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 | $0.02766 | $0.02766 |
| Opus 5.5 | $0.01106 | $0.01106 |
| Sonnet 5.5 | $0.00553 | $0.00553 |
| Haiku 4.5 | $0.00277 | $0.00277 |
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 2d 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 — 140 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 Is
Specy is a DDD toolkit that captures business knowledge in structured DSL files (.prd, .sysreq, .domain, .arch). This repo contains the AI skill definitions, packaged as a single Claude Code plugin named specy. The 13 skills (invoked as specy:<name>) are: 7 core — prd-design, sysreq-design, sysreq-extract-from-code, domain-design, domain-build-code, domain-extract-from-code, domain-refactor — 3 architecture — architecture-design, architecture-extract-from-code, architecture-build-code — 2 synthetic data — synth-design, domain-build-fixtures — plus 1 auxiliary — domain-dialogue. Skills are assembled from modular templates into self-contained dist/skills/<name>/SKILL.md files.
Build Commands
# Build all skills (assembles src/skills/ templates → dist/)
./src/skills/build.sh
# Build a single skill
./src/skills/build.sh domain-extract-from-code
# Build tree-sitter parsers + run smoke tests against examples/
./src/tree-sitters/build.sh # requires: tree-sitter CLI
# Register the parsers in Neovim (writes ~/.config/nvim/plugin/specy-tree-sitter.lua, then checks it)
./src/tree-sitters/sync-nvim.sh
# Regenerate the PRD and SysReq metamodel diagrams (repo root specy-*-metamodel.svg)
./src/diagrams/build.sh # requires: python3 + network on first run (fonts, fontTools)
# Install the `specy` plugin (symlinks dist/ → ~/.claude/skills/specy)
./install-skills-for-user.sh
Architecture
Template Assembly System
Skills are assembled by src/skills/build.sh from modular templates:
- Each skill has a
src/skills/{skill}/main.mdtemplate - Templates use include markers that the build script resolves:
<!-- include: path -->— inlines file content as-is<!-- include-code: lang path -->— wraps in a fenced code block
- Include paths resolve first relative to the skill directory, then fall back to
src/skills/ - Output goes to
dist/skills/{skill}/SKILL.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.

skills CLAUDE.md is an instructions file published in the GitHub repository specy-ai/skills (5 stars, last pushed 2d ago), licensed MIT. It adds 2,766 tokens to every session, about $0.0111 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 2026-08-31.
