fabricjs-open-pr	Use when opening a Fabric.js pull request. Generates a conventional-commit style PR title, writes a concise PR description, includes `close

Fabric.js Open PR

Use this skill when the user asks to open a PR for fabricjs/fabric.js.

Inputs

Collect or infer:

• Branch to open
• Base branch (default master)
• Issue number to close (optional)
• Short summary of changes (for title/description)

Issue-number handling:

• If the thread already includes an issue number, reuse it and do not ask again.
• If the user explicitly says there is no issue, do not ask for one and omit issue-closing text.
• Otherwise, ask the user for the issue number before creating the PR body.

Title Rules

Create a short meaningful title using conventional commits style:

• Format: <type>(<optional-scope>): <summary>
• Allowed common types: feat, fix, docs, ci, test, refactor, chore
• Keep summary short and specific.
• Use lowercase type and scope.

Examples:

• ci(): fix coverage artifact download in comment workflow
• fix(coverage): flatten playwright istanbul output
• docs(changelog): align next entry format

Required PR Body

PR body must include:

• One short description paragraph of what changed and why
• A compact bullet list of key changes
• Closing reference exactly close #<issue-num> only when an issue number is provided

Changelog Update (Mandatory)

Before opening the PR, ensure CHANGELOG.md under ## [next] contains one line in this style:

- <pr title> [#<predictedPrNum>](https://github.com/fabricjs/fabric.js/pull/<predictedPrNum>)

Rules:

• Use the exact PR title text.
• Insert near the top of the [next] list.
• Keep existing formatting untouched.

Predict Next PR Number Before Opening

From repo root, determine next issue/PR number:

latest_num=$(gh api repos/fabricjs/fabric.js/issues --paginate -F per_page=1 -F state=all --jq '.[0].number' | head -n1)
predicted_pr_num=$((latest_num + 1))

Preferred faster command (usually enough):

latest_num=$(gh api repos/fabricjs/fabric.js/issues?state=all\&per_page=1 --jq '.[0].number')
predicted_pr_num=$((latest_num + 1))

Use predicted_pr_num in the changelog line before creating PR.

Open PR Workflow

1. Confirm branch has intended commits.
2. Build PR title using conventional-commit style.
3. Resolve issue reference from thread context using the issue-number handling rules above.
4. If an issue number is provided, include close #<issue-num> in PR body; otherwise do not include issue-closing text.
5. Before any commit or PR creation, run quality checks:

npm run lint
npm run prettier:check

6. Sync with latest master before opening the PR:

git fetch origin master
git merge origin/master

7. If merge conflicts exist, resolve them before continuing.
8. Predict next PR number.
9. Update CHANGELOG.md [next] line with predicted number and title.
10. Commit and push changelog/title-related edits. Never use --no-verify; pre-commit hooks must run and pass.
11. If hooks modify files or fail, stage fixes and recommit until hooks pass.
12. Create PR with gh pr create --base <base> --head <branch> --title "<title>" --body-file <file>.
13. Fetch actual PR number.
14. If actual number differs from prediction:
    • Update the changelog line to actual number/link.
    • Commit and push the correction.
    • Optionally update PR body with a short note if needed.

Existing PR Maintenance

If the user asks to finish or unblock an existing Fabric.js PR:

1. Fetch fresh origin/master.
2. If the PR is behind base or blocked by merge conflicts, merge origin/master into the PR branch locally.
3. If the conflict involves only CHANGELOG.md, resolve it locally as part of the merge instead of asking the user whether to do that.
4. Push the merge commit to the PR branch.
5. Only pause to ask the user if the conflict touches files beyond CHANGELOG.md or if the resolution is ambiguous.

Verification Checklist

Before finishing, verify:

• PR title follows conventional commit style and matches changelog text.
• PR body includes description.
• If an issue number is provided, PR body includes close #<issue-num>.
• npm run lint passes.
• npm run prettier:check passes.
• Any commit made for this PR was created without --no-verify and pre-commit hooks passed.
• Branch was synced with latest master before PR creation.
• When maintaining an existing PR, origin/master was merged into the PR branch if that was enough to clear a CHANGELOG.md-only conflict.
• CHANGELOG.md has exactly one new [next] line for this PR.
• Link uses https://github.com/fabricjs/fabric.js/pull/<prNum>.
• If prediction mismatched, changelog has been corrected and pushed.
