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

No annotations exist, so the description carries the full burden, and it discharges most of it: it discloses the snapshot (non-live) nature, that live_active_verified is always false, that the agent must confirm at verify_url in every answer, that results are not an FCRA consumer report, and how unloaded states respond. It does not state rate limits, data freshness/as-of date, or coverage completeness per state, so it falls one notch short of the top.

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?

Dense and front-loaded, putting the snapshot qualifier and state list first and the critical live_active_verified/FCRA caveats after the filter mechanics. The state enumeration appears twice ('States accepted' vs 'loaded now'), which is meaningful but reads as slight redundancy, and the telegraphic fragments cost a little readability.

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 7-parameter read tool with no output schema, the description covers the essentials an agent needs to call it correctly: filters, limits, per-state availability, and the required downstream step of confirming at verify_url. It does not sketch what a result record contains beyond verify_url/live_active_verified, nor the as-of date of the snapshot, which leaves non-critical gaps.

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 0%, so the description must compensate and largely does: business_name requires 3+ characters, county is valid for CA/TX/FL but not WA, city narrows, limit range is 1-10 over the schema default of 5, and state's accepted vs currently loaded values are spelled out. license_number and zip formats/match behavior are left undefined.

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 and resource ('Search a SNAPSHOT of public contractor-licence data') and enumerates the four state sources with their registries (CSLB, TDLR, DBPR, L&I), which lets an agent distinguish it from the CA-only sibling search_cslb_bulk_snapshot without opening a schema. It stops short of explicitly naming that sibling or any other alternative.

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?

Gives concrete usage context: supply license_number, business_name (3+ chars), zip and/or county with the CA/TX/FL-only caveat, city narrows, limit 1-10, and a clear when-not via 'A state not loaded yet answers state_unavailable'. No routing guidance relative to the sibling tools such as search_cslb_bulk_snapshot or extract_web_context.

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