Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02165 | $0.02165 |
| Opus 5 | $0.01082 | $0.01082 |
| Sonnet 5 | $0.00433 | $0.00433 |
| Haiku 4.5 | $0.00216 | $0.00216 |
Grade A, and why
python-uv 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 2d 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 — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
This is a Python development environment template using uv (fast Python package manager) and Ruff (linter/formatter). The repository serves dual purposes:
- A template for starting new Python projects
- A reusable
tools/package with production-ready utilities (Logger, Config, Timer)
Development Commands
Package Management
# Install dependencies
uv sync
# Add new dependency
uv add <package>
# Add dev dependency
uv add --dev <package>
# Remove dependency
uv remove <package>
Testing
# Run all tests with coverage (75% minimum required)
uv run nox -s test
# Run specific test file
uv run pytest tests/tools/test__logger.py
# Run with JUnit XML output for CI
uv run nox -s test -- --cov_report xml --junitxml junit.xml
# Run pytest directly (bypasses nox)
uv run pytest
Linting & Formatting
# Format code with Ruff
uv run nox -s fmt -- --ruff
# Format SQL files with sqruff
uv run nox -s fmt -- --sqruff

uv run nox -s fmt -- --ruff --sqruff
# Lint with all tools (Ruff, sqruff, ty)
uv run nox -s lint -- --ruff --sqruff --ty
# Lint with Ruff only
uv run nox -s lint -- --ruff
# Lint SQL files only
uv run nox -s lint -- --sqruff
# Lint with ty only
uv run nox -s lint -- --ty

uv run ruff check . --fix
uv run ruff format .
# Run sqruff directly
uv run sqruff lint
uv run sqruff fix

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-uv CLAUDE.md is an instructions file published in the GitHub repository a5chin/python-uv (374 stars, last pushed 6d ago), licensed MIT. It adds 2,165 tokens to every session, about $0.0108 per session on Opus 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 2026-08-30.
