Closes SB-2077

What I did

Every publish now copies the agent skills in code/lib/claude-plugin/skills/ to storybookjs/skills and tags them v<version>.

Why: #36431 makes storybook init and storybook upgrade install the skills from that repo, at the tag of the project's Storybook version. Installing from there also gives us install counts on skills.sh.

How it works

publish.yml gets two steps at the very end, after npm publish, the GitHub Release and the merges:

1. Create a token for the Storybook bot GitHub App. It can only write to storybookjs/skills and is revoked when the job ends. The app already has access to the skills repo, so nothing has to be set up before merging.
2. Run scripts/release/sync-skills.ts, which:
   • clones storybookjs/skills: next for a prerelease (11.0.0-alpha.2), main for a release (11.0.0, 11.0.1);
   • replaces skills/ with the skills from the Storybook tag v<version>;
   • commits only if something changed;
   • tags v<version> and pushes branch and tag in one atomic push.

Today the skills repo holds one hand-made commit on next, tagged v11.0.0-alpha.1, and an empty main.

Not synced: canaries, 10.6.x patches (this is not backported to main), and hand-published releases of older minors.

When it fails

The steps run last, so a failure cannot block a publish. The run turns red and Discord reports a failed publish, but npm, the GitHub Release and the merges are done.

• Don't re-run the workflow: it stops at the version bump. Run the script by hand instead; see "When the skills were not synced" in CONTRIBUTING/RELEASING.md.
• Syncing the same version twice changes nothing. This happens when you start the publish workflow by hand with skip_publish, and on the second publish run that a stable minor or major may start.
• Sync a missed version before the next publish, or skip it. Synced later, its older skills land on top of the newer ones.

Reverting this PR is safe: it only stops the sync. Tags already pushed stay.

Merge before 11.0.0

main in the skills repo is empty. The 11.0.0 publish fills it; without this PR, 11.0.0 ships with no skills to install.

After merge, watch the next prerelease publish. It is the first time the bot pushes a real commit and tag (the stories skill changed since v11.0.0-alpha.1); the CI test below only pushed a test branch.

Housekeeping: delete the SKILLS_SYNC_TOKEN secret from the Release environment. An earlier version of this PR used it; nothing references it now.

Evidence

In CI, with the real bot token: a throwaway run created the token with the same step as publish.yml, ran the sync script with it for a version the skills repo already has (so nothing changed), and pushed and deleted a test branch on storybookjs/skills.

Locally, against a copy of the real skills repo: the sequence under Manual testing below, plus these error cases:

• same version, different skills → push rejected, nothing moves
• no SKILL.md at the ref → stops before anything is committed
• unknown ref, or a version like v11.0.1 → stops with an error

Checklist for Contributors

Testing

The changes in this PR are covered in the following automated tests:

• stories
• unit tests
• integration tests
• end-to-end tests

No automated test: it is a workflow step and a small script. The scenarios under Evidence are the test.

Manual testing

Caution

This section is mandatory for all contributions. If you believe no manual test is necessary, please state so explicitly. Thanks!

No token needed: the script runs against a local copy of the skills repo.

1. Set up, from a checkout of this branch with dependencies installed:

   rm -rf /tmp/skills-remote.git /tmp/skills-check
   git clone --mirror https://github.com/storybookjs/skills /tmp/skills-remote.git
   export SKILLS_REPO_URL=file:///tmp/skills-remote.git

2. Sync v11.0.0-alpha.1 the way CI does, from the release tag. The skills repo already has this version, so expect already matches and 4db2487:

   git fetch origin tag v11.0.0-alpha.1
   VERSION=11.0.0-alpha.1 STORYBOOK_REF=v11.0.0-alpha.1 node ./scripts/release/sync-skills.ts

3. VERSION=11.0.0-alpha.2 node ./scripts/release/sync-skills.ts. Expect next is at <sha>, tagged v11.0.0-alpha.2. That is a new commit, because the stories skill changed since v11.0.0-alpha.1. Once the first real sync after merge has run, expect already matches here instead.

4. VERSION=11.0.0-alpha.3 node ./scripts/release/sync-skills.ts. Expect already matches, with the same sha.

5. Run step 4 again. Expect the same output and no error.

6. Change a skill in a scratch commit and sync that commit. Expect a new sha:

   git worktree add --detach /tmp/sb-2077-change HEAD
   echo "<!-- sync test -->" >> /tmp/sb-2077-change/code/lib/claude-plugin/skills/stories/SKILL.md
   git -C /tmp/sb-2077-change commit -qam "test: change a skill" --no-verify
   VERSION=11.0.0-alpha.4 STORYBOOK_REF=$(git -C /tmp/sb-2077-change rev-parse HEAD) node ./scripts/release/sync-skills.ts

7. VERSION=11.0.0 node ./scripts/release/sync-skills.ts. Expect main is at <sha>, tagged v11.0.0.

8. Check the result. Expect IDENTICAL, and in the log two new commits on next and one on main:

   git -C /tmp/skills-remote.git log --oneline --all --decorate --graph
   git clone --branch main file:///tmp/skills-remote.git /tmp/skills-check
   diff -r /tmp/skills-check/skills code/lib/claude-plugin/skills && echo IDENTICAL

9. Clean up: git worktree remove --force /tmp/sb-2077-change && rm -rf /tmp/skills-remote.git /tmp/skills-check.

Walkthrough

The publish workflow runs a script that copies skills from the current release tag to storybookjs/skills. The script selects the destination branch, commits only when skills change, and pushes the branch and version tag. The release guide documents automated syncing and manual recovery.

Changes

Release skills synchronization

Layer / File(s)	Summary
Skills sync and publish integration scripts/release/sync-skills.sh, .github/workflows/publish.yml	The script selects next for prerelease versions and main otherwise. It imports skills from the requested Storybook ref and exits with an error if no SKILL.md files are found. It commits only when staged skills differ, then pushes the branch and version tag. The workflow runs the script with the current version’s release tag and authenticated repository URL, including for skip_publish dispatches.
Release sync instructions CONTRIBUTING/RELEASING.md	The release guide documents branch selection, token requirements, sync failures, manual recovery, and manual syncing for emergency local releases.

Merge Risk: ⚪ Minimal · up to 9b442

The release workflow’s skills sync and manual recovery instructions match the script. No source-backed merge blocker was found; the live token setup remains an operational check.
