# Evolve reusable coding-agent skills from failed trajectories with EvoSkill

Mine failed agent runs for reusable skills, benchmark the candidates, and keep only the variants that improve a supported coding agent over your baseline.

## Prerequisites

Python environment, a supported coding agent such as Claude Code, OpenCode, OpenHands, Goose, or Codex CLI, and a benchmark or task set to optimize against

## Installation

Use the upstream install or setup path that matches your environment:
- uv sync
- pip install -e .
- brew install --cask claude-code # Claude Code
- brew install opencode # OpenCode (v1.4.0+)

Requirements and caveats from upstream:
- [Python API](#python-api)
- Python 3.12+
