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 | $0.01110 | $0.01110 |
| Opus 5 | $0.00555 | $0.00555 |
| Sonnet 5 | $0.00222 | $0.00222 |
| Haiku 4.5 | $0.00111 | $0.00111 |
Grade B, and why
ai-agent-skills CLAUDE.md scanned grade B with 2 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
After installation, open `~/.claude/settings.json` (Linux/WSL) or `%USERPROFILE%\.claude\settings.json` (Windows) and add: Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
For all tasks in this repository, the conventions in AGENTS.md apply — read it first
and follow it fully (verify commands, sandbox quirk, SKILL.md rules). In case of conflict, AGENTS.md wins.
Repository Purpose
A collection of reusable AI agent skills in the open SKILL.md format. Skills are designed to be AI-agnostic — they rely only on standard tools (git, gh, shell commands) and contain no Claude-specific dependencies.
Skill Structure
Each skill lives in .claude/skills/<skill-name>/ and follows this layout:
<skill-name>/ # kebab-case folder name, must match SKILL.md `name:` field
SKILL.md # required; YAML frontmatter + Markdown instructions
references/ # optional; supporting docs loaded on demand
scripts/ # optional; executable Bash/Python helpers
assets/ # optional; templates, fonts, icons
SKILL.md Frontmatter Rules
name: kebab-case, no spaces or capitals, must match the folder namedescription: under 1024 characters, must include both WHAT the skill does and WHEN to trigger it (specific user-facing phrases); no XML angle brackets- No

Installing Skills for Claude Code
Via npm (recommended):
Installs skills, statusline.sh, and the formatter Stop hook. Enable git URL installs once:
npm config set allow-git all
Install (Linux / macOS / WSL):
npm install -g --ignore-scripts https://github.com/dboeckli/ai-agent-skills.git#master && \
bash "$(npm root -g)/@dboeckli/ai-agent-skills/scripts/install-skills.sh"
Install (Windows — PowerShell):
npm config set allow-git all
npm install -g --ignore-scripts https://github.com/dboeckli/ai-agent-skills.git#master
& "$(npm root -g)/@dboeckli/ai-agent-skills/scripts/install-skills.ps1"
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.

ai-agent-skills CLAUDE.md is an instructions file published in the GitHub repository dboeckli/ai-agent-skills (0 stars, last pushed 15d ago), licensed MIT. It adds 1,110 tokens to every session, about $0.0056 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
