Seedance Video Generation Extension

· v1.0.0

High Risk

Orchestrate script-to-final-video production with a strict stage-gated workflow (outline → episode_plan → storyboard → storyboard_images → render), using Seedream image generation, Seedance multi-shot rendering, checkpoint-based confirmation/resume, and optional FFmpeg concatenation. Use when converting txt/json/staged artifacts into storyboard videos and a final merged mp4.

🔒 Containment

Level: maximum

Required:

SANDBOX_CONTAINER: Code execution capability

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Prompt injection patterns detected in: scripts/prepare_storyboard.py high

Mitigation: Review SKILL.md for hidden instructions. Do not use with untrusted input.

Resource abuse detected: RESOURCE_ABUSE_INFINITE_LOOP high

Mitigation: Add proper exit conditions or limits to loops

Command injection risk: MCP_SQL_BLIND high

Mitigation: Remove SQL exploitation patterns.

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Data exfiltration patterns: DATA_EXFIL_NETWORK_REQUESTS, DATA_EXFIL_ENV_VARS medium

Mitigation: Ensure network access is necessary and documented
