description	Write PR descriptions and release notes for the Sanity monorepo. Follows the repo's PR template with Description, What to review, Testing, and Notes for release sections. Auto-triggers when creating PRs via `gh pr create`. Use when creating pull requests, writing PR descriptions, drafting release notes, or when user mentions PR, pull request, or release notes.

PR Description & Release Notes

When creating a PR

Follow the repo's PR template. Always create PRs as drafts.

1. Analyze the changes

Before writing, understand the full diff:

git log main..HEAD --oneline
git diff main...HEAD

2. PR title

Must follow conventional commits (CI-enforced):

type(scope): lowercase description

• Types: feat, fix, chore, docs, refactor, test, perf, ci
• Scope: package or area affected (groq, cli, form, schema, deps, etc.)
• No backticks, quotes, or markdown in the title
• Description starts lowercase

3. Write the PR body

Lead with why. Only elaborate on the non-obvious. The reviewer can read the diff — they need the context the diff can't give them. Default to terse; expand only where a reader would genuinely wonder.

Priorities for the Description section:

• Heavy on why — the motivation, the problem being solved, the constraint or incident that forced this change
• Cover why not — alternatives considered and rejected, one sentence each. This is often the most valuable part: it prevents the reviewer from suggesting a path you've already ruled out. Skip if there were no real alternatives worth mentioning
• Light on how — only call out approach when it's non-obvious, novel, or a reviewer might reasonably have picked a different path. Skip it for routine changes where the diff speaks for itself
• Minimal what — the diff shows what changed. One sentence of orientation at most; don't restate file-by-file changes the reviewer can see

Length test: if a sentence would tell the reviewer something they could deduce in 10 seconds from the diff, cut it. A good PR description is often 3–5 sentences total. Bulleted lists of "alternatives considered" should be one line per alternative, not a paragraph.

If you catch yourself writing "this PR renames X to Y" or "adds a new function Z", delete it. If you're explaining why X needed to be renamed or why Z exists (and why the obvious alternative wasn't chosen), keep it — but stay brief.

Use all four sections:

Description

Focus on why and why not, tersely:

• The problem or context the diff doesn't reveal (one short paragraph)
• Alternatives considered and why rejected (one line each, only if they were real candidates)
• How only when non-obvious or debatable
• What reduced to a one-line orientation

What to review

• Which files/areas matter most
• Anything tricky or non-obvious
• Which packages are affected (this is a monorepo)

Testing

• Tests added or modified
• If no automated tests: how you tested and why automation wasn't practical

Notes for release

This section is used by the docs team to write release notes.

If not needed, write one of:

• N/A — internal-only changes
• N/A – Part of feature X — partial implementation not yet enabled
• N/A – Internal only — tooling/chore work

If needed, write for end users and the docs team:

• What changed from a user perspective
• How to use it (code snippets if applicable)
• Limitations or breaking changes

4. Create the PR

Always create as draft. Do not mark as ready for review until CI passes.

gh pr create --draft --title "type(scope): description" --body "$(cat <<'EOF'
### Description

[what and why]

### What to review

[guidance for reviewers]

### Testing

[tests added or manual testing explanation]

### Notes for release

[release notes or N/A]
EOF
)"

After CI is green, mark ready for review:

gh pr ready

Release notes checklist

• Written for end users, not internal engineers
• Includes code snippets for new APIs or changed behavior
• Mentions breaking changes prominently
• No unexplained jargon
• Concise — a paragraph plus code example is ideal
