capability-evolver

capability-evolver is a skill for Claude Code, Codex from leecyno1/boutique-skills. It costs 29 tokens per session (1,321 once invoked), scanned A, a copy of capability-evolver, MIT.

A tool that examines an AI agent’s runtime history, logs, and memory to find failures or inefficient behaviour, then proposes or applies code and memory changes. It can run automatically or pause for human review.

In plain words
What is it for?
Use it to analyse logs, detect crashes, suggest patches, update agent memory, and run repeated improvement cycles from a command or scheduled job.
Why use it?
It helps maintain agents that need to improve after crashes, errors, or repeated inefficient behaviour. Review mode lets a person approve changes before they are applied.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

capability-evolver scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 51 executable files (index.js, scripts/a2a_export.js, scripts/a2a_ingest.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

🧬 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.

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.

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.

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:
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

Environment Variable Default Description
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_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.
EVOLVER_ROLLBACK_MODE hard Rollback 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.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
