A4.2/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the description doesn't need to restate safety. It adds value by specifying that it returns 'public' data and includes 'visible biography and counts', which gives the agent a sense of what to expect. It could go further by describing rate limits or error conditions, but it's solid.

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 sentences, front-loaded with the core function and followed by a clear routing hint to the sibling tool. Every sentence earns its place with no redundancy.

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?

Given the simple schema (one parameter) and the presence of an output schema (which means return values needn't be explained), the description is nearly complete. It could mention pagination or rate limiting, but for a profile lookup tool with annotations covering safety, it's sufficient.

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 schema has 100% description coverage for the single parameter ('username'), so the schema already documents it fully. The description doesn't add anything beyond the schema, which is acceptable baseline performance.

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 ('Returns') and resource ('public profile metadata for a Threads username'), and it clarifies the scope of the returned fields ('visible biography and counts'). It also distinguishes itself from the sibling threads_post by explicitly naming it.

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 a clear usage context ('Use threads_post to retrieve a public Threads post'), which implies that this tool is for profile metadata and the sibling is for posts. However, it doesn't explicitly state when not to use this tool or list other alternatives like threads_user_posts, so it falls short of a full 5.

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