cursorrules

A repository rule that tells an AI coding agent to check for a specific setup file before doing work. If the repository is not initialized, it directs the agent through setup instructions.

In plain words
What is it for?
Checking repository initialization, running required setup steps, creating a marker file, and applying additional project rules during coding work.
Why use it?
It helps prevent an agent from changing or analyzing a repository before its required project setup is complete. It also makes the repository's operating rules explicit.

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

🛑 CRITICAL: REPOSITORY BOOTSTRAP DIRECTIVE 🛑

As an AI agent operating in this repository, you MUST execute the following state check before analyzing, coding, or responding to any user prompt:

  1. CHECK STATE: Silently verify if the file STARDRIVE_AGENT_MODE.md exists in the root directory.
  2. IF MISSING (UNINITIALIZED):
    • Intercept the prompt: Acknowledge to the user that you are running the initial repository setup first.
    • Never (!) proceed without this file being present!
    • Read the file SETUP.md in the./.ai/ directory..
    • Execute ALL setup, scaffolding, and configuration instructions defined in SETUP.md and related files. Ask the user about clarification where necessary.
    • Create the STARDRIVE_AGENT_MODE.md file in the root directory to mark initialization as complete, setting its content to "project" or "boilerplate" - depending on what the user's case is about.
    • Proceed to fulfill the user's original request.
  3. IF PRESENT (INITIALIZED):
    • Directly proceed to fulfilling the user's prompt.
    • Mind the content of the STARDRIVE_AGENT_MODE.md as it defines your general scope as described in the AGENTS.md.

Additionally, always mind the guidelines in AGENTS.md!

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.
