Record one full conversation turn to today's journal.

You MUST pass the complete user message and your entire reply — no truncation, no summary, no "..." or "see above". If your reply is very long, pass the first part here then use memory_log_conversation_append() for the rest.

Args: user_message: The user's full message in this turn. agent_response: Your full reply (complete text, every paragraph). model: The model used for this response (e.g. "claude-4-opus"). code_changes: Optional. Files created/modified, e.g. "- src/foo.py (created)". title: Optional. One-line summary for this turn; if empty, derived from first line of user_message.

Append more text to the last Agent section in today's journal.

Use after memory_log_conversation() when your full reply did not fit in one call. Can be called multiple times; each chunk is appended to the same turn.

Args: agent_response_chunk: Next part of your reply to append (no truncation).

Search chat history for a keyword, returning full conversation turns.

Args: query: Text to search for (case-insensitive). since: Only search from this date onward (YYYY-MM-DD format). max_results: Max turns to return (0 = no limit).
