Memory Search - Cross-Session Context

Overview

Search through stored observations from past Claude Code sessions. Use this skill when the user asks about:

• "What did we do last session?"
• "How did we implement X before?"
• "What bugs did we fix recently?"
• "What decisions were made about Y?"
• "Show me recent work on this project"

How to Use

Run the search command to query the context memory database:

python3 "$CLAUDE_PROJECT_DIR/.claude/memory/context_memory.py" search "<query>"

Common Queries

Recent activity:

python3 "$CLAUDE_PROJECT_DIR/.claude/memory/context_memory.py" recent

Search for specific topic:

python3 "$CLAUDE_PROJECT_DIR/.claude/memory/context_memory.py" search "authentication"

Get statistics:

python3 "$CLAUDE_PROJECT_DIR/.claude/memory/context_memory.py" stats

Get full context for current branch:

python3 "$CLAUDE_PROJECT_DIR/.claude/memory/context_memory.py" context "branch-name"

Observation Types

The memory stores these types of observations:

Database Location

The context memory is stored at: ~/.claude/context_memory.duckdb

Response Format

When presenting search results:

1. Group by type (decisions, bugfixes, features, etc.)
2. Show most recent first
3. Include timestamp and branch if relevant
4. Summarize rather than dump raw data

Example Response

"Based on context memory, here's what happened:

Recent Decisions:

• [2 days ago] Chose DuckDB over SQLite + Chroma for context storage
• [3 days ago] Adopted tiered context injection strategy

Recent Bugfixes:

• [Yesterday] Fixed authentication timeout in API routes

Recent Features:

• [Today] Implemented context memory hooks"
