Add copilot-pr-autopilot skill (#1944)

* Add copilot-pr-autopilot skill

Skill that drives any GitHub pull request through repeated rounds of
Copilot Code Review until the agent has either resolved every thread
or explicitly escalated it to the human. Triggered via GraphQL (no
@copilot mention needed), triages every open thread with a fix /
decline / escalate rubric, replies and resolves each thread citing
the pushed SHA, then re-triggers until HEAD is reviewed with zero
threads awaiting the agent's reply.

Includes step scripts (01 request-review, 02 check-review-status,
03 list-open-threads, 08 reply-and-resolve, 10 cleanup-outdated),
shared library (_lib.ps1) with gh-CLI wrappers (Invoke-Gh,
Invoke-GhGraphQL, ConvertFrom-GhJson, Assert-GhReady), reply
templates, and reference docs for each step.

Repo-agnostic. Requires gh CLI on PATH and repo Triage/Write for
full autopilot; external PR authors get single-iteration mode with
manual re-trigger via the UI re-request button or a substantive
push.

* Address review: split per-step references + add recap-gate circuit breaker

- Fix #1: give steps 1/7/10 their own reference files
  (01-request-review.md, 07-commit-push.md, 10-cleanup.md); trim the
  inline bodies out of orchestration.md so it stays cross-cutting only.
- Fix #3: add a recurring round-cap & recap gate to 09-convergence.md —
  default STOP every 10th round, recap all prior rounds, detect drift
  (out-of-scope / over-engineering / wrong-direction / belongs-in-separate-PR)
  with CONTINUE / REVERT-AND-SHIP / HAND-OFF verdicts. Agent reasoning,
  no new script.
- Surface the gate from SKILL.md and orchestration.md; regenerate
  docs/README.skills.md. Markdown-only change; scripts unchanged.

* docs(copilot-pr-autopilot): surface recap gate in decision pseudo-code; clarify Copilot+human convergence and round definition

- Inject the round-cap recap gate into the '## Decision: loop back or exit'
  pseudo-code else-branch so an agent following the code block (not just the
  prose) runs the STOP-every-10th-round check before looping.
- Broaden the 'never terminal' paragraph: non-convergence is driven by a
  Copilot finding OR a human review comment (this skill handles both); the
  loop ends only when there are no new comments from either source AND every
  open thread (Copilot or human) has an agent reply/escalation.
- Define a 'round' explicitly as one execution of step 1 (01-request-review),
  i.e. one Copilot-review trigger — the cap counts review rounds, not tool
  calls or fix edits.

Markdown-only; no script changes.

* copilot-pr-autopilot: make recap-gate round count deterministic

Add 09-review-round.ps1: counts Copilot Code Review submissions straight
from the PR's API history (full GraphQL pagination), so the recap-gate
trigger is a derived number, not a fallible agent mental tally. This
removes the exact failure mode the skill exists to survive — a count
drifting across a long run (the real 156-round case).

The script reports Round + RecapDue (Round % RecapInterval == 0) only;
it never stops the loop or picks the verdict. CONTINUE / REVERT-AND-SHIP
/ HAND-OFF stays agent reasoning. 09-convergence.md updated to reference
the deterministic count while preserving 'no script stops the loop' and
'non-convergence = Copilot finding OR human comment'.

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). | `references/01-request-review.md`<br />`references/02-wait.md`<br />`references/03-list-threads.md`<br />`references/04-triage.md`<br />`references/05-fix.md`<br />`references/06-build-test.md`<br />`references/07-commit-push.md`<br />`references/08-reply-resolve.md`<br />`references/09-convergence.md`<br />`references/10-cleanup.md`<br />`references/api-quirks.md`<br />`references/orchestration.md`<br />`scripts/01-request-review.ps1`<br />`scripts/02-check-review-status.ps1`<br />`scripts/03-list-open-threads.ps1`<br />`scripts/08-reply-and-resolve.ps1`<br />`scripts/09-review-round.ps1`<br />`scripts/10-cleanup-outdated.ps1`<br />`scripts/_lib.ps1`<br />`templates` |
