cursorrules

A set of Cursor editor rules that tells an AI coding assistant which project context and standards to read, in increasing order of specificity. Cursor is a code editor with built-in AI assistance.

In plain words
What is it for?
Configuring file indexing, TypeScript assistance, workspace-wide searches, and the context sources used during coding and refactoring.
Why use it?
It gives the assistant consistent repository, TypeScript, collection, and project guidance while keeping Cursor-specific settings separate from general coding conventions.

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.

What it actually says

Cursor Rules

Read context from (in order of increasing specificity):

  1. Repository: ../repository-context/AGENTS.md
  2. Standards: ../repository-context/docs/standards/typescript.md
  3. Collection: ../repository-context/collections/typescript-web-service.md
  4. This project: README.md

Cursor-Specific Settings

  • Index all files except: node_modules, dist, .cache, coverage
  • Use workspace-wide search for cross-file refactoring
  • Enable TypeScript IntelliSense for all files

Note

This file contains only Cursor-specific settings. For all coding conventions, read the context files listed above.

The same conventions apply whether you use Cursor, GitHub Copilot, Aider, or other AI assistants.

Changes

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.
