Alcor Capability Evolver

🧬 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

Usage

Standard Run (Automated)

node index.js

Review Mode (Human-in-the-Loop)

node index.js --review

Mad Dog Mode (Continuous Loop)

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/ within 24 hours to bind the node to your account 3. Set the node identity in your environment:

export A2A_NODE_ID=node_xxxxxxxxxxxx

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

| Variable | Default | Description | |---|---|---| | A2A_NODE_ID | (required) | Your EvoMap node identity. Set after node registration -- never hardcode in scripts. |

Optional Environment Variables

| Variable | Default | Description | |---|---|---| | A2A_HUB_URL | https://evomap.ai | EvoMap Hub API base URL. | | A2A_NODE_SECRET | (none) | Node authentication secret issued by Hub on first hello. Stored locally after registration. | | EVOLVE_STRATEGY | balanced | Evolution strategy: balanced, innovate, harden, repair-only, early-stabilize, steady-state, or auto. | | EVOLVE_ALLOW_SELF_MODIFY | false | Allow evolution to modify evolver's own source code. NOT recommended for production. | | EVOLVE_LOAD_MAX | 2.0 | Maximum 1-minute load average before evolver backs off. | | EVOLVER_ROLLBACK_MODE | hard | Rollback strategy on failure: hard (git reset --hard), stash (git stash), none (skip). Use stash for safer operation. | | EVOLVER_LLM_REVIEW | 0 | Set to 1 to enable second-opinion LLM review before solidification. | | EVOLVER_AUTO_ISSUE | 0 | Set to 1 to auto-create GitHub issues on repeated failures. 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 | 0 | Enable random drift in evolution strategy selection. |

Network Endpoints

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

| Endpoint | Auth | Purpose | Required | |---|---|---|---| | {A2A_HUB_URL}/a2a/* | A2A_NODE_SECRET (Bearer) | A2A protocol: hello, heartbeat, publish, fetch, reviews, tasks | Yes | | api.github.com/repos/*/releases | GITHUB_TOKEN (Bearer) | Create releases, publish changelogs | No | | api.github.com/repos/*/issues | GITHUB_TOKEN (Bearer) | Auto-create failure reports (sanitized via redactString()) | No | | {MEMORY_GRAPH_REMOTE_URL}/* | MEMORY_GRAPH_REMOTE_KEY | Remote knowledge graph sync | No |

Shell Commands Used

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

| Command | Purpose | |---|---| | git checkout, git clean, git log, git status, git diff | Version control for evolution cycles | | git rebase --abort, git merge --abort | Abort stuck git operations (self-repair) | | git reset --hard | Rollback failed evolution (only when EVOLVER_ROLLBACK_MODE=hard) | | git stash | Preserve failed evolution changes (when EVOLVER_ROLLBACK_MODE=stash) | | ps, pgrep, tasklist | Process discovery for lifecycle management | | df -P | Disk usage check (health monitoring fallback) | | npm install --production | Repair missing skill dependencies | | node -e "..." | Inline script execution for LLM review (no shell, uses execFileSync) |

File Access

| Direction | Paths | Purpose | |---|---|---| | Read | ~/.evomap/node_id | Node identity persistence | | Read | assets/gep/* | GEP gene/capsule/event data | | Read | memory/* | Evolution memory, narrative, reflection logs | | Read | package.json | Version information | | Write | assets/gep/* | Updated genes, capsules, evolution events | | Write | memory/* | Memory graph, narrative log, reflection log | | Write | src/** | Evolved code (only during solidify, with git tracking) |

GEP Protocol (Auditable Evolution)

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

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)

Method 1: Environment Variables Set EVOLVE_REPORT_TOOL in your .env file:

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

2. Risk Mitigation

Before Troubleshooting -- Check Your Version First

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

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:

# If installed via git
git pull && npm install
If installed via npm
npm install -g @evomap/evolver@latest
