TDQS

D1.8/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=false. The description adds nothing beyond that: it omits the async task model, the polling behavior, the public-URL/file-ID requirement, and any cost or latency context.

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

Conciseness2/5

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

Four sentences of pure marketing copy with zero technical content; nothing is front-loaded that helps an agent invoke the tool. The length is wasted rather than excessive.

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

Completeness1/5

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

For a tool with six mutually exclusive input variants, an async task model, and a nested request object, the description provides no invocation guidance at all. An agent cannot determine which schema branch to use or how the task lifecycle works from this text.

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

Parameters1/5

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

Schema description coverage is only 50% and the description compensates for none of it. It never explains src_file_url, ref_file_url, hair_color, template_id, or polling, and gives no clue about which of the six anyOf variants to use. Hairstyle categories (curly, long, buzz cut) are unrelated to any parameter.

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

Purpose2/5

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

The description restates the tool name in marketing terms ('AI-powered hair changer', 'try a wide variety of hairstyles') without specifying the mechanics (src/ref image transformation). It offers no differentiation from siblings like AI-Hair-Color-Virtual-Try-On, AI-Hair-Extension-Virtual-Try-On, or the -Templates variant.

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

Usage Guidelines2/5

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

There is no when-to-use guidance, no mention of the alternative template-based variant or the file upload API, and no prerequisites. 'Find your ideal hairstyle now!' is promotional, not operational guidance.

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