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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'List all available...' without explaining the impact of the 'format' parameter, return structure, pagination, or any side effects. The tool appears read-only, but this is not explicitly stated, and the behavior of the optional parameter is left opaque.

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 concise, just two sentences. The first sentence clearly states the tool's purpose, and the second sentence adds a note about filtering. It is not verbose, though the second sentence is somewhat vague and could be more specific.

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 absence of an output schema and no annotation support, the description should convey what 'details' are returned and how the 'format' parameter affects them. It fails to do so, leaving the agent with incomplete information for a simple but non-trivial listing tool.

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 description coverage is 0%, and the description does not mention the 'format' parameter at all. The statement about filtering does not connect to how the parameter works, leaving the agent with no guidance on parameter syntax, values, or default behavior beyond the schema's type and default.

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 action ('List') and the resource ('service catalog repositories') with the added detail 'with their details'. This distinguishes it from sibling list tools like CYCLOID_BLUEPRINT_LIST and CYCLOID_PIPELINE_LIST, making the purpose unambiguous.

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 phrase 'The LLM can filter the results based on user requirements' implies use cases where the user needs to find repositories, but it does not explicitly mention when not to use this tool or provide alternatives. It relies on the tool's name and sibling context for differentiation, so guidance is only implied.

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