Seedance 2.5 多角色对白契约

Use this skill before submitting a multi-character Seedance 2.5 generation request. It checks a redacted cast file offline and produces a deterministic contract for an authorized operator.

Prerequisites

• - Python 3.9 or newer.
• A UTF-8 JSON file with characters, dialogue, and rights_review fields. Use the included example as a starting point.
• Character and voice reference files must be supplied by the buyer in their own environment. This skill only validates identifiers and metadata.

Inputs and outputs

Run python scripts/check_cast.py examples/pass_cast.json --out contract.json --report contract.md.

The input contains one object per character with a unique character_id, a numeric display_order, visual_reference_ids, voice_reference_ids, and a min_voice_reference_seconds value. Dialogue lines name their owner and include a planned time window. The output is a JSON contract and a Markdown report. The report never embeds media or secrets.

Execution and acceptance

1. 1. Copy the example and replace redacted identifiers only.
2. Run the command above. Exit code 0 means the contract is ready for an authorized generation handoff; exit code 1 means fix the listed errors.
3. Confirm that every voice reference is rights-cleared and that the actual model interface still supports the intended input combination before any upload or paid generation.

The checker enforces unique character IDs, contiguous left-to-right order, at least one visual reference, at least one voice reference, a minimum voice-reference duration of 2 seconds, owned dialogue, valid time windows, and a completed rights review. It does not prove that a file exists, that a voice belongs to a person, or that the model will preserve identity.

Privacy, permissions, and recovery

Do not place real names, phone numbers, access tokens, private URLs, or media bytes in the example. Obtain written permission for a person\'s likeness and voice. If a reference is missing, a line is ambiguous, or rights are not confirmed, stop and correct the input; do not retry a paid request automatically.

Standalone use

This skill is useful without the companion auditor: it creates a preflight contract that can be handed to any authorized Seedance 2.5 operator or a later audit step.
