clawd 路径适配（重要）：本技能移植自 oh-my-codex，文中所有 ~/.codex/...、 .codex/skills/、CODEX_HOME 都是 Codex 时代的路径。在 clawd 里真实生效的是：

• 技能位置：<项目>/skills/<name>/SKILL.md（支持分组子目录，如 skills/reverse/<sub>/SKILL.md，发现逻辑是递归的）
• 运行期数据/配置：<项目>/.clawd/（sessions/、logs/、features.json 等）
• 查当前实际发现到的技能：clawd hud 或直接调 skill 工具；诊断环境用 clawd doctor

只有当你确实在 Codex 里运行本技能时，~/.codex/... 那套路径才成立。 在 clawd 里照着 ~/.codex/... 找文件只会得到"不存在"。

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:

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:

Ecomode Routing Rules

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

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
delegate(role="executor", tier="LOW", task="...")
delegate(role="explore", tier="LOW", task="...")
delegate(role="architect", tier="LOW", task="...")

// FALLBACK - Only if LOW fails
delegate(role="executor", tier="STANDARD", task="...")
delegate(role="architect", tier="STANDARD", task="...")

// AVOID - Only for planning/critique if essential
delegate(role="planner", tier="THOROUGH", task="...")

Delegation Enforcement

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

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 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"))
