gymcoach: Skill for Claude Code

ship-pr

The shipping half of the pipeline. implement-issue opens PRs; this skill takes one open PR from "opened" to "merged", autonomously. It is the reusable unit behind the CI-watch and auto-merge loops. Read CLAUDE.md first.

Autonomy boundary (decided): auto-merge is allowed only when CI is green and the self-review is clean. The green CI is the trust boundary - never merge around it, never merge on a red or pending gate, never merge a PR a human has marked as draft or requested changes on.

Input

• A PR number, OR "ship the ready PRs" (then operate on each open, non-draft PR that targets main and is authored by the loop).

Procedure (per PR)

1. Load state and trust gate. gh pr view <n> --json number,title,headRefName,isCrossRepository,author,isDraft,mergeable,reviewDecision,state. This repo is public, so gate as an allowlist, not a blocklist, per the tiered policy in docs/loops/10-external-contributions.md (single source of truth):
   • author.login in {JulienAu, Julien-Au} and not a fork: the normal pipeline below. GitHub authorship is authenticated; the login allowlist is the real control. Do NOT gate on authorAssociation == OWNER (the loop's account is a COLLABORATOR; an OWNER check would break its autonomy).
   • Author on the vetted contributors list in that policy file (fork PRs included): auto-merge is permitted ONLY after that policy's full sequence - mechanical hard-block path gate (group B = verdict only; group A = see below), no file overlap with another PR handled this run, multi-lens adversarial review with structured verdicts, green CI on the SHA recorded before review, then the pinned merge of step 5 with --method merge (a merge commit, the default for every vetted fork PR, stacked or not). Local gate runs and fixups are permitted at this tier only.
   • Anyone else: do NOT execute their code locally (CI is the only executor - no verify.sh, no npm ci on their branch, even in a worktree). Run the read-only review of step 4 (diff as data) and post the structured verdict as a PR comment - no CI-fixing (step 3), no fixup commits. Under the operator's 2026-10-07 standing delegation, merge it on the pinned SHA (the step 5 command with --method squash) only when the same full sequence is clean - no group B path, every lens clean with no blocking/major/security finding, green CI on the recorded SHA - and the PR adds value; anything short of that, stop after the verdict, no merge.
   • Group A paths, either external tier (operator extension 2026-10-13: lib/mcp/**, lib/auth*, lib/api.ts, lib/rate-limit*, app/api/mcp-tokens/**, bulk-data routes, lib/llm/**, lib/prompts/**, Prisma schema and migrations, messages/**, i18n/**): mergeable by the loop only when, on top of the sequence above, the egress/backdoor lens and the threat-model lens both ran on those paths and are clean, and a rollback tag autonomy-baseline-<date>[suffix] is pushed at the pre-merge main before the merge call. No local run, container included, and no fixup on the contributor's branch. Group B paths (.github/**, scripts/**, .claude/**, automation/**, CLAUDE.md, docs/loops/**, container, ignore and env files, middleware.ts, dependency manifests and lockfiles, executable configs, .coderabbit.yaml): verdict only, a human merges. The lists in the policy file are authoritative. Also skip if: draft, state != OPEN, reviewDecision == CHANGES_REQUESTED, or not targeting main. Report why it was skipped.
