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

readOnlyHint=true already establishes the safe-read profile, so the description's marginal value is the access scope ('cases.read_own') and the explicit injection warning that reviewer-authored fields must be treated as data. That warning is genuinely useful context beyond the annotations, but pagination, latency, and failure behavior for a non-existent or unauthorized case_id are unaddressed.

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 entire definition is one long run-on sentence that buries the operation under a dense parenthetical inventory of return fields before reaching the important safety instruction. The content is largely justified, but restructuring into a lead sentence plus short bullets would make it far easier to parse.

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 the heavy lifting by enumerating returned fields, and it adds the injection caveat and access capability, which is substantial. What remains missing is how to obtain a case_id and any error or authorization-failure behavior, which matters for a lookup keyed on a caller-supplied identifier.

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 0% and the single required integer parameter case_id is documented nowhere in the schema, so the description must carry that burden. It implies scoping to 'your cases' but never explains where a case_id comes from or what happens on an invalid or foreign id, leaving the parameter's provenance and constraints to guesswork.

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 specific resource ('one of your cases in full') and enumerates its contents (state, wait, current draft, public reply, draft versions, audit trail, next step), which makes the retrieval purpose unmistakable. It never names a sibling, so the boundary with tools like get_audit_result or list_review_triage must be inferred.

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 and no comparison with alternatives such as get_audit_result, even though several sibling tools return overlapping case-related data. The only directive present ('show it to them when it is not null') governs handling of a returned field, not selection or invocation of this tool.

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