Conversation History Search

Search through Claude Code conversation history to find relevant past discussions.

When to Use

Finding previous discussions about a topic
Recalling past decisions or solutions
Getting context from earlier conversations
Looking up how something was implemented before

How to Search

Run the search script from the services directory:

cd ~/.claude/services
python conversation-search.py "search term"

Search Options

Option	Description
`--list-sessions`, `-l`	List all sessions with metadata
`--session ID`, `-s`	Filter to specific session (partial match)
`--context N`, `-c`	Show N messages before/after (default: 3)
`--max N`, `-m`	Maximum results (default: 20)
`--verbose`, `-v`	Show context messages
`--full`, `-f`	Show full message content

Examples

# List all available sessions
python conversation-search.py --list-sessions

# Basic search
python conversation-search.py "bulk upload"

# Regex search
python conversation-search.py "context.*percent|usage.*%"

# Search specific session with full output
python conversation-search.py "statusline" --session 6cabef43 --full

# Get more context around matches
python conversation-search.py "error" --context 5 --verbose --max 3

Output Modes

Default: Preview snippet (50 chars before, 100 after match)
Verbose (-v): Adds surrounding message context
Full (-f): Complete message content

Token Efficiency

The search runs externally, so searching costs 0 tokens. Only the returned results consume context.
