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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed-world scope, so safety is covered. The description adds useful context about what is inspected (penalty/interest accrual, multi-year exposure, foreclosure sale risk), but it omits a key behavioral fact for a tool with zero required parameters: whether parcel_id, property_address, or either is needed to get a result.

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; each enumerated item is substantive. It is dense with agency-specific jargon (County Trustee, Chancery Court) but no sentence is wasted.

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 roughly sketch what the audit reports, which helps. However, for a two-optional-parameter tool with no required inputs, the definition never states the input contract or what a returned result contains, leaving a meaningful gap.

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% with only two parameters and both carry examples, so the schema already carries the parameter burden. The description adds nothing about the identifiers — notably it does not say that only one of the two may be needed — so the baseline 3 applies.

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 uses a specific verb ('Audit') with a clearly bounded resource: active County Trustee delinquent property tax liens, penalty/interest, multi-year exposure, and Chancery Court foreclosure tax sale risk. That is far more specific than a generic property-tax audit, though it never names the closest sibling (e.g. audit_property_tax or audit_retroactive_tax_recovery) to draw the boundary explicitly.

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?

The use case is implied by the enumerated audit dimensions — an agent can infer this is for delinquency/foreclosure exposure checks — but there is no explicit when-to-use or when-not-to-use statement, and no guidance about choosing it over the other tax-related audit siblings.

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