 ## OVERVIEW
 
-7 AI agents for multi-model orchestration. Sisyphus orchestrates, specialists handle domains.
+AI agent definitions for multi-model orchestration. 7 specialized agents: Sisyphus (orchestrator), oracle (strategy), librarian (research), explore (grep), frontend-ui-ux-engineer, document-writer, multimodal-looker.

-## HOW TO ADD
+## HOW TO ADD AN AGENT
 
 1. Create `src/agents/my-agent.ts`:
    ```typescript
+   import type { AgentConfig } from "@opencode-ai/sdk"
+   
    export const myAgent: AgentConfig = {
      model: "provider/model-name",
      temperature: 0.1,
-     system: "...",
-     tools: { include: ["tool1"] },
+     system: "Agent system prompt...",
+     tools: { include: ["tool1", "tool2"] },  // or exclude: [...]
    }
    ```
-2. Add to `builtinAgents` in index.ts
-3. Update types.ts if new config options
+2. Add to `builtinAgents` in `src/agents/index.ts`
+3. Update `types.ts` if adding new config options
 
-## MODEL FALLBACK
+## AGENT CONFIG OPTIONS
 
-`createBuiltinAgents()` handles fallback:
-1. User config override
-2. Installer settings (claude max20, gemini antigravity)
-3. Default model
+| Option | Type | Description |
+|--------|------|-------------|
+| model | string | Model identifier (provider/model-name) |
+| temperature | number | 0.0-1.0, most use 0.1 for consistency |
+| system | string | System prompt (can be multiline template literal) |
+| tools | object | `{ include: [...] }` or `{ exclude: [...] }` |
+| top_p | number | Optional nucleus sampling |
+| maxTokens | number | Optional max output tokens |
 
-## ANTI-PATTERNS
+## MODEL FALLBACK LOGIC
 
-- High temperature (>0.3) for code agents
-- Broad tool access (prefer explicit `include`)
-- Monolithic prompts (delegate to specialists)
-- Missing fallbacks for rate-limited models
+`createBuiltinAgents()` in utils.ts handles model fallback:
+
+1. Check user config override (`agents.{name}.model`)
+2. Check installer settings (claude max20, gemini antigravity)
+3. Use default model
+
+**Fallback order for explore**:
+- If gemini antigravity enabled → `google/gemini-3-flash`
+- If claude max20 enabled → `anthropic/claude-haiku-4-5`
+- Default → `opencode/grok-code` (free)
+
+## ANTI-PATTERNS (AGENTS)
+
+- **High temperature**: Don't use >0.3 for code-related agents
+- **Broad tool access**: Prefer explicit `include` over unrestricted access
+- **Monolithic prompts**: Keep prompts focused; delegate to specialized agents
+- **Missing fallbacks**: Consider free/cheap fallbacks for rate-limited models
+
+## SHARED PROMPTS
+
+- **build-prompt.ts**: Base prompt for build agents (OpenCode default + Sisyphus variants)
+- **plan-prompt.ts**: Base prompt for plan agents (legacy)
+- **prometheus-prompt.ts**: System prompt for Prometheus (Planner) agent
+- **metis.ts**: Metis (Plan Consultant) agent for pre-planning analysis
+
+Used by `src/index.ts` when creating Builder-Sisyphus and Prometheus (Planner) variants.
