The tools are mostly distinct: list_sessions and get_session clearly separate listing from detail retrieval. However, create_session and create_session_from_issue overlap in purpose, with the latter being a specialization, which could cause minor selection ambiguity.

All tool names follow a consistent verb_noun pattern: create, list, get, create. Even the longer 'create_session_from_issue' maintains the convention with a clear prepositional modifier. There is no mixing of styles or vague verbs.

With exactly 4 tools, the server is well-scoped for its purpose of managing Jules coding sessions. Each tool covers a distinct core operation without redundancy, making the count feel appropriate and not overwhelming.

The tool surface covers session creation (two variants), listing, and retrieval, which handles the primary lifecycle needs. However, it lacks explicit update or delete/cancel operations, which are minor gaps that could be worked around but are not covered.
