Lenny Skills Plus

中文版: README.zh-CN.md

CI License: Apache-2.0 Skills: 87

A curated library of 87 agent-executable skill packs (86 converted from RefoundAI's "Lenny skills" + 1 meta-skill) that follow the open Agent Skills format. Works with both OpenAI Codex and Claude Code.

Each skill pack defines scope, required inputs, concrete deliverables, a step-by-step workflow, and quality gates — so agents produce reviewable artifacts instead of generic advice.

Quick Usage

In Codex, type $ and pick a skill:

$writing-prds
Turn these notes into a decision-ready PRD. Ask up to 5 questions first.

In Claude Code, invoke with /:

/writing-prds
Turn these notes into a decision-ready PRD. Ask up to 5 questions first.

Install

Option A: From GitHub Release (recommended)

Download skills-all.zip from the latest release and unzip:

# For Codex (global)
mkdir -p ~/.codex/skills && unzip -o skills-all.zip -d ~/.codex/skills

# For Claude Code (global)
mkdir -p ~/.claude/skills && unzip -o skills-all.zip -d ~/.claude/skills

For project-local install, unzip into .codex/skills/ or .claude/skills/ in your repo instead.

git clone https://github.com/liqiongyu/lenny_skills_plus.git
cd lenny_skills_plus

# Global install
mkdir -p ~/.codex/skills ~/.claude/skills
rsync -a skills/ ~/.codex/skills/
rsync -a skills/ ~/.claude/skills/

Or copy into .codex/skills/ / .claude/skills/ in your target repo for project-local install.

Best when you only need 1-5 skills:

$skill-installer
Install `writing-prds` from `liqiongyu/lenny_skills_plus` at `skills/writing-prds`.

Restart Codex after installing.

git clone https://github.com/liqiongyu/lenny_skills_plus.git
cd lenny_skills_plus
python3 scripts/mirror_skills.py --overwrite

This mirrors canonical skills/ into .codex/skills/ and .claude/skills/ for auto-discovery (git-ignored).

Why This Exists

High-level advice is hard for agents to execute reliably. This repo turns skills into execution contracts: inputs → deliverables → workflow → quality gate. See: docs/WHY_THIS_PROJECT.md.
