Token cost

What it costs to keep this loaded

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.

Security

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 2mo 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 . and ruff 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/).
Changes

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.
