buildanything

One command to build an entire product.

buildanything is a Claude Code plugin that orchestrates 48 specialist AI agents into a full engineering pipeline — from idea to shipped, tested, reviewed code. You describe what you want to build. buildanything handles research, design, architecture, implementation, behavioral testing, and hardening.

Works for both web apps and iOS/Swift apps.

Install

npx buildanything

This installs the plugin and companion tools (agent-browser for behavioral testing, Playwright for E2E).

For iOS builds, run the iOS setup instead:

npx buildanything --ios

This additionally installs XcodeBuildMCP, apple-docs-mcp, and Maestro.

Commands

/build — Full Product Pipeline

Takes an idea and builds it through 8 phases (0–7) with quality gates, three-tier dispatch, per-feature behavioral verification, and a final launch review. iOS builds add a bootstrap phase (-1) for Xcode project + Maestro scaffold.

0. Discover — Scans for existing work, detects project type (web vs iOS), checks prerequisites, replays prior-build learnings.

1. Plan — Interactive brainstorming + 4 parallel research agents (market, tech, user, business) → PRD + product spec (canonical feature inventory: states, transitions, business rules, persona constraints, acceptance criteria) + per-project CLAUDE.md.

2. Architect — 6-architect team (backend, frontend, data, security, accessibility, performance) cross-checking each other → architecture doc + sprint task DAG.

3. Design — Competitive research, brand DNA card, component manifest, per-screen wireframes, living /design-system route, design critic loop targeting 195/240 across 7 DNA axes + 5 craft dimensions.

4. Build — Three-tier dispatch: Product Owner sequences features → Briefing Officer per feature decomposes into structured task briefs → implementers query the graph for spec slices and execute. Per-task verify gate after each.

5. Audit — Three orthogonal layers run in parallel:

   • Track A (engineering reality) — 5 parallel auditors: API contract, performance, accessibility, security, brand drift.
   • Track B (product reality) — one auditor per feature, runs 7 check classes (screen reachability, state coverage, transition firing, business-rule enforcement, happy path, persona walkthrough, manifest wiring) against the live app.
   • Cross-cutting — Playwright E2E for multi-feature journeys, autonomous dogfooding for emergent issues, fake-data detector for hardcoded mocks.

   All findings consolidate at the feedback synthesizer, then route to a fix loop.

6. Launch Review — 5 chapter judges (engineering quality, security, SRE, accessibility, brand) + aggregator that can route back to earlier phases on BLOCK.

7. Ship — Documentation, deployment, learnings capture.

/build a prediction market maker for Polymarket
/build docs/plans/my-design.md --autonomous

For iOS builds, the pipeline automatically routes to a Swift-native flow (SwiftUI, Swift 6.2, SwiftData, iOS 26 SDK).

/idea-sweep — Parallel Research Sweep

5 research agents evaluate an idea in parallel. Outputs a decision brief: GO / PIVOT / INVESTIGATE / KILL.

/idea-sweep AI-powered building code compliance checker

Post-Build Commands

| Command | Use case | |---|---| | /fix | "The submit button doesn't work" — scoped bug fixing with behavioral verification | | /ux-review | "The dashboard feels cramped" — UX audit against the design system | | /add-feature | "Add a pause button" — mini build cycle reusing the locked design system | | /dogfood | "Test everything" — autonomous exploratory testing of the running app | | /verify | "Does it all pass?" — 7-check health check | | /refactor | "Change auth to OAuth" — architect plans, then incremental execution |

How It Works

Single Source of Truth via Graph

Phase 1 produces a canonical product spec (states, transitions, business rules, persona constraints, acceptance criteria). The plugin indexes it into a per-build graph. Phase 2-5 agents query the graph for typed slices instead of paraphrasing source markdown — closing the gap where product context gets lost between phases.

Behavioral Verification

Every UI task is smoke tested after implementation. agent-browser opens the app, clicks buttons, fills forms, and collects evidence: snapshot diffs, network inspection, console errors, annotated screenshots. Track B (Phase 5) extends this to a full per-feature reality check.

Per-Project Brain

Phase 1 generates a CLAUDE.md file in your project root (<200 lines). This becomes auto-loaded context for every agent in subsequent phases — keeping product decisions, persona constraints, and architectural notes accessible without re-reading raw research.

Living Design System

Phase 3 builds DESIGN.md (brand DNA + tokens + component prose) and a rendered /design-system route. Implementation agents reference both; the brand guardian audits the built output against the locked DNA card.

Feedback Loops

• Per-task smoke test fails → fix + re-test (max 2 cycles)
• Phase 5 findings → synthesizer classifies → fix loop → re-verify (max 2 cycles)
• LRR Aggregator says BLOCK → routes back to the originating phase for re-work

Nothing gets logged and ignored.
