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.

Model	Per session	Once invoked
Fable 5.1	$0.01570	$0.01570
Opus 5.5	$0.00628	$0.00628
Sonnet 5.5	$0.00314	$0.00314
Haiku 4.5	$0.00157	$0.00157

Security

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 2mo 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.

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

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.
