What:

Pushing a v* tag now ships a release. release.yml runs the tests on macos-latest, checks that cli/package.json matches the tag, compiles arm64 and Intel binaries, smoke tests both, attaches the tarballs and checksums.txt to a GitHub Release, and pushes a rendered Formula/ski.rb to osrim/homebrew-tap. A tag containing - becomes a prerelease and skips the tap. A rerun of an existing tag skips the tap commit when the formula is unchanged.

  • cli/scripts/brew-formula.ts renders the formula from checksums.txt. It picks the URL with if Hardware::CPU.arm? because brew style rejects url inside on_arm and on_intel.
  • update-check.ts reads the latest GitHub release instead of the npm registry. The notice says brew upgrade osrim/tap/ski.
  • cli/package.json is private, has a build script, and lints scripts/. dist/ is ignored.
  • docs/releasing.md covers the version scheme, bunx bumpp, a local formula check with a fake checksums.txt, and the failure playbook, including re-tagging by hand after a fix. Linked from CONTRIBUTING. npm wording is gone from the other docs.

Why:

First public release. Users run brew install osrim/tap/ski and need git, not Bun. The tap repo and the TAP_DEPLOY_KEY secret exist. Nothing publishes until a tag is pushed.

Tested how:

  • typecheck, lint, fmt:check, and 315 tests pass.
  • bun run build && ./dist/ski --version prints ski/0.0.0 darwin-arm64 bun-v1.3.14. The Intel binary runs under Rosetta and prints darwin-x64.
  • A formula rendered from a real checksums.txt passes brew style.
  • actionlint passes on release.yml.
  • Not verified: the update notice itself. The GitHub API returns 404 until the first release exists.

  • I understand every line in this PR and followed the AI rules.

Review Change Stack

📝 Walkthrough

Walkthrough

The project now releases macOS arm64 and x64 binaries through GitHub Releases and Homebrew. Update checks use the GitHub Releases API. The repository includes formula generation, automated publishing, package configuration, tests, and release documentation.

Changes

Release distribution migration

Layer / File(s) Summary
Package build and Homebrew formula
cli/package.json, cli/.gitignore, cli/tsconfig.json, cli/scripts/*
The CLI package is private, compiles with Bun, includes release scripts in linting and TypeScript scope, and renders architecture-specific Homebrew formulas from validated checksums.
GitHub release update checks
cli/src/core/update-check.*, docs/configuration.md, docs/contributor/architecture.md
Update checks read the latest GitHub release, remove a leading v from tag_name, and show the Homebrew upgrade command. Tests and documentation reflect the new API.
Automated release publication
.github/workflows/release.yml
The workflow selects a tag, validates the package version, builds and smoke-tests arm64 and x64 binaries, publishes GitHub Release assets, and updates the stable Homebrew tap.
Release guidance and repository configuration
CONTEXT.md, CONTRIBUTING.md, docs/releasing.md, docs/contributor/standards.md
The documentation describes the GitHub Release and Homebrew process, supported architectures, recovery steps, testing guidance, and generated-output rules.

Merge Risk: 🔵 Low · up to 92af6

The release migration publishes macOS binaries and Homebrew formulas, but update guidance can point archive users to a different installation and recovery documentation can recreate a release from an old commit. These are bounded release-process risks that should be corrected before the next release.

In @.github/workflows/release.yml:
- Line 97: Update the release workflow step around the tap commit so it checks
git’s staged diff with git diff --cached --quiet before committing or pushing.
Skip both operations when the rendered formula is unchanged, while preserving
the existing commit and push behavior when staged changes exist.

In `@cli/src/core/update-check.ts`:
- Line 60: Update the update-message logic around the version-check return to
distinguish Homebrew installations from archive-installed binaries: keep the
Homebrew upgrade command only for Homebrew users, and provide a GitHub Releases
update instruction for non-Homebrew installs.

In `@CONTEXT.md`:
- Line 107: Update the release definition in the table to clarify that the
Homebrew formula is produced only for stable releases, or explicitly distinguish
prerelease output from stable-release output while preserving the existing
GitHub Release behavior.

In `@docs/releasing.md`:
- Line 3: Update the release description sentence near the start of the document
to state that releases include two macOS binaries, reflecting the arm64 and x64
tarballs uploaded by the release process.
- Line 39: Update the release instructions around the brew-formula command so
the local procedure first generates the required packaging artifact and
dist/checksums.txt with shasum -a 256 for both architectures, or explicitly
state that the command depends on release workflow artifacts. Ensure the
documented sequence matches the inputs read by brew-formula.ts.
- Line 54: Update the recovery instructions in the release documentation to
explicitly run bumpp with the existing version from cli/package.json as its
positional argument, preserving the exact X.Y.Z version instead of relying on
interactive selection.

Local check of steps 3 and 5. The formula script only needs a `checksums.txt`, so a fake one is enough:

```sh
bun run build && ./dist/ski --version

State the architecture coverage of this local check.

bun run build && ./dist/ski --version checks only the default local target. The release workflow builds and smoke-tests both arm64 and x64-baseline. Add commands for both targets, or state that this check covers only the local target. Otherwise, a maintainer can miss an architecture-specific release failure.

Create the replacement tag from updated main.

This command tags the current local HEAD. Merging the fix on remote main does not update a stale checkout, so the old broken commit can be released again. Fetch origin/main and tag that commit explicitly.

Proposed fix
-  git tag vX.Y.Z && git push origin vX.Y.Z
+  git fetch origin main
+  git tag vX.Y.Z origin/main
+  git push origin vX.Y.Z

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
git tag vX.Y.Z && git push origin vX.Y.Z
git fetch origin main
