The download includes .env.local placeholders when needed. Add real values for: OPENAI_API_KEY.
4
Customize the agent and tool files
Adapt prompts, tools, and stop conditions in the generated project for your product.

lib/stages.ts
Stage configuration array defining 4 stages (Brand Identity form, Target Audience form, Competitive Landscape chat, Strategy Synthesis). Each stage has lock items, initial inputs, agent instructions, and tool sets.
ai/levee-stream-config.ts
Builds streamText config per stage mode. Contains system prompt construction with mode-specific rules (form, chat, synthesis), tool set selection, and stop conditions. Central orchestration logic.
levee/route.ts
Streaming API endpoint. Validates with Zod, calls buildStreamConfig, uses prepareStep to force evaluateLock after tool calls, streams lock updates via onStepFinish, and generates synthesis document on completeStage.
