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

cursor-rules 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 1mo 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.

Cursor Rules Location

How to add new cursor rules to the project

  1. Always place rule files in PROJECT_ROOT/.cursor/rules/:

    .cursor/rules/
    ├── your-rule-name.mdc
    ├── another-rule.mdc
    └── ...
    
  2. Follow the naming convention:

    • Use kebab-case for filenames
    • Always use .mdc extension
    • Make names descriptive of the rule's purpose
  3. Directory structure:

    PROJECT_ROOT/
    ├── .cursor/
    │   └── rules/
    │       ├── your-rule-name.mdc
    │       └── ...
    └── ...
    
  4. Never place rule files:

    • In the project root
    • In subdirectories outside .cursor/rules
    • In any other location
  5. Cursor rules have the following structure:

---
description: Short description of the rule's purpose
globs: optional/path/pattern/**/* 
alwaysApply: false
---
# Rule Title

Main content explaining the rule with markdown formatting.

1. Step-by-step instructions
2. Code examples
3. Guidelines

Example:
```typescript
// Good example
function goodExample() {
  // Implementation following guidelines
}

// Bad example
function badExample() {
  // Implementation not following guidelines
}
```

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.
