cursorrules

A navigation and validation toolkit for coding agents working in large repositories. It uses context files, task routes, completeness requirements, and search boundaries to guide how agents inspect code.

In plain words
What is it for?
Use it to define where an agent should search, what it must include in its response, and how to create or validate repository context.
Why use it?
It helps prevent agents from opening unrelated files or missing required parts of an answer. It also provides templates, validation scripts, and a command-line tool for writing context packs.

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.

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

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.

Origin

This is a copy

100% identical to cursorrules — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

  1. Read .agent-context/current/routes.json to identify task type
  2. Load contracts from .agent-context/current/completeness_contract.json + .agent-context/current/search_scope.json
  3. Search ONLY within scoped directories defined in search_scope.json
  4. Do not open repo source files before step 3

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.
