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 | $0.00635 | $0.00635 |
| Opus 5 | $0.00318 | $0.00318 |
| Sonnet 5 | $0.00127 | $0.00127 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
learn-agent-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 9d 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 — 45 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 hands-on tutorial series for building agent skills — reusable instruction sets that teach AI coding agents (GitHub Copilot, Claude Code, Cursor, etc.) how to perform specific tasks. Learners follow 7 sequential tutorials to build a "README Wizard" skill that generates polished README files for any project.
This is a documentation-only repository — no application code, no build system, no test framework. Content is Markdown tutorials and Bash scripts.
Repository Structure
- Tutorials (
01_*.mdthrough07_*.md): Sequential lessons meant to be followed in order. Each contains prompts for learners to paste into their AI agent. .agents/skills/: Contains finished reference implementations of skills built in the tutorials (Copilot/cross-agent path)..agents/skills/readme-wizard/: The main skill built across Tutorials 3-6, with sub-folders forscripts/,references/,assets/, andevals/.assets/: Images used within the tutorial Markdown files.readme-wizard-workspace/: Gitignored directory for skill optimization/eval artifacts.
Key Conventions
- Skill folder structure follows the Agent Skills open standard:
SKILL.md(instructions + YAML frontmatter),scripts/(deterministic shell work),references/(domain knowledge),assets/(data/templates),evals/(test cases). - SKILL.md frontmatter: YAML between
---markers withnameanddescriptionfields. The folder name must match thename:field exactly. - Claude Code users use
.claude/skills/instead of.agents/skills/— this distinction is noted throughout the tutorials. - Shell scripts (
scan_project.sh) must be executable (chmod +x). - Commit messages use conventional-style prefixes (e.g.,
refactor:,fix:).
Running the Scripts
Scan a project for metadata (outputs JSON):
bash .agents/skills/readme-wizard/scripts/scan_project.sh <project-directory>
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.

learn-agent-skills CLAUDE.md is an instructions file published in the GitHub repository debs-obrien/learn-agent-skills (48 stars, last pushed 5mo ago), licensed MIT. It adds 635 tokens to every session, about $0.0032 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 2026-08-30.
