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

The description explains post-call semantics well (what counts_as_verified means and which statuses yield false), which is genuine value beyond the annotations. But 'file a claim' describes creating/recording state while the annotations declare readOnlyHint=true, a direct tension about side effects that the description never reconciles. It also says nothing about the cost of the openWorld verification call, idempotency, or failure behavior.

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 purpose and template list are front-loaded in the first sentence, followed by the return shape and then the status semantics, which is a sensible order with no filler. Minor deduction for opaque internal codes ('dcl-1 / dp-c1') that occupy space without telling an agent anything actionable.

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 24-parameter, open-world tool with no output schema and no schema descriptions, the description covers the template choice and the verification outcome semantics but leaves the majority of inputs undocumented. An agent would have to guess how expect, authz_ref, contains/target_contains, or recheck interact with each template before it could call this safely.

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% across 24 parameters, so the description carries the full burden and mostly does not: only the template enum values are echoed (already in the schema), while expect, pin_id, recheck, wait_for_propagation_s, tls_cert, authz_ref, json_fields, visibility and the rest are entirely unexplained. The status-tier explanation describes the response, not the inputs, so an agent cannot tell which parameters matter for which template.

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 names a specific verb and resource ('file and verify a claim in one call') and enumerates the four template values (static_page, redirect, app_route, api_health), so an agent knows what it produces. It does not explicitly distinguish itself from the close siblings submit_deploy_claim, submit_claim and verify_claim, leaving the 'in one call' phrasing as the only differentiation.

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 opening clause 'After a deploy' gives the situational trigger for using this tool, which is real guidance. However, there is no statement of when NOT to use it and no named alternative (e.g. use submit_claim + verify_claim separately when you have no template), so selection between the four sibling claim tools is left to inference.

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