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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.00854 |
| Opus 5.5 | $0.00016 | $0.00342 |
| Sonnet 5.5 | $0.00008 | $0.00171 |
| Haiku 4.5 | $0.00004 | $0.00085 |
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 2mo 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 (0.1.0 → 0.2.0), 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"inserver/package.json"version"inextension/manifest.json(whatchrome://extensionsshows)
The
McpServerversion reported over MCP is no longer hardcoded —server/src/index.tsreadspkg.versionat startup, so it tracksserver/package.jsonautomatically. Andpnpm-lock.yamldoesn't record the workspace package's own version, so there's no lockfile step:pnpm install --frozen-lockfilestill 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(see9a1ca94,07ed42afor 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.

release is a skill published in the GitHub repository BlaiseMoses01/playback-mcp (5 stars, last pushed 23d ago), licensed MIT. It adds 41 tokens to every session and 854 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
