list_personas

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

No annotations provided; description adds only an admin restriction. It contradicts the schema by marking caller_agent_id as required when schema shows it's optional. No mention of read-only behavior or error cases.

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?

Description is brief and structured with Args and Returns. However, it mixes Japanese and English and could be more concise by removing redundancy.

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 list tool, description covers purpose, admin constraint, and return fields (success, personas, count). No output schema provided, but return structure is described sufficiently.

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?

Schema coverage is 0%, so description must compensate. It describes caller_agent_id as 'required' but schema shows optional, creating confusion. No additional semantics beyond the name.

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 clearly states 'Get list of available personas' and specifies admin-only use. It uses a specific verb and resource, distinguishing it from sibling tools like get_optimal_persona.

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 mentions 'Admin only' which provides a usage condition, but lacks explicit when-not-to-use or alternative tools. No guidance on whether this should be called before other operations.

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