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

Annotations already indicate non-read-only, non-destructive, and idempotent behavior. The description adds no behavioral detail beyond saying 'Update', which is redundant. It does not describe side effects, response behavior, or what changes occur.

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 description is very short, but brevity here is under-specification, not efficiency. It lacks structure and does not front-load key information; it is a single vague sentence.

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 tool with 8 parameters, 4 required, a nested details object, and no output schema, the description provides almost no operational context. An agent would have no idea what the tool does, what it returns, or how to invoke it correctly.

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 explain the parameters, but it does not. None of the eight parameters (projectId, requestId, idempotencyKey, expectedVersion, details, etc.) are mentioned or clarified. The vague 'privacy-filtered project metadata' does not map to any specific field.

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 verb ('Update') and a resource ('hosted fail presentation request'), but the meaning of 'fail presentation request' is unclear and not differentiated from siblings like publish_presentation_request or retry_presentation_request. The phrase 'privacy-filtered project metadata' adds confusion rather than clarity.

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 guidance on when to use this tool versus alternatives. No context about triggering conditions, prerequisites, or distinctions from other presentation-related tools is provided.

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