Claude Code plugin that learns reusable skills from your sessions and prunes unused ones.
The short answer
Choose Agentic Awesome Skills if you need…
- Developers using Codex or Claude who want agent-chosen instructions for a project
- Teams that want to review an exact, saved list of skills before installing them
- People who want a local, inspectable workflow instead of a hosted service
- Users comfortable editing config files and running npm or CLI commands
Choose AutoHarness if you need…
- Developers who use Claude Code heavily and repeat the same kinds of tasks
- Teams that want project-level skills to build up without manual upkeep
- People who want to see and control what gets learned, since skills are plain files with a ledger marker

What each one is
Agentic Awesome Skills
Agentic Awesome Skills is a library of installable SKILL.md playbooks, which are instruction files that AI coding agents such as Codex or Claude can read and follow. AAS Core is a local tool that lets the agent search the full catalog, record the skills it chooses, validate that selection, and preview a plan you can review before anything changes. According to the README, Core does not rank or recommend skills itself.
AutoHarness
AutoHarness is a plugin for Claude Code, Anthropic's coding assistant. While you work, it turns useful episodes from your sessions into reusable skill files under .claude/skills/, merges similar skills, updates them as they are used, and removes ones that stop being used. It only manages skills it generated itself and leaves your own or installed skills alone.

- Teams that want to review an exact, saved list of skills before installing them

- People who want to see and control what gets learned, since skills are plain files with a ledger marker
Strengths
Agentic Awesome Skills
- Covers the full catalog locally, so every listed skill can be searched and read
- Keeps a reviewable record of which skills were chosen and why, via manifests and plans
- Explicit dry-run and preview steps before changes are applied
AutoHarness
- Installs as a Claude Code plugin with zero third-party Python dependencies, according to the README
- Only touches skills it wrote itself, so your own skills are not modified
- Tunable cadence and scope through AUTOHARNESS_* environment variables
Not ideal for
Agentic Awesome Skills
- Non-technical users, since setup involves MCP configuration and terminal commands
- People who want the tool to recommend skills for them, because the README says Core does not rank or recommend
- Users who need apply or recovery features in production, since the README says these remain experimental and outside the supported preview
AutoHarness
- Users who do not use Claude Code, since the plugin only runs inside it
- Users on Python older than 3.11 or without python3 on PATH, because hooks silently stay off
- People who want a measured benchmark score for skill quality, since the README says validation comes from use rather than a benchmark
Trade-offs
Agentic Awesome Skills
- The README says apply and recovery are experimental, and it warns that validation does not certify semantic fit or safety to apply
- Setup depends on the Codex or Claude guides and on the README tracking main, so some features may need a later release than the one you install
- The skill count differs across the README and metadata (2,750+, 2,877+), so check the current catalog yourself
AutoHarness
- Requires Python 3.11+ as python3 on PATH; the README warns that older interpreters silently disable the hooks
- The README lists Linux and macOS as the platforms; Windows is not mentioned
- Effectiveness is described as validated by use, not a benchmark, so quality claims are hard to verify independently
