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 | $0.00825 | $0.00825 |
| Opus 5.5 | $0.00330 | $0.00330 |
| Sonnet 5.5 | $0.00165 | $0.00165 |
| Haiku 4.5 | $0.00082 | $0.00082 |
Grade A, and why
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 2mo 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to AI coding assistants when working with code in this repository.
Repository Purpose
A collection of AI agent skills — self-contained Markdown knowledge bases that AI coding assistants (Claude Code, Copilot CLI, Cursor, etc.) load to gain expertise on specific topics. Skills are distributed via npx skills add chaunsin/agent-skills.
Skill Anatomy
Each skill lives under skills/<name>/:
SKILL.md— Entry point with YAML frontmatter (name,description,metadata) and a comprehensive quick referencereferences/— Modular deep-dive files linked from SKILL.md for detailed syntax, edge cases, and workflowsscripts/— (optional) Helper scripts for validation, inventory, or installationagents/— (optional) Agent-specific configurations (e.g., OpenAI agent YAML)
The description frontmatter field is the activation trigger — it lists keywords and scenarios that cause the agent to load the skill.
testdata/ holds source material used during skill authoring. It is gitignored and must not contain hardcoded absolute paths.
Skill Authoring Conventions
- All skill content is written in English regardless of user language
- SKILL.md frontmatter fields:
name,description,metadata(author, version) - Cross-references between SKILL.md and reference files use relative paths
- Main SKILL.md provides a self-contained quick reference;
references/*.mdfiles split out detailed content - README.md and README_CN.md must stay in sync when skills are added/removed

Redis command-line interface — data querying, key scanning, server monitoring, latency analysis, vector search, ACL management, cluster management, scripting |
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.

agent-skills CLAUDE.md is an instructions file published in the GitHub repository chaunsin/agent-skills (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 825 tokens to every session, about $0.0033 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.
