vibe coding setup: configuring AI agents for your workflow

Vibe coding was named word of the year for good reason. The shift from writing every line of code to describing what you want in natural language — and having an AI actually build it — is genuinely transformative. 92% of US developers now use AI coding tools daily. Most of them have experienced at least some version of the vibe coding workflow.

But here’s what separates a frustrating vibe coding experience from a productive one: configuration.

Vibe coding with a misconfigured AI agent is like pair programming with a smart engineer who doesn’t know your codebase, doesn’t understand your conventions, and keeps suggesting patterns your team abandoned months ago. Smart, but constantly wrong in ways that slow you down.

Get the configuration right, and vibe coding becomes what it’s supposed to be — fast, accurate, and actually aligned with how your project works.

What vibe coding actually demands from your agent

Traditional AI-assisted coding is mostly reactive: you write code, the AI suggests completions or answers questions. Vibe coding is more directive: you describe an outcome, the AI figures out the implementation.

This inversion makes configuration dramatically more important. When you ask your agent to “add authentication to this app,” it needs to know:

Which auth library your team uses (not whatever it defaults to)
Where your database layer lives (not wherever it decides to put it)
How you handle errors (not the way the training data showed most often)
What your naming conventions are (not generic names)
Which files it’s allowed to modify (not anything it thinks is relevant)

Without this context, the agent implements its best guess at what “authentication” looks like in a generic project. With good configuration, it implements authentication the way your project does it.

The configuration stack for vibe coding

A vibe coding setup typically has three layers:

1. Universal project context (AGENTS.md)

The foundation. Everything your AI agents need to understand about your project, regardless of which tool they use.

# Project

[Brief description of what the project does and its main domain]

# Stack

[Every technology you use. Be specific — "React" is not enough, "React 19 with Server Components" is.]

# Architecture

[Your folder structure and what lives where. The agent needs to know where to put things.]

# Conventions

[How your team writes code. The more specific, the better.]

# Commands

[How to build, test, lint, and run the project.]

# Do not

[The anti-patterns specific to your project. What mistakes does the AI keep making?]

2. Tool-specific configuration

Layer on top of AGENTS.md to handle platform-specific behavior.

For Claude Code (CLAUDE.md):

See AGENTS.md for project context.

## Before completing any task

- Run tests: `pnpm test`
- Check types: `pnpm check`
- Lint: `pnpm lint`

## For vibe coding tasks

When implementing a new feature:
1. Show me the plan first (files to create/modify, approach)
2. Wait for approval before writing code
3. Implement in small, reviewable chunks
4. Run tests after each chunk

For Cursor, add rules targeting specific file types and contexts. For Copilot, add workspace instructions that set behavioral expectations.

3. Task-level context

Even with great project configuration, complex vibe coding tasks benefit from explicit task context in your prompt. A few extra sentences upfront saves multiple correction rounds.

Less effective:

“Add a notifications system”

More effective:

“Add a notifications system. Use our existing Notification model in lib/db/notifications.ts. Follow the pattern in lib/email/send.ts for the delivery layer. Notifications should be dismissable and persist across sessions.”

Configuring for common vibe coding workflows

Feature development

The most common vibe coding pattern: describe a feature, let the agent build it.

What your config needs:

Explicit folder structure (where do new features live?)
Naming conventions (how do you name components, hooks, utilities?)
What “done” means (tests written? types correct? lint passing?)
Which patterns to follow (does the agent know your existing patterns to replicate?)

Add this to your config:

# Feature development

New features follow this structure:
- UI components: `src/components/features/[feature-name]/`
- Business logic: `src/lib/[feature-name]/`
- API layer: `app/api/[feature-name]/route.ts`
- Types: co-located with the code that uses them

Every new feature must include:
- TypeScript types for all function parameters and return values
- Error handling for all async operations
- Unit tests for business logic in `src/lib/`

Refactoring

Vibe coding for refactoring requires extra guardrails. The agent needs to know what it can touch.

# Refactoring guidelines

When refactoring:
- Preserve existing behavior unless explicitly told otherwise
- Run tests after every change to catch regressions
- Don't rename public API methods or exported types without confirmation
- Change one thing at a time — small, testable steps

Debugging

Configure your agent to be a useful debugging partner:

# Debugging

When investigating a bug:
1. Read the error message and stack trace carefully
2. Identify the specific file and line where the failure occurs
3. Propose a hypothesis before making any changes
4. Verify the fix with the relevant test or a new test
5. Check for similar patterns elsewhere in the codebase

The vibe coding review loop

Even with great configuration, vibe coding produces output that needs review. Build a lightweight review loop into your workflow:

Describe the task with enough context for the agent to understand scope
Review the plan before implementation starts (especially for anything touching more than 3 files)
Check the output against your actual requirements
Run the tests — always
Refine the config if the agent made systematic mistakes

That last step is the one people skip, and it’s where the compound value is. Every systematic mistake the agent makes is a missing or weak instruction in your config. Add it. Your next task starts with a better-configured agent.

Using spaget to manage vibe coding configs

If you’re using multiple AI tools in your vibe coding workflow (which most developers are), keeping your agent configurations in sync becomes its own job.

spaget lets you build your agent configuration once — with the project context, conventions, and behavioral guidelines that make vibe coding work well — and export to Claude Code, Cursor, and GitHub Copilot in one click. When your conventions change, update once and re-export everything.

No account required. Open the builder and see how a well-configured agent changes the vibe coding experience.

The bottom line

Vibe coding is genuinely fast. But “genuinely fast” requires a well-configured AI agent. Without proper configuration, you spend the time you saved on completions correcting outputs that don’t match your project’s patterns.

The investment is small: an hour to write a thorough AGENTS.md and tool-specific configs. The return is every vibe coding session that follows actually working with your project instead of against it.
