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 5.1 | $0.02190 | $0.02190 |
| Opus 5 | $0.01095 | $0.01095 |
| Sonnet 5 | $0.00438 | $0.00438 |
| Haiku 4.5 | $0.00219 | $0.00219 |
Grade A, and why
agents-skills 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 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.
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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this repository is
A public, shareable collection of AI toolchains — Skills and Agents — meant to be consumed by others across multiple AI coding tools (Claude Code, GitHub Copilot, Cursor). It is a content/config repo: there is no application code, no build step, and no test runner. "Correctness" here means each artifact is valid for its target tool and works when dropped into a consumer's environment.
Because it is public and reusable, every artifact must be clean of personal and prior-project data. No employer names, internal URLs, ticket IDs, secrets, file paths from private repos, or learnings that only make sense inside one codebase. Keep learnings isolated — phrased generically so they apply anywhere.
Primary goal: extreme token savings at the highest practical accuracy. Every authored skill operates in caveman mode for terse working output, and model spend is tiered — the cheapest capable model per task, with mechanical work offloaded to a cheap-tier subagent and premium reserved for operator-gated hard reasoning. See MODEL-DEFAULTS.md.
Repository layout
Skills and Agents are the two primary artifact types. The canonical homes are the directories Claude Code auto-discovers:
.claude/skills/<skill-name>/SKILL.md— one directory per skill;SKILL.mdholds YAML frontmatter (name,description) + the skill body. Supporting files (references/, scripts) live alongside it..claude/agents/<agent-name>.md— one file per agent; frontmatter (name,description,tools, optionalmodel) + system prompt. Ships 16 tiered worker agents (scouton the cheap tier;builder,reviewer,implementer,pr-rescuer,diagnostician,verifier,spelunker,design-mapperon workhorse — these the commands dispatch — plus thepr-dispatcher,pr-comments,pr-checks,pr-cleanupsingle-lane PR watchers and theci-speed-hunter,ci-flake-huntercontinuous CI lanes and thebranch-fffast-forward lane, all run via/loop). Canonical agents live here;make sync-agentsgenerates the Cursor (.cursor/agents/,model/readonlyschema), Copilot (.github/agents/*.agent.md), Kiro (.kiro/agents/,toolscategory allowlist) and OpenCode (.opencode/agents/,mode/permission) copies — never hand-edit those. Keep agents thin and point at the relevant skill for the protocol..claude-plugin/marketplace.json+plugins/agents-skills/(Claude Code) and.cursor-plugin/marketplace.json+plugins/agents-skills-cursor/(Cursor) — this repo doubles as its own plugin marketplace for both ecosystems. Same skills in each (the Agent Skills format is identical); agents and commands come from that tool's generated mirror, since their frontmatter differs. The plugin payload is generated from.claude/{skills,agents,commands}bymake build-plugin(real copies, not symlinks — Claude Code installs the plugin dir standalone, so a link escaping it would dangle);make check-pluginfails on drift. Never hand-editplugins/. Releases are cut by.github/workflows/release-plugin.yml: CalVerYYYY.M.D.N(patch counter so same-day releases never collide), tagv<version>, assets = a full-plugin zip + one zip per skill (the latter for Claude Desktop). The workflow stamps versions — never bump them by hand..claude/settings.json— repo-level Claude Code config. Currently pinsmodel: opusandincludeCoAuthoredBy: false(commits authored without the Claude co-author trailer).
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.

agents-skills CLAUDE.md is an instructions file published in the GitHub repository skyfox675/agents-skills (10 stars, last pushed 8d ago), licensed MIT. It adds 2,190 tokens to every session, about $0.0110 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 2026-09-03.
