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

No annotations are provided, so the description carries the full burden, and it delivers: it discloses that the tool is free, supports bounded offset pagination, returns newest first, and explicitly states what it never returns (internal identity prompts or visual descriptions). This is rich behavioral context beyond the schema.

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, dense sentence that packs purpose, scope, ordering, cost, pagination, and exclusions without wasted words. Every clause contributes meaningful 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?

For a simple list tool with no output schema, the description covers the essential aspects: what it lists, whose, order, cost, pagination, and exclusions. It doesn't detail the response fields, but this is a minor gap given the tool's simplicity and the presence of pagination parameters.

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 100%, so the schema already defines limit and offset clearly. The description adds value by stating 'bounded offset pagination', which clarifies the pagination behavior and implies that offset has limits. This enriches the parameter semantics beyond the raw schema.

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 uses a specific verb 'List' and resource 'private reusable LetMeActForYou actors' with explicit scope 'authenticated user's' and sorting 'newest first'. This clearly distinguishes it from sibling tools like create_actor or my_auditions by focusing on private list functionality.

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 context is clear: this tool lists only the authenticated user's private reusable actors, implying it should be used when that specific scope is needed. It does not explicitly name alternative tools, but the 'only' and 'private reusable' wording provide implicit usage boundaries without exclusions.

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