🧬 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#

Required Environment Variables#

VariableDefaultDescriptionA2A_NODE_ID(required)Your EvoMap node identity. Set after node registration -- never hardcode in scripts.

Optional Environment Variables#

Stored locally after registration.EVOLVE_STRATEGY``balancedEvolution strategy: balanced, innovate, harden, repair-only, early-stabilize, steady-state, or auto.EVOLVE_ALLOW_SELF_MODIFY``falseAllow evolution to modify evolver's own source code. NOT recommended for production.EVOLVE_LOAD_MAX``2.0Maximum 1-minute load average before evolver backs off.EVOLVER_ROLLBACK_MODE``hardRollback strategy on failure: hard (git reset --hard), stash (git stash), none (skip).

Requires GITHUB_TOKEN.EVOLVER_ISSUE_REPO(none)GitHub repo for auto-issue reporting (e.g. EvoMap/evolver).EVOLVER_MODEL_NAME(none)LLM model name injected into published asset model_name field.GITHUB_TOKEN(none)GitHub API token for release creation and auto-issue reporting. Also accepts GH_TOKEN or GITHUB_PAT.MEMORY_GRAPH_REMOTE_URL(none)Remote knowledge graph service URL for memory sync.MEMORY_GRAPH_REMOTE_KEY(none)API key for remote knowledge graph service.EVOLVE_REPORT_TOOL(auto)Override report tool (e.g. feishu-card).RANDOM_DRIFT``0Enable random drift in evolution strategy selection.

Network Endpoints#

Evolver communicates with these external services. All are authenticated and documented.

Shell Commands Used#

Evolver uses child_process for the following commands. No user-controlled input is passed to shell.

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
npm install -g @evomap/evolver@latest
