A command for extracting useful memories after a completed project task and reorganising the stored memory collection. REM sleep here means a memory-maintenance process, not human sleep.

It can extract memories from a named specification, run memory rebalancing, automatically apply non-conflicting changes, and ask the user to resolve decisions or conflicts when needed.

It turns completed work into reusable project knowledge and can rebalance the memory collection to keep it useful.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01794
Opus 5.5	$0.00000	$0.00718
Sonnet 5.5	$0.00000	$0.00359

Security

Grade A, and why

crux-dream 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.

crux-dream

Post-execution memory extraction and REM sleep rebalancing.

Repository: github.com/zotoio/CRUX-Compress

Usage

/crux-dream <spec-name>              - Extract memories from a completed spec
/crux-dream --rem                    - Run REM sleep (rebalance all memories)
/crux-dream --rem --yolo             - Run REM sleep, auto-apply non-conflict changes

Instructions

When this command is invoked, spawn one of the mode-scoped memory thin agents to handle the workflow — crux-memory-dream for a spec-name invocation, or crux-memory-rem for --rem / --rem --yolo. Each thin agent orchestrates the memory skills it needs (crux-skill-memory-extract, crux-skill-memory-rebalance, crux-skill-memory-crud, crux-skill-memory-compress, crux-skill-memory-reference-tracker, crux-skill-memory-index) to perform extraction or rebalancing.

User input escalation — CRITICAL: This command uses Pattern B (work first, then escalate). The subagent NEVER calls AskQuestion directly — the parent agent owns all user prompts and resumes the subagent with the answers. 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.

Foreground execution — CRITICAL: The subagent MUST run in the foreground (run_in_background: false). Background subagents only return a truncated summary notification to the parent — the full analysis is lost. Foreground execution blocks the parent until the subagent completes and returns its complete response, which the parent then displays verbatim to the user.

Full output relay — CRITICAL: The parent agent MUST relay the subagent's complete response to the user without summarizing, truncating, or paraphrasing. The subagent's response contains the full spec analysis — artifact examination, candidate ranking, conflict reports, resolved bug detection — and all of this must be visible to the user before any decisions are requested. If the response is long, display it in full; do not condense 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.

crux-dream is a command published in the GitHub repository zotoio/CRUX-Compress (8 stars, last pushed 14d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,794 tokens. 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 2026-08-31.
