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

Beyond the annotations, the description discloses critical behavior: this is a paid action that validates sum, IDs, signatures, pricing revision, funds, and approval before debiting. It also explains non-atomic partial success, persistence of successful scenes, and recovery semantics, which are essential for a destructive financial operation.

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 front-loaded with the paid-action warning and core submission scope, followed by validation, partial-success, and recovery details. Every sentence adds operational value with no filler.

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?

For a complex destructive batch tool with no output schema and annotation-covered safety flags, the description covers the most important agent-facing behavior: payment, validation, partial success, and recovery. It is not fully complete because dispatch_limit and post-partial tracking via batch_status are not explained.

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?

With 0% schema description coverage at the top level, the description compensates for several key parameters: scene quotes, exact sum, scene IDs, pricing revision, approval, and batch_id recovery. However, it does not explain dispatch_limit and only indirectly maps to approval_handle and expected_total_coins, leaving meaningful gaps.

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-resource pair: submit 1–10 independent, user-approved scene quotes from aimixer_batch_quote. It clearly marks this as a paid batch submission and differentiates it from quote generation by naming the source tool.

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 establishes the required precondition of using quotes from aimixer_batch_quote and user approval, and it gives recovery guidance: reuse the same batch_id and scene_ids and never regenerate completed scenes. It does not explicitly compare against sibling alternatives like aimixer_submit or batch_status, so it stops short of full when/when-not guidance.

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