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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description's useful addition is the word 'hypotheses,' signalling speculative output that should be validated rather than treated as fact; beyond that it adds no return-format, latency, or rate-limit 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?

A single tight sentence with the action and output front-loaded and no filler. It is efficient, though the trailing 'using the buying roles of your sector' is the only clause doing extra work.

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 read-only hypothesis generator with full schema coverage and no output schema, the definition is minimally adequate. It does not tell the agent what the generated hypotheses look like or how to consume them, which would matter for a multi-sibling analytical workflow.

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 all six parameters, including the enum and its neutral-fallback behavior, are fully documented in the schema. The description only loosely gestures at 'product context' and 'buying roles of your sector,' adding no syntax or meaning beyond 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 states a specific verb ('Generate') and a concrete output ('champion, economic buyer and technical influencer hypotheses') drawn from 'your product context' via 'the buying roles of your sector.' This clearly separates it from generic analysis tools, but it never names or contrasts with any sibling like impact_full_audit or impact_pinpoint_value.

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 gives no when-to-use guidance, no prerequisites, and no indication of which sibling to prefer for related tasks. The phrase 'from your product context' hints at required input but is not framed as a usage condition.

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