capability-evolver

capability-evolver is a skill for Claude Code, Codex from anymouschina/TapCanvas. It costs 29 tokens per session (1,071 once invoked), scanned A, original, MIT.

A self-improvement tool for AI agents that examines their past runs to find failures or inefficient steps, then updates code or stored memory.

In plain words
What is it for?
Use it to inspect runtime logs, detect issues, suggest or apply patches, and run an automated or reviewable improvement cycle.
Why use it?
It helps agents learn from crashes and repeated problems instead of relying on the same flawed process each time.

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 49 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

Agents-CLI (This Repository) Recommended

Run from apps/agents-cli:

cd apps/agents-cli
node skills/evolver/index.js run

Optional environment overrides for this runtime:

export AGENT_SESSIONS_DIR="$PWD/.agents/memory/sessions"
export MEMORY_DIR="$PWD/.agents/memory"
export EVOLVE_BRIDGE=false

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 run

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

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.

Files

What ships with it

56 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.

capability-evolver is a skill published in the GitHub repository anymouschina/TapCanvas (590 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 1,071 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
