Submit the reviewed render batch

submit_render_batch
Destructive

Submits one to ten confirmed, ordered v2 renders for an exact project profile after verifying the review hash and prevalidating payloads; stops at first failure.

Instructions

Confirmed one-to-ten exact ordered v2 submissions. Verify review hash/profile and prevalidate every payload before first request. Stop at first failure, return known prior submissions and unknown attempted outcome; no retry, polling, rollback or implicit final render.

Tool call template

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

TDQS

A4/5.0
Behavior5/5

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

Goes well beyond the annotations: it discloses first-failure abort semantics, partial return behavior (known prior submissions plus unknown attempted outcome), and explicitly denies retry, polling, rollback, and implicit final render. For a destructive, non-idempotent mutation this is exactly the failure-mode context an agent needs and the annotations cannot supply.

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

Conciseness4/5

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

Very compact and front-loaded, with the submission scope stated first and constraints following. The telegraphic phrasing ('Confirmed one-to-ten exact ordered v2 submissions') is dense to the point of being hard to parse on first read, but no sentence is wasted.

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

Completeness4/5

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

For a destructive batch mutation with no output schema, the description covers failure behavior and partial-result semantics, which is the critical gap the structured fields leave. It stops short of describing the shape of a successful response beyond 'no implicit final render', but the failure-path coverage is strong.

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

Parameters4/5

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

Schema description coverage is 100%, so the baseline is 3, but the description adds real cross-parameter meaning: review_sha256 must match the preview hash for the same profile, and all payloads are validated before the first provider request. That ties the hash and profile parameters to a verification workflow rather than merely restating types.

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?

States a specific verb and resource with scope: submitting confirmed one-to-ten ordered v2 render requests, cross-referenced to a review hash. It implies the batch-submission role versus sibling preview_render_batch and validate_render, but never names them explicitly, so the differentiation is inferential rather than stated.

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?

The description establishes context (post-review, prevalidated payloads, review_sha256 must match a preview) without an explicit 'use this when / use X instead' rule. The relation to preview_render_batch is implied via the hash requirement, and validate_render is only referenced indirectly in the schema. Adequate but leaves selection to inference.

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