Instructions

Update the existing pull request for the current branch. Follow this flow:

1. Gather context: Get default branch via gh repo view --json defaultBranchRef -q .defaultBranchRef.name, then run git log --oneline, git diff --stat, and git diff against it.

2. Missing PR check: Run gh pr view --json number,url,title,body,baseRefName,headRefName,isDraft. If it fails, tell the user there is no open PR for this branch. Ask whether to switch to /create-pr or abort.

3. Uncommitted changes: If git status above shows output, ask whether to commit them, ignore them, or abort. Do not proceed until answered.

4. PR template:

   • If a template path is listed, Read it before writing title/body.
   • Detect template_language from headings/instructions/checklists (ignore code, URLs, HTML comments).
   • Keep template headings/order and keep HTML comments (<!-- -->).
   • If no template exists, skip.

5. Compose updated PR content:

   • Infer what changed since the previous PR revision from the commit log and diff.
   • Title: Conventional Commits, under 72 chars.
   • Decide title language before drafting and keep it fixed unless the user requests a change.
   • Title language policy: use template_language first whenever it can be detected.
   • If the user explicitly asks to override language for the current PR, follow that override.
   • If no template_language is detected, use: explicit user request > latest substantive user message > English.
   • Ignore slash commands (for example /update-pr), code blocks, file paths, and URLs when inferring language.
   • If language signals conflict or are ambiguous, ask the user which language to use before drafting.
   • Keep type(scope) tokens standard (feat, fix, etc.); localize only the description text.
   • Body: if template exists, fill its sections. If not, use Summary / Changes / Concerns / References.
   • Proactively include any reference links (issues, docs, related PRs) found in conversation history.

6. Confirm: Show the full updated PR title/body. Ask if the user wants to change the title, add links, or make any edits — apply and re-confirm. Do not push or edit until approved.

7. Push and update:

   • Push (git push -u origin HEAD) only if there are unpushed commits (git log @{upstream}..HEAD).
   • Update with gh pr edit --title "<title>" --body-file <file>.
   • Return the PR URL.
