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

Annotations already declare readOnlyHint=true, so safety is covered; the description usefully adds that the validation scope covers entities, tracks, clips, timing and references. It does not disclose whether issues are merely reported or auto-fixed, how failures are surfaced, or any rate/permission 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?

A single front-loaded sentence with no filler or repetition. It is efficient, though the terseness leaves required content unstated elsewhere.

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 and only a readOnlyHint annotation, the description should explain what a validation run returns (issue list? severity? does it persist a job?), how to obtain agentToken, and how it relates to studio_get_job or studio_apply_actions. None of that is present.

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% and there are two required parameters. The description says nothing about projectId or agentToken (format, where the token comes from, required scope), so it fails to compensate for the schema gap beyond the self-evident parameter names.

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 ("Checks") and resource (project) and enumerates the five integrity dimensions checked, so the agent knows this is an inspection/validation operation rather than a mutation. It does not explicitly contrast itself with siblings like studio_get_project_summary or studio_request_preview, so it stops short of a 5.

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?

There is no when-to-use guidance, no mention of prerequisites or ordering relative to studio_apply_actions or studio_request_export, and no statement of when validation should be skipped. The agent must infer usage from the name alone.

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