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 | $0.00813 | $0.00813 |
| Opus 5.5 | $0.00325 | $0.00325 |
| Sonnet 5.5 | $0.00163 | $0.00163 |
| Haiku 4.5 | $0.00081 | $0.00081 |
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 1mo 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.

Skill Structure
Each skill is a directory with a SKILL.md file:
skills/<category>/<name>/
├── SKILL.md # Required — frontmatter + instructions
└── references/ # Optional — lazy-loaded reference files
└── <topic>.md
Frontmatter rules (verified against official docs)
Skills (SKILL.md):
- Required:
name,description - Recommended: trigger phrases in description ("Use when..." / "Make sure to use this skill whenever...")
- Optional:
paths(glob auto-activation),argument-hint,disable-model-invocation,user-invocable,allowed-tools,effort - Description budget: combined

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.
