Animate template

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, but the description adds real context beyond them: provider scopes and locks apply, credits are consumed, a confirmation gate is mandatory, and the call is one-shot (consistent with idempotentHint=false). It still omits what is actually produced or how partial failures are handled.

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?

Three short telegraphic clauses with no filler, front-loaded with the endpoint, then constraints. It is efficient, though sentence-fragment style makes it slightly harder to parse than prose.

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?

This is an open-world, credit-consuming, destructive-hinted operation with a nested payload object and no output schema. The description never says what comes back or how to retrieve the result (e.g., via list_tool_jobs/poll_job), leaving an agent that just fired a one-shot render with no stated way to obtain or verify output.

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 80%, so `uid`, `confirm`, `account`, `payload` and `payload_file` are already documented in the schema, including the payload/payload_file exclusivity. The description adds nothing about parameter meaning, so the baseline 3 applies.

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 gives an HTTP method and path ('POST /v5/animation_templates/{uid}/animate'), which implies animating an existing animation template, but never states the purpose in plain language (e.g., 'renders an animated GIF/video from an animation template'). The `uid` binding distinguishes it from list/create/delete siblings, but the verb-resource pair is only inferable from the URL, not stated.

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 tells the agent that a confirmation step is mandatory before provider execution and that only one submission is allowed — useful invocation constraints — but gives no guidance on when to choose this over create_animation or the other animation siblings, and no prerequisites beyond 'V5 operation'.

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