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

With no annotations, the description carries the full burden and does substantial work: it enumerates the stored claim states (claimed, fulfilled, expired), notes that pending is derived on read, lists the no-claim states (eligible_unclaimed, ineligible with reason), and explicitly excludes dollar amounts, remaining budget, and cap values. It omits auth/permission requirements and any rate or freshness caveats, keeping it short of a 5.

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?

Front-loaded with the purpose, then the state model, then the fundingWindow scope and the negative constraints. Dense but every clause is load-bearing, particularly the explicit 'no dollar amounts' disclaimer that prevents the agent from promising budget 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?

There is no output schema or annotations, so the description is the only contract, and it covers the full state space plus the fundingWindow shape and deliberate omissions. Only the absence of auth/permission and error-condition context keeps it from being fully complete.

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?

The tool takes zero parameters, so the baseline is 4; there is nothing a parameter description could add and the description does not confuse the issue by implying hidden inputs.

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 ('Read your First-Hire Guarantee status') and no sibling targets this same guarantee object, so the agent can select it unambiguously. The first sentence alone answers what the tool does.

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?

The 'Claim-first' phrase implies an evaluation order and the description signals this is a read-only status check, but it never says when to call this versus siblings like agentlux_service_hire_status, nor any prerequisites. Usage must be inferred from the semantics of the return states.

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