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 | $0.01570 | $0.01570 |
| Opus 5 | $0.00785 | $0.00785 |
| Sonnet 5 | $0.00314 | $0.00314 |
| Haiku 4.5 | $0.00157 | $0.00157 |
Grade A, and why
cursorrules CLAUDE.md scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Project Overview
This is a repository for managing and distributing Cursor AI rules, particularly focused on web development with strong emphasis on PHP/Drupal, frontend frameworks, and security best practices. The project provides an interactive PHP installer that allows developers to selectively install rule sets into their projects.
Common Development Tasks
Running Tests
# Run all tests
cd .tests && ./run-all-tests.sh
# Run individual test scripts
cd .tests
./test-copy.sh # Test basic installation functionality
./test-debug.sh # Test debug mode
./test-invalid-option.sh # Test invalid option handling
./test-conflicting-options.sh # Test conflicting options
./test-missing-files.sh # Test missing file handling
Testing the Installer
# Test installation interactively
php install.php
# Test with specific options
php install.php --core # Install core rules only
php install.php --web-stack # Install web stack rules (includes core)
php install.php --python # Install Python rules (includes core)
php install.php --all # Install all rules
# Test with debug mode
php install.php --debug --core
# Test installation to custom directory
php install.php --all --destination=my/custom/path
# Test installation via curl (non-interactive)
curl -s https://raw.githubusercontent.com/ivangrynenko/cursor-rules/main/install.php | php -- --ws
cat install.php | php -- --core # Test piped input locally
Linting and Code Quality
- PHP syntax validation:
php -l install.php - No specific linting commands configured - consider adding phpcs/phpmd
Architecture and Code Structure
Project Organization
- install.php: Main installer script (current version defined by CURSOR_RULES_VERSION constant)
- .cursor/rules/: Contains 56 MDC rule files organized by category
- .cursor/UPDATE.md: Installation receipt file tracking installed version and configuration (created by installer)
- .tests/: Bash test scripts for installer validation
- .github/workflows/: CI/CD pipeline using GitHub Actions for PHP 8.3
- AGENTS.md: Comprehensive guide for using Cursor Rules (created by installer)
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 CLAUDE.md is an instructions file published in the GitHub repository ivangrynenko/cursorrules (88 stars, last pushed 10mo ago), licensed MIT. It adds 1,570 tokens to every session, about $0.0078 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
