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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is covered. The description adds the five scoring dimensions and points to a fuller external version, but says nothing about how the grade is returned or its scale. Moderate value beyond annotations.

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 sentences, front-loaded with the core purpose, and the dimension list is useful. The trailing marketing URL is somewhat extraneous but not harmful; overall efficient.

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?

With no output schema, the description should ideally explain the returned grade format or scale, which it does not. It is adequate given annotations cover safety, but the result shape is left unspecified.

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% with enums and explicit weights per parameter, so the schema does the heavy lifting. The description's list of dimensions mirrors the parameters but adds no syntax or meaning beyond what the schema already documents. Baseline 3 applies.

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 a specific verb ('Grade the risk') plus a precise resource ('pivoting upmarket to enterprise') and enumerates the five dimensions scored. This clearly distinguishes it from generic siblings like product_market_fit_scoring_grader or product_led_growth_feasibility_grader.

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?

No guidance on when to use this vs. the many other graders/planners in the sibling set, and no prerequisites or exclusions stated. The 'pivot upmarket' framing implies context but the agent must infer it.

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