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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that validation involves criterion coverage, checker compatibility, and creator acceptance before funding, but it does not describe what happens when a plan fails validation or what the 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?

Three short sentences, with the core purpose front-loaded and no filler. The phrase 'the creator must accept the meaning' is slightly opaque, but each sentence carries useful information.

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 validation tool with a nested object parameter and no output schema, the description omits what a successful or failed validation returns and how errors are surfaced. It does point to find_verification_checks for the input schema, which partially compensates, but the behavioral outcome remains underspecified.

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?

The input schema provides essentially no information about the required `plan` object (0% description coverage, nested object). The description compensates by directing the agent to find_verification_checks for the plan schema, which is critical, though it does not enumerate the plan's internal fields or required keys directly.

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 (validate) and two concrete validation targets: complete criterion coverage and checker compatibility. It is clearly about verification plans, though it does not explicitly contrast itself with siblings like run_verification_checks or get_verification_run.

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?

It provides an actionable prerequisite—fetch the plan schema from find_verification_checks—and a workflow ordering constraint: the creator must accept the meaning before funding. It lacks explicit when-not-to-use guidance or a direct comparison to run_verification_checks.

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