-triage.md.
Need a reply phrasing for "fixed", "declined", or "drift"	See the templates under templates/ — reply-fix.md, reply-decline.md, reply-drift.md, reply-partial.md.
