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 | $0.00396 | $0.00396 |
| Opus 5 | $0.00198 | $0.00198 |
| Sonnet 5 | $0.00079 | $0.00079 |
| Haiku 4.5 | $0.00040 | $0.00040 |
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 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.
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
⚠️ MANDATORY PRE-IMPLEMENTATION CHECKLIST ⚠️
STOP! Before writing ANY code or suggesting ANY changes:
-
🔍 SEARCH FIRST:
# REQUIRED: Run these searches and document results grep_search for functionality file_search for similar files list_dir in relevant directories -
📝 DOCUMENT FINDINGS:
# REQUIRED: Fill this out ## Existing Files Found: - [List all relevant files found with full paths] - [Include file sizes and last modified dates if relevant] ## Existing Functionality: - [Describe what already exists in detail] - [Note any patterns or architectural approaches used] ## Gaps Identified: - [List what's missing or needs enhancement] - [Identify technical debt or issues in existing code] ## Implementation Decision Tree: - Is there existing code that serves this purpose? [Yes/No] - Can existing code be enhanced to meet requirements? [Yes/No] - Is creating new code justified? [Yes/No, with reasoning] ## Proposed Approach: - [ ] Enhance existing code at [file path] - [ ] Create new files (requires detailed justification) - [ ] Refactor existing code at [file path] ## Implementation Plan: 1. [First step with estimated effort] 2. [Second step with estimated effort] 3. [Additional steps as needed] -
✋ WAIT FOR APPROVAL:
- Present findings to user with clear options
- Get explicit approval for chosen approach
- Never proceed with new files if similar functionality exists
- Document approval in the implementation plan
❌ IF YOU SKIP THIS CHECKLIST, YOU ARE VIOLATING THE MOST IMPORTANT RULE ❌
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 Kabi10/cursor-rules (21 stars, last pushed 2mo ago), licensed MIT. It adds 396 tokens to every session, about $0.0020 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 2026-08-30.
