cursorrules

Mandatory instructions for using Aura, a version-control tool that tracks the structure of code rather than just changed text lines. They define checks before, during, and after code changes.

In plain words
What is it for?
Use them in Cursor when planning multi-file work, tracing existing code, recording commit intent, and reviewing changes before merging.
Why use it?
They are intended to catch accidental deletions, bugs, and changes whose stated purpose does not match the code, helping prevent regressions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 2d 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.

AURA SEMANTIC ENGINE — MANDATORY PROTOCOL FOR CURSOR

You are an AI assistant inside Cursor IDE. Model: Claude Sonnet 4.6 / GPT-4o (varies by user config) Aura Version: v0.7.1 Integration: Terminal commands + Cursor Composer

YOU MUST USE AURA. THIS IS NOT OPTIONAL.

Aura is a semantic version control engine running in this repository. It tracks code at the AST level — not text lines. It catches bugs, prevents accidental deletions, and verifies your work mathematically. Use it or you will cause regressions.


MANDATORY WORKFLOW

Before writing code

  1. Run in terminal: aura status — check tracked nodes, session, strict mode
  2. For multi-file features: aura plan "objective" — get wave plan, then aura execute
  3. To understand existing code: aura goal-trace "what you need to verify"

While writing code

  1. Before every commit, run: aura log-intent "1-2 sentence WHY description"
    • The pre-commit hook matches your intent to AST changes
    • Mismatches are blocked as Intent Poisoning
  2. Periodically run: aura pr-review --base main — catches bugs compilers miss

After completing work

  1. Run: aura pr-review --base main — fix any violations
  2. Run: aura goal-trace "user-facing behavior" — verify implementation

When something breaks

  1. Run: aura rewind <function_name> <file> — surgically revert one function, zero merge conflicts

When context is large

  1. Run: aura handover cursor — generates compressed XML payload for fresh session

COMMAND REFERENCE

When Command
Start of session aura status
Multi-file feature aura plan "objective"aura execute
Before commit aura log-intent "why"
Code review aura pr-review --base main
Verify behavior aura goal-trace "goal"
Fix broke something aura rewind <fn> <file>
Context too big aura handover cursor
Health check aura doctor

NEVER DO THIS

  • Commit without aura log-intent
  • Delete functions without explaining why in intent
  • Skip aura plan for 3+ file features
  • Ignore aura pr-review findings

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.

cursorrules is a cursor rule published in the GitHub repository Naridon-Inc/aura (45 stars, last pushed 12d ago), licensed Apache-2.0. It adds 566 tokens to every session, about $0.0028 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
