list_personas

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

No annotations are provided, so the description must supply behavioral context. It implies a read-only operation via 'list', but does not explicitly state it is non-destructive, mention authentication needs, or describe response format. While adequate for a simple list, more detail would improve transparency.

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, compact sentence that includes the verb, resource, scope, and returned fields. Every part is useful and there is no extraneous information.

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?

Given the tool's simplicity (no parameters, no output schema), the description provides essential information: what it does, what it returns, and context about personas. It could mention pagination or response structure, but it is complete enough for basic usage.

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 tool has zero parameters, and schema coverage is 100%. With no parameters to explain, the description does not need to add parameter guidance. Baseline is 4, and the brief clarification of what 'persona' means is a bonus.

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 clearly states it lists all personas, defines what a persona is (an agent's character, 1:1 with the agent), and specifies the returned fields (id, name, status, version). This distinguishes it from siblings like list_deleted_personas.

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 does not explicitly provide when-to-use or when-not-to-use guidance. It implies usage for active personas but does not mention alternatives like list_deleted_personas for deleted ones. The distinction relies on the tool name rather than explicit instruction.

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