name: dipeo-package-maintainer description: Router skill for DiPeO runtime Python code (execution handlers, service architecture, domain models, LLM infrastructure). Use when task mentions node handlers, EventBus, ServiceRegistry, Envelope pattern, or domain logic. For simple tasks, handle directly; for complex work, escalate to dipeo-package-maintainer agent. allowed-tools: Read, Grep, Glob, Bash, Skill

DiPeO Package Maintainer Router

Domain: Runtime Python in /dipeo/ (application, domain, infrastructure - EXCLUDING codegen and generated code).

Quick Decision: Skill or Agent?

✅ Handle Directly (This Skill)

• Simple changes: <20 lines, 1-2 files
• Read-only tasks: Understanding patterns, reviewing implementation
• Pattern lookup: Envelope usage, service registration examples
• Small fixes: Typos, minor refactors, simple handler tweaks

❌ Escalate to Agent

• New node handlers: Creating handlers with complex logic
• Service architecture: EventBus integration, ServiceRegistry configuration
• Domain model changes: Conversation management, memory strategies
• Multi-file refactoring: Affects >2 files or cross-layer changes
• Generated code issues: If generated APIs don't work, escalate to dipeo-codegen-pipeline first

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

Escalation to Other Agents

To dipeo-codegen-pipeline: Generated code issues, TypeScript specs, new node types, GraphQL schema To dipeo-backend: CLI commands, server config, database schema, MCP server

Typical Workflow

1. Assess complexity: Simple pattern lookup vs. complex implementation
2. If simple: Load relevant section via Skill(doc-lookup), provide guidance or make small change
3. If complex: Escalate with Task(dipeo-package-maintainer, "task details")
4. Generated code problems: First check if it's a generation issue → escalate to dipeo-codegen-pipeline
