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 | $0.13109 | $0.13109 |
| Opus 5.5 | $0.05244 | $0.05244 |
| Sonnet 5.5 | $0.02622 | $0.02622 |
| Haiku 4.5 | $0.01311 | $0.01311 |
Grade C, and why
whygraph CLAUDE.md scanned grade C 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 yesterday.
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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
1. `curl -fsSL …/install.sh | sh` (see below) puts the `whygraph` shim (and the `whygraph-mcp` removal stub) on `PATH`. Docker is the only install channel (there is no PyPI, `uv tool install` or `pipx` path). Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.
