Cancel animation

cancel_animation
DestructiveIdempotent

Cancel an owned animation. Inspect cancellation_allowed and cancellation_reason. Seedance and V1 HappyHorse reject cancellation after submission starts (GENERATION_ALREADY_SUBMITTED). V1 MiniMax queued cancellation requires remote confirmation; keep polling the original task even if cancellation is uncertain. Other work already in production may not stop and credits already charged are not refunded.

Input Schema

NameRequiredDescriptionDefault
animation_idYesOwned task the user has asked to cancel.

Output Schema

NameRequiredDescriptionDefault
idYesPersist this task ID immediately after create; poll it instead of creating again.
errorNoTask failure details, independently of any usable outputs.
stageNoCurrent pipeline stage when available.
objectYesPublic task resource type.
statusYessucceeded, failed, and cancelled are terminal; cancelling is not terminal.
creditsYesQuoted, reserved, and charged credit states.
outputsNoAvailable assets, including partial outputs on failed/cancelled tasks. Always inspect them at a terminal state.
metadataNoCaller-provided metadata.
progressYesFraction from 0 to 1, not a completion-time estimate.
created_atYesUTC acceptance timestamp.
started_atNoUTC production start when known.
finished_atNoUTC terminal timestamp when known.
resolved_exportNoPersisted FPS sampling summary shared with the quote and manifest; null for legacy tasks.
normalized_inputNoNormalized public input; may contain private prompts or image references. Do not log wholesale.
cancellation_reasonNoStable reason when cancellation is unavailable: TASK_TERMINAL, CANCELLATION_PENDING, CANCELLATION_NOT_CONFIRMED, or GENERATION_ALREADY_SUBMITTED.
cancellation_allowedNoWhether a cancellation request can currently be accepted. Remote cancellation still needs confirmation.

  3. First observed

TDQS

A4.1/5.0
Behavior5/5

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

Beyond destructive/idempotent annotations it discloses the material consequences an agent cannot guess: credits already charged are not refunded, in-production work may not stop, and specific providers reject cancellation with GENERATION_ALREADY_SUBMITTED. The V1 MiniMax remote-confirmation caveat is exactly the kind of non-obvious behavior that prevents misuse.

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?

The action is front-loaded in sentence one, followed by only decision-relevant caveats about rejection, confirmation, and refunds. It is dense with provider names but no sentence is filler; slight compression would improve scanning.

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

Completeness5/5

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

With an output schema present, return fields need not be explained, and the description covers the remaining unknowns: preconditions, provider-specific failure modes, and the financial irreversibility of the call. Nothing needed to invoke it correctly is missing.

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% and the single animation_id is already documented as the owned task the user asked to cancel. The description adds no further syntax or semantics for the parameter, so the baseline 3 applies.

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?

The first sentence states a specific verb and resource ("Cancel an owned animation"), which lets an agent separate it from cancel_video_generation and cancel_animation_export by resource scope. It never names those siblings explicitly, so differentiation relies on inference from the noun.

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

Usage Guidelines4/5

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

It gives concrete preconditions ("Inspect cancellation_allowed and cancellation_reason") and a fallback rule for uncertain cases ("keep polling the original task even if cancellation is uncertain"). What's missing is explicit routing guidance versus the sibling cancel_* tools.

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