A cleanup guide for stored Cogitation memories, including decisions, learnings, patterns, and project settings.

In plain words
What is it for?
Use it to list memories, analyze them by type and area, present an audit, remove unwanted entries, and verify the result.
Why use it?
It helps find duplicate, outdated, vague, misplaced, or invalid memories that could make future project work less useful.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.

Security

Grade A, and why

audit 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.

Audit EC Memories

Review, clean, and organize stored memories.

Announce: "I'm using the audit skill to review EC memories."

The Flow

List All → Analyze → Present → Clean → Verify

Step 1: List All Memories

Pull everything by type:

ec_list:
  limit: 100
  type: decision

ec_list:
  limit: 100
  type: learning

ec_list:
  limit: 100
  type: pattern

ec_list:
  limit: 100
  type: config

Also check for invalidated entries:

ec_list:
  limit: 50
  include_invalid: true

Step 2: Analyze

Check for Issues

  1. Duplicates - Same or very similar content
  2. Stale - References outdated code/patterns
  3. Vague - Content too generic to be useful
  4. Miscategorized - Wrong type for the content

Group by Area

Organize memories by their area tag to see coverage:

  • Which areas have many memories?
  • Which areas are sparse?
  • Any orphaned areas (code deleted)?

Step 3: Present Summary

## EC Memory Audit

**Total Memories:** N (D decisions, L learnings, P patterns, C config)
**Invalidated:** N

### By Area
| Area | Decisions | Learnings | Patterns |
|------|-----------|-----------|----------|
| auth | 3 | 2 | 1 |
| api  | 1 | 4 | 2 |
| ...  | ... | ... | ... |

### Issues Found
- **Duplicates (N):** [list IDs]
- **Potentially stale (N):** [list with reason]
- **Vague entries (N):** [list IDs]

Step 4: Clean Up

Use AskUserQuestion for each category:

{
  "questions": [{
    "question": "How should I handle the N duplicate memories?",
    "header": "Duplicates",
    "options": [
      { "label": "Merge", "description": "Keep best version, invalidate others" },
      { "label": "Keep all", "description": "They might have nuance" },
      { "label": "Review each", "description": "Show me one by one" }
    ],
    "multiSelect": false
  }]
}

Invalidating Memories

When removing a memory, use ec_invalidate with optional superseding:

ec_invalidate:
  id: <old_memory_id>
  superseded_by: <new_memory_id>  # Optional: link to replacement

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.
