-]v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds no extra behavioral context, such as pagination, rate limits, or the meaning of 'voices'. Given the annotations carry the load, the description is neutral but not additive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence with no wasted words. It is appropriately minimal for a simple list operation, though it could potentially add a bit more context without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description does not hint at the return format (e.g., array of voice objects, pagination). For a straightforward read-only list, this may be acceptable, but the lack of any return or scope detail makes it only minimally complete. The annotations cover safety, but not response expectations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema provides 100% coverage for the single optional 'token' parameter, including its format and fallback to COMMONS_TOKEN. The description adds no additional semantic value beyond the schema, so the baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a clear verb ('list') and resource ('voices you follow'), making the purpose unambiguous. However, it does not differentiate itself from the sibling tool 'followed_feed', which could also list followed content, so it loses a point for missing that distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
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 versus alternatives. The description only states what it does, with no mention of context, prerequisites, or when to prefer it over related tools like 'followed_feed' or 'follow_voice'. This leaves the agent to infer usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
