Responsibilities
Architect and build multi-agent systems in TypeScript where a primary agent interprets user requests and delegates to specialized sub-agents for tasks like scene composition, visual generation, timeline manipulation, and effect application
Design the interface layer between agents and the video editor, enabling agents to read project state, issue commands, and observe results in real time
Build sub-agent systems for distinct capabilities such as generating new visual content, applying transformations, adjusting timing, and compositing layers
Develop orchestration patterns that allow agents to plan multi-step edits, execute them across the timeline, and recover gracefully when results don't match intent
Create memory and context systems that help agents understand the current project state, user preferences, and editing history to make informed decisions
Implement feedback loops where agents can preview their changes, evaluate outcomes, and refine their approach before committing edits
