protect_list_sirens

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

The description goes beyond the readOnlyHint annotation by detailing the return structure (array with specific fields) and explicitly warns that additional device-specific fields are unverified due to lack of instances on the reference console. This provides critical behavioral context for the agent.

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 two sentences, front-loaded with the core action, and directly provides return structure and caveats. Every word adds value; no filler or 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?

Given no parameters and existing annotations (readOnlyHint, destructiveHint) and an output schema, the description covers the essential behavioral detail (return fields and their reliability) and addresses potential pitfalls (unverified fields). It is fully adequate for an agent to use correctly.

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?

There are zero parameters, so baseline is 4 per guidelines. The schema coverage is 100% and the description does not need to add parameter details. No deduction needed.

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 the verb 'list' and the resource 'sirens', making the purpose obvious. However, it does not explicitly differentiate from the sibling tool 'protect_get_siren', which retrieves a single siren. The distinction is implied by 'list' vs 'get', but not stated.

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 provides no guidance on when to use this tool over siblings like 'protect_get_siren', nor does it mention any prerequisites or exclusions. Usage is only implied by the purpose, but no explicit context is given.

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