auto-evolution

Category: Agent Orchestration / Meta-Skill Version: 0.7.0

Description

Multi-agent auto-evolution system — a coordinator agent drives an autonomous review → execute → audit loop by spawning specialized sub-agents for each role.

This is a meta-skill: it doesn't handle business logic. It orchestrates the loop so complex tasks get completed autonomously with dual quality gates (pre-execution review + post-execution audit).

Architecture (4 Roles)

Why 4 roles?

• Reviewer and Auditor are both quality gates but serve different purposes
• Reviewer ensures the plan is sound before work starts
• Auditor verifies the result matches the plan after work completes
• Executor is pure labor — follows instructions, no judgment needed

Cost control: Only Reviewer and Auditor need strong models. Coordinator and Executor can use cheap models.

Usage:

# Create task (interactive)
node scripts/create-task.js

# Start Reviewer (complex tasks only)
node scripts/start-reviewer.js \x3Ctask-id>

Core Modules

Setup

1. Initialize workspace

mkdir -p evolution/tasks evolution/archive evolution/test-results

2. Create a task

cp skills/auto-evolution/references/task-example.json evolution/tasks/task-001.json
# Edit with your goal and subtasks

3. Configure the coordinator

Option A: Heartbeat (recommended — in your agent's HEARTBEAT.md)

## Evolution Loop
1. Run `node skills/auto-evolution/scripts/heartbeat-coordinator.js`
2. Parse output: if phase=review → spawn Reviewer sub-agent
3. Apply review → if phase=execute → spawn Executor sub-agent
4. Apply execution → if phase=audit → spawn Auditor sub-agent
5. Apply audit → done for this tick

Option B: Cron

openclaw cron add --agent \x3Cyour-agent> \
  --name "evolution-coordinator" \
  --every 5m \
  --session isolated \
  --timeout-seconds 300 \
  --message "Evolution heartbeat: scan and process tasks."

4. (Optional) Configure the monitor

openclaw cron add --agent \x3Cany-agent> \
  --name "evolution-monitor" \
  --every 10m \
  --session isolated \
  --timeout-seconds 120 \
  --message "Run: node skills/auto-evolution/scripts/monitor.js"

5. Configure models (optional)

Edit evolution/config/models.json to customize which models are used for each role:

{
  "roles": {
    "reviewer": "google/gemini-3.1-pro",
    "executor": "aiberm/gpt-5.4",
    "auditor": "google/gemini-3.1-pro",
    "coordinator": "bailian/qwen3.5-plus"
  }
}

Default: Scripts read from this config file. No environment variables needed.

6. Environment variables (optional)

export OPENCLAW_WORKSPACE=/path/to/workspace
export EVOLUTION_TASKS_DIR=/path/to/tasks

How It Works

Full Loop

Coordinator heartbeat
  → finds task (priority: reviewed > executing > pending)
  → if pending: spawn Reviewer → reviewed
  → if reviewed: spawn Executor → executing
  → if executing: spawn Auditor → pending (next) or completed ✅

State Machine

pending → reviewed → executing → pending (next subtask)
                         → completed (all done)
                         → packaged ✅

Key Rules

• One subtask per iteration — keeps cycles fast and reviewable
• Dual quality gates — Reviewer (before) + Auditor (after)
• Only mark completed when all subtasks done
• If Reviewer/Auditor API fails → wait and retry next heartbeat
• Monitor auto-resets tasks stuck > 10 minutes

Task File Format

See references/task-example.json for a complete example.

Required fields:

{
  "task_id": "task-001",
  "status": "pending",
  "goal": "What to build",
  "current_iteration": 0,
  "max_iterations": 10,
  "context": {
    "subtasks": ["Step 1", "Step 2", "Step 3"]
  },
  "history": []
}

CLI Usage

# Scan and output next phase prompt
node scripts/heartbeat-coordinator.js

# Apply review result
node scripts/heartbeat-coordinator.js apply-review task-001.json review.txt

# Apply execution result
node scripts/heartbeat-coordinator.js apply-exec task-001.json exec.txt

# Apply audit result
node scripts/heartbeat-coordinator.js apply-audit task-001.json audit.txt

# Run monitor
node scripts/monitor.js

# Package completed tasks
node scripts/pack-skill.js

Design Philosophy

• 4-role architecture — Coordinator drives, Reviewer/Executor/Auditor specialize
• Dual quality gates — Review before, audit after — never skip either
• Model-agnostic — swap any model for any role
• One subtask per tick — predictable, reviewable, won't timeout
• Self-healing — monitor detects and fixes stuck states
• Cost-efficient — strong models only where judgment matters (Reviewer, Auditor)
