Install

Skills CLI

npx skills add jturntdev/krypton

Asks which skills and agents to install. Just one: npx skills add jturntdev/krypton --skill krypton-execution — add -g for every project.

Claude Code

git clone https://github.com/jturntdev/kryptoncp -r "krypton/skills/krypton-execution" ~/.claude/skills/

Copies the krypton-execution skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add jturntdev/krypton

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • krypton-execution

    Use when executing an approved Krypton plan, GOAL.md, or implementation plan that already defines intent, ownership, contract, cutover, task boundaries, and acceptance evidence. Use for main-agent execution with explorer, plan-reviewer, reviewer, maintainer, or verifier gates.

  • krypton-planning

    Use when a user has a feature request, bugfix, refactor, migration, architecture change, or product goal and needs an implementation plan before coding. Use especially when wrong ownership, duplicate paths, stale contracts, weak evidence, or unclear cutover would make plausible agent work dangerous.

  • krypton-vps-codex-app

    Set up, harden, audit, or explain a Linux VPS as a Codex App SSH host for Krypton-style agent workflows. Use when the user wants to move Codex or Claude Code work from a local Mac to a VPS, connect Codex App to an SSH host, configure Ubuntu 24.04/devbox tools, clone a repo remotely, run Codex/Claude/tmux/cmux on the VPS, forward ports for localhost testing, or create repeatable founder/builder se…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
