TDQS

A3.9/5.0
Behavior3/5

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

Annotations already mark the tool as read-only and open-world. The description adds the useful behavioral note that results may be paginated and a cursor should be used. It does not disclose return format details or failure modes, but with annotations covering the safety profile, this is adequate.

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 no filler. The core action and resource are stated immediately, and the pagination instruction is a useful, non-redundant addition.

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

Completeness3/5

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

The tool has no output schema Synthesis attempted, so the description should explain what the returned list contains. It only says 'Returns a list' and mentions cursors, but does not describe fields, sorting, or how to interpret the results. The 12-parameter schema contains many generic/ignored fields, so the description could help by clarifying which parameters matter. It is acceptable but not complete.

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?

The input schema already describes the primary 'query' parameter with a clear description (search query text for Facebook ad library companies). The description's mention of 'company name' aligns with the schema but adds little beyond it. Many other parameters are documented as 'Ignored if this tool does not support it', so the schema carries the semantic burden.

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 clearly states the action ('Search'), the resource ('Facebook Ad Library companies / advertisers'), and the search method ('by name'). It distinguishes itself from sibling tools like facebook_adLibrary_ads_search_get by specifying companies/advertisers rather than ads.

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

Usage Guidelines4/5

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

The description gives clear context for when to use the tool: it accepts a company name and returns a paginated list. It does not explicitly name alternatives or exclusions, but the criteria are unambiguous and the pagination hint provides practical usage guidance.

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