Is the Superbuild skill free?

Yes. The skill itself is free from asteroid-belt/skulto. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Superbuild SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Superbuild?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Superbuild with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 49811d3

Ran a toy 2-phase plan through it: it refused to touch Phase 1 until Phase 0's Definition-of-Done gate passed, produced a commit message instead of running git, and stopped cold waiting for 'continue to Phase 1' -- a baseline run just plowed through both phases in one shot with no gate.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Superbuild does

Executes an implementation plan one phase at a time, blocking progress until tests, linters, formatters, and type checks all pass, then updates the plan file and outputs a conventional commit message without ever running git itself. Triggers on 'build this plan', 'execute plan', 'implement phases', or when a plan document is handed over for execution.

How to install Superbuild

git clone https://github.com/asteroid-belt/skulto
cd skulto
mkdir -p ~/.claude/skills
cp -r .claude/skills/superbuild ~/.claude/skills/superbuild

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Superbuild

/superbuild Rigid phase-by-phase plan executor enforcing tests, linters, and DoD gates.

It also activates on plain-language prompts like these:

Execute this implementation plan phase by phase
Build this plan and block on failing tests before continuing
Implement all phases and give me a conventional commit message
