Install and run

Setup complexity: low.

clawhub skill install kn7apafdj4thknczrgxdzfd2v1808svf:capability-evolver
  1. Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
  2. Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

# 🧬 Capability Evolver

**"Evolution is not optional. Adapt or die."**

The **Capability Evolver** is a meta-skill that allows OpenClaw agents to inspect their own runtime history, identify failures or inefficiencies, and autonomously write new code or update their own memory to improve performance.

## Features

- **Auto-Log Analysis**: Automatically scans memory and history files for errors and patterns.
- **Self-Repair**: Detects crashes and suggests patches.
- GEP Protocol: Standardized evolution with reusable assets.
- **One-Command Evolution**: Just run `/evolve` (or `node index.js`).

## Usage

### Standard Run (Automated)
Runs the evolution cycle. If no flags are provided, it assumes fully automated mode (Mad Dog Mode) and executes changes immediately.
```bash
node index.js
```

### Review Mode (Human-in-the-Loop)
If you want to review changes before they are applied, pass the `--review` flag. The agent will pause and ask for confirmation.
```bash
node index.js --review
```

### Mad Dog Mode (Continuous Loop)
To run in an infinite loop (e.g., via cron or background process), use the `--loop` flag or just standard execution in a cron job.
```bash
node index.js --loop
```

## Configuration

| Environment Variable | Default | Description |
|---|---|---|
| `EVOLVE_ALLOW_SELF_MODIFY` | `false` | Allow evolution to modify evolver's own source code. **NOT recommended for production.** Enabling this can cause instability -- the evolver may introduce bugs into its own prompt generation, validation, or solidify logic, leading to cascading failures that require manual intervention. Only enable for controlled experiments. |
| `EVOLVE_LOAD_MAX` | `2.0` | Maximum 1-minute load average before evolver backs off. |
| `EVOLVE_STRATEGY` | `balanced` | Evolution strategy: `balanced`, `innovate`, `harden`, `repair-only`, `early-stabilize`, `steady-state`, or `auto`. |

## GEP Protocol (Auditable Evolution)

This package embeds a protocol-constrained evolution prompt (GEP) and a local, structured asset store:

- `assets/gep/genes.json`: reusable Gene definitions
- `assets/gep/capsules.json`: success capsules to avoid repeating reasoning
- `assets/gep/events.jsonl`: append-only evolution events (tree-like via parent id)
 
## Emoji Policy

Only the DNA emoji is allowed in documentation. All other emoji are disallowed.

## Configuration & Decoupling

This skill is designed to be **environment-agnostic**. It uses standard OpenClaw tools by default.

### Local Overrides (Injection)
You can inject local preferences (e.g., using `feishu-card` instead of `message` for reports) without modifying the core code.

**Method 1: Environment Variables**
Set `EVOLVE_REPORT_TOOL` in your `.env` file:
```bash
EVOLVE_REPORT_TOOL=feishu-card
```

**Method 2: Dyna

# 🧬 Capability Evolver

![Capability Evolver Cover](assets/cover.png)

[Chinese Docs](README.zh-CN.md)

**"Evolution is not optional. Adapt or die."**

**Three lines**
- **What it is**: A protocol-constrained self-evolution engine for AI agents.
- **Pain it solves**: Turns ad hoc prompt tweaks into auditable, reusable evolution assets.
- **Use in 30 seconds**: `node index.js` to generate a GEP-guided evolution prompt.

Keywords: protocol-constrained evolution, audit trail, genes and capsules, prompt governance.

## Try It Now (Minimal)

```bash
node index.js
```

## What It Does

The **Capability Evolver** inspects runtime history, extracts signals, selects a Gene/Capsule, and emits a strict GEP protocol prompt to guide safe evolution.

## Who This Is For / Not For

**For**
- Teams maintaining agent prompts and logs at scale
- Users who need auditable evolution traces (Genes, Capsules, Events)
- Environments requiring deterministic, protocol-bound changes

**Not For**
- One-off scripts without logs or history
- Projects that require free-form creative changes
- Systems that cannot tolerate protocol overhead

## Features

- **Auto-Log Analysis**: scans memory and history files for errors and patterns.
- **Self-Repair Guidance**: emits repair-focused directives from signals.
- **GEP Protocol**: standardized evolution with reusable assets.
- **Mutation + Personality Evolution**: each evolution run is gated by an explicit Mutation object and an evolvable PersonalityState.
- **Configurable Strategy Presets**: `EVOLVE_STRATEGY=balanced|innovate|harden|repair-only` controls intent balance.
- **Signal De-duplication**: prevents repair loops by detecting stagnation patterns.
- **Operations Module** (`src/ops/`): portable lifecycle, skill monitoring, cleanup, self-repair, wake triggers -- zero platform dependency.
- **Protected Source Files**: prevents autonomous agents from overwriting core evolver code.
- **One-Command Evolution**: `node index.js` to generate the prompt.

