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

Annotations already establish readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds real context beyond that by naming the specific discrepancy classes it surfaces and calling out the exhibit/statutory basis (Exhibit N under T.C.A. §§ 67-4-409 and 67-5-1407) for nominal-consideration transfers, which an agent could not infer from the schema. It stops short of saying how findings are returned or what happens when roll data is absent.

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 front-loaded sentence with no redundant restatement, which is good, but it is packed with three parallel detection clauses plus a parenthetical statutory citation, making it dense and slow to parse. The exhibit and code citations add authority but little actionability for an agent deciding how to call the tool.

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 read-only, closed-world audit tool with no output schema, the description does the essential job of saying what discrepancies it looks for and only requires parcel_id. It still leaves gaps an agent would want: whether the optional roll parameters change the comparison, what the response contains, and how missing or non-digitized deed records are reported.

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 100%, so all three parameters are already documented, and the baseline of 3 applies. The description adds only indirect meaning: describing the audit as a comparison against 'current county tax rolls' lightly justifies the optional current_roll_owner and current_roll_mailing inputs, but it never explains their role, precedence, or effect on results.

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 verb and resource (audit a parcel's recent deeds and transfer-tax filings against current county tax rolls) and enumerates the three findings it produces: unmapped deed backlogs, grantee mailing-address drift, and nominal-consideration transfers. It is clearly distinguishable from generic roll tools like get_property_assessment or lookup_property_tax, but it never names a sibling or an alternative workflow, so the differentiation is implicit rather than stated.

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?

Usage is only implied: the mention of comparing deeds against 'current county tax rolls' suggests it is the tool to run when ownership or mailing data may have drifted, and the optional roll owner/mailing parameters hint at a comparison workflow. There is no explicit when-to-use, when-not-to-use, or routing statement versus the many other audit_* tools.

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