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 | $0.01360 | $0.01360 |
| Opus 5.5 | $0.00544 | $0.00544 |
| Sonnet 5.5 | $0.00272 | $0.00272 |
| Haiku 4.5 | $0.00136 | $0.00136 |
Grade A, and why
python-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.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENT CONTRACT — READ BEFORE EVERY CODING TASK
- Read this file entirely before writing any code.
- Check
[project] requires-pythoninpyproject.tomlbefore using ANY version-specific syntax. - Load
skills/common/code-style.mdfor every task — no exceptions. - Load the framework-specific
skills/{framework}/SKILL.mdfor the project's framework. - Load domain-specific skills (
skills/common/security.md,db-design.md, etc.) when relevant. - Cite the rule you are enforcing when you make a style or architectural decision.
- Ask before assuming framework version, DB engine, auth mechanism, or Python version.
- Never delete existing migrations, test files, or
.env.exampleentries. - When in doubt between two approaches, choose the one that is more explicit and testable.

| 15 | All monetary values use Decimal, never float | db-design.md §7 |
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.

python-skills CLAUDE.md is an instructions file published in the GitHub repository rishapgandhi/python-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 1,360 tokens to every session, about $0.0054 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.
