uv

A set of rules for using uv, a Python tool for creating projects, managing packages, locking dependencies, and running code in a project environment.

In plain words
What is it for?
Use it for Python project initialization, adding or removing packages, updating the lock file, syncing the environment, and running commands with uv.
Why use it?
It gives the agent a consistent way to set up the project and keep its Python dependencies and environment in sync.

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 C, and why

uv scanned grade C with 2 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 yesterday.

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.

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 Datai-Network/datai-mcp-server (3 stars, last pushed 1y ago), with no licence file. It adds 6,470 tokens to every session, about $0.0324 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
