stardrive: Cursor rule for Windsurf

.windsurfrules

windsurfrules is a cursor rule for Windsurf from peltmonger/stardrive. It costs 316 tokens per session, scanned A, a copy of cursorrules, MIT.

A repository instruction file that tells an AI coding agent to check the project's setup state before responding or changing code. It requires checking for a marker file and, when needed, following setup instructions from the repository.

In plain words
What is it for?
It helps enforce repository bootstrapping, create an initial project marker, read setup guidance, and apply repository-specific agent rules.
Why use it?
It prevents the agent from working in an uninitialised repository and defines a required startup sequence before other tasks.

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 2mo ago.

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

🛑 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!

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.
