playback-mcp: Skill for Claude Code

.claude/skills/release/SKILL.md

release is a skill for Claude Code from BlaiseMoses01/playback-mcp. It costs 41 tokens per session (854 once invoked), scanned A, original, MIT.

A release procedure for playback-mcp, a project published partly as an npm package and partly as a browser-extension archive. It defines how to change the version, update the changelog, merge the release, create a GitHub Release, and publish through CI.

In plain words
What is it for?
Use it when preparing a playback-mcp version: choose a semantic version, update the required package and extension files, merge the changes, tag or publish a GitHub Release, and trigger npm publication through the documented workflow.
Why use it?
It removes guesswork from releasing and helps keep the server package and browser extension on the same version. CI, or automated checks and publishing, performs the final publication after the release is created.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Releasing playback-mcp

Only server/ is published to npm (as playback-mcp); the extension is built and attached to the GitHub Release as a zip. .github/workflows/publish.yml does the actual publishing — it triggers on a published GitHub Release and expects the version to already be bumped and merged into main beforehand.

Full narrative version of this lives in CONTRIBUTING.md's "Releasing" section — keep both in sync if the process changes.

1. Pick the version

Semver. This project is pre-1.0, so treat it like 0.y.z: backwards-compatible additions bump the minor (0.1.00.2.0), fixes bump the patch.

2. Prep the release commit on dev

  • Bump the version in the two places it's declared (grep the old version string to confirm none were missed):

    • "version" in server/package.json
    • "version" in extension/manifest.json (what chrome://extensions shows)

    The McpServer version reported over MCP is no longer hardcoded — server/src/index.ts reads pkg.version at startup, so it tracks server/package.json automatically. And pnpm-lock.yaml doesn't record the workspace package's own version, so there's no lockfile step: pnpm install --frozen-lockfile still passes after a bump.

  • In CHANGELOG.md: rename ## [Unreleased] to ## [X.Y.Z] - YYYY-MM-DD, add a fresh empty ## [Unreleased] above it, and update the link refs at the bottom:

    [Unreleased]: https://github.com/BlaiseMoses01/playback-mcp/compare/vX.Y.Z...HEAD
    [X.Y.Z]: https://github.com/BlaiseMoses01/playback-mcp/releases/tag/vX.Y.Z
    
  • Run the full gate: pnpm run lint && pnpm run format:check && pnpm run typecheck && pnpm run build && pnpm test.

  • Commit as release: playback-mcp vX.Y.Z (see 9a1ca94, 07ed42a for precedent).

  • git push origin dev.

3. PR dev into main

Use the pr skill. Wait for CI to go green, confirm with the user, then merge with gh pr merge <number> --merge.

4. Tag and publish

From main, after the merge:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
