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

The annotations already declare openWorldHint=true, destructiveHint=false and idempotentHint=false; the description usefully adds that no generation, publishing, or account mutation occurs and that results come back as scores, evidence, fix packs, and resources. It never explains why readOnlyHint is false, i.e. whether an audit record is persisted or how repeated calls behave, which is the main behavioral question an agent would still have.

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 sentences, front-loaded with the core action and scope, then the return shape, then the non-goals and a docs link. No sentence is redundant.

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 only two parameters, no output schema, and a thin annotation set, the description covers the return categories and the safety scope well. It falls short on the optional 'checks' default behavior and on what side effects justify readOnlyHint=false, both of which an agent needs before invoking it.

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 0%, so the description must carry the meaning. It clarifies that 'url' must be public and enumerates the three check categories matching the 'checks' enum, but it does not say what happens when 'checks' is omitted (only 'url' is required) or that at most three checks can be selected.

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 and resource ('Audit a public URL') plus the scope of the audit ('launch, technical, and agent-readiness checks') and what it returns. It does not, however, differentiate itself from the very similar sibling 'assess_launch' or from 'reassess_launch' / 'verify_launch_audit', so an agent cannot pick between them from the text alone.

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?

Usage is only implied: audit a public URL. The exclusions ('No account actions, provider generation, or publishing') describe what the tool will not do rather than when to call it, and no alternative such as assess_launch is named. Prerequisites (the URL must be publicly reachable) are only hinted at by the word 'public'.

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