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

With no annotations, the description carries the full behavioral burden. It usefully enumerates what the payload contains (rules, ceilings, caps, review dates), which goes beyond the schema, but it omits important behavior: both parameters are optional, so it never says what happens with no arguments, nor whether results are county-level defaults, cached, or authoritative.

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 the verb first and the returned artifacts listed efficiently. 'Comprehensive' is the one piece of filler, but nothing else wastes space.

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?

No output schema and no annotations, so the description is the only source of behavioral detail. It covers return content reasonably well but leaves the zero-required-parameter case and data precedence (state vs county granularity) unspecified — a real gap for a lookup whose inputs are both optional.

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% and both parameters carry examples, so the schema already does this work. 'For any county/state' only restates scope; it adds no guidance on whether county can be supplied without state or how state-only requests resolve.

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?

States a specific verb (Retrieve) and a concrete resource: statutory exemption rules, Senior Freeze ceilings, Disabled Veteran caps, and review dates scoped to a county/state. An agent can tell this is a jurisdiction-level reference lookup rather than a parcel-level audit like audit_senior_tax_freeze, though the description never names that distinction 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?

No statement of when to use this versus the many audit_* relief tools that overlap in subject matter (senior freeze, disabled veteran relief, surviving spouse). 'For any county/state' implies jurisdiction-level scope but no exclusion or prerequisite is given.

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