get_optimal_persona

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

No annotations provided. Description mentions admin-only authorization and returns success/persona. Does not disclose side effects or state changes; acceptable for a retrieval tool.

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?

Short and to the point, with key sections: purpose, admin note, args, returns. Slight redundancy with line breaks but overall efficient.

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?

Covers purpose, admin restriction, arg meanings, and return shape. However, the arg description error (caller_agent_id required) indicates incompleteness. Output schema exists so return details are less critical.

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?

Description adds minimal meaning: task_description as 'description of the task'. But for caller_agent_id, it says 'required' which contradicts the schema where it's optional with default null. This is misleading and reduces value.

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?

Description states 'Get the optimal persona for the task' with a specific verb and resource, and the parameter 'task_description' indicates input. It distinguishes from sibling 'list_personas' which lists all personas, implying this selects one.

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?

Informs that only Admin can use it, providing a usage condition. Does not explicitly state when to use versus alternatives like list_personas, or when not to use.

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