Scored across 5 tools
Each tool has a clearly distinct purpose: command_chains finds related sequences, failed_commands lists failures, recent_in_dir shows commands in a directory, reindex manages the index, and search_history does full-text search. There is no overlap.
Tool names use snake_case but vary in pattern: command_chains and recent_in_dir are noun phrases, failed_commands is adjective+noun, while reindex and search_history are verbs. This mixing reduces predictability.
With 5 tools, the server is well-scoped for querying and managing terminal history. Each tool serves a specific need without being excessive or insufficient.
The tool surface covers major query types (search, chains, failures, directory context) and index maintenance. A minor gap is the lack of a tool to directly retrieve a single command by ID, but it's not essential for common use cases.
