Seedance 2.5 timestamp plan linter

Use this skill when a Seedance 2.5 edit needs exact timing rather than a broad rewrite. Provide a redacted request plan with a 4-30 second target duration, a prompt, and timestamped edit segments.

Each segment must have a unique ID, a start and end inside the target duration, an operation (replace, remove, or adjust), a non-empty instruction, and explicit preserve/change fields. Overlapping segments are blocked so the buyer can review which instruction owns each interval. The output is local and does not call or upload to an API.

Inputs

• - Model ID, target duration, prompt, and optional reference labels.
• Timestamped segments with operation, instruction, fields, and human review status.

Outputs

• - seedance25_timestamp_contract.json with normalized segments and a stable hash.
• INLINECODE4 with the manual approval boundary.

The contract does not prove that an edit will preserve continuity. Review rights, provider access, cost, and the actual output manually.
