In plain words
What is it for?
Use them when editing documentation, changelogs, contributing guides, or build-related files in the pm-skills-mcp project.

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

pm-skills-mcp CLAUDE.md 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 11d 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.

What it actually says

Claude Code Instructions

Project Context

  • pm-skills-mcp is a Model Context Protocol (MCP) server
  • Exposes the pm-skills library as MCP tools
  • Skills are embedded at build time from the upstream pm-skills repository
  • Apache 2.0 licensed

Documentation Rules

Public vs Private Files

  • _NOTES/ is gitignored - external readers cannot access these paths
  • Never reference _NOTES/ in public-facing files:
    • README.md
    • CHANGELOG.md
    • CONTRIBUTING.md
    • Any file a user cloning the repo would read
  • If content from _NOTES/ needs to be public, move it to a tracked location first

Skills Directory

  • skills/ is gitignored - embedded at build time, not tracked in git
  • In documentation, describe skills as "embedded at build time from pm-skills"
  • For skill content issues, direct users to the upstream pm-skills repository

CHANGELOG Best Practices

  • Describe what changed, not where your working files are
  • Reference public paths only
  • Link to GitHub issues/PRs for context, not internal planning docs

File References

When referencing files in documentation:

  • Use relative paths from repo root
  • Only reference tracked (non-gitignored) files
  • If a file is gitignored, summarize its content instead of linking

Architecture Notes

Build Process

  1. npm run embed-skills copies skills from pm-skills repo
  2. npm run build compiles TypeScript to dist/
  3. npm run prepublishOnly runs embed + build before npm publish

Key Directories

  • src/ - TypeScript source code
  • tests/ - Vitest test suite
  • dist/ - Compiled output (gitignored)
  • skills/ - Embedded skills (gitignored, populated at build)

MCP Protocol

  • Tools: 59 total (40 skill tools + 11 workflow tools + 8 utility tools)
  • Resources: Skill templates and examples (87 resources)
  • Prompts: Pre-configured skill invocations (3 prompts)
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.
