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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds only the content scope (the four rule categories), with nothing about behavior on an invalid state code or any lookup constraints. With annotations carrying the burden, this is adequate but thin.

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 noun-phrase sentence with zero filler, front-loading the scope ('One state's') and then the payload. Every clause names a distinct category of returned data.

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 the work of enumerating return fields, which it handles well. Slight gaps remain: 'annual report' is ambiguous (requirements vs. due date vs. fee), and there is no hint about response shape or whether the four categories are always present for every state.

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% — the code parameter is documented as a two-letter state code with an example (`WY`). The description adds nothing beyond that: it does not say what happens for unknown codes or direct the agent to list_states for valid values. 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?

Names a specific resource (one state's registration requirements) and enumerates the exact content returned: filing fees, annual report, accepted name endings, publication rules. The singularity implicitly separates it from the sibling list_states, though no verb ('retrieve') is stated and the distinction is never made explicit.

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: an agent infers this is the lookup to run when it needs one state's filing requirements, presumably during formation or application planning. There is no statement of when to prefer it over list_states, no prerequisites, and no note that the code should come from list_states.

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