Run tab

run_tab

Re-audits the tab's URL. Consumes the same daily allowance as POST /api/audit — past it, 402 with accepts[].

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.7/5.0
Behavior4/5

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

Annotations already declare a non-read-only, non-idempotent, open-world call, so the bar is lower. The description still adds real value beyond them: it discloses the shared daily quota with POST /api/audit and the exact failure contract (402 with accepts[]), which an agent cannot infer from annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, zero filler. The action is front-loaded and the quota/error caveat follows immediately, with nothing restating the title or schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Quota and error behavior are covered, but with no output schema the description is silent on what a successful re-audit returns (an audit record, a job handle, a URL to results). For a consuming, state-changing operation that is a meaningful gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with both id and guest_token fully documented inline, so the schema carries the burden. The description adds no format or constraint detail for either parameter, which is acceptable at this coverage level but earns only the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Names a specific verb and resource: 'Re-audits the tab's URL.' The 're-' prefix and the tab reference distinguish it from audit_url and audit_site, though it never explicitly contrasts itself with those siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the name and by the note that it consumes the same allowance as POST /api/audit, but there is no explicit statement of when to pick this over audit_url or create_tab, nor any precondition (e.g. that the tab must already exist).

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