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

The description adds meaningful behavior beyond annotations: it returns a job id immediately, the quote is emailed within ~15 minutes, pricing tiers are disclosed, and work only starts after payment via pay_audit. This clearly communicates the asynchronous nature and the payment gate, which annotations alone do not convey. No contradiction with annotations.

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 two sentences with no filler. It front-loads the core action and immediate result, then adds the critical payment prerequisite. Every sentence 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?

The description covers the essential workflow: create job, receive job id, get emailed quote, pay before work begins. Given the simple parameter set and annotations, this is sufficient for an agent to call the tool correctly. Minor gaps like how to retrieve the result later are not required for invocation and are covered by sibling tools.

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%, so the schema already documents all three parameters. The description adds context about email delivery and payment but does not materially explain the brief or source parameters beyond what the schema states. Baseline 3 is appropriate because the schema carries the parameter documentation burden.

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 clearly states a specific action ('Create a private research job (Oxaide)') and resource, and differentiates it from sibling tools by describing the immediate job-id response and downstream quote/payment flow. The title 'Request Oxaide research' reinforces this. An agent can easily tell this creation tool apart from get_audit, list_audits, and pay_audit.

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 description implies usage context by defining what the tool creates and mentions that payment should follow via pay_audit. It does not explicitly state when to use this tool versus the sibling get_audit/get_audit_result/list_audits tools, nor does it state exclusions. The workflow hint is useful but leaves the when-to-use guidance to inference.

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