cortex-consolidate

A memory-maintenance add-on for cleaning up and reorganising stored memories. It can reduce old memories to shorter summaries or tags and move frequently used event memories into longer-term knowledge.

In plain words
What is it for?
Use it after long sessions or bulk imports, or periodically, to cool down, compress, consolidate, and review stored memories.
Why use it?
It helps control stale or noisy memory and preserve information that is accessed often. It also finds possible cause-and-effect links and replays important memory groups.

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

cortex-consolidate 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.

Consolidate — Memory Maintenance and Evolution

Keywords

consolidate, maintenance, cleanup, compress, decay, merge, evolve, sleep, replay, consolidation, memory health, prune, clean up, optimize memories, reduce noise

Overview

Run the full memory maintenance pipeline — modeled after biological memory consolidation. This includes heat decay (cooling unused memories), compression (full text to gist to tags), CLS consolidation (episodic to semantic), causal graph discovery, and sleep-like replay that strengthens important memory clusters.

Use this skill when: After a long session, after bulk imports, periodically (weekly), or when memory_stats shows too many hot memories or high noise.

Workflow

Step 1: Run Full Consolidation

cortex:consolidate({})

This runs the complete pipeline:

  1. Decay cycle — Cool memories by heat * decay_factor. Memories below cold threshold (0.05) become candidates for compression
  2. Compression — Old memories compress through stages: full text (7+ days) to gist, gist (30+ days) to tags
  3. CLS consolidation — Frequently-accessed episodic memories promote to semantic store (like hippocampal-to-cortical transfer)
  4. Causal discovery — PC Algorithm runs on entity co-occurrences to discover causal relationships
  5. Sleep compute — Dream-like replay strengthens clusters, summarizes related memories, and re-embeds compressed content

Step 2: Review Results

The response includes:

  • memories_decayed — how many cooled down
  • memories_compressed — how many were compressed (and to what level)
  • memories_consolidated — how many promoted from episodic to semantic
  • causal_edges_discovered — new relationships found
  • replay_clusters — memory clusters that were replayed and strengthened

Step 3: Selective Operations

For targeted maintenance instead of the full pipeline:

Forget specific memories:

cortex:forget({
  "memory_id": <id>,
  "hard": false
})

Soft delete (sets heat to 0) by default. Use "hard": true for permanent deletion. Protected memories require explicit "force": true.

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.

cortex-consolidate is a skill published in the GitHub repository cdeust/Cortex (71 stars, last pushed 4d ago), licensed MIT. It adds 84 tokens to every session and 732 once invoked, about $0.0004 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.
