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
spawn_sub_agent(subagent_type="oh-my-codex:executor-low", model="haiku", prompt="...")
spawn_sub_agent(subagent_type="oh-my-codex:explore", model="haiku", prompt="...")
spawn_sub_agent(subagent_type="oh-my-codex:architect-low", model="haiku", prompt="...")

// FALLBACK - Only if LOW fails
spawn_sub_agent(subagent_type="oh-my-codex:executor", model="sonnet", prompt="...")
spawn_sub_agent(subagent_type="oh-my-codex:architect-medium", model="sonnet", prompt="...")

// AVOID - Only for planning/critique if essential
spawn_sub_agent(subagent_type="oh-my-codex:planner", model="opus", prompt="...")

Delegation Enforcement

Ecomode maintains all delegation rules from core protocol with cost-optimized routing:

| Action | Delegate To | Model | |--------|-------------|-------| | Code changes | executor-low / executor | haiku / sonnet | | Analysis | architect-low | haiku | | Search | explore | haiku | | Documentation | writer | haiku |

Background Execution

Long-running commands (install, build, test) run in background. Maximum 20 concurrent.

Token Savings Tips

1. Batch similar tasks to one agent instead of spawning many
2. Use explore (haiku) for file discovery, not architect
3. Prefer executor-low for simple changes - only upgrade if it fails
4. Use writer (haiku) for all documentation tasks
5. Avoid opus agents unless the task genuinely requires deep reasoning

Disabling Ecomode

Ecomode can be completely disabled via config. When disabled, all ecomode keywords are ignored.

Set in ~/.codex/.omx-config.json:

{
  "ecomode": {
    "enabled": false
  }
}

State Management

Use omx_state MCP tools for ecomode lifecycle state.

• On activation: state_write({mode: "ecomode", active: true})
• On deactivation/completion: state_write({mode: "ecomode", active: false})
• On cancellation/cleanup: run $cancel (which should call state_clear(mode="ecomode"))
