| description | Prepare a Raycast extension release — run TypeScript, lint, test, and build checks locally, fix any errors, update CHANGELOG.md, and draft release notes. Use this skill whenever the user mentions releasing, publishing, preparing a release, cutting a version, updating the changelog, or wants to make sure their code passes CI before pushing. Also trigger when the user says "prepublish", "ship it", "release prep", or asks to check everything before merging. |
Raycast Extension Release Preparation
You are preparing a Raycast extension for release. The goal is to catch every issue that CI would catch — and fix it — before the user pushes. Then update the changelog and draft release notes.
This matters because CI failures on TypeScript errors, lint issues, or broken builds waste time and block releases. Running the same checks locally first eliminates surprises.
Step 1: Pre-release quality gate
Run these checks in this order, because each layer catches different problems and earlier fixes can resolve later failures (e.g., a lint autofix might also fix a type error):
1a. TypeScript type checking
./node_modules/.bin/tsc -p tsconfig.json --noEmit
This is the most important check. It catches type errors like null-narrowing issues with discriminated unions, missing properties, and incorrect argument types — the exact kind of errors that slip through to CI.
If there are errors: read the failing files, understand the root cause, and fix them. Common patterns in this codebase:
- Discriminated union narrowing: when using
useLanguagePair(), guard on !langResult.pair (not langResult.error) so TypeScript narrows the union properly
- Null assertions: prefer explicit null guards with early returns over
! assertions
Re-run tsc after fixes to confirm they resolve all errors.
1b. ESLint
npm run lint
If there are auto-fixable issues, run npm run fix-lint first, then re-check. For remaining manual issues, fix them individually.
1c. Tests
npm run test
If tests fail, investigate and fix. Do not skip failing tests.
1d. Build
npm run build
This runs ray build and validates the full compilation pipeline. Build failures here mean the extension won't work when published.
If any check fails: fix the issue, re-run that check, and then re-run all subsequent checks (a fix for one problem can introduce another). Only proceed to Step 2 when all four checks pass cleanly.
Step 2: Update CHANGELOG.md
The changelog lives at the project root: CHANGELOG.md. It surfaces in Raycast under the extension's Version History and on the store, so follow Raycast's convention exactly — not generic semver.
Source of truth: Raycast docs — Prepare an Extension for Store › Version History and Versioning.
Raycast changelog rules
- One h2 section per submission. Each published update gets its own
## [Title] - {PR_MERGE_DATE} heading at the top of the file (newest first).
- Title in square brackets, then
- (hyphen with a space on each side), then the date.
- Use the literal
{PR_MERGE_DATE} placeholder for the new entry — Raycast replaces it with the real merge date on merge (which can be days later, after review). Do not type today's date.
- Flat bullet points under the heading describing user-visible changes. No
### Added / Changed / Fixed / Removed subsections — Raycast doesn't use them.
- Never edit an already-published, dated section. Past entries carry a hard
YYYY-MM-DD date and are immutable history; new work always goes in a fresh {PR_MERGE_DATE} section. Slipping changes into a shipped entry buries them under the wrong date.
Example (matches the Raycast docs):
# Brew Changelog
## [Added a bunch of new feedback] - {PR_MERGE_DATE}
- Improve reliability of `outdated` command
- Add action to copy formula/cask name
## [New Additions] - 2022-12-13
- Add greedy upgrade preference
- Add `upgrade` command
Determine what's genuinely new
Raycast extensions aren't released via git tags or package.json version bumps, so don't look for those. The "since last publish" range is what's new since the store's current version:
git log "$(git tag -l '__raycast_latest_publish_ext/*' | head -1)"..HEAD --oneline
If you ran pull-contributions during this release, the most reliable diff is against the store state directly — compare CHANGELOG.md (and the tree) against the contributions parent of the merge so you only list bullets the store doesn't already have:
git diff <contributions-parent>..HEAD -- CHANGELOG.md
Guidelines:
- Each bullet describes a user-visible change, not an implementation detail.
- Group related commits into a single bullet when they're one logical change.
- Skip merge commits, CI/config changes, and internal refactors that don't affect behavior.
- After editing, run
npm run lint — ray lint validates the changelog format and accepts {PR_MERGE_DATE}.
Step 3: Draft release notes
After updating the changelog, draft concise release notes suitable for the Raycast Store submission / PR description. Use the new changelog section's title (Raycast extensions have no semver version). The format:
**What's new — [changelog section title]**
[2-3 sentence summary of the most important changes]
Highlights:
- [Key change 1]
- [Key change 2]
- [Key change 3]
Present the release notes to the user for review — don't commit them automatically.
Step 4: Summary
Present a summary to the user:
- Which checks passed / what was fixed
- The changelog diff
- The draft release notes
- Any remaining action items — for Raycast that's typically: run
npm run publish to open/update the PR in raycast/extensions, then mark the draft PR "Ready for review". (No version bumps or git tags — Raycast doesn't use them.)
Important
- Use
npm to run scripts (not bun or yarn)
- Do not push to remote or run
npm run publish without explicit user approval — publishing opens/updates a public PR in raycast/extensions
- Raycast extensions have no
package.json version to bump and no release tags to create — don't invent them
- Commit fixes from Step 1 separately from changelog updates — the user should be able to review each independently
