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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety and open-world profile is covered. The description adds only 'public', which vaguely implies unauthenticated/visible access but does not state it as a behavior, and says nothing about lookup failure behavior or returned data.

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?

It is a single short fragment with zero waste, but it is under-specified rather than genuinely concise; there is no front-loaded verb or payload description to anchor it.

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 one-parameter read tool with no output schema, the description should at minimum state that it retrieves a case and what that entails. It does neither, leaving the agent to infer return content entirely from the name and title.

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 100% (case_id documented as 'case id'), though that documentation is itself thin. Per the high-coverage baseline, the schema carries parameter semantics and the description adds nothing; a 3 is the appropriate floor.

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 is a noun phrase ('A public moderation case') that essentially restates the resource named in the title 'Get moderation case' without stating a verb, operation, or outcome. It does hint at scope with 'public', but that is the only information not already carried by the name and title.

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 indication of when to use this tool, what preconditions apply, or what alternative to pick. No sibling tool appears to cover moderation cases, so no routing guidance is provided or implied.

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