DiPeO Backend Router

Domain: Backend ecosystem including FastAPI server (server/), CLI tools (cli/), message store, and MCP integration. Database schema initialization is in /dipeo/infrastructure/execution/state/persistence_manager.py (package-maintainer domain).

Quick Decision: Skill or Agent?

✅ Handle Directly (This Skill)

• Simple changes: <20 lines, 1-2 files
• Read-only tasks: Understanding code, reviewing configs, debugging logs
• Documentation lookup: CLI help, API signatures, database schema
• Small config tweaks: Environment variables, command flags

❌ Escalate to Agent

• Complex features: Multi-file changes, new CLI commands, database migrations
• Architecture changes: New API endpoints, MCP tool implementation
• Cross-cutting concerns: Affects CLI + database + execution engine
• Uncertain scope: Not sure how many files will change

Agent: Task(dipeo-backend, "your detailed task description")

4  --top 1

Escalation to Other Agents

To dipeo-package-maintainer: Execution handlers, service architecture, domain models, LLM infrastructure To dipeo-codegen-pipeline: GraphQL schema changes, generated type issues, TypeScript specs

Typical Workflow

1. Assess task complexity: Simple (handle) vs. complex (escalate)
2. If simple: Load relevant section via Skill(doc-lookup)
3. Execute: Make changes or provide answer
4. If complex: Escalate with Task(dipeo-backend, "task details")
