CLAUDE.md

skillet CLAUDE.md is an instructions file for Claude Code from skilletmd/skillet. It costs 2,686 tokens per session, scanned A, original, Apache-2.0.

Project guidance for Skillet, a registry and synchronisation system for agent skills. It documents repository conventions, architecture, testing rules, and build details for its pnpm-workspaces monorepo, where several packages share one codebase.

In plain words
What is it for?
Use it when developing, testing, reviewing, or troubleshooting the Skillet web app, API, command-line tool, desktop app, or shared packages.
Why use it?
It records repository-specific facts that are easy to miss, including how packages resolve during builds and which documents define project conventions.

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

skillet CLAUDE.md 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 8d 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.

CLAUDE.md

Guidance for agents (and humans) working in this repo. Conventions, setup, and commit format live in CONTRIBUTING.md; domain vocabulary in docs/CONCEPTS.md; review guidance in docs/REVIEW.md. This file holds what you'd otherwise learn the hard way.

Skillet is a registry + sync system for agent skills: publish a skill once, run it in every agent runtime. Monorepo (pnpm workspaces):

Package What it is
packages/web Next.js app (skillet.md) — profiles, kits, feed, updates
packages/registry Fastify + Prisma/MySQL API (:3481 in dev)
packages/cli skilletmd — the skillet command
packages/core Sync engine shared by CLI + desktop sidecar
packages/protocol Wire types, signatures, covers — shared by everything
packages/desktop Tauri tray app; bundles the CLI as a sidecar
packages/adapters/* Per-runtime install adapters
packages/mcp MCP server surface

Build reality (read before trusting failures)

Workspace packages resolve through gitignored dist/ directories. A fresh clone, a fresh worktree, or a rebase that touched packages/protocol or packages/core leaves stale or missing dist, which produces phantom failures: "Failed to resolve entry for package @skillet/protocol", missing-export runtime errors, or test failures unrelated to your diff.

pnpm build orders the workspace correctly, so building from the repo root is enough:

pnpm install
pnpm build

Ordering used to be unreliable: core devDepended on registry for its e2e suites, closing a core → registry → mcp → core cycle. pnpm cannot sort a cycle topologically and ran those packages concurrently, so mcp could compile before core emitted its dist. Those suites now live in @skillet/core-e2e, which nothing depends on, and the graph is acyclic — if you see a build-order failure again, check whether a new edge has re-closed the loop.

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.
