list_worker_services

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

With no annotations and no output schema, the description carries the full burden of behavioral disclosure, but it only says 'List' and 'in an account.' It does not disclose pagination behavior, response shape, permissions required, or whether any filtering is applied, leaving significant behavioral details unstated.

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, direct sentence with no filler or redundant phrasing. It front-loads the action and resource clearly, making it appropriately concise for a simple list operation.

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 low complexity (one required parameter, no nested objects) and fully documented schema, the description is minimally adequate. However, the absence of an output schema and any mention of pagination or result contents leaves some gaps for an agent trying to predict the tool's full behavior.

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 input schema covers 100% of the single parameter, account_id, so the baseline is 3. The description adds some scope context ('in an account') but does not add meaning beyond what the schema already provides for the parameter itself.

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 states a specific verb ('List'), a resource ('Worker services'), and the scope ('in an account'), so it is clear about the core action. However, it does not distinguish this tool from closely named siblings like list_workers, list_worker_routes, or list_worker_secrets, so no sibling differentiation is provided.

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 gives no guidance on when to use this tool versus alternatives such as list_workers or get_worker_script. There is no mention of prerequisites, exclusions, or conditions that would help an agent choose this tool confidently.

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