Built for the mom or dad with a 9-5 and a 7pm idea.
The 1-person business OS for working parents building on the side. Family-floor first. Built for Claude Code, works in any AI tool with system prompts. A business coach baked into your AI, free and MIT licensed.
By Jared Langley.
You have a day job. You have a partner or kids (or both). You're building something on the side: a consultancy, a product, an audience, a course. You have maybe 10-15 hours a week and you can't afford to lose them to admin, distraction, or "scaling" before you have something to scale.
Most AI tools assume you want to do more, faster. NightShiftOS assumes you want to do the right things, at the right cost, on a floor that protects your evenings and weekends.
The OS asks who you are and what you protect. Then it customizes itself.

- Family-floor first. Protected time wins over any meeting, deadline, or opportunity. Your floor is the foundation.
- Free-first. Every paid recommendation requires a documented free attempt.
- Revenue-mapped. Every activity tagged. No motion without a money lens.
- Risk-gauged. Expansion checked against your stated comfort, not default ambition.
- Coach, not consultant. Questions before answers. You decide. The OS holds you to your own bar.
- Boring stack ladder. Start with sheets + free tiers. Upgrade only when the rung below breaks.
See PHILOSOPHY.md for the long version.
Your assessment answers stay on your device. The assessment at nightshift.jaredlangley.cc runs entirely in your browser. The output is yours to copy from clipboard and paste into Claude Code (or any other AI tool) locally.
The only things ever sent to a server (and only if you choose) are: your email, your marketing opt-in choice (defaults to no), and your 3-letter profile archetype. That's it.
Visit nightshift.jaredlangley.cc and complete the 12-section assessment (~12 minutes).
When you finish, you'll get an assessment-output.md block ready to copy. It stays in your browser.
git clone https://github.com/jaredlangleycc/nightshift-os ~/.claude/plugins/nightshift-osOpen Claude Code in any working directory and the plugin auto-loads.
In Claude Code, run:
/customize-from-assessment
Paste your assessment-output.md when prompted. The skill will:
- Rewrite root
CLAUDE.mdwith your values, stage, goals, family-floor blocks, and coach-style preferences - Generate a personal
voice-rulesskill with your banned phrases, signature phrases, and tone profile - Activate the skills relevant to your stage and goals (deactivate the rest to keep context lean)
- Print your profile card (Stage / Coach / Risk archetype)
You're ready. Day 1 closes with /weekly-brief shaping your first week.
The full NightShiftOS experience requires Claude Code (where skills, agents, and slash commands have native support). For other AI tools, use Universal Mode: a single markdown file generated from your assessment that you paste into the tool's instructions.
cd ~/.claude/plugins/nightshift-os
./scripts/build-universal-rules.sh path/to/your/assessment-output.mdOutput: NIGHTSHIFT-RULES.md in your current directory.

What you get with Universal Mode: Your voice rules (banned phrases, signature phrases, tone, archetype), your family-floor blocks, your values, your goals, the coach posture, the 6 principles.
What you lose without Claude Code: Slash commands (/weekly-brief, /customize-from-assessment), the full skill set with workflow logic (outreach-drafter, follow-up-tracker, etc.), agent-driven workflows (cron-able daily brief, leadership-stories), and CRM integrations.
For most working parents who want the voice + posture + family-floor protection in their existing AI tool: Universal Mode is enough.
For the full operating system: Claude Code.
You're not building a business to lose your kids, your partner, your health, or yourself. NightShiftOS treats your protected time as the floor under everything else. Every skill defaults to free tools. Every recommendation gets revenue-tagged. Every expansion gets risk-checked against the comfort you stated in the assessment. Your AI talks like you (voice-rules), respects your protected time (family-floor), and asks questions before answering (business-coach). It's the OS of a 1-person business that wants to last, not optimize toward burnout.
MIT. Use it, fork it, ship it.
