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

With no annotations, the description carries the burden and discloses the key behavioral traits: this is a paid purchase, the charge happens via pay-per-event, and the returned download link is valid for 24 hours. It could further clarify irreversibility or authentication needs, but the financial side effect and link expiry are clearly stated.

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?

The description is compact and front-loaded: it states what is bought, what the CSV contains, how payment works, and what is returned. Every clause adds useful information.

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?

Given the lack of parameters, annotations, and output schema, the description provides enough context to call the tool: dataset contents, payment model, and return value. Minor gaps such as link regeneration or auth requirements remain, but the essential behavior is covered.

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 has zero parameters, so there is nothing for the description to disambiguate. The baseline for a parameterless tool 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 uses a specific verb and resource: buy the full active Loker Dollar job dataset. It lists the exact CSV fields included, so an agent can distinguish this dataset-purchase tool from sibling job-search and application tools.

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?

It clearly states the purchase channel and payment mechanism: only through the Apify listing, with the run's pay-per-event charge serving as payment. It does not explicitly compare this tool to alternatives like search_jobs, but the intended use case is unambiguous.

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