release

release is a skill for Claude Code, Codex from WebMCP-org/npm-packages. It costs 79 tokens per session (3,032 once invoked), scanned A, original, MIT.

Release instructions for publishing packages from the @mcp-b monorepo, a repository that contains multiple related packages. It uses changesets to record package updates and generate changelog entries.

In plain words
What is it for?
It guides validation, changeset creation, version releases, authentication, package builds, and publishing with pnpm.
Why use it?
It helps prevent incomplete releases, incorrect dependency order, missing changelog records, and publishing unverified code.

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 1 finding 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 5d 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.

Release Skill for @mcp-b Packages

Publish packages from this monorepo to npm using changesets and pnpm publish -r.

Read references/publishing.md for package-specific build, authentication, MCPB, and troubleshooting notes.

CRITICAL: Always Use Changesets

NEVER manually edit package.json versions. Manual bumps skip CHANGELOG generation, which means published versions have no record of what changed. This has happened before and must not happen again.

The ONLY exception is snapshot prereleases (see below), whose versions are never committed.

Release Flow (Step by Step)

Follow these steps in order. Do not skip steps.

Step 1: Validate

pnpm build && pnpm typecheck && vp check && pnpm test:unit && pnpm release:check

Stop if anything fails. Fix it first.

Step 2: Create Changeset

pnpm changeset

This is interactive. It will ask:

  1. Which packages changed? Select only the ones with actual code changes.
  2. What kind of bump? (patch / minor / major)
  3. Summary of changes? Write a clear description.

This creates a .changeset/<random-name>.md file. You can create multiple changesets for different changes before releasing.

Use separate changesets when packages need different release notes. A multi-package changeset copies the same summary into every selected package's changelog.

Fixed versioning note: Select only packages that actually changed. Changesets automatically bumps all packages in the configured fixed group to the same new version, which is now every published package.

Step 3: Apply Version Bumps

pnpm changeset:version

This does four things:

  1. Bumps each selected package and every package in its fixed group
  2. Generates CHANGELOG.md entries from the changeset summaries
  3. Deletes the consumed .changeset/*.md files
  4. Synchronizes checked-in release metadata with the package versions

Step 4: Review

# Check version bumps
git diff packages/*/package.json

# Check generated changelogs
git diff packages/*/CHANGELOG.md

# Check synchronized metadata
git diff packages/webmcp-local-relay/manifest.json packages/global/test-unpkg.html

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
