feat(session_search): add recent sessions mode when query is omitted#2533
Conversation
When session_search is called without a query (or with an empty query), it now returns metadata for the most recent sessions instead of erroring. This lets the agent quickly see what was worked on recently without needing specific keywords. Returns for each session: session_id, title, source, started_at, last_active, message_count, preview (first user message). Zero LLM cost — pure DB query. Current session lineage and child delegation sessions are excluded. The agent can then keyword-search specific sessions if it needs deeper context from any of them.

Summary
When
session_searchis called without a query, it now returns metadata for recent sessions instead of erroring. The agent can quickly see what was worked on recently without needing specific keywords.How it works
Zero LLM cost for the recent mode — pure SQLite query via existing
list_sessions_rich. Current session lineage and child delegation sessions are excluded.Example output
{ "mode": "recent", "results": [ {"session_id": "20260321_...", "title": "PR review session", "preview": "Lets do 2264", "message_count": 47, ...}, {"session_id": "20260320_...", "title": null, "preview": "Can you check the ATM10 server?", "message_count": 12, ...} ] }The agent can then keyword-search specific sessions if it needs deeper context.
