Annotations already declare readOnlyHint, idempotentHint, and non-destructive. Description adds pagination and return fields, but does not address openWorldHint (results may change) or provide additional behavioral context beyond 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?
Single sentence, front-loaded with action and resource, no wasted words.
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 output schema, annotations, and sibling tools, the description covers the essential aspects. Missing are details on ordering, page size, or error behavior, but these are not critical for basic usage.
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?
With 0% schema description coverage, the description compensates partially by mentioning pagination, implying the 'page' parameter controls page number. 'username' is clear. However, no format details or defaults are 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?
Description clearly states the verb 'List', the resource 'completed kata for a username', and distinguishes from siblings like 'user' and 'user_authored'. It also specifies pagination and return fields.
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 does not explicitly state when to use or when not to use this tool versus alternatives. The context implies it's for completed kata, but no guidance on exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
