A multi-agent code generation pipeline with a validator in the loop. Eight specialists — PM, UX, Backend, Frontend, Mobile, QA, DevOps, and a build Validator — plan, code, test, and open a pull request on your GitHub.

“Eight agents. One coherent ship.”
Every step is a real artifact: npm install, build, tests, pull request. The output is the evidence.
One sentence. Plain English. "A weather dashboard, React + Node, using OpenWeatherMap." The PM agent extracts the stack contract and plans a task graph with extended thinking.
Eight specialists work in parallel, reading each other's artifacts through a 1M-token context window. Backend sees the UX. QA sees the frontend. Nothing in isolation.
The Integration Validator clones the repo, runs real builds and tests. Failures trigger up to three automatic rework rounds, then the PR lands on your GitHub for review.
Every capability of the underlying model, wired into a multi-agent framework that produces real artifacts.
PM and QA agents reason through architecture, dependencies, and edge cases before writing a single line. Budget up to 8K thinking tokens per plan.
Agent system prompts are cached across tasks. Cache reads bill at Anthropic's published cache price — 10% of normal input cost — so a 15-task project runs around $0.10 instead of $1.
Agents see the whole codebase. Backend reads the frontend. QA analyses the full app. The validator gets full error context during rework.
Repos are created on your GitHub account via OAuth. Every artifact is committed to a feature branch and shipped as a pull request you review.
The Integration Validator clones the repo, runs npm install, builds, tests, and auto-reworks failures up to three times before shipping.
Your Anthropic API key lives in the per-user database. You control the cost, the model, the limits. We never proxy or share keys between users.
Pick from 12 application archetypes (dashboard, kanban, wizard, list-detail, marketplace, profile, editor, reader, player, calculator, form-heavy, split-view), choose a palette and fonts. The Frontend agent renders to it. The Validator's design-fidelity check scores the output across palette, typography, density, and motion — a low dimension fails the build.
The Validator runs npm install --ignore-scripts to close the preinstall supply-chain vector. The subprocess environment is scrubbed of KEY/SECRET/TOKEN/PASSWORD/ANTHROPIC_*/JWT_*/DATABASE_URL before any generated code runs. 300-second timeout per command. User-supplied descriptions are sanitised and wrapped in boundary markers before they reach the model.
