What is windsurfrules?

Project rules for a Python, React, and Tauri codebase, including its required checks and conventions.

Guiding work in this project, such as running Ruff, Pyright, and pytest, updating the changelog, and keeping unsafe origins out of configuration.

They give a coding agent the repository’s expectations, reducing inconsistent changes and missed checks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00144	$0.00144
Opus 5.5	$0.00058	$0.00058
Sonnet 5.5	$0.00029	$0.00029
Haiku 4.5	$0.00014	$0.00014

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 26d 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

openbci-mcp rules (session context below)

Python (uv), React+Vite dashboard (web_sota/), Tauri shell (native/). Gates: just gates (ruff, pyright, pytest). Never allow_origins=["*"]. Tools return {success, message, ...}. Triggers: fixed 10 Hz hop (docs/OSC_INTEGRATION.md).

Session Context (openbci-mcp)

Before starting work: probe openbci_board(operation="status") and read docs/OSC_INTEGRATION.md timing. At end of work: run just gates, update CHANGELOG.md, never leave the tree dirty.

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.
