list_docsets

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

With no annotations, the description must carry the burden of disclosing behavioral traits. It implies a read-only list operation and mentions 'additional metadata' but does not specify what 'detailed information' includes, nor does it address potential prerequisites (e.g., whether docsets need to be initialized via init_docset) or return structure. This leaves key behavioral aspects undisclosed, but the simple nature of listing with no params mitigates the gap.

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, consisting of two sentences. The first sentence states the core function, and the second sentence provides a relevant usage note about search_docs. Every sentence earns its place with no redundancy or filler.

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?

While the tool is simple (0 params, no output schema), the description is vague about what 'detailed information' includes. An agent would need to invoke the tool to discover the exact metadata, which is a gap since the description is the only source of return-value information. The note about search_docs helps clarify positioning, but the lack of detail about the output makes it incomplete for an agent deciding if this tool meets its needs.

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?

The tool has zero parameters, so the schema is empty. The description does not need to explain parameters, and with no parameters, there is nothing to clarify. According to the rubric, 0 params yields a baseline of 4, which is appropriate here—the description adds no parameter semantics, but none are required.

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 'all available documentation sets (docsets)' with 'detailed information' as the purpose. It distinguishes from the sibling tool search_docs by explicitly noting that it provides additional metadata, making its unique role clear.

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 explicit guidance on when to use this tool versus the search_docs sibling: 'The search_docs tool already shows available docsets in its description, so this tool is mainly for getting additional metadata.' This tells the agent when to choose list_docsets over the alternative, effectively serving as a clear usage directive.

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