recall

借助 FTS5 和 Chroma 进行语义记忆的快速召回。每当用户询问过往事件、主题或对话时，或者当历史背景能够为回答增添深度与广度时，此功能都应被主动调用。触发词：记住、我们什么时候……、我们聊了什么、上次、之前、先前、那次对话、那时、历史、过去、回忆。

description: Semantic memory recall using FTS5 and Chroma. Use PROACTIVELY whenever the user asks about past events, themes, conversations, or when historical context would enrich a response. Trigger words: remember, when did we, what did we talk about, last time, before, previously, that conversation, that time, history, past, recall.

Semantic Memory Recall

This skill searches through semantic memory indexes for associative recall of past conversations, themes, and context.

When to Use This Skill

Use proactively when:

  • •User asks about past conversations or events
  • •User references "that time when..." or "remember when..."
  • •Historical context would enrich your response
  • •User asks about themes discussed previously
  • •You need to recall what was said about a topic

Two Memory Systems

1. SQLite FTS5 (Keyword Search)

Fast keyword matching with BM25 ranking.

bash
~/.claude-mind/system/bin/memory-index search "query" [limit]

Best for: Specific terms, names, dates, exact phrases

2. Chroma Vector Database (Semantic Search)

Embedding-based similarity search - finds related content even with different wording.

bash
~/.claude-mind/system/bin/chroma-query "query" [n_results]

Best for: Themes, concepts, "conversations like X", finding related discussions

Search Strategy

  1. •

    Determine query type:

    • •Specific term/name/date → Use FTS5 first
    • •Theme/concept/vague reference → Use Chroma first
    • •Comprehensive search → Use both
  2. •

    Run searches:

bash
# Keyword search (FTS5)
~/.claude-mind/system/bin/memory-index search "coffee shops" 10

# Semantic search (Chroma)
~/.claude-mind/system/bin/chroma-query "conversations about morning routines" 5

# For comprehensive recall, run both
~/.claude-mind/system/bin/memory-index search "project planning" 5
~/.claude-mind/system/bin/chroma-query "discussions about work priorities and goals" 5
  1. •Synthesize results: Combine findings from both systems, noting dates and context.

Output Format

When presenting recalled memories:

  • •Lead with the most relevant finding
  • •Include dates to establish timeline
  • •Quote key excerpts when helpful
  • •Note which system found each result (keyword vs semantic match)
  • •Connect findings to the user's current question

Examples

User: "What did we talk about when I was at that coffee shop?"

bash
# Semantic search for coffee shop conversations
~/.claude-mind/system/bin/chroma-query "coffee shop conversation" 5

# Keyword backup
~/.claude-mind/system/bin/memory-index search "coffee" 5

User: "Remember that discussion about Q1 planning?"

bash
# Semantic for the theme
~/.claude-mind/system/bin/chroma-query "Q1 planning discussion goals priorities" 5

# Keyword for specifics
~/.claude-mind/system/bin/memory-index search "Q1" 5

User: "What have I said about my work situation?"

bash
# Broad semantic search
~/.claude-mind/system/bin/chroma-query "work job career situation feelings" 10

# Follow up with specific terms found
~/.claude-mind/system/bin/memory-index search "specific_term_found" 5

Data Sources

Both systems index:

  • •Episode logs (daily conversation records)
  • •Reflections (dream cycle outputs)
  • •Learnings
  • •Observations
  • •Decisions
  • •Person profiles

Results include source type and date for context.
