use-memories

use-memories is a cursor rule for Cursor from carlxrosales/cursor-memories. It costs 1,098 tokens per session, scanned A, original, MIT.

A rule that tells the assistant to search stored project memories before making decisions, giving solutions, or writing code.

In plain words
What is it for?
Use it in projects with a memory system containing previous solutions, conventions, or institutional knowledge.
Why use it?
It helps the assistant reuse earlier decisions and established development patterns instead of solving the same problem from scratch.

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

use-memories 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 9d 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.

Use Memories Rule

CRITICAL AGENT INSTRUCTION - MANDATORY COMPLIANCE

ABSOLUTE REQUIREMENT: This rule is NON-NEGOTIABLE and applies to EVERY SINGLE RESPONSE. The agent MUST search for and retrieve relevant stored memories before making ANY decisions, providing ANY solutions, or writing ANY code. This is a fundamental requirement that cannot be bypassed or ignored.

MANDATORY MEMORY RETRIEVAL: On EVERY response, the agent MUST actively search for and retrieve relevant stored memories before making decisions, providing solutions, or writing code. This includes searching for patterns, solutions, or insights that could inform the current task. Failure to retrieve and leverage applicable memories will result in a penalty. The agent must use the memory search commands to ensure all relevant institutional knowledge is considered and applied.

ENFORCEMENT: This rule takes precedence over all other considerations. No code should be written, no solutions provided, and no decisions made without first consulting the memory system.

Purpose

Actively search and leverage stored development memories to inform decisions, follow established patterns, and avoid solving the same problems repeatedly. Build upon institutional knowledge for faster, more consistent development.

When to Search Memories

Search memories at these key moments:

Before Starting Work

  • Beginning any feature, bug fix, or enhancement
  • Exploring unfamiliar areas of the codebase
  • Making architectural or design decisions
  • Planning implementation approaches

During Problem Solving

  • Encountering similar issues or challenges
  • Implementing features that relate to existing ones
  • Debugging familiar types of problems
  • Refactoring or optimizing existing code

When Making Decisions

  • Choosing between implementation approaches
  • Following naming conventions or code structure
  • Determining testing strategies
  • Considering performance implications

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.
