jackin-create-pr

Open a PR for a small fix in the jackin❯ repo — typo, dependency bump, one-line bugfix, doc tweak — that needs no roadmap item. Also the shared PR-mechanics path other skills reuse. Commits inline; no separate commit skill.

jackin❯ rule files auto-load — PULL_REQUESTS.md, .github/ agent rules, BRANCHING.md, COMMITS.md. This skill sequences them, never restates them. Read them for full rules.

When to use

• Operator runs jackin-create-pr.
• Small, self-contained change (no design, no roadmap item).

When NOT to use

• Feature/idea worth a roadmap item → jackin-propose.
• Implementing a finalized roadmap item → /goal Implement <slug>.md.

Arguments

• --branch <name> — explicit branch name.
• --auto-branch — pick the branch name yourself, no confirmation.
• --title <msg> — commit + PR title (else derive from the diff, Conventional Commits).

Process

1. Branch. Never commit to main. If on main, create a fix/ / chore/ / docs/ / refactor/-prefixed branch named from the change. Suggest and confirm unless --auto-branch or --branch given.
2. Commit. Uncommitted changes → commit inline per COMMITS.md: Conventional Commits subject, DCO sign-off (git commit -s). Already committed → skip. Then git push.
3. Build the body. [bin] Run cargo xtask pr body --base origin/main > /tmp/pr-body.md. The classified change digest (rust / docs / capsule / schema + file list) prints to stderr — read it; the body skeleton goes to the file: the PR template (read from .github/PULLREQUESTTEMPLATE.md at runtime) with the verify-locally blocks already selected and byte-exact, prose left as placeholders. Block selection: Checkout + isolation env always; Rust tests on a Rust change; Docs checks + walk on docs/**; jackin-capsule smoke (with --capsule before any console/load) on crates/jackin-capsule/; schema migration smoke on a versioned-schema touch.
4. Fill + create. [agent] Edit /tmp/pr-body.md — write the prose sections (Summary, What ships, Behavior changes) from the digest + diff; drop the optional sections you do not need. Then gh pr create --body-file /tmp/pr-body.md. The binary already wrote the body, so there is no heredoc to quote.
5. Verify render. gh pr view <PR> --json body -q .body — confirm the prose you added renders (no stray \ or \$ from hand-editing). Fix with gh pr edit --body-file` if needed.
6. Reply. Share the PR URL and repeat the Verify-locally commands in your final message.

Common mistakes

• Committing to main instead of a branch.
• Hand-building the body or template instead of cargo xtask pr body — it reads the template and selects the verify blocks for you.
• Posting the skeleton with the prose placeholders left unfilled.
• Deployed docs URLs in the body (break post-merge) — refer to docs by name.

Tooling

cargo xtask pr body (jackin❯ repo) emits the change digest + the template skeleton with verify-locally blocks auto-selected from the diff. Shared with propose. The binary guarantees the mechanical parts (block selection, capsule ordering, exact command text, heredoc quoting); the agent writes the prose.
