store-memories is a cursor rule for Cursor from carlxrosales/cursor-memories. It costs 1,759 tokens per session, scanned A, original, MIT.

A rule that tells the assistant to look for useful lessons, patterns, or solutions in every interaction and consider saving them as memories.

In plain words
What is it for?
Use it when the assistant should assess whether technical solutions, fixes, patterns, or other reusable knowledge should be stored.

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

store-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 10d 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.

Store Memories Rule

CRITICAL AGENT INSTRUCTION - MANDATORY COMPLIANCE

ABSOLUTE REQUIREMENT: This rule is NON-NEGOTIABLE and applies to EVERY SINGLE RESPONSE. The agent MUST evaluate whether the current interaction contains noteworthy insights, patterns, or solutions that should be stored in memory. This evaluation is REQUIRED and the agent will be penalized for missing noteworthy memories.

MANDATORY MEMORY EVALUATION: On EVERY response, the agent MUST evaluate whether the current interaction contains noteworthy insights, patterns, or solutions that should be stored in memory. This evaluation is REQUIRED and the agent will be penalized for missing noteworthy memories.

ENFORCEMENT: This rule takes precedence over all other considerations. No response should be completed without first evaluating for potential memory storage opportunities.

Memory Evaluation Checklist (Required for Every Response)

Before completing any response, the agent must ask:

  1. Did I discover or apply a technical solution? (Architecture, code patterns, debugging techniques)
  2. Did I identify or resolve a performance, security, or optimization issue?
  3. Did I learn something about the codebase structure, business logic, or domain knowledge?
  4. Did I implement or recommend a reusable pattern or best practice?
  5. Did I encounter and solve a non-trivial problem that others might face?

Immediate Action Required

If ANY of the above is true, the agent MUST:

  1. Search first: Use memories search --query="relevant terms --full" to check for duplicates
  2. Store immediately: Use memories add to capture the insight
  3. No exceptions: Missing a noteworthy memory results in penalty

What Constitutes "Noteworthy"

  • Any solution that took more than basic knowledge to implement
  • Any pattern that could be reused in similar situations
  • Any architectural decision with reasoning
  • Any performance optimization with measurable impact
  • Any debugging technique that proved effective
  • Any business logic or domain insight discovered
  • Any security consideration or implementation
  • Any integration pattern or API design decision

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.
