Category & Scope

Tools & Capabilities Breakdown

Memocall Tools (5)

list_sessions

List your recent Claude Code conversations across ALL projects, grouped by project directory. Use this to answer 'what sessions have I worked on recently?' or to find a past session before loading it. Returns each session's title, date, turn count, and id.

search_sessions

Search your past Claude Code conversations (across all projects) by keyword — matches session titles, first messages, and project paths. Use when the user refers to a past conversation by topic (e.g. 'the session where we set up the license system'). Returns matching sessions with their ids.

load_session

Load the context of a past Claude Code conversation as compact Markdown (human turns, collapsed tool-call summaries, and assistant replies — tool outputs are elided). Provide either a session `id` (from list_sessions/search_sessions) or a free-text `query` to find it. Use this to pull a previous conversation's context into the current session. For a very large session, either pass `turns` to load a specific window (turn numbers come from session_outline), or prefer session_outline / search_in_session.

session_outline

Get a quick MAP of a past Claude Code conversation: the numbered list of the user's prompts, one line each. Very cheap even for huge sessions. Use this to see what a session covered, or to find which turn numbers to then load with load_session's `turns`. Identify the session by `id` or free-text `query`.
