B3/5.0
Behavior3/5

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

Annotations include destructiveHint: false, idempotentHint: true, and readOnlyHint: false. The description does not contradict these, but it adds little beyond the schema: it says 'Unfollow a voice you previously followed,' which implies mutating state but doesn't specify what happens on unfollow (e.g., reversible, updates feeds, permissions needed). With annotations present, the bar is lower; description adds minimal context beyond what's already implied, so a 3 is reasonable.

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 a single sentence that is efficient and front-loaded with the action and resource. There is no wasted wording.

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 a simple interface (one required parameter, no enums, no output schema, no nested objects) and complete schema descriptions. The description is minimal but sufficient for a basic action; it doesn't need to explain return values since there's no output schema. However, it lacks guidance on preconditions (e.g., must have followed first) and effects, which could improve completeness for an agent, but given the simplicity, a 3 is fair.

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 coverage is 100% (both token and voice_id have descriptions). The description adds no extra meaning beyond the schema; it doesn't clarify formats or defaults beyond what's already in the schema. Since the schema documents the parameters well, a baseline of 3 is appropriate.

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

Purpose3/5

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

The description clearly states the action (unfollow) and the resource (a voice), which is a specific verb and resource. However, it does not distinguish it from sibling tools like 'leave_interest' or 'unendorse_interest,' which are similar unfollow-type operations, so it lacks explicit differentiation.

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 guidance on when to use this tool vs. alternatives like 'follow_voice' or other unfollow actions. The description implies usage (unfollow a voice you previously followed) but provides no conditions, prerequisites, or exclusions, leaving the agent to infer when it's appropriate.

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