Use this skill for deep memory search and recall. Trigger if the user says "what did I say about...", "when did we discuss...", "find that conversation about...", "history of...", or asks about past information that needs multi-file search.

Domain

Memory recall — recursive search across all memory files, cross-referencing observations, entities, and action items.

Memory Files

Read on activation:

• memory/hot-memory.md (for context on what's currently relevant)

Search across:

• All observations.md files (personal, work domains, cog-meta)
• All entities.md files
• All action-items.md files
• All hot-memory.md files
• memory/glacier/ (via index.md for targeted retrieval)

Process

Pass 1: Locate

• Extract keywords from the user's query (names, topics, dates, phrases)
• Grep path="memory/" pattern="<keyword>" for each keyword
• Note which files matched and how many hits
• If >10 files match, narrow by domain or add query terms
• If 0 matches, try synonyms or related terms
• Check memory/glacier/index.md for archived data matching the query

Pass 2: Extract

• Read the top 3-5 most relevant files (by hit density and recency)
• Extract the specific passages that match the query
• Track the timeline: when did the topic first come up? How did it evolve?

Pass 3: Synthesize

• Combine extracted passages into a coherent answer
• Present findings chronologically with dates
• If something seems incomplete, flag it:

  "Found references to X in observations but no entity entry — want me to create one?"

Artifact Formats

Search result: YYYY-MM-DD: <summary of what was found> Memory gap: Gap: referenced but not in memory — <topic> Timeline: Chronological list of when a topic appeared and how it evolved

Activation

Extract search terms from the user's query and begin Pass 1. Be thorough but concise in the synthesis — don't dump raw content.
