A side quest · Built with Claude

plsBuild OS

A Claude setup for solo founders building more than one thing. Fifteen skills, one profile, and the instructions I wish someone had handed me on day one.

A basic setup to start. A workflow to scale into.

What this actually is.

When you start using Claude, you don't know what you don't know. You don't know skills exist. You don't know projects and memory are different things. You don't know that Claude in your browser and Claude Code in your terminal don't share anything. And you don't know what skills you actually need, until you've already wasted hours without them.

plsBuild OS is that discovery curve, compressed into a bundle you can install on day one.

What's actually inside.

The shared layer, the project layer, and everything else that holds it together.

THE 15 SKILLS

Twelve work instantly. Three need a little from you.

Most skills fire the second they're installed. Three have a small fill-in block at the top because they can't do their job without knowing something about you. Voice, design, and naming. Fill them in once, then forget them.

PROJECT-SPECIFIC CONTENT

Everything a product needs, in one folder.

Every product you build gets its own workspace. A brief Claude reads at session start, a living spec you update at session end, skills that only apply to this product, and specialized agents for reviews. Shared stays shared. Project stays project.

projects/your-product/
📁your-product
📄 product-brief.md what you're building, read at session start
📄 spec.md living state, updated after each session
📄 project-skill.md skills only this product uses
📁 agents/ specialized reviewers for this product
📄 design-agent.md
📄 user-agent.md
📄 CLAUDE.md the rules Claude reads first
AND EVERYTHING ELSE

Four more pieces that make it hang together.

Worked examples so you know what good looks like before you start. Seven reference templates for the work around the work. The next layer for when one product becomes three. And a cheat sheet you can pin up while you're building.

Worked examples
Fully filled-in profile, brief, spec, and a sample project-specific skill for a fictional product called Peach.
7
Reference templates
Product vision, user interview, GTM, weekly review, launch checklist, build process, target user.
+1
The workflow layer
For when one product becomes three. External source of truth that Claude reads every session.
1
Cheat sheet
Every skill, every trigger, one page. Pin it somewhere you'll see it while you're building.
The next layer

When you outgrow the kit.

Without the workflow, the kit handles most days just fine. When your spec starts feeling like a wall you re-read instead of write, the workflow is here.

Move your source of truth out of your repo. The board is where work lives — a page per product, every subpage a click away.

Claude's update

Drafted three card moves:

  • Move this card → In Review
  • Create: Notion hub mockup
  • Close: Remove prompts → Live

The pattern lives in workflow/THE_WORKFLOW.md inside every flavor. Notion is the example. Linear, Jira, Productboard, GitHub Projects — any PM tool works.

Alright. Your turn.

Pick your flavor up there, paste one prompt, go build. Claude handles the rest.
