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 | $0.01950 | $0.01950 |
| Opus 5.5 | $0.00780 | $0.00780 |
| Sonnet 5.5 | $0.00390 | $0.00390 |
| Haiku 4.5 | $0.00195 | $0.00195 |
Grade A, and why
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 22d 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 — 128 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.
Overview
This repository is a public collection of Claude Code skills and agents for software
development workflows. There is no application to build: skills are Markdown (SKILL.md)
with optional Bun/TypeScript helper scripts, and agents are single Markdown files.
For how Claude Code auto-loads skills, agents, rules, and memory, see
.claude/references/claude-code-loading.md.
Repository structure
skills/ # one directory per published skill, each with a SKILL.md (plus optional scripts/ and references/)
agents/ # one Markdown file per agent
plugins/ # optional plugins beside the root one (e.g. to-code: a Claude Code mod plus a pi extension)
.claude-plugin/ # plugin.json and marketplace.json, so the repo installs as a Claude Code plugin
.claude/skills/ # skills internal to this repo, not published (e.g. writing-skills-update)
.claude/references/ # shared reference docs for authoring in this repo, plus pinned dependency submodules
.claude/rules/ # path-scoped authoring conventions for this repo
package.json # Bun workspace root (workspaces: ["skills/*", "plugins/*"])
justfile # symlink management for installing agents/ into ~/.claude/agents/
Skills under skills/ are the published collection and belong in the README.md
table. Skills under .claude/skills/ are repo-internal tooling: they load
automatically when working in this repository and are not listed in README.md.
Path-scoped rules
Conformance rules live in .claude/rules/ and auto-activate via paths: frontmatter when
Claude edits matching files:
| Rule | Scope | Purpose |
|---|---|---|
skills.md |
skills/** |
SKILL.md format, Bun/TypeScript scripts, directory structure |
agents.md |
agents/**/*.md |
Agent frontmatter fields, reload behavior, validation |
plugins.md |
plugins/** |
Shared mod/pi core, adapters, the two test runners |
testing.md |
All files | Positive, exact test expectations instead of negated chains |
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.
