ecomode

Ecomode deprecated

Hard-deprecated. Do not invoke or route this skill. Use $ultrawork directly for maintained high-throughput execution workflows.

What Ecomode Does

Overrides default model selection to prefer cheaper tiers:

Default Tier	Ecomode Override
THOROUGH	STANDARD, THOROUGH only if essential
STANDARD	LOW first, STANDARD if needed
LOW	LOW - 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 for most tasks
UPGRADE	Escalate to STANDARD when LOW tier fails or task requires multi-file reasoning
AVOID	THOROUGH tier - only for planning/critique if essential

Agent Selection in Ecomode

FIRST ACTION: Before delegating any work, read the agent reference file:

Read file: references/agent-tiers.md

This provides the complete agent tier matrix, MCP tool assignments, and selection guidance.

Ecomode preference order:

// PREFERRED - Use for most tasks
use /prompts:executor for this scoped task
use /prompts:explore for this scoped task
use /prompts:architect for this scoped task

// FALLBACK - Only if LOW fails
use /prompts:executor for this scoped task
use /prompts:architect for this scoped task

// AVOID - Only for planning/critique if essential
use /prompts:planner for this scoped task

Delegation Enforcement

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

Action	Delegate To	Model
Code changes	executor	LOW / STANDARD
Analysis	architect	LOW
Search	explore	LOW
Documentation	writer	LOW

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 (LOW tier) for file discovery, not architect
3. Prefer LOW-tier executor routing for simple changes - only upgrade if it fails
4. Use writer (LOW tier) for all documentation tasks
5. Avoid THOROUGH-tier 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 the CLI-first state surface (omx state ... --json) for ecomode lifecycle state. If explicit MCP compatibility tools are already available, equivalent omx_state calls are optional compatibility, not the default.

• On activation: omx state write --input '{"mode":"ecomode","active":true}' --json
• On deactivation/completion: omx state write --input '{"mode":"ecomode","active":false}' --json
• On cancellation/cleanup: run $cancel (which should call omx state clear --input '{"mode":"ecomode"}' --json)
