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 | $0.02644 | $0.02644 |
| Opus 5.5 | $0.01058 | $0.01058 |
| Sonnet 5.5 | $0.00529 | $0.00529 |
| Haiku 4.5 | $0.00264 | $0.00264 |
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 today.
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 — 111 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.
Repository purpose
A cdd-first methodology: continuously-discovered development as the core discipline, AI coding skills as the distribution vehicle. This repository is the home of that methodology and the vehicle that distributes it — the CDD (continuously-discovered development) practice encoded as skills and driven by the cdd engine, released as installable plugins consumable across multiple AI coding harnesses (verified on Claude Code and Pi).
kairos ships here as a first-party plugin in-tree at packages/kairos/ (kairos orchestration + cdd-* family + the CDD engine). Superpowers and mattpocock-skills are upstream third-party plugins — install them via their official commands (marked Upstream in the README); this repo no longer vendors them. Upstream workflow skills are read by kairos orchestrators via /-prefixed plugin:skill references.
⚠️ emit products are derived — never edit them
.claude-plugin/, marketplace/, and .github/ISSUE_TEMPLATE/ products are generated by pnpm run emit. After editing any file under skills/*/SKILL.md, skills/*/docs/*.md, docs/*.md, or package.json#oscaner, you MUST run pnpm run emit to regenerate them. Editing emit products directly is always wrong — your changes will be overwritten on the next emit. pnpm run emit:check verifies the products are fresh (no drift, exit 1 if stale). If CI fails with "emit drift", the fix is pnpm run emit + commit the regenerated files. This is the most common mistake in this repo.
Key commands
pnpm run emit # regenerate all harness manifests from package.json
pnpm run emit:check # verify emit output is fresh (no drift, exit 1 if stale)
pnpm run validate # full validation suite (emit check + plugin resolution + tests + Contract Lexicon wording + version sync)
pnpm run changeset # create a changeset for versioning
pnpm exec changeset version # apply changesets to bump versions + CHANGELOGs (native; CI runs it on the Version PR)
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.

skills CLAUDE.md is an instructions file published in the GitHub repository Oscaner/skills (63 stars, last pushed yesterday), licensed MIT. It adds 2,644 tokens to every session, about $0.0106 per session on Opus 5.5. 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 2026-08-30.
