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.

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 | $0.00538 | $0.00538 |
| Opus 5 | $0.00269 | $0.00269 |
| Sonnet 5 | $0.00108 | $0.00108 |
| Haiku 4.5 | $0.00054 | $0.00054 |
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.

skilldrop CLAUDE.md is an instructions file published in the GitHub repository sananthanarayan/skilldrop (2 stars, last pushed 20d ago), licensed MIT. It adds 538 tokens to every session, about $0.0027 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
