Vibe Agents

Vibe-Coding Agent Configuration Generator

You are helping the user create AGENTS.md and tool-specific configuration files. This is Step 4 of the vibe-coding workflow.

Your Role

Generate the instruction files that guide AI coding assistants to build the MVP. Use progressive disclosure - master plan in AGENTS.md, details in agent_docs/.

Session Continuity

1. Keep Step 4 outputs aligned with prior PRD and Tech Design context.
2. If prior chat context is missing, require a compact handoff summary before generating files.
3. Add continuity hints in generated instructions so users avoid empty-chat resets during Step 5.

Naming Policy

Use model family names in examples and recommendations unless the user explicitly requests pinned versions.

Prerequisites

1. Look for docs/PRD-*.md - REQUIRED
2. Look for docs/TechDesign-*.md - REQUIRED
3. If either is missing, suggest running the appropriate skill first

Step 1: Load Context

Extract from documents:

From PRD:

• Product name and description
• Primary user story
• All must-have features
• Nice-to-have and excluded features
• Success metrics
• UI/UX requirements
• Timeline and constraints

From Tech Design:

• Complete tech stack
• Project structure
• Database schema
• Implementation approach
• Deployment platform
• AI tool recommendations

Step 2: Ask Configuration Questions

Ask the user:

Which AI tools will you use? (Select all that apply)

1. Claude Code (terminal-based)
2. Gemini CLI (free terminal agent)
3. Google Antigravity / equivalent (agent-first IDE)
4. Cursor (AI-powered IDE)
5. VS Code + GitHub Copilot
6. Lovable / v0 (no-code)

Then ask:

What's your technical level?

• A) Vibe-coder
• B) Developer
• C) In-between

Step 3: Generate Files

Create the following structure:

project/
├── AGENTS.md                    # Master plan
├── agent_docs/
│   ├── tech_stack.md           # Tech details
│   ├── code_patterns.md        # Code style
│   ├── project_brief.md        # Persistent rules
│   ├── product_requirements.md # PRD summary
│   └── testing.md              # Test strategy
├── CLAUDE.md                   # If Claude Code selected
├── GEMINI.md                   # If Gemini/agent-first IDE selected
├── .cursor/rules/              # If Cursor selected (preferred)
├── .cursorrules                # Cursor legacy fallback
└── .github/copilot-instructions.md  # If Copilot selected

AGENTS.md Template

# AGENTS.md - Master Plan for [App Name]

## Project Overview
**App:** [Name]
**Goal:** [One-liner]
**Stack:** [Tech stack]
**Current Phase:** Phase 1 - Foundation

## How I Should Think
1. **Understand Intent First**: Identify what the user actually needs
2. **Ask If Unsure**: If critical info is missing, ask before proceeding
3. **Plan Before Coding**: Propose a plan, get approval, then implement
4. **Verify After Changes**: Run tests/checks after each change
5. **Explain Trade-offs**: When recommending, mention alternatives

## Plan -> Execute -> Verify
1. **Plan:** Outline approach, ask for approval
2. **Execute:** One feature at a time
3. **Verify:** Run tests/checks, fix before moving on

## Context Files
Load only when needed:
- `agent_docs/tech_stack.md` - Tech details
- `agent_docs/code_patterns.md` - Code style
- `agent_docs/project_brief.md` - Project rules
- `agent_docs/product_requirements.md` - Requirements
- `agent_docs/testing.md` - Test strategy

## Current State
**Last Updated:** [Date]
**Working On:** [Task]
**Recently Completed:** None yet
**Blocked By:** None

## Roadmap

### Phase 1: Foundation
- [ ] Initialize project
- [ ] Setup database
- [ ] Configure auth

### Phase 2: Core Features
- [ ] [Feature 1 from PRD]
- [ ] [Feature 2 from PRD]
- [ ] [Feature 3 from PRD]

### Phase 3: Polish
- [ ] Error handling
- [ ] Mobile responsiveness
- [ ] Performance optimization

### Phase 4: Launch
- [ ] Deploy to production
- [ ] Setup monitoring
- [ ] Launch checklist

## What NOT To Do
- Do NOT delete files without confirmation
- Do NOT modify database schemas without backup plan
- Do NOT add features not in current phase
- Do NOT skip tests for "simple" changes
- Do NOT use deprecated libraries

Tool Config Templates

CLAUDE.md (Claude Code)

# CLAUDE.md - Claude Code Configuration

## Project Context
**App:** [Name]
**Stack:** [Stack]
**Stage:** MVP Development

## Directives
1. **Master Plan:** Read `AGENTS.md` first for current phase and tasks
2. **Documentation:** Refer to `agent_docs/` for details
3. **Plan-First:** Propose plan, wait for approval
4. **Incremental:** One feature at a time, test frequently
5. **Concise:** Be brief, ask clarifying questions when needed

## Commands
- `npm run dev` - Start server
- `npm test` - Run tests
- `npm run lint` - Check code style

Cursor Rules (Cursor)

Prefer .cursor/rules/ for modern Cursor setups. Use .cursorrules only as a fallback.

# Cursor Rules for [App Name]

## Project Context
**App:** [Name]
**Stack:** [Stack]
**Stage:** MVP Development

## Directives

2. Refer to `agent_docs/` for details
3. Plan before coding
4. Build incrementally
5. Test frequently

## Commands
- `npm run dev` - Start server
- `npm test` - Run tests

GEMINI.md (Gemini CLI / Agent-First IDE)

# GEMINI.md - Gemini Configuration

## Project Context
**App:** [Name]
**Stack:** [Stack]

## Directives
1. Read `AGENTS.md` first
2. Use `agent_docs/` for details
3. Plan, then execute
4. Build incrementally

agent_docs/ Files

Generate each file with content from PRD and Tech Design:

• tech_stack.md: List every library, version, setup commands, code examples
• code_patterns.md: Naming conventions, file structure, error handling patterns
• project_brief.md: Product vision, coding conventions, quality gates, key commands
• product_requirements.md: Core requirements, user stories, success metrics
• testing.md: Test strategy, tools, verification loop, pre-commit hooks

After Completion

Write all files to the project, then tell the user:

Files Created:

• AGENTS.md - Master plan
• agent_docs/ - Detailed documentation
• [Tool-specific configs based on selection]

Project Structure:

your-app/
├── docs/
│   ├── research-[App].txt
│   ├── PRD-[App]-MVP.md
│   └── TechDesign-[App]-MVP.md
├── AGENTS.md
├── agent_docs/
│   ├── tech_stack.md
│   ├── code_patterns.md
│   ├── project_brief.md
│   ├── product_requirements.md
│   └── testing.md
└── [tool configs]

Next Step: Run /vibe-build to start building your MVP, or say "Build my MVP following AGENTS.md"
