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

With no annotations, the description must carry the full behavioral burden. It does add real context: it discloses that it works only 'where the supported evidence model permits', that unsupported items are held rather than asserted, and that it does not certify outcomes. However, it never explicitly states read-only status (only implied by 'Inspect'), nor permissions, side effects, or result shape.

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 purpose is front-loaded in the first clause, which is good. But the four-sentence body is dense with unparseable terms such as 'yard-item' and 'source-conflict holds', and the caveats consume more space than the actionable description, reducing scannability.

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 complex, five-parameter tool with no annotations and no output schema, the description must explain both behavior and result. It sketches the deliverable ('draft building-assessment-equity comparison', separated rate scenarios versus unavailable savings) and the limits, but leaves the actual return structure and what counts as a 'hold' unexplained.

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%, so the schema already documents all five parameters, and baseline 3 applies. The description alludes to concepts tied to notice_appraised_value and actual_sqft (rate scenarios, unknown-year/rate holds) but does not map them to parameters or add format/semantic detail beyond the schema.

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 opening clause 'Inspect retained county assessments' names a specific verb and resource, but the remainder ('draft building-assessment-equity comparison', 'conditional rate scenarios', 'unknown-year/rate holds') is domain jargon that does not clarify what the tool operationally returns. It never distinguishes itself from close siblings like lookup_property_tax, get_property_assessment, or audit_square_footage_correction, so an agent cannot confidently choose it on purpose alone.

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 statement of when to use this tool versus the many sibling audit/lookup tools, and no prerequisites are given. The closing sentence lists what the tool does NOT do (certify market value, benefits, filing, payment readiness), which is a scope exclusion rather than positive usage guidance.

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