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

No annotations provided, so description bears full burden. Describes data source (users paying $1+) and result fields, but does not explicitly state the tool is read-only, disclose update frequency, or mention any side effects. Adequate but could be more upfront about safety.

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?

Description is a single paragraph of moderate length. It is clear and front-loaded with purpose. Slightly verbose with example companies but no wasted sentences. Could be tightened slightly.

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 the tool has 2 optional parameters and no output schema, the description covers the return structure and use cases. Lacks mention of default limit value or category optionality, but schema already covers that. Adequately complete for a simple query tool.

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 coverage is 100%, baseline 3. Description adds value by listing result fields (title, company, supporters, revenue) which helps the agent understand what to expect, and includes the price cue ($1+). Does not repeat schema descriptions verbatim.

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 uses specific verb 'aggregated' and resource 'top consumer demands', clearly stating it shows demands with title, company, supporters, revenue. Distinguishes from sibling tools as no other tool in the list relates to consumer demands or trending topics.

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?

Explicitly suggests use cases: surface unmet market needs, pre-product validation, consumer insights. However, does not mention when not to use it or alternative tools, though sibling tools are not close substitutes.

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