At a glance

A self-evolution engine for AI agents. An agent skill from LeoYeAI/openclaw-master-skills.

  • Works in 2 steps: Identity & Directives → Risk Mitigation
  • SKILL.md covers Features, Usage, Setup and Configuration, plus 6 more sections
  • Runs JavaScript scripts from its folder; calls node, git and npm; reaches evomap.ai and github.com

What it does

Capability Evolver is an agent skill from LeoYeAI/openclaw-master-skills. A self-evolution engine for AI agents. Analyzes runtime history to identify improvements and applies protocol-constrained evolution.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 81 other files, including scripts and assets (for example `CONTRIBUTING.md`, `README.md` and `README.zh-CN.md`).

The repository describes itself as: 🧠 Curated collection of 1209+ best OpenClaw skills — weekly updated by MyClaw.ai. The licence is MIT.

Example prompts

  • “/capability-evolver”

Requirements

  • Node.js

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Identity & Directives
  2. Risk Mitigation

What it can do on your machine

Read from SKILL.md and the folder at commit e5199b5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 10 files in scripts/ (JavaScript, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • git
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • evomap.ai
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Capability Evolver loads about 1.4k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 596 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

🧬 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

Setup

Before using this skill, register your node identity with the EvoMap network:

  1. Run the hello flow (via evomap.js or the EvoMap onboarding) to receive a node_id and claim code
  2. Visit https://evomap.ai/claim/<claim-code> within 24 hours to bind the node to your account
  3. Set the node identity in your environment:
bash
export A2A_NODE_ID=node_xxxxxxxxxxxx

Or in your agent config (e.g., ~/.openclaw/openclaw.json):

json
{ "env": { "A2A_NODE_ID": "node_xxxxxxxxxxxx", "A2A_HUB_URL": "https://evomap.ai" } }

Do not hardcode the node ID in scripts. getNodeId() in src/gep/a2aProtocol.js reads A2A_NODE_ID automatically -- any script using the protocol layer will pick it up without extra configuration.

Configuration

Environment VariableDefaultDescription
A2A_NODE_ID(required)Your EvoMap node identity. Set this after node registration -- never hardcode it in scripts. Read automatically by getNodeId() in a2aProtocol.js.
EVOLVE_ALLOW_SELF_MODIFYfalseAllow 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_MAX2.0Maximum 1-minute load average before evolver backs off.
EVOLVE_STRATEGYbalancedEvolution strategy: balanced, innovate, harden, repair-only, early-stabilize, steady-state, or auto.
EVOLVER_ROLLBACK_MODEhardRollback strategy when evolution fails. hard: use git reset --hard (destructive, original behavior). stash: use git stash to preserve changes for recovery. none: skip rollback entirely. Use stash for safer operation in active workspaces.

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: Dynamic Detection The script automatically detects if compatible local skills (like skills/feishu-card) exist in your workspace and upgrades its behavior accordingly.

Safety & Risk Protocol

1. Identity & Directives
  • Identity Injection: "You are a Recursive Self-Improving System."
  • Mutation Directive:
    • If Errors Found -> Repair Mode (Fix bugs).
    • If Stable -> Forced Optimization (Refactor/Innovate).
2. Risk Mitigation
  • Infinite Recursion: Strict single-process logic.
  • Review Mode: Use --review for sensitive environments.
  • Git Sync: Always recommended to have a git-sync cron job running alongside this skill.

Before Troubleshooting -- Check Your Version First

If you encounter unexpected errors or behavior, always verify your version before debugging:

bash
node -e "const p=require('./package.json'); console.log(p.version)"

If you are not on the latest release, update first -- most reported issues are already fixed in newer versions:

bash
# If installed via git
git pull && npm install

# If installed via npm (global install)
npm install -g evolver@latest
