Install

Skills CLI

npx skills add asteroid-belt/skulto

Asks which skills and agents to install. Just one: npx skills add asteroid-belt/skulto --skill autobuild — add -g for every project.

Claude Code

git clone https://github.com/asteroid-belt/skultocp -r "skulto/.claude/skills/autobuild" ~/.claude/skills/

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

Plugin

/plugin marketplace add asteroid-belt/skulto

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.

  • autobuild

    Autonomous single-shot plan execution. Runs entire superplan implementation plans without stopping, using sub-agents for each phase. Phases write state to filesystem for resume capability. Sequential phases run in order, parallel phases (1a, 1b) run concurrently. User never needs to compact context.

    .claude/skills/autobuild/SKILL.md on GitHub (opens in a new tab)

  • golang-cli-review

    Comprehensive code review for Golang CLI applications. Produces an actionable checklist covering error handling, CLI framework patterns (Cobra/urfave), testing, performance, security, and Go idioms. TRIGGERS: Review Go CLI, review golang command-line, code review .go CLI, audit CLI application, check golang tool, review cobra app

  • skulto-release-cert

    Certify a skulto build for Homebrew prod release. Runs three passes — unit/lint/cross-compile, clean-slate CLI walkthrough, and security audit — then produces a certification summary.

    .claude/skills/skulto-release-cert/SKILL.md on GitHub (opens in a new tab)

  • superbuild

    Use when executing implementation plans phase-by-phase with strict enforcement of quality gates, tests, and Definition of Done. Triggers on "build this plan", "execute plan", "implement phases", or when user provides a plan document to execute.

    .claude/skills/superbuild/SKILL.md on GitHub (opens in a new tab)

  • superplan

    Use when starting significant features, epics, or complex tasks. Creates multi-phase implementation plans with parallelizable phases, poker estimates, TDD-first acceptance criteria, and quality gates. Detects tech stack from CLAUDE.md/AGENTS.md (bypassing internet research if complete) or via codebase scan.

  • teach

    Transforms technical documents into rigorous learning journeys with collegiate-level mastery requirements. Uses Bloom's taxonomy progression, 80%+ mastery thresholds, and multi-level verification before advancing. Treats learning as a high school to college graduation progression. Use when user wants deep understanding, not surface familiarity.

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.
