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

Annotations already declare read-only, idempotent, non-destructive, and closed-world behavior. The description adds useful context beyond annotations by saying the catalog is live, paginated, and covers existing app business modules rather than a static lease CRUD list.

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 front-loaded sentences with no filler. The first sentence states the action and filters; the second clarifies catalog scope and pagination.

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 five-parameter discovery tool with no output schema and no schema descriptions, the definition gives the high-level scope and pagination behavior but leaves parameter semantics and result shape largely inferred. It is minimally adequate but not fully complete.

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%, so the description must carry parameter meaning. It maps 'module', 'method', and 'words' to filtering, and 'paginated' implies page/pageSize, but it does not explain page defaults, pageSize limits, or that method is an enum.

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 clear verb and resource: it searches the live organization API catalog, filtered by module, method, or words. It distinguishes itself from a static lease CRUD list, but does not explicitly name relevant siblings such as describe_operation, list_modules, or execute_read.

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 'paginated discovery' implies this is used to browse or discover available API operations, but there is no explicit guidance on when to use it instead of describe_operation, list_modules, or execute_read. The agent must infer the discovery use case from the purpose statement.

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