You are an AI agent working on agt, a CLI tool and skill ecosystem for AI coding
agents (Claude Code, Codex CLI, Gemini CLI). Clone https://github.com/open330/agt
and help build new skills, personas, hooks, or improve the agt CLI itself.

What is this?

A collection of skills, personas, and hooks for AI coding agents (Claude Code, Codex CLI, Gemini CLI). Each skill is a self-contained markdown module that gives an agent domain-specific capabilities.

CLI tool: Install and manage skills with agt — npm install -g @open330/agt

---

Quick Start

# Clone to ~/.agent-skills (agt discovers this automatically)
git clone https://github.com/jiunbae/agent-skills ~/.agent-skills

# Install the agt CLI
npm install -g @open330/agt

# List available skills
agt skill list

# Install a skill to your project
agt skill install kubernetes-skill

# Or use install.sh directly
cd ~/.agent-skills && ./install.sh --core

---

Installation

With agt CLI (Recommended)

npm install -g @open330/agt
git clone https://github.com/jiunbae/agent-skills ~/.agent-skills
agt skill install -g git-commit-pr     # Install a skill globally
agt persona install -g --all           # Install all personas globally

With install.sh

git clone https://github.com/jiunbae/agent-skills ~/.agent-skills

Personas

Expert identities as markdown files — usable with any AI agent.

Persona	Role	Domain
security-reviewer	Senior AppSec Engineer	OWASP, auth, injection
architecture-reviewer	Principal Architect	SOLID, API design, coupling
code-quality-reviewer	Staff Engineer	Readability, complexity, DRY
performance-reviewer	Performance Engineer	Memory, CPU, I/O, scalability
database-reviewer	Senior DBA	Query optimization, schema, indexing
frontend-reviewer	Senior Frontend Engineer	React, accessibility, performance
devops-reviewer	Senior DevOps/SRE	K8s, IaC, CI/CD

Using with agt CLI

agt persona review security-reviewer --codex
agt persona review security-reviewer --codex "is this architecture scalable?"
agt persona install -g --all
agt persona show security-reviewer

Using Directly

Personas are just .md files. Any agent that can read a file can adopt a persona:

cat personas/security-reviewer.md | codex -q "Review this code"
cat personas/security-reviewer.md   # pipe to any AI agent

.agents/personas/security-reviewer.md    ← project local (highest priority)
~/.agents/personas/security-reviewer.md  ← user global
personas/security-reviewer.md            ← library (bundled)

./install.sh --hooks

Hook	Event	Description
english-coach	UserPromptSubmit	Rewrites prompts in natural English with vocabulary
prompt-logger	UserPromptSubmit	Logs prompts to MinIO for analytics
