Cursor rule for Windsurf

Written for Windsurf: a Windsurf rule. Also seen: mentions AGENTS.md.

This is peltmonger/stardrive's own configuration. It tells Windsurf how to work on stardrive itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything stardrive configures →

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

windsurfrules 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 today.

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.
