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

With no annotations, the description carries the full burden. It explains that omitting the optional parameter returns everything, and that the enum values correspond to documentation sections. However, it largely echoes the schema description and does not disclose other behaviors like error handling or response format, which is acceptable for a straightforward read tool but adds minimal extra context.

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 a single, efficient sentence that front-loads the core purpose and then immediately explains the optional parameter behavior. Every word earns its place with no redundancy.

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 tool with one optional parameter and no output schema, the description is fully sufficient. It tells the agent exactly what the tool returns, how to request a section or the whole document, and the valid values are in the schema. No additional context is needed.

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 100%, so the schema already documents the single parameter fully. The description adds no new parameter semantics beyond restating the omit behavior already present in the schema, so the baseline of 3 applies.

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 tool returns machine documentation, either one of the named sections or the whole document. It uses a specific verb ('get') and resource ('docs'), and the listed sections distinguish it from all sibling tools, which handle tasks/destinations instead.

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?

It provides explicit usage instruction: omit the 'section' parameter to retrieve the full document, or specify a section for a targeted read. There are no sibling documentation tools, so no need for alternative routing, but it does not explicitly state when to use this tool versus others, though it is self-evident.

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