Logging & Performance Benchmarks +**Decision**: Full observability with Redis-backed benchmark storage + +**Rationale**: +- Track Steward recommendations vs. Tatlock's actual tool usage +- Measure performance metrics (latency, token usage) +- Cross-session analysis for optimization +- Identify recommendation accuracy over time + +### 2. Steward Fallback Behavior +**Decision**: Explicit missing capability communication + +**Rationale**: +- No suitable tools → Steward states "missing capabilities" with description +- Can suggest what type of tool would be helpful +- Code errors → standard exception handlers (don't suppress real errors) +- Better UX than silent failures or defaulting to all tools + +### 3. Conversation History for Steward +**Decision**: Steward sees FULL conversation, not just current turn + +**Rationale**: +- Can identify references to previous topics +- Provides contextual notes to Butler +- "Two sets of eyes" on conversation +- Example: "User mentioned Python debugging in turn 3, relevant details: async code" + +### 4. Registry Pattern +**Decision**: Separate Household Registry from Model Registry + +**Rationale**: +- Tools belong to household members, not models +- Clean separation of concerns +- Executive summaries for coordination, details for execution + +### 5. Tool Composition +**Decision**: PydanticAI FunctionToolset + CombinedToolset + +**Rationale**: +- Native PydanticAI pattern +- Clean composition and filtering +- Dynamic scoping per request + +### 6. Tool Scoping +**Decision**: Compile-time scoping via toolset creation + +**Rationale**: +- Tools not even visible to LLM +- Cleaner than runtime permission checks +- Enforced at PydanticAI level + +### 7. Organization +**Decision**: Domain-based household directories + +**Rationale**: +- Each household member owns their tools +- Clear bounded contexts +- Example: `src/agents/tatlock_core/`, `src/agents/librarian/` (future) + +--- + +## Infrastructure Requirements + +### Redis Setup + +Development (quick start): +```bash +# Docker (recommended) +docker run -d -p 6379:6379 --name tatlock-redis redis:7-alpine + +# Or local installation +# macOS: brew install redis && brew services start redis +# Linux: sudo apt install redis-server && sudo systemctl start redis +``` + +Production (docker-compose.yml): +```yaml +services: + redis: + image: redis:7-alpine + ports: + -
