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

Annotations already establish readOnlyHint, idempotentHint, and non-destructiveness, so the safety profile is covered. The description adds genuinely new context beyond the annotations: credential handling (never in URLs, never echoed in errors) and the dual auth path (argument or Authorization header), which is valuable operational detail for a tool taking a secret.

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 compact sentences, front-loaded with the core action and scope before the auth mechanics. Every sentence carries weight, though the credential sentence is somewhat dense and could be split for readability.

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 does not indicate what a readiness result looks like (pass/fail per P0-P4, evidence details), which an agent would want. It does cover the essential action, scope, and auth, so it is adequate but not fully complete for a verification tool.

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 only 33%: only 'credential' carries a schema description, and the description usefully reinforces how to supply it. 'slug' and 'version_id' remain undocumented in both the schema and the description, so the description compensates for the coverage gap only partially.

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 gives a specific verb ('Recheck'), a concrete resource ('P0-P4 evidence'), and a scoping constraint ('for your exact version without publishing'). This distinguishes it from write-oriented siblings like release_flow and publish_game, though it never names an alternative explicitly.

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 phrase 'without publishing' implies the use case: verify readiness before a release rather than performing one. However, there is no explicit when-to-use/when-not statement and no sibling is named, so the agent must infer that release_flow is the publishing counterpart.

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