Discover Influencers

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

Annotations already declare readOnlyHint, destructiveHint, idempotentHint, openWorldHint. The description adds valuable behavioral context: 'Free plans see up to 3 results; paid plans get full access.' This plan limitation is not in structured fields and helps the agent understand constraints.

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 and well-structured: a clear purpose sentence, a plan limitation note, then a bulleted list of parameters. Every sentence adds value, and the most important information (search + filters) is front-loaded.

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 15 parameters with full schema coverage and no output schema, the description explains all parameters and adds plan context. However, the return value ('List of influencer profiles with metrics') is vague; more detail on output fields would improve completeness. Still, it is sufficient for most use cases.

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%, but the description adds meaning beyond the schema by providing examples (e.g., categories: ['tech', 'gaming']), explicit thresholds for engagement_tier (e.g., 'high' >5%), and clarification of sort_by options. This helps the agent select appropriate values.

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 explicitly states the tool searches the InfluIQ discovery database for influencers matching criteria, with specific verb 'search' and resource 'influencers'. It lists many filters, distinguishing it from sibling tools like get_discovery_profile (single profile) or get_discovery_filters (available filters).

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 no guidance on when to use this tool versus alternatives. It does not mention exclusions or suggest when not to use it. For example, it does not direct users to get_discovery_profile for a specific influencer.

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