CRUX-Compress: Command for Claude Code

.cursor/commands/crux-remember.md

crux-remember is a command for Claude Code, Cursor from zotoio/CRUX-Compress. It costs 0 tokens per session (674 once invoked), scanned A, original, MIT.

A chat command for saving a new insight or piece of project knowledge in the CRUX memory collection.

In plain words
What is it for?
Creating a memory interactively or from supplied text, with an optional type such as a learning.
Why use it?
It gives you a way to record useful information outside the project’s formal specification process, so it can be included in later memory maintenance.

Command for Claude CodeCursor

Written for Claude Code and Cursor: $ARGUMENTS substitution, but also installed under .cursor/. Also seen: mentions subagents; mentions AGENTS.md.

This is zotoio/CRUX-Compress's own configuration. It tells Claude Code and Cursor how to work on CRUX-Compress 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 CRUX-Compress 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

crux-remember 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.

How it starts

The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

crux-remember

Store ad-hoc memories outside of spec workflows. These memories participate in standard consolidation during REM sleep.

Repository: github.com/zotoio/CRUX-Compress

Usage

/crux-remember                              - Interactively create a new memory
/crux-remember "insight text"               - Create a memory from the provided text
/crux-remember "insight" --type learning    - Create with pre-specified type

Instructions

This command primarily uses Pattern A (pre-collect then spawn) — the parent agent collects the user's choices (type, tags, description) via AskQuestion FIRST, then spawns a crux-memory-remember subagent with the pre-collected answers. If creation surfaces an unexpected decision (e.g. conflict, size limit), the subagent falls back to Pattern B and returns needs_user_input. The subagent NEVER calls AskQuestion directly. For the full Pattern A / Pattern B contract and the needs_user_input YAML schema, see .cursor/skills/_memory-shared.md#user-input-escalation and AGENTS.md.

Argument Handling

  • No arguments: Prompt the user for the memory content/insight they want to save.
  • Quoted text (e.g. "always validate checksums before overwrite"): Use as the memory title/body. Pass $ARGUMENTS to the subagent.
  • --type <type>: If provided, skip the type selection prompt and use the specified type directly.

What Happens

Phase 1 — Parent collects user input (before spawning subagent):

  1. If no text was provided, ask the user what they want to remember
  2. Use the AskQuestion tool to ask the user to select the memory type. Present options from the typeTransitions keys in config: idea, learning, redflag, core, goal. If --type was provided, skip this step.
  3. Use the AskQuestion tool to ask the user for optional tags (comma-separated) and a brief description. Suggest relevant tags based on the memory content and current context.

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.
