Vibe Coding to Production with AI Agents

Vibe coding gets an app working; production breaks it. Auth edge cases, schema drift, and out-of-date API contracts surface the moment real users arrive — and adding more AI coding agents multiplies the chaos. The fix is coordination: give every agent the same shared state through tickets, published contracts, and claims, so they work from facts instead of guesses.

If you built an app with an AI app builder — Lovable, Bolt, v0 — or vibe coded it in Cursor over a weekend, you have lived the first half of that story. This post is about the second half: what actually breaks, why adding agents alone doesn't fix it, and how coordination through shared context does.

The vibe-coding honeymoon

Vibe coding works. That's the part the critics get wrong. You describe what you want, the agent writes it, you look at the preview, you describe the next thing. AI app builders have compressed the distance from idea to working demo into an afternoon, and people who would never have written a line of code are now building apps with AI and putting them on real URLs. The loop is fast because the conditions are perfect: one agent, one repo it generated itself, and an app small enough to fit in a context window. The agent holds the entire codebase in its head because it wrote all of it, five minutes ago.

The honeymoon lasts exactly as long as three things stay true: the app stays small, you stay the only user, and one agent does all the writing. Production ends all three at once.

The production wall

Auth gets real. In preview, everything ran as you. In production there are sessions, roles, row-level security policies, and password resets. The agent that confidently scaffolded login for the demo never had to handle an expired token or a user who belongs to two workspaces — and these failures show up at runtime, not at build time.

Schema drift starts. Every change is a migration now. The agent adds a column in one session; a later session, working from an older snapshot of the schema, writes a query against a shape that no longer exists. Generated types lag the database. Nothing fails until a real request hits the wrong assumption.

API contracts diverge. The frontend calls POST /orders/cancel. The backend actually exposes PATCH /orders/{id} with a status field. Both sides compile, both pass their own checks, and the button 404s for your first paying user. Once the frontend and backend live in separate repos — common after you outgrow a single AI app builder project — neither agent can even see the other side.

More hands touch the repo. You bring in a second agent, or a freelancer, or a co-founder. Now two writers are editing one app with no shared picture of what the other just changed. Nothing tells agent B that agent A renamed the endpoint an hour ago.

None of these are model problems. A better model guesses better, but it is still guessing — the information it needs (the real schema, the real contract, the real state of work in flight) is not in its context window, and prompting harder won't put it there.

Why adding more agents makes it worse

The instinct at this point is to scale the thing that got you here: more agents. A backend agent, a frontend agent, one for tests. The agents themselves are genuinely good — see our rundown of the best AI coding agents in 2026 — but an AI coding agent is a fast, confident writer with no memory of what the other writers did. Run several in parallel without coordination and you get duplicated helpers, conflicting migrations, and contract drift in both directions at once, each agent perfectly consistent with its own stale snapshot of the app.

The bottleneck was never typing speed. It's that your agents share no source of truth. Adding writers to a project with no coordination doesn't add throughput; it adds collisions.

The orchestration answer: shared, contract-aware context

Agent orchestration sounds heavyweight; in practice it's a small set of primitives that give every agent the same grounded view of the app. AppHandoff implements them as a hosted Model Context Protocol server at https://api.apphandoff.com/mcp — OAuth 2.1 auth, Streamable HTTP transport — and it works with Claude Code, Cursor, Codex, and any spec-compliant MCP client. Lovable connects through its MCP integration.

Published contracts. Interfaces are published as shared artifacts: the side that owns an endpoint records its shape on the ticket with ticket, and the consuming side reads it with get. An agent asks what an endpoint accepts and gets the published answer, not variable names and stale comments.

Auto-close on merge. GitHub is synced: when a PR merges, AppHandoff reads its closing lines. A merge with Closes HO-123 moves that ticket to validation and closes it once its deploy is recorded, never on a timer; any other mention only links the merge, and an AI guess waits in validation for a person or agent to confirm. The board reflects what actually landed — an agent reads state, not stale intentions.

Handoff tickets. Work lives as tickets (HO-1, HO-2, …) on a shared Kanban with live claims and a validation stage before work goes live. Each agent sees what is claimed, what's ready, and what's still blocked by another ticket. Two agents stop colliding because they're no longer inferring each other's state; they're reading it.

Merge and deploy signals. The board tracks what actually shipped rather than what someone remembered to update: merged PRs are matched against open tickets, and deploy state lands on the ticket that caused it. An agent reads shipped-or-not as data instead of asking you.

The point of all of this is narrow: every agent, and every human, reads the same facts. Orchestration here isn't a scheduler bossing agents around; it's shared state that makes parallel work safe.

A concrete path: Lovable app to production

Say you built the app in Lovable and the demo landed. Here's the coordinated path to production, end to end.

Connect Lovable to AppHandoff through the Lovable MCP integration and link the GitHub repos. File the gap between demo and production as tickets: auth hardening, real data, error states. The board is your baseline — every known gap is visible before it becomes an outage.

Then put your agents to work on claimed tickets. The backend agent claims the auth-hardening tickets, closing the gaps the board surfaced. The frontend agent claims UI work against published contracts instead of guessed ones. QA validates against acceptance criteria, and you supervise from the board rather than from inside every conversation. Before anything ships, deploy checks gate the release.

When you don't need orchestration

Honest answer: a lot of the time. If you're solo, running one agent, and building something you'll throw away — a pitch demo, a weekend experiment, an internal tool for three people — coordination is overhead. Vibe code it, ship it to a preview URL, move on. A no-code AI app builder on its own is the right tool for that job.

Orchestration earns its keep when specific things become true: real users depend on the app, more than one agent or person writes to it, the frontend and backend live in separate repos, or the codebase has outgrown what one context window can hold. One of those signals is survivable. Two or more and you're already paying the coordination tax — in re-explained context and production 404s — you're just paying it without tooling.

Where this leaves you

Vibe coding got you a working app; that part of the workflow is solved. What better prompts won't solve is the gap between a demo and a system that several writers can safely change. That gap closes with shared context — tickets, published contracts, claims, deploy checks — and it's the difference between agents that guess and agents that coordinate. Connect your agents and let them read the same facts you do.
