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

The supplied annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety and side-effect behavior are covered. The description adds the domain boundary ('US') and a summary of the returned payload (requirements, pay terms, sourced listing link), but says nothing about result ordering, pagination beyond the limit parameter, or total-count behavior.

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, no filler. The eligibility scope is front-loaded before the filter list, and the return content is dispatched in a single trailing clause. Every phrase earns its place.

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 usefully states what a result contains (requirements, pay terms, link to sourced listing), and it frames the eight optional filters. It stops short of explaining default behavior when no filters are passed or how results are ranked, which would matter for a broad free-text-plus-facets search.

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%, including enum value explanations for vehicle, category and background_check, so the schema already carries the parameter meaning. The description only lists filter dimensions and closes with 'and more', adding no syntax, format or interaction detail beyond what the schema states, so the baseline of 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?

The description gives a specific verb and resource: 'Find US jobs and gig apps a person can start without a job interview', with an explicit filter surface and return content. It is clearly a search tool, distinguishable in intent from detail-oriented siblings like get_platform, but it never names those siblings, so the differentiation is left implicit.

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 use case (searching for no-interview work filtered by constraints) is clear from the description, but there is no explicit guidance on when to prefer this over list_categories, get_platform, or dataset_summary, and no stated exclusions. All eight parameters are optional, yet the description does not say what happens with no filters applied.

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