TDQS

A4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, covering the safety profile. The description adds useful context beyond annotations: the required 'user.activity' scope, the caveat that data may not always be available ('where available'), and a medical disclaimer. This provides meaningful behavioral insight without contradicting the 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?

The description is extremely concise, consisting of three short sentences that front-load the primary purpose, then add the scope requirement and a disclaimer. There is zero fluff; every sentence earns its place.

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 and high schema coverage, the description does not need to explain return formats or parameters. It covers the essential purpose, scope prerequisite, and data availability caveat. It lacks explicit sibling differentiation, but that is minor given the schema's richness and annotations.

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 88%, so the schema already documents all parameters thoroughly (e.g., 'after' and 'before' explain conversion to epoch). The tool description adds no parameter-level information, which is acceptable given the high schema coverage. Baseline 3 is appropriate.

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

Purpose5/5

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

The description states a specific verb ('List'), resource ('detailed Withings sleep data'), and a condition ('where available'). It clearly distinguishes from the sibling tool withings_list_sleep_summary by emphasizing 'detailed', making the tool's purpose unambiguous.

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

Usage Guidelines3/5

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

The description implies usage through the phrase 'where available' and mentions a required scope, but it does not explicitly state when to use this tool over alternatives like withings_list_sleep_summary or when not to use it. No exclusion or alternative routing is provided.

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