TDQS

A4.1/5.0

Scored across 79 tools

Disambiguation4/5

Tools are clearly distinguished by descriptions that explicitly separate DM vs group vs self variants and different receive methods. While there are many similar-sounding tools (e.g., receive_messages vs receive_direct vs get_unread), each has a distinct purpose and the descriptions provide unambiguous guidance.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern (send_message, list_groups, update_profile, get_conversation). Even longer names like submit_rate_limit_challenge adhere to the pattern. There are no mixed conventions or chaotic variations.

Tool Count2/5

With 79 tools, this is far beyond the typical well-scoped server (3-15). While each tool has a distinct purpose, the surface is enormous and could be consolidated (e.g., merging DM/group variants with a parameter). The sheer number makes it heavy and potentially overwhelming for agents.

Completeness5/5

The tool set covers virtually every aspect of Signal: messaging (text, attachments, stickers, polls, reactions, typing), groups, contacts, devices, profile, settings, local store management, scheduling, webhooks, security (PIN, identity), and number migration. No obvious gaps in the domain.
