AI Presenter persona status

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

The description states 'CAPABILITY: read — side-effect-free', which restates what annotations already provide via readOnlyHint and destructiveHint. It adds no new behavioral context (e.g., response format, error handling, authorization). No contradiction, but fails to add value beyond structured fields.

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?

Two concise sentences, front-loaded with the action. Zero waste; every word serves purpose.

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?

For a simple one-parameter fetch tool with annotations covering safety, the description is adequate. It states the purpose and side-effect-free nature. The title 'persona status' implies the return is status-related, though the description does not explicitly define the response, which is acceptable given no output schema.

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 single parameter personaId is implicitly described as the id of the persona to fetch. However, since schema description coverage is 0%, the description must compensate but only minimally does so—no format, examples, or additional context are provided.

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 'Fetch one AI Presenter persona by id' uses a specific verb (fetch), identifies the resource (persona), and notes the identifier. This distinguishes it clearly from siblings like persona_list (list all) and persona_create (create).

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?

The description implies usage: when you need a single persona's details by id. However, it does not explicitly mention alternatives or exclusions, such as using persona_list for multiple personas or persona_create for creation. So guidance is implied, not explicit.

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