Create animation

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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=false, and openWorldHint=true. The description adds meaningful context beyond that: provider scopes, locks and credits are consumed, confirmation is mandatory, and only one submission is allowed (reinforcing non-idempotency). These are concrete behavioral traits, though it does not describe what happens to prior state or what is returned.

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?

Four short clauses, front-loaded with the endpoint and operation context, with no filler sentences. It is terse to the point of being cryptic, but nothing is wasted.

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 destructive, non-idempotent, credit-consuming create tool the description covers confirmation and single-submission, which is the most important behavioral risk. However, it stops short of explaining what is created or how the result is obtained, and it does not distinguish the tool from its similarly named siblings, leaving an agent to reconcile those gaps itself.

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 baseline is 3; each of the four parameters (account, confirm, payload, payload_file) is documented in the schema itself. The description adds no additional semantics for any parameter, so it neither helps nor hurts beyond the schema.

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 opens with 'POST /v5/animations', which essentially restates the title 'Create animation' and the operation name rather than explaining in prose what the tool does. It gives no differentiation from close siblings like animate_template, create_animation_template, or get_animation, so an agent cannot tell which create-path to use from the text alone.

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 states a hard operational precondition ('Mandatory confirmation before provider execution; one submission only') which is useful, but gives no when-to-use guidance relative to alternatives. Nothing tells the agent when this is preferred over animate_template or create_animation_template, so usage must be inferred.

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