list_registration_aliases

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false. The description adds behavioral context (case-insensitive substring filtering, pagination controls) beyond the annotations, but could be more explicit about result size or limitations. No contradiction with annotations.

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 extremely concise: a single sentence for purpose plus a brief bullet for arguments. Front-loaded with the core functionality. Every sentence earns its place.

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 annotations and existing output schema, the description covers the essential function and argument semantics. However, it lacks clarification on how this tool differs from similar siblings (e.g., list_aliases) and does not mention anything about authentication or result ordering, but overall it is sufficient for a simple list 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%, so the description must compensate. It explains 'alias_contains' as 'case-insensitive substring match' and groups 'limit, offset, fetch_all' as 'pagination controls'. These add meaning beyond the schema types and defaults, though more detail could be given.

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 'List currently registered aliases on the platform' with a specific verb and resource. However, it does not explicitly distinguish itself from siblings like 'list_aliases' or 'get_registration_alias', so it misses the top score.

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 versus alternatives, nor does it mention prerequisites or exclusions. It only lists arguments without usage context.

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