Release update downstream packages

Update Downstream Packages

A release of one of the user's packages just published. Find every repo of theirs that consumes it, bump the pin (and sibling workspace packages released together with it), refresh lockfiles, commit, push to trunk, and verify CI end to end.

Arguments: $ARGUMENTS

This command pushes to trunk of many repos. Nothing is mutated before the Phase 3 confirmation gate. --no-push runs the whole procedure but leaves commits local.

---

Phase 1: Inputs and Pre-flight

1. Package — the first non-flag argument. If missing, ask.
2. Version — the second non-flag argument, or discover the latest published version from the package index (for PyPI: https://pypi.org/pypi/<package>/json; for npm: npm view <package> version). Confirm the version actually exists on the index before touching anything — locking against an unpublished version fails everywhere at once.
3. Workspace roots — from --roots globs. If not given, ask the user which directories hold their open-source checkouts (e.g. glob patterns two levels deep under a work directory). Do not assume a layout.
4. Sibling packages — if the package is developed in a workspace repo that publishes several packages versioned together, list the siblings (from the source repo's packages/* manifests or the index). They bump together.
5. Fresh resolver cache — for Python consumers, run uv cache clean --force once before any locking, so every lock resolves against the newly published files rather than a stale cached index.

Phase 2: Discover Consumers

Scan the workspace roots for repos whose manifest depends on the package:

rg -l '<package>' <root>/*/pyproject.toml <root>/*/package.json

For each hit, record:

• Worktree? If .git is a file rather than a directory, it is a linked worktree — skip it; the primary checkout will be found on its own.
• Trunk — git symbolic-ref refs/remotes/origin/HEAD, falling back to whichever of main/master exists.
• Owner — from git remote get-url origin. Group repos by owner org; the user confirms which orgs are in scope at the gate.
• Current pin(s) — the pinned version(s) of the package and any siblings in the manifest.
• Source overrides — dependency sources that shadow the index ([tool.uv.sources] entries, npm file:/link:/git: specs). These repos need the override removed and the published index package used instead — as its own commit, before the bump.
• Resolver cutoffs — for uv consumers, whether [tool.uv.exclude-newer] is set and whether the package and every sibling appear under [tool.uv.exclude-newer-package]. A missing entry blocks the fresh release at lock time; add the missing entries as their own commit, before the bump.
• Dirty? Repos with uncommitted changes get reported and skipped unless the user says otherwise.

Phase 3: Confirmation Gate (mandatory)

Present the plan before mutating anything:

• Per repo: path, owner, branch to update, current pin → new version, and any prep commits needed (source-override removal, exclude-newer-package additions).
• Skipped repos with reasons (worktree, dirty, org out of scope).
• Whether pushes will happen (--no-push inverts the default).

Ask the user to confirm scope via ask-user-choice — which owner orgs are in scope, and whether any repo needs a branch override or an additional branch beyond trunk (some projects maintain a long-lived second branch that also consumes the package; the user names it, the same per-repo procedure runs on it). Do not proceed without confirmation.

Phase 4: Per-Repo Procedure

Repos are independent — parallelize with background agents batched by owner org (up to 4 batches), or run sequentially if agents are unavailable. Each repo, on each of its confirmed branches:

1. Sync — git checkout <branch> && git pull --ff-only.

2. Prep commits (each on its own, only if discovery flagged it):

   • Remove the source override so the repo consumes the published index package. Commit it alone, e.g. py(deps[docs]) Use published <package> from PyPI with a why/what body.
   • Add missing entries to [tool.uv.exclude-newer-package] (<name> = false, alphabetical order). Commit alone; wrap exclude-newer-package in backticks in the subject: py(deps[uv]) Add <name> to `exclude-newer-package` whitelist with a why/what body noting the cooldown would otherwise block the fresh release.

3. Bump pins — replace the pinned version for the package and all siblings in the manifest. A pattern replacement across the shared version series catches every sibling at once, e.g.:

   sed -i 's/==0\.0\.1a[0-9]\+/==0.0.1a<N>/g' pyproject.toml
   

4. Re-lock — the ecosystem's lock command (uv lock, npm install --package-lock-only, ...). On a resolution failure, uv cache clean --force and retry once.

5. Prerelease warnings mean stop. If locking warns about prerelease resolution or would need --prerelease flags or config to accept the version, do not add flags, pins, or config to force it through — halt this repo and report. A correctly published release resolves without coaxing; a warning means something upstream is wrong (stale cache, missing exclude-newer-package entry, or a bad publish).

6. Commit — mirror the repo's own previous bump commits for this package (git log --oneline --grep '<package>'). Fallback subject, version-arrow form:

   py(deps[docs]) <package> <old> → <new>
   

   Body: why/what summarizing what the new release ships — read the package's CHANGES entry for the version, do not invent.

7. Push — git push (skip with --no-push). Never force.

Phase 5: Verify with gh

For every pushed repo:

1. Clear stale Actions caches so CI resolves fresh:

   gh cache delete --all --repo <owner>/<repo>
   

2. Watch the run for the pushed commit:

   gh run list --repo <owner>/<repo> --branch <branch> --limit 1
   

3. On failure: clear the cache again and gh run rerun <run-id> --failed. If it still fails, compare with the run before the bump — a pre-existing failure is reported as such, not retried forever.

4. Where the repo deploys docs from CI, confirm the docs job/workflow succeeded too — a docs-dependency bump that breaks the docs build defeats the point.

Output

1. Hero line: ✓ <package> <old> → <new> across N repos (or ⚠ with the failure count).
2. Rollout summary — per repo: branch, prep commits, bump commit, pushed or local, CI status.
3. Stopped repos — any halted on prerelease warnings, dirty trees, or persistent CI failures, each with what the user should look at.
4. Next-step ask-user-choice panel: rerun failed CI checks / retry stopped repos / push the --no-push commits / done.

Portability notes

• ask-user-choice — present the listed options and wait for the user to pick one. Hosts with a structured multiple-choice tool (Claude Code's AskUserQuestion) should use it; otherwise print a numbered list and wait for a numbered reply. Never proceed on an assumed answer.
• $ARGUMENTS — the text the user passed when invoking this skill. If your host does not substitute it, read it as the user's request in the current turn, and ask when there is none.
