Gnhf
Good Night, Have Fun. Make ONE provably-correct, complexity-reducing change on a fresh branch off the default branch, then stop. USE THIS SKILL when the user types /gnhf, asks for a single low-risk independently-reviewable improvement, mentions "overnight" or "unattended" code work, wants to wrap autopilot around a bounded single-iteration prompt, or asks for one small provable cleanup that should be isolated on its own branch. Do NOT use this skill for broad cleanup, fix-all-tests sweeps, multi-file modernization, exploratory refactoring, or anything the user expects to span more than one reviewable branch.

From the source SKILL.md
Inspired by [gnhf](https://github.com/kunchenguid/gnhf), but stripped down: one prompt, one change, one branch, then stop. No loop, no orchestration. To run overnight, wrap this in autopilot or an external scheduler that invokes /gnhf repeatedly — every invocation produces an independent, reviewable branch.
What this skill does
Gnhf is a community-contributed Claude Code skill in the code-quality sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/gnhf/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Gnhf Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Gnhf skill?
Use Gnhf when your Claude Code task falls under the Engineering category — specifically in the code quality area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Gnhf" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Gnhf skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Gnhf is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
