FORMERLY PLAID.BUILD

Builder OS

An operating system for builders. Agent skills that take you from idea to launched product — turning coding agents from autocomplete into disciplined collaborators that ship reviewed, tested work.

The Skills

Every skill is fully standalone — but they chain. Each writes its output to your project's docs/ folder, and downstream skills pick it up automatically.

IDEATE

Idea Generator

Guided discovery of a product idea by mining what you already know or do. Scores candidate directions and sharpens the winner.

product-idea.md

Idea Validator

Pressure-tests an idea before you build — fatal flaws, real competition, your first 10 customers, a 2-week MVP test, and a blunt verdict.

validation-report.md

PLAN & DESIGN

Product Planner

A structured 8-section vision intake, then generates your strategy & brand, a coding-agent-ready spec, and a phased build plan.

product-vision.md, prd.md, product-roadmap.md

Design System

Translates screenshots, mockups, or Figma URLs into a design.md spec — design tokens plus rationale any agent can build from.

design.md

BUILD

Build MVP

Executes the entire roadmap end to end — implementing, testing, and verifying each task in order, opening a PR per phase.

Build Loop

Tighter, review-gated increments for Claude Code, Codex, or Cursor. Nothing ships on “it compiles” — built, reviewed, tested, fixed.

LAUNCH

Launch Checklist

Audits your actual codebase, then writes a plain-English, step-by-step path from “works on my machine” to “customers can use it.”

Build Anything on Autopilot

THE PROBLEM

AI coding agents are fast, but speed without discipline produces features that "compile" rather than features that work. Nothing gets planned, reviewed, or tested end to end — so you end up rewriting, redirecting, and micromanaging every decision, defeating the purpose of building with AI.

WHY BUILDEROS WORKS

BuilderOS encodes the habits of strong product teams — plan-driven work, mandatory review, end-to-end testing, honest reporting — as skills your agent follows automatically. Every skill stands alone, but they chain: each writes its output to your project's docs/ folder, and downstream skills pick those documents up automatically.

How It Works

01

Ideate

Discover a product idea by mining what you already know or do, then pressure-test it before you invest in building — fatal flaws, real competition, your first 10 customers, and a blunt strong / weak / pivot verdict.

02

Plan & Design

A structured vision-intake conversation generates your core product documents — strategy, a coding-agent-ready spec, and a phased roadmap — plus a design system translated from your reference images.

03

Build

Executes the roadmap task by task. Nothing ships on “it compiles” — every increment is built, reviewed, tested end to end, and fixed before the agent reports done. A PR per phase.

04

Launch

Audits your actual codebase — stack, services, env vars, payments, deploy config — then writes a plain-English, step-by-step path from “works on my machine” to “customers can use it.”
