TDQS

A4/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=false, covering the safety profile. The description adds that results are ordered by message volume and split across people/groups/platforms, but this is essentially return-content detail also covered by the output schema, so it adds limited behavioral context beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with zero waste, and the routing constraint is front-loaded in the second line. Nothing redundant or padded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need not be explained, and annotations cover safety. The description supplies purpose and usage context adequately, though the meaning of 'sources' relies partly on the annotation title ('List people and chats').

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so 'name' (partial match, like participant) and 'limit' (default 30, max 200) are already fully documented in the schema. The description adds no parameter detail beyond it, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description defines what list_sources returns: the most-messaged people with their chats, busiest group chats, and platforms. It conveys the resource concretely, though it is phrased as a label ('Who is in the archive') rather than a clean verb+resource, and it doesn't explicitly contrast against other listing-type siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states when the tool is NOT needed ('Not needed before searching') and names the alternative that handles the case instead (search_memoreei finds people by name or number itself). This is explicit routing guidance an agent can act on directly.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
