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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description restates 'Read-only' (no added credit) and adds only 'free', a minor cost signal. It doesn't disclose return shape beyond the topic list, but with annotations and an output schema present, a 3 is fair.

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?

Front-loaded with what the tool is, then the topics, then the usage discriminator, with no filler. Slightly dense in the middle clause, but 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?

For a zero-required-parameter docs-retrieval tool with annotations and an output schema, the description covers purpose, the option space, and when to invoke. Nothing essential is missing, though it could note the default topic behavior explicitly.

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 the parameter, and it does: it names all six enum values for 'topic' and glosses what several contain ('which tool and fields for a request', 'changes and the canvas', 'posting and monthly plans'). That adds real meaning beyond the bare enum in the schema.

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 makes clear this tool returns extended guidance notes on Clypmint and enumerates the six topic areas (overview, music, styles, editing, publishing, capabilities), so the resource is unambiguous. The verb is only implied ('Fuller notes on using Clypmint') rather than stated, and the name/title ('get_workflow' / 'Read current Clypmint workflows') is arguably more precise than the body, but the purpose is still identifiable.

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 gives an explicit when-to-use ('when a request is unusual') and an explicit when-not ('A normal request needs none of it: the tool descriptions are enough'). That is a genuinely discriminating routing rule an agent can apply without inspecting siblings.

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