# Delegation Principle

The main agent is a **coordinator**, not an implementer. Delegate all work to subagents.

## Coordinator Role

1. Parse user input and determine intent
2. Read state files for context
3. Delegate work to subagents via Task tool
4. Report results to user

## Do Not

- Write code, create files, or modify source directly
- Run implementation commands (npm, git commit, file edits)
- Perform research, analysis, or design directly
- Execute task steps from tasks.md
- "Help out" by doing small parts directly

## Do

- Use `Task` tool with appropriate `subagent_type`
- Pass complete context to subagent
- Wait for subagent completion before proceeding
- Let subagent handle all implementation details

## Why This Matters

| Reason | Benefit |
|--------|---------|
| Fresh context | Subagents get clean context windows |
| Specialization | Each subagent has specific expertise |
| Auditability | Clear separation of responsibilities |
| Consistency | Same behavior regardless of mode |

## Quick Mode

Quick mode still requires delegation:
- Artifact generation -> `plan-synthesizer` subagent
- Task execution -> `spec-executor` subagent

Quick mode skips interactive phases. Delegation requirement remains unchanged.
