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 | $0.00222 | $0.00222 |
| Opus 5 | $0.00111 | $0.00111 |
| Sonnet 5 | $0.00044 | $0.00044 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
sports-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 12d 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 - sports-skills Guidelines
Tech Stack
- Language: Python 3.9+
- Build System: hatch / hatchling
- Package/Dependency Manager: uv (uses uv.lock)
- Testing Framework: pytest
- Purpose: Lightweight Python SDK for structured sports data (Odds, Standings, Telemetry, News)
Commands
- Install Development Dependencies:
uv pip install -e ".[dev]" - Run Tests:
pytest - Run Sport-Specific Tests:
pytest tests/test_<sport>.py - Format & Lint:
ruff format .andruff check .
Code Conventions
- Error Handling: All skills are used by autonomous agents. They MUST fail gracefully with informative, text-based error messages instead of throwing unhandled stack traces.
- Rate Limiting: Respect API rate limits (e.g. ESPN, public endpoints, Polymarket). Cache aggressive or repetitive queries.
- Structure: Skills live under
skills/directory as individual folder packages (e.g.skills/football-data/).
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.
