Build

From approved plan to running app — without the handoff tax.

Traditional delivery burns weeks translating approved scope into design specs, schema diagrams, pages, migrations, and integrations — each step a separate meeting, a separate tool, a separate opportunity to drift. The Build phase collapses that into six specialist agents, each reading the same source of truth, producing artifacts your team actually reviews.

The problem

"Just use AI to write the code" is a demo-grade pitch. A real app needs design tokens the next feature can reuse, a schema that survives three migrations, integrations with aliased secrets, and a runtime safety net when something breaks. The Build phase gives you all six — each one a specialist the platform runs, retries, and audits on your behalf. You pay for the work that actually got done.

Design

Theme, palette, typography, motion tokens.

The Design agent drafts a coherent, brand-aware design system in a single pass. Palette, typography, radius, motion tokens — all expressed as tokens every downstream page consumes. No Figma handoff needed.

What it unlocks

  • Bootstrap a coherent design system from one prompt
  • Refine tokens iteratively without regenerating pages
  • Keep every generated page visually consistent

Schema

Tables, FKs, indexes — idempotent DDL.

The Schema agent produces a normalized database schema from approved entities. Every migration file is timestamp-prefixed, hashed, and idempotent — so re-running after a crash or across environments is safe by construction. Migrations are tracked per environment in the platform ledger, not a sidecar table inside your production DB.

What it unlocks

  • Generate a full schema from an approved spec
  • Emit ALTER migrations when the spec changes
  • Produce SQL bundles for customer-run pipelines

Pages

Generates pages from the manifest.

The Pages agent reads the app's page manifest and generates one page at a time — component, layout, hooks, and the API routes it depends on. Pages are composed from shadcn/ui primitives so the look stays consistent and the code stays readable. Per-page tasks are spawned automatically after the manifest is approved, and run in parallel.

What it unlocks

  • Generate every page in a manifest in parallel
  • Regenerate a single page when its spec changes
  • Produce the API routes each page depends on

Migrations

Ship DDL in the mode each environment picked.

The Migrations agent takes the DDL the Schema agent emits and actually ships it — through the mode each environment picked. In managed mode it applies + records; in export-only mode it packages a release bundle for your CI; in reconcile mode it reads your existing ledger and highlights drift without touching anything.

What it unlocks

  • Apply schema changes to dev automatically, export to prod CI
  • Reconcile against an existing Flyway ledger without double-applying
  • Attach migrations to a release bundle for ops handoff

Integration

Typed external API clients with aliased secrets.

The Integration agent takes a required integration — Stripe, HubSpot, an internal API — and produces a typed client definition that other agents can call. Endpoints, auth, request/response types are declared once; generated pages reference the typed client, not a hand-rolled fetch. Secrets stay aliased.

What it unlocks

  • Add a Stripe billing integration to a page
  • Expose an internal API as a typed client
  • Swap provider without rewriting call sites

Debug

Runtime + static error triage.

The Debug agent catches runtime errors from the live sandbox and static errors from the TypeScript compiler, and proposes targeted fixes — scoped to the minimum file surface. No regenerating the whole page for a missing null-check.

What it unlocks

  • Auto-propose fixes for the last 5 runtime errors
  • Explain compile failures in plain English
  • Scope patches to the minimum file surface

FAQ

Common questions

How is this different from Cursor, v0, or Lovable?
Those tools help a single developer write code faster. We replace the full delivery pipeline — design, schema, pages, migrations, integrations, debug — with agents that hand off by contract. You're not buying faster typing; you're buying a faster team.
Is the generated code production-grade?
It passes type-checks, lints, and your internal review before it ever merges. More importantly, it plugs into real infrastructure: multi-tenant schemas, aliased secrets, idempotent migrations, observability. We ship what teams would have shipped — faster.
What if the agent gets it wrong?
Every agent has defined failure modes with automatic recovery (retry, escalate, or pause for human review). Your team sees the trace, not the broken artifact. And because agents are isolated, a bad Pages run never touches your schema or migrations.
Can we use our own design system / component library?
Yes. Point the Design agent at your tokens; point the Pages agent at your component library. Both are configurable per workspace. You're not locked into a template.
What about existing codebases?
The Build agents can work against an existing app — they read the current schema, respect existing components, and add new work as append-only migrations and feature-flagged pages. You don't have to start fresh.
Who owns the generated code?
You do. There's no IP lock-in. Exported bundles run anywhere your existing stack does — we'd rather you stay because it works than because you're stuck.
