DiPeO Codegen Pipeline Router

DiPeO Codegen Pipeline Router

Domain: Complete TypeScript → IR → Python/​GraphQL pipeline (/​dipeo/​models/​src/, /​dipeo/​infrastructure/​codegen/, generated code diagnosis).

Quick Decision: Skill or Agent?

✅ Handle Directly (This Skill)

• Simple lookups: Understanding codegen workflow, reviewing TypeScript specs
• Read-only tasks: Checking generated code structure, reviewing IR output
• Pattern reference: snake_case naming rules, type mapping examples
• Small spec tweaks: Minor TypeScript field changes (<5 lines, 1 file)
• Workflow questions: "How do I run codegen?", "What's the IR structure?"

❌ Escalate to Agent

• New node types: Creating complete TypeScript specs with IR builders
• IR builder changes: Modifying AST processing, type conversion logic
• Generated code diagnosis: Tracing why generated code is wrong
• Template modifications: Changing Jinja templates for code generation
• Complex spec changes: Multi-field changes affecting multiple generated files
• Type system updates: Changes to UnifiedTypeConverter or type mappings

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

Example doc-lookup call:

  --query "naming-standards" \
  --paths docs/​agents/​codegen-pipeline.md \
  --top 1

Escalation to Other Agents

To dipeo-package-maintainer: Runtime handler issues, service architecture (if generated code is correct) To dipeo-backend: GraphQL schema deployment, server config (if generation is correct)

Typical Workflow

1. Assess complexity: Simple lookup/​guidance vs. complex generation task
2. If simple: Load relevant section via Skill(doc-lookup), provide guidance
3. If diagnosis needed: Trace TypeScript → IR → Python (use diagnosis docs)
4. If complex: Escalate with Task(dipeo-codegen-pipeline, "task details")
