cursorrules

A set of coding rules for Python projects. It specifies language features, preferred standard-library tools, error handling, type hints, diagnostics, dependency changes, and lint checks.

In plain words
What is it for?
Use it to guide Python implementation and review, including pathlib usage, typed public functions, named exceptions, logging, and running Ruff.
Why use it?
It makes coding decisions consistent and catches style or quality issues before code is pushed. It also records practices the project does not allow.

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

cursorrules 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

Cursor rules — wordcount

Coding style:

  • Use Python 3.10+ features (match statements, X | Y union types).
  • Prefer pathlib.Path over os.path.
  • No bare except: — always name the exception type.
  • All public functions have type hints.
  • Run ruff check . before pushing; fix the warnings, don't silence them.

Do not:

  • Add dependencies without discussing first.
  • Catch Exception to "make tests pass."
  • Use print for diagnostics in library code (use logging).
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.

cursorrules is a cursor rule published in the GitHub repository techtalk/ai-readiness-assessment (9 stars, last pushed 15d ago), licensed Apache-2.0. It adds 119 tokens to every session, about $0.0006 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.
