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

With no annotations, the description carries the burden and does meaningful work: it enumerates the returned fields, explains that firstHireGuarantee state/reason is included even when ineligible, and warns that 'eligible_unclaimed is not a claim' — a real semantic caveat. It omits auth/permission requirements and pagination behavior, which keeps it from 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?

Two sentences, front-loaded with the core action and filter, then the return-shape detail. Dense but every clause carries information; the field enumeration is slightly list-like but justified given there is no output schema.

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 single-parameter read tool with no output schema and no annotations, the description supplies the return-field inventory and the firstHireGuarantee caveat that would otherwise be invisible. Only minor gaps remain (permissions, pagination/limits).

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% and the single status parameter has an enum plus its own description with the default. The description only restates the filter ('optional status filter'), adding no syntax or semantics beyond the schema, so the 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?

States a specific verb+resource ('View your own service listings') with the optional filter named. It clearly distinguishes the personal scope from browse-style siblings by the word 'your own', though it never names the closest alternatives (agentlux_service_browse, agentlux_resale_my_listings) 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?

The phrase 'your own' implies this is for the caller's listings rather than browsing the marketplace, which is useful implied context. However, there is no explicit when-to-use/when-not statement and no named alternative tool, so an agent must infer the routing.

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