# 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")`

## Documentation Sections (Load On-Demand)

Use `Skill(doc-lookup)` with these anchors when you need detailed context:

**Architecture & Ownership**:
- `docs/agents/package-maintainer.md#your-domain-of-expertise` - Code layers and ownership
- `docs/agents/package-maintainer.md#core-architectural-principles` - Service architecture, LLM integration

**Implementation**:
- `docs/agents/package-maintainer.md#your-responsibilities` - Node handlers, services, GraphQL resolvers

**Patterns & Imports**:
- `docs/agents/package-maintainer.md#common-patterns` - Envelope, service registry, node handlers
- `docs/agents/package-maintainer.md#key-import-paths` - Common imports

**Escalation**:
- `docs/agents/package-maintainer.md#when-you-need-help-escalation-paths` - When to escalate

**Example doc-lookup call**:
```bash
python .claude/skills/doc-lookup/scripts/section_search.py \
  --query "envelope-pattern" \
  --paths docs/agents/package-maintainer.md \
  --top 1
```

## 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
