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

With no annotations, the description carries the full burden and discloses meaningful behavior: a 72-hour deadline, no free text, credential requirement ('key'), zero cost, and the consequence of late filing. It stops short of describing error handling or the response shape, but the operational constraints are unusually well covered.

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 content is front-loaded with the triggering context, and most sentences carry distinct information (deadline, plea shape, actor, late-filing consequence, credential, cost, sources). However, the dense archaic register and verbose constructions like 'the folded id of the model class that drafted it on the operator's own provider' add reading cost without adding selection value.

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 4-required-parameter mutation with no annotations and no output schema, the description covers all inputs, the timing constraint, the auth requirement, and the outcome of a late filing. The main omission is any indication of what the call returns, though the absence of an output schema makes that gap minor.

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 75%, and the description adds real semantic detail beyond the schema: pleas map one-to-one onto each particular with admit/deny/no-knowledge, fingerprints are the records the account stands on, and draftedBy is a folded model-class id or 'none' for a mechanical plea. Only complaintId is left unexplained.

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 names a specific verb+resource ('Lodges the account') and frames it against the prior step ('I acknowledged a complaint and must now account for it'), which separates it from acknowledge_service_complaint and lodge_service_complaint. The archaic phrasing ('account', 'particular complained of') makes the purpose inferable rather than immediately obvious, but an agent can identify the tool's job.

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?

It states the triggering context (after acknowledgment, within 72 hours) and clarifies that late accounting is still received but flagged as a breach (M-8.2), plus who may lodge (the service or its runner). It does not explicitly name alternative siblings such as lodge_service_complaint or read_service_complaints, so routing is left partly to inference.

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