Turn Cursor Into a Verified A+ Python Repository in 60 Seconds
Without a compiled CLAUDE.md and .cursorignore, coding agents scanning anysphere/cursor burn 47,606 discovery tokens/turn across .venv/, __pycache__/, *.pyc, uv.lock, poetry.loc.

# CLAUDE.md โ Progressive-Disclosure Root TOC for `anysphere/cursor` (<500 Tokens) [](https://exactbaseline.com/audit/anysphere/cursor) > **Why <500 Tokens?** Frontier coding agents suffer instruction decay when root `CLAUDE.md` files exceed 800 tokens. Keep this root file as a strict Table of Contents and load scoped `.cursor/rules/*.mdc` modules only when editing matching paths. ## 1. Hard Context-Tree Pruning (Saves 27,612 Tokens/Turn | -58%) - **NEVER read, grep, or index**: `.venv/, __pycache__/, *.pyc, uv.lock, poetry.lock, .pytest_cache/, dist/, build/` - **Per-Turn Context Budget**: <= `19,994` tokens (Baseline unindexed: `47,606` tokens/turn). - **File Cap**: Keep every module < 1,000 lines; query symbol signatures before reading files > 250 lines. ## 2. Progressive-Disclosure Rule Modules (Load On-Demand) - `/.cursor/rules/architecture.mdc` -> Python module boundaries, schema validation (`Pydantic v2 TypeAdapter + Instructor/BAML strict JSON boundary validation`). - `/.cursor/rules/security-and-tests.mdc` -> Verification gate (`uv run pytest -q && ruff check .`), OWASP LLM01 & secret hygiene. - `/litellm-cost-router.yaml` -> 65% fast/local + 35% frontier KV-cache routing (saves `$322.17/mo`).
