template: Cursor rule for Cursor

.cursorrules

cursorrules is a cursor rule for Cursor from snowdreamtech/template. It costs 361 tokens per session, scanned A, a copy of cursorrules, MIT.

A repository instruction file that requires a coding agent to read the project’s rules before answering or running code. It points the agent to the .agent/rules directory and its loading order.

In plain words
What is it for?
Use it as a redirect for Claude Code and other coding agents working in repositories with centralised rule files.
Why use it?
It reduces the chance that an agent will ignore repository-specific conventions or exceed the available context by loading everything at once.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/. Also seen: built for cline.

This is snowdreamtech/template's own configuration. It tells Cursor how to work on template 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 template 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

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 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

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 SYSTEM INSTRUCTION 🚨

Before answering ANY prompt or executing ANY code in this repository, you MUST first read and strictly adhere to ALL the rules defined in the following directory:

Rules Location

📁 .agent/rules/

🚨 CRITICAL TOKEN LIMIT PROTOCOL 🚨

Do NOT load all files in .agent/rules/ simultaneously. You will exceed the context window.

You MUST follow this strict loading sequence:

  1. Load Core Fundamentals: Always read 01-general.md through 12-docs.md.
  2. Consult the Lazy-Loading Router: Read .agent/rules/00-index.md to discover technology-specific rules.
  3. Load On Demand: Based on the index, load ONLY the specific .md files relevant to your current task (e.g., react.md for a React task).

Why This File Exists

This project uses a unified rule system to ensure consistent AI behavior across all AI-powered IDEs and tools (Cursor, Windsurf, GitHub Copilot, Cline, Claude, Gemini, Trae, Roo Code, Augment, Amazon Q, Kiro, Continue, Junie, etc.). This file is a redirect entry point — the actual rules live in .agent/rules/ as the Single Source of Truth.

Failure to follow the rules inside .agent/rules/ and the Lazy-Loading protocol is completely unacceptable.

Slash Commands / Workflows

All AI slash commands and standard operating procedures (SOPs) are located in .agent/workflows/. If the user invokes a command like /speckit.plan, execute the corresponding markdown file in that directory.

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.
