Prepare PR

Overview

Prepare the PR head branch for merge after /review-pr.

Inputs

• Ask for PR number or URL.
• If missing, use .local/pr-meta.env if present in the PR worktree.

Safety

• Never push to main.
• Only push to PR head with explicit --force-with-lease against known head SHA.
• Do not run git clean -fdx.
• Wrappers are cwd-agnostic; run from repo root or PR worktree.

Execution Contract

1. Run setup:

${CLAUDE_PLUGIN_ROOT}/scripts/pr-prepare init <PR>

2. Resolve findings from structured review:

• .local/review.json is mandatory.
• Resolve all BLOCKER and IMPORTANT items.

3. Commit scoped changes with concise subjects (no PR number/thanks; those belong on the final merge/squash commit).

4. Run gates via wrapper.

5. Push via wrapper (includes pre-push remote verification, one automatic lease-retry path, and post-push API propagation retry).

Optional one-shot path:

${CLAUDE_PLUGIN_ROOT}/scripts/pr-prepare run <PR>

Steps

1. Setup and artifacts

${CLAUDE_PLUGIN_ROOT}/scripts/pr-prepare init <PR>

ls -la .local/review.md .local/review.json .local/pr-meta.env .local/prep-context.env
jq . .local/review.json >/dev/null

2. Resolve required findings

List required items:

jq -r '.findings[] | select(.severity=="BLOCKER" or .severity=="IMPORTANT") | "- [\(.severity)] \(.id): \(.title) => \(.fix)"' .local/review.json

Fix all required findings. Keep scope tight.

3. Update changelog/docs (changelog is mandatory in this workflow)

jq -r '.changelog' .local/review.json
jq -r '.docs' .local/review.json

4. Commit scoped changes

Use concise, action-oriented subject lines without PR numbers/thanks. The final merge/squash commit is the only place we include PR numbers and contributor thanks.

Use explicit file list:

${CLAUDE_PLUGIN_ROOT}/scripts/committer "fix: <summary>" <file1> <file2> ...

5. Run gates

${CLAUDE_PLUGIN_ROOT}/scripts/pr-prepare gates <PR>

6. Push safely to PR head

${CLAUDE_PLUGIN_ROOT}/scripts/pr-prepare push <PR>

This push step includes:

• robust fork remote resolution from owner/name,
• pre-push remote SHA verification,
• one automatic rebase + gate rerun + retry if lease push fails,
• post-push PR-head propagation retry,
• idempotent behavior when local prep HEAD is already on the PR head,
• post-push SHA verification and .local/prep.env generation.

7. Verify handoff artifacts

ls -la .local/prep.md .local/prep.env

8. Output

• Summarize resolved findings and gate results.
• Print exactly: PR is ready for /merge-pr.

Guardrails

• Do not run gh pr merge in this skill.
• Do not delete worktree.
