A4.2/5.0

Scored across 81 tools

Disambiguation3/5

Each tool's description is exceptionally cross-referenced, but the surface is crowded with near-parallel variants that could be confused: send_message / send_group_message / send_attachment / send_group_attachment / send_note_to_self / send_sticker / send_group_sticker all mean 'send something', and delete_message / delete_group_message / admin_delete_message / delete_local_messages / clear_local_store / prune_store form a dense deletion cluster. The receive trio (receive_messages / receive_direct / get_unread) and the set_expiration_timer vs update_group(expiration_seconds) overlap add further selection burden. Boundaries are documented, but the agent must read carefully to pick correctly.

Naming Consistency5/5

Names follow a strictly consistent snake_case verb_noun pattern (list_contacts, send_group_message, update_group, terminate_poll, remove_device, prune_store). Read and write operations are clearly signaled by their verb prefixes throughout all 81 tools with no mixed conventions.

Tool Count2/5

81 tools is far beyond a comfortable surface for an agent. While the domain is genuinely broad (messaging, groups, devices, account, stickers, polls, stories, scheduling, local store), many tools are one-shot admin operations (set_pin, submit_rate_limit_challenge, finish_change_number, upload_sticker_pack) or parameterizable variants that could be collapsed, making the set heavy and hard to navigate.

Completeness5/5

Coverage is exhaustive: full messaging lifecycle (send/edit/react/pin/delete/read-receipt), group and membership administration, contacts, profiles, devices, identity/trust, polls, stories, stickers, scheduling, and local-store import/export/prune management. There are essentially no dead ends for the stated purpose of controlling a full Signal account.
