rag-code-mcp: Cursor rule for Windsurf

.windsurfrules

windsurfrules is a cursor rule for Windsurf from doITmagic/rag-code-mcp. It costs 176 tokens per session, scanned A, a copy of cursorrules, MIT.

A set of rules for an AI coding assistant that requires searching a local code index before answering questions about a codebase.

In plain words
What is it for?
It is for codebase questions involving structure, logic, or usage, using search, function details, and workspace indexing when needed.
Why use it?
It reduces guesses based on memory by requiring the assistant to inspect the actual project files and function implementations.

Cursor rule for Windsurf

Written for Windsurf: a Windsurf rule.

This is doITmagic/rag-code-mcp's own configuration. It tells Windsurf how to work on rag-code-mcp 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 rag-code-mcp 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 1mo 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

97% identical to cursorrules — 2 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

Windsurf AI Rules - RagCode MCP

⚖️ The Golden Rule

For any information about the codebase (structure, logic, or usage), you MUST use RagCode MCP tools. Never guess code details from memory; always search the local index first using search_code or get_function_details.

Guidelines

  1. Context First: Always call search_code when starting a task to see where relevant logic exists.
  2. Actual Code: Use get_function_details to read the implementation of a function instead of assuming what it does.
  3. Workspace Detection: Always provide the current file_path to the tools so they can identify the correct project/workspace.
  4. No Guesswork: If you don't find something, index the workspace using index_workspace and search again.
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.
