skilldrop CLAUDE.md

skilldrop CLAUDE.md is an instructions file for coding agents from sananthanarayan/skilldrop. It costs 538 tokens per session, scanned A, original, MIT.

Repository instructions for Claude Code, including how to use the project's skills and test them in a separate session. Claude Code is an AI coding tool that automatically reads CLAUDE.md files.

In plain words
What is it for?
Use it when developing or dogfooding a skill in the skilldrop repository with Claude Code.
Why use it?
It keeps Claude-specific setup separate from general agent guidance and explains how installed skills are found and refreshed during development.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

skilldrop 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 4d 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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

The substantive guidance for any agent working in this repo lives in AGENTS.md — repo overview, golden rules, file placement, voice & tone, and the pre-commit checklist. Read it first.

This file exists because Claude Code auto-loads CLAUDE.md. Everything below is Claude-Code-specific ergonomics that don't belong in the cross-IDE AGENTS.md.

Dogfooding a skill while you build it

The fastest feedback loop for new or edited skills:

# user-scope: skill is available in every Claude Code session, no project pollution
mkdir -p ~/.claude/skills && cp -R skills/<skill-name> ~/.claude/skills/

# then in a new Claude Code session in any repo:
/<skill-name> <args>

For changes-in-flight, recopy after each edit — Claude Code reads SKILL.md fresh per invocation, but the copy in ~/.claude/skills/ is the one it sees, not the working tree.

${CLAUDE_SKILL_DIR} semantics

Claude Code exports CLAUDE_SKILL_DIR to the absolute path of the installed skill folder when a skill runs. Use it in SKILL.md when telling the agent how to invoke a script:

Run: `python3 ${CLAUDE_SKILL_DIR}/scripts/build_deck.py <args>`
(or, in non-Claude IDEs: `python3 skills/<skill-name>/scripts/build_deck.py <args>`)

Always show both forms — ${CLAUDE_SKILL_DIR} for Claude Code, plain relative for Cursor / Continue / Cline / Aider. Hard-coding only one breaks portability, which is the whole point of skilldrop.

Project settings

.claude/settings.json exists at the repo root and is currently empty ({}). It's the canonical place to add Claude-Code-specific configuration scoped to this project — hooks, permissions allowlists, enabledPlugins, extraKnownMarketplaces, or environment overrides. Add config when you have something concrete to configure; an empty file is honest about the current state.

When NOT to use a skill

Don't invoke a skilldrop skill from inside another skilldrop skill. Skills are designed to compose at the human's invocation layer (e.g. user runs brief-intake then hands the brief to adr-generator), not via internal chaining. If two skills genuinely need to call each other, that's a signal to merge them or to extract shared logic into reference.md.

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.
