Skills

3 SKILL.md files ship with this plugin. Preview, copy, or download each one, then install them with the Skills CLI.

Share
skills-cli
  • krypton-execution

    skills/krypton-execution/SKILL.md

    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.

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • krypton-planning

    skills/krypton-planning/SKILL.md

    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.

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • krypton-vps-codex-app

    skills/krypton-vps-codex-app/SKILL.md

    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 setup instructions with proof checks.
