# Ecomode Skill

Token-efficient model routing. This is a **MODIFIER**, not a standalone execution mode.

## What Ecomode Does

Overrides default model selection to prefer cheaper tiers:

| Default Tier | Ecomode Override |
|--------------|------------------|
| HIGH (opus) | MEDIUM (sonnet), HIGH only if essential |
| MEDIUM (sonnet) | LOW (haiku) first, MEDIUM if fails |
| LOW (haiku) | LOW (haiku) - no change |

## What Ecomode Does NOT Do

- **Persistence**: Use `ralph` for "don't stop until done"
- **Parallel Execution**: Use `ultrawork` for parallel agents
- **Delegation Enforcement**: Always active via core orchestration

## Combining Ecomode with Other Modes

Ecomode is a modifier that combines with execution modes:

| Combination | Effect |
|-------------|--------|
| `eco ralph` | Ralph loop with cheaper agents |
| `eco ultrawork` | Parallel execution with cheaper agents |
| `eco autopilot` | Full autonomous with cost optimization |

## Ecomode Routing Rules

**ALWAYS prefer lower tiers. Only escalate when task genuinely requires it.**

| Decision | Rule |
|----------|------|
| DEFAULT | Start with LOW tier (Haiku) for most tasks |
| UPGRADE | Escalate to MEDIUM (Sonnet) when LOW tier fails or task requires multi-file reasoning |
| AVOID | HIGH tier (Opus) - only for planning/critique if essential |

## Agent Selection in Ecomode

**FIRST ACTION:** Before delegating any work, read the agent reference file:
```
Read file: docs/shared/agent-tiers.md
```
This provides the complete agent tier matrix, MCP tool assignments, and selection guidance.

**Ecomode preference order:**

```
// PREFERRED - Use for most tasks
Task(subagent_type="oh-my-claudecode:executor-low", model="haiku", prompt="...")
Task(subagent_type="oh-my-claudecode:explore", model="haiku", prompt="...")
Task(subagent_type="oh-my-claudecode:architect-low", model="haiku", prompt="...")

// FALLBACK - Only if LOW fails
Task(subagent_type="oh-my-claudecode:executor", model="sonnet", prompt="...")
