uv

A set of project rules for managing Python packages with uv, a tool that installs, runs, and locks Python dependencies.

In plain words
What is it for?
Adding, removing, synchronising, and locking Python dependencies, and running Python scripts with their declared environments.
Why use it?
It keeps dependency installation and lock files consistent by requiring one package manager instead of mixing uv with pip or Poetry.

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.

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

uv 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.

What it actually says

Package Management with uv

These rules define strict guidelines for managing Python dependencies in this project using the uv dependency manager.

✅ Use uv exclusively

  • All Python dependencies must be installed, synchronized, and locked using uv.
  • Never use pip, pip-tools, or poetry directly for dependency management.

🔁 Managing Dependencies

Always use these commands:

# Add or upgrade dependencies
uv add <package>

# Remove dependencies
uv remove <package>

# Reinstall all dependencies from lock file
uv sync

🔁 Scripts

# Run script with proper dependencies
uv run script.py

You can edit inline-metadata manually:

# /// script
# requires-python = ">=3.12"
# dependencies = [
#     "torch",
#     "torchvision",
#     "opencv-python",
#     "numpy",
#     "matplotlib",
#     "Pillow",
#     "timm",
# ]
# ///

print("some python code")

Or using uv cli:

# Add or upgrade script dependencies
uv add package-name --script script.py

# Remove script dependencies
uv remove package-name --script script.py

# Reinstall all script dependencies from lock file
uv sync --script script.py

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.

uv is a cursor rule published in the GitHub repository QuincyMillerDev/ilograph-mcp-server (3 stars, last pushed 10mo ago), licensed MIT. It adds 297 tokens to every session, about $0.0015 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 2026-08-31.
