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
- Keep Step 4 outputs aligned with prior PRD and Tech Design context.
- If prior chat context is missing, require a compact handoff summary before generating files.
- 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
- Look for
docs/PRD-*.md- REQUIRED - Look for
docs/TechDesign-*.md- REQUIRED - If either is missing, suggest running the appropriate skill first
Step 1: Load Context
Handoff Context block? Read it first. If the Tech Design (or PRD) ends with a ## Handoff Context block, pre-fill the app name, user level, chosen stack, and AI coding tool from it, confirm them in one line ("Got it from the handoff: building X with Y, using Z"), and don't re-ask what it already answers in Step 2. No Handoff Context block? Just ask — older documents won't have it.
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)
- Claude Code (terminal-based)
- Gemini CLI (free terminal agent)
- Google Antigravity / equivalent (agent-first IDE)
- Cursor (AI-powered IDE)
- VS Code + GitHub Copilot
- Lovable / v0 (no-code)
Then ask:
What's your technical level?
- A) Vibe-coder
- B) Developer
- C) In-between
Step 3: Instantiate the Templates
This repository ships the canonical templates in /templates/. Read and instantiate them — do NOT write your own versions of these files.
Copy ALL of these into the project root:
| Template | Destination |
|---|---|
| templates/AGENTS.md | AGENTS.md |
| templates/MEMORY.md | MEMORY.md |
| templates/REVIEW-CHECKLIST.md | REVIEW-CHECKLIST.md |
| templates/agent_docs/*.md (all five files) | agent_docs/ |
Then fill every placeholder using the PRD and Tech Design. Templates use exactly two placeholder kinds:
[REPLACE: description]— fill in with project-specific content.[CHOOSE: option A | option B | option C]— pick the ONE matching option and delete the rest.
No square-bracket placeholders may remain when you're done.
Key fills:
- AGENTS.md — Overview & Stack, Setup & Commands from the Tech Design. Tune the existing behavioral sections (
How I Should Think,What NOT To Do,Engineering Constraints) to the user's level — fill, don't create. Fill Roadmap Phase 2 with the PRD's must-have features. Set Current State to "Project setup — nothing built yet". - MEMORY.md — Initialize
## 🏗️ Active Phase & Goalfrom the PRD's Phase 1. - REVIEW-CHECKLIST.md — Copy as-is; it has no placeholders.
- agent_docs/tech_stack.md — Every library, version, and setup command from the Tech Design, plus short canonical code examples.
- agent_docs/code_patterns.md — Resolve the CHOOSE lists (architecture pattern, data fetching, file naming) from the Tech Design.
- agent_docs/project_brief.md — Product vision and conventions.
- agent_docs/product_requirements.md — Complete feature list (MoSCoW), user stories, and success metrics from the PRD.
- agent_docs/testing.md — Test frameworks and commands per the Tech Design.
Resulting structure:

└── (Codex needs nothing — it reads AGENTS.md natively)
Step 4: Generate Tool Configs
AGENTS.md is the universal contract — Codex reads it natively, and most modern agents do too. Tool configs are thin adapters that point at it. Ready-to-copy versions live in templates/tool-adapters/.
| Tool | File | What it is |
|---|---|---|
| Claude Code | CLAUDE.md | 3-line pointer to AGENTS.md + agent_docs/ |
| Codex | — none — | Nothing; AGENTS.md is Codex's native instruction file. Optional: ~/.codex/prompts/ for personal slash prompts |
| Antigravity | .agent/rules/vibe.md | Always-on workspace rule pointing at AGENTS.md |
| Cursor | .cursor/rules/vibe.mdc | Rule with alwaysApply: true pointing at AGENTS.md |
| Any other tool | its custom-instructions feature | "Read AGENTS.md — it is the source of truth for this project." (Gemini CLI users: point it at AGENTS.md the same way.) |
CLAUDE.md (Claude Code)
# CLAUDE.md
Read AGENTS.md first. It is the source of truth for this project: roadmap, commands, rules.
Implementation details live in `agent_docs/` — consult them before coding.
Plan before coding, build one feature at a time, verify before moving on.
.cursor/rules/vibe.mdc (Cursor)
Legacy .cursorrules still loads but is deprecated — delete it if one exists.
---
description: Vibe-coding project rules — source of truth is AGENTS.md
alwaysApply: true
---
Read AGENTS.md first. It is the source of truth: roadmap, commands, rules. Details live in `agent_docs/`.
- Plan before coding; get approval, then build one feature at a time.
- Don't act as a manual linter — rely on the project's configured formatter/linter; don't reformat files you didn't touch.
- Never delete files or change the database schema without confirmation.
.agent/rules/vibe.md (Antigravity)
Current Antigravity reads AGENTS.md natively; this always-on workspace rule reinforces it. Global rules live in ~/.gemini/GEMINI.md.
Read AGENTS.md first. It is the source of truth for this project: roadmap, commands, rules.
Implementation details live in `agent_docs/` — consult them before coding.

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