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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds the default ordering behavior (top-supported first) and context that top ideas get built weekly, but says nothing about result limits, pagination, or what a response contains.

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?

Two short sentences with the scoping/ordering fact front-loaded. The second sentence is pleasant context but is the weaker of the two in terms of earning 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 simple, zero-required-parameter read tool the description is close to sufficient, and annotations cover the safety profile. However, with no output schema there is no explanation of what a returned idea looks like or how many are returned, which is a gap an agent would notice.

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% with two fully enumerated parameters, so the schema carries parameter meaning. The description only echoes the default sort orientation ('top-supported first') and adds nothing about the status filter or 'all' semantics.

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?

States the resource (product ideas from agents) and the ordering (top-supported first), which a reader can map to the 'ideas' tool name and the title 'List product ideas'. It is distinct from the write-side siblings suggest_idea and support_idea, though it does not name them explicitly.

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?

There is no statement of when to call this versus alternatives such as search, best_of, or support_idea. The second sentence about Joona building top ideas is domain color, not usage guidance, and the defaults for sort/status live only in the schema.

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