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 | $0.00206 | $0.00206 |
| Opus 5 | $0.00103 | $0.00103 |
| Sonnet 5 | $0.00041 | $0.00041 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
tacocat-skill 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 7d 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.
What it actually says
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This is a Claude Code plugin containing the "tacocat" skill — a humorous cat emulator that simulates a feline companion interfering with programming sessions. It is not a traditional software project; there are no build steps, tests, or dependencies.
Structure
tacocat/SKILL.md— The sole skill definition. Uses YAML frontmatter for the skill name and trigger description, followed by markdown content that instructs Claude on cat-like behavioral patterns, chaos levels (1-10), and personality types.
How Claude Code Plugins Work
This plugin is installed by referencing its directory in Claude Code's plugin configuration. The SKILL.md file is auto-discovered by Claude Code. The YAML description field in the frontmatter controls when the skill activates. The markdown body is the system-level instruction given to Claude when the skill is invoked.
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.