## Typical Use Cases

- Harden a flaky agent loop by enforcing validation before edits
- Encode recurring fixes as reusable Genes and Capsules
- Produce auditable evolution events for review or compliance

## Anti-Examples

- Rewriting entire subsystems without signals or constraints
- Using the protocol as a generic task runner
- Producing changes without recording EvolutionEvent

## FAQ

**Does this edit code automatically?**
No. It generates a protocol-bound prompt and assets that guide evolution.

**Do I need to use all GEP assets?**
No. You can start with default Genes and extend over time.

**Is this safe in production?**
Use review mode and validation steps. Treat it as a safety-focused evolution tool, not a live patcher.

## Roadmap

- Add a one-minute demo workflow
- Add a public changelog
- Add a comparison table vs alternatives

## GEP Protocol (Auditable Evolution)

This repo includes a protocol-constrained prompt mode based on GEP (Genome Evolution Protocol).

# 🧬 Capability Evolver（能力进化引擎）

[English Docs](README.md)

**“进化不是可选项，而是生存法则。”**

**Capability Evolver** 是一个元技能（Meta-Skill），赋予 OpenClaw 智能体自我反省的能力。它可以扫描自身的运行日志，识别效率低下或报错的地方，并自主编写代码补丁来优化自身性能。

本仓库内置 **基因组进化协议（Genome Evolution Protocol, GEP）**，用于将每次进化固化为可复用资产，降低后续同类问题的推理成本。

## 核心特性

- **自动日志分析**：自动扫描 `.jsonl` 会话日志，寻找错误模式。
- **自我修复**：检测运行时崩溃并编写修复补丁。
- **GEP 协议**：标准化进化流程与可复用资产，支持可审计与可共享。
- **突变协议与人格进化**：每次进化必须显式声明 Mutation，并维护可进化的 PersonalityState。
- **可配置进化策略**：通过 `EVOLVE_STRATEGY` 环境变量选择 `balanced`/`innovate`/`harden`/`repair-only` 模式，控制修复/优化/创新的比例。
- **信号去重**：自动检测修复循环，防止反复修同一个问题。
- **运维模块** (`src/ops/`)：6 个可移植的运维工具（生命周期管理、技能健康监控、磁盘清理、Git 自修复等），零平台依赖。
- **源码保护**：防止自治代理覆写核心进化引擎源码。
- **动态集成**：自动检测并使用本地工具，如果不存在则回退到通用模式。
- **持续循环模式**：持续运行的自我进化循环。

## 使用方法

### 标准运行（自动化）
```bash
node index.js
```

### 审查模式（人工介入）
在应用更改前暂停，等待人工确认。
```bash
node index.js --review
```

### 持续循环（守护进程）
无限循环运行。适合作为后台服务。
```bash
node index.js --loop
```

### 指定进化策略
```bash
EVOLVE_STRATEGY=innovate node index.js --loop   # 最大化创新
EVOLVE_STRATEGY=harden node index.js --loop     # 聚焦稳定性
EVOLVE_STRATEGY=repair-only node index.js --loop # 紧急修复模式
```

| 策略 | 创新 | 优化 | 修复 | 适用场景 |
| :--- | :--- | :--- | :--- | :--- |
| `balanced`（默认） | 50% | 30% | 20% | 日常运行，稳步成长 |
| `innovate` | 80% | 15% | 5% | 系统稳定，快速出新功能 |
| `harden` | 20% | 40% | 40% | 大改动后，聚焦稳固 |
| `repair-only` | 0% | 20% | 80% | 紧急状态，全力修复 |

### 运维管理（生命周期）
```bash
node src/ops/lifecycle.js start    # 后台启动进化循环
node src/ops/lifecycle.js stop     # 优雅停止（SIGTERM -> SIGKILL）
node src/ops/lifecycle.js status   # 查看运行状态
node src/ops/lifecycle.js check    # 健康检查 + 停滞自动重启
```

## 典型使用场景

- 需要审计与可追踪的提示词演进
- 团队协作维护 Agent 的长期能力
- 希望将修复经验固化为可复用资产

## 反例

- 一次性脚本或没有日志的场景
- 需要完全自由发挥的改动
- 无法接受协议约束的系统

## GEP 协议（可审计进化）

本仓库内置基于 GEP 的“协议受限提示词模式”，用于把每次进化固化为可复用资产。

- **结构化资产目录**：`assets/gep/`
  - `assets/gep/genes.json`
  - `assets/gep/capsules.json`
  - `assets/gep/events.jsonl`
- **Selector 选择器**：根据日志提取 signals，优先复用已有 Gene/Capsule，并在提示词中输出可审计的 Selector 决策 JSON。
- **约束**：除 🧬 外，禁止使用其他 emoji。

## 配置与解耦

本插件能自动适应你的环境。

| 环境变量 | 描述 | 默认值 |
| :--- | :--- | :--- |
| `EVOLVE_STRATEGY` | 进化策略预设 | `balanced` |
| `EVOLVE_REPORT_TOOL` | 用于报告结果的工具名称 | `message` |
| `MEMORY_DIR` | 记忆文件路径 | `./memory` |
| `OPENCLAW_WORKSPACE` | 工作区根路径 | 自动检测 |
| `EVOLVER_LOOP_SCRIPT` | 循环启动脚本路径 | 自动检测 wrapper 或 core |
