## Summary
- New workflow that auto-bumps the Homebrew formula in
[ComposioHQ/homebrew-tap](https://github.com/ComposioHQ/homebrew-tap)
whenever a stable CLI release is published.
- Triggers on `release: published` for tags matching `@composio/cli@*`.
Skips beta/rc/alpha tags. Also exposes `workflow_dispatch` for manual
replay.
- Pulls SHA256s from the release's `checksums.txt`, edits
`Formula/composio.rb` in the tap repo, and commits/pushes (no-op if
already current).
## Setup required before this can run
- Create a fine-grained PAT scoped to `ComposioHQ/homebrew-tap` only,
with `Contents: read/write`.
- Add it as a repo secret named `HOMEBREW_TAP_TOKEN` in this repo.
Without that secret the checkout step will fail; the workflow won't
break anything else.
## Test plan
- [ ] Land this PR
- [ ] Add `HOMEBREW_TAP_TOKEN` secret
- [ ] Manually run via `workflow_dispatch` with tag
`@composio/cli@0.2.28` — should be a no-op (formula already at 0.2.28)
- [ ] Verify next CLI release auto-bumps the formula

## Summary
Permanently stops the recurring *"release published with zero assets →
install/upgrade 404s"* outage
(https://github.com/ComposioHQ/composio/issues/3408,
https://github.com/ComposioHQ/composio/issues/3269; regressions of
https://github.com/ComposioHQ/composio/issues/2625 and
https://github.com/ComposioHQ/composio/issues/1820 — 3 of the last 5
stable releases shipped empty).
**Root cause:** a concurrent-writer race. On a CLI version bump,
`changesets/action` creates an empty `@composio/cli@x.y.z` GitHub
Release in seconds, then the slower `build-cli-binaries.yml` fails its
`gh release create` because the release already exists — so binaries
never attach.
> 🥞 **Stacked on #3415** (`pi/exclude-cli-ts-release-42161920`), which
removes the *second writer* (changesets no longer creates CLI releases).
Review/merge #3415 first; this PR targets that branch. This PR hardens
the now-sole writer so a *partial* build can't publish either, and fixes
the monitoring that hid the failure.
## What changed (`build-cli-binaries.yml` + canary)
- **Draft → verify → publish.** The release is built as a **draft**,
then a gate asserts all 6 canonical assets are present **and** `state ==
"uploaded"` (loud `::error::` + fail otherwise), and only the final step
flips it to published. Drafts fire no `release: published` event and are
excluded from `/releases/latest`, so no install.sh / Homebrew / redirect
consumer can observe an incomplete release.
- **`fail-fast: false`** on the build matrix → a single platform failure
can never publish a partial set (`needs.build.result` is `success` only
if all legs pass).
- **Per-tag job-level `concurrency`** so re-runs / quick pushes can't
interleave uploads on the same tag, without serializing unrelated betas.
- **Beta-safe:** `--prerelease` is set on the draft so betas stay
prereleases through the publish flip.
- **`promote-stable` guard** uses `gh release view --json isDraft` (the
REST tags endpoint 404s on drafts) to resume an existing draft but
refuse an already-published tag.
- **Least privilege:** workflow defaults to `contents: read`; only the
release job opts up to `contents: write`.
- **Canary fix** (`cli.install-health-check.yml`): install the newest
stable **pinned** tag (`npm view @composio/cli version`) instead of the
asset-aware no-arg flow, which self-heals to the last good release and
kept the canary green through every outage.
## Idempotency note
Re-running a run that failed **before publish** is safe (reuse draft +
`--clobber`). An already-**published** tag is refused, not mutated — by
design.
## Testing
- Extended `test/release-workflow.test.ts` (run via `pnpm
test:release-workflow`) to lock in: draft→verify→publish ordering,
`fail-fast: false`, per-tag concurrency, preserved `--prerelease`, and
the pinned-tag canary. ✅ passes.
- `shellcheck` clean on the new `run:` scripts; YAML validated.
`actionlint` runs in CI.
- Runtime verification of the full green path happens on the next
release CI run.
## Out of scope (deferred to their own PRs)
Per reviewer consensus, these are real but *not this bug*: a per-release
npm↔GitHub asset auditor (needs a grace window), the Homebrew trigger
constraint (folds into #3355), `composio upgrade` missing-asset back-off
(https://github.com/ComposioHQ/composio/issues/3269), and a rollback
runbook.
