Stop fighting your AI co-pilot. Automatically audit any repository, resolve complex logic, and deliver a zero-hallucination "Floor Plan" directly to Cursor, Claude, or Replit. Built for Agencies, Solopreneurs, and No-Code Builders.
Zero setup. No credit card required for public audits. Instant billable recovery.
When you ask Claude, Cursor, or Replit to build features without a context file, AI gets confused, invents fake files, and breaks your project.
// AI Prompt Result Without Context:
"Error: Cannot find module '@/lib/db' or file conventions."
CLAUDE.md, .cursorrules, or replit.md files.// GitContextGen Generated Context:
✓ Full Tree Indexed • Rules Active • 0 Hallucinations
You don't need to write code to build software with AI. GitContextGen gives AI tools like Cursor, Replit, or Claude Code the exact map they need to build new features without breaking your existing app.
What happens when you ask AI to code directly
If you hire a brilliant carpenter but don't show them where your electrical wires or plumbing live, they will accidentally break walls or drill into pipes.
When your AI receives your app blueprint
GitContextGen scans your project link in 10 seconds and creates a clear 1-file blueprint. You drop it into your AI tool, and your AI instantly understands your whole project.
See how GitContextGen compares to the alternatives developers are using today — and why most of them leave your AI agent flying blind.
No signup required. Paste a repo URL and see the difference.
Instead of dumping raw code into a prompt, GitContextGen builds a structured Repository Knowledge Model backed by real file evidence.
Extracts exact package scripts (npm dev, pnpm test, make build) directly from package.json, Makefile, and CI workflows.
Maps file trees, route handlers, utility functions, and component boundaries across /src, /app, and /lib.
Detects secrets, .env files, generated build artifacts, and protected paths so AI agents never edit prohibited files.
Compiles the canonical knowledge model into AGENTS.md, CLAUDE.md, .cursorrules, Copilot instructions, and replit.md.
No coding experience needed. Generate instant context files for your AI tool in seconds.

# Project Instructions for Claude
- Enforce Next.js App Router conventions
- Preserve clean TypeScript types across /lib
This is what GitContextGen generates from a single GitHub URL. Detailed architecture, verified commands, safety boundaries, and coding standards — not vague summaries.
# CLAUDE.md — CVGenie AI Resume Generator
> **Generated by**: GitContextGen Knowledge Engine
> **Repository**: `cvgenie/cvgenie-app`
> **Format**: Claude Code / Claude Sonnet
---
## Project Identity
CVGenie is a microSaaS AI-powered resume and cover letter generator.
It uses DeepSeek API to produce ATS-optimized resumes from uploaded
PDFs and pasted job descriptions. React 18 + Express + FastAPI hybrid.
## Verified Execution Commands
```yaml
Dev Server: npm run dev # Starts Vite dev server (port 5173)
API Server: npx tsx server/ # Express API on port 5000
Production Build: npm run build # Vite production bundle
Type Check: npx tsc --noEmit # Full TypeScript validation
```
Evidence: package.json#scripts (verified)

## Protected Files — DO NOT MODIFY
| File | Purpose |
|:-----|:--------|
| server/routes.ts | DeepSeek API integration, ATS formatting, generation endpoint |
| server/documentGenerator.ts | PDF/DOCX/TXT output with free-tier watermarks |
| server/documentParser.ts | Resume parsing via pdfplumber (Python) |
These files handle core AI generation. Any change requires full
end-to-end testing before deployment.
## Safety & Edit Boundaries
- NEVER expose `.env` values (DEEPSEEK_API_KEY, CLERK_SECRET_KEY)
- NEVER modify files in `dist/`, `node_modules/`, or Python `__pycache__/`
- NEVER change AI model names or prompt templates unless explicitly asked
- NEVER remove free-tier watermark logic from documentGenerator.ts
## Coding Standards
- React functional components with TypeScript interfaces for all props
- Forms: React Hook Form + Zod schema validation
- State: TanStack React Query with staleTime: 30000 to reduce refetches
- Auth: Clerk (@clerk/clerk-react for frontend, @clerk/express for API)
- Routing: Wouter (lightweight, client-side)
- Styling: Tailwind CSS + shadcn/ui component librarySample output for cvgenie/cvgenie-app. Your repository produces a unique specification based on its actual file structure and dependencies.
You don't need to read or edit the file yourself. Click each section below to see what it tells your AI tool.
## Run & Operate - npm run dev — starts your local server on port 3000 - npm run build — checks for errors before saving
Without this, AI tools guess how to start your app and run broken commands that freeze your computer screen. This section forces the AI to use the exact right command.

# CLAUDE.md Specification
- Project: App Router & TypeScript
- Directory Tree: Indexed 48 files
GitContextGen scans directory layouts, package dependencies, and file structures automatically.
✓ Scanned 120 source files
✓ Mapped route handlers & utilities
✓ Extracted component conventions
Give AI tools strict project boundaries so they write clean, working code on the first attempt.
[Verified Project Rules]
"AI MUST use existing components from /src/components and preserve TypeScript contracts."
GitContextGen adapts to your workflow — no matter your technical background or team size.
Managing 5+ client repositories
Common Problems
How GitContextGen Helps
Generate verified context files for every client repo in seconds. New team members and AI agents instantly understand architecture, commands, and boundaries — cutting onboarding from days to minutes.
"Vibe coders" & indie hackers
Common Problems
How GitContextGen Helps
Paste your repo URL, get a production-grade specification instantly. Your AI assistant writes correct code on the first try — no more debugging hallucinated imports or deprecated APIs.
Building with AI — no coding background
Common Problems
How GitContextGen Helps
You don't need to understand the technical details. Paste your GitHub link, select your AI tool, and download the context file. Drop it in your project — your AI immediately "gets" your codebase.
No signup required. Results in under 30 seconds.
Static CLAUDE.md and .cursorrules files quickly go out of date after refactors, dependency updates, or route additions.

- Build Command: npm run build (Deprecated)
+ Build Command: pnpm run build --filter=web (Updated via Push Event)
✓ Added route boundary rule: "Validate JSON body in /src/app/api/webhooks"
Inspects git diffs automatically on every commit.
Identifies outdated build commands or new route paths.
Opens a clean Pull Request for your team to merge.
GitContextGen compiles one shared Repository Knowledge Model into native instruction formats for all modern AI tools.
Generates structured specs with overview, commands, and code guidelines.
Official custom instructions adapter for repository-wide Copilot completions.
Strict prompt configuration enforcing project boundaries & framework rules.
Vendor-neutral open format for cross-agent repository readiness.

No mandatory installation. No complex configuration. Pure plain-text context files ready for Claude, Cursor, Replit, or Windsurf.
// Step 1: Paste any public GitHub repo URL
$ gitcontextgen analyze https://github.com/owner/repo
// Step 2: Copy CLAUDE.md, .cursorrules, or replit.md file
✓ Generated CLAUDE.md & .cursorrules context spec
Built from the ground up for strict privacy, read-only repository analysis, and zero lock-in.
Repository file trees and manifests are parsed strictly in-memory during edge execution. Code is never written to disk.
Your source code is never saved to a database or used to train public AI models. Only approved markdown outputs remain in your repo.
Automatic scanning strips API keys, credentials, .env files, and protected paths before generating context instructions.
GitContextGen is read-only by default. Proposed context updates are submitted via Pull Requests for your team to review.
Zero fluff. Choose monthly flexibility or save 15% with annual billing.
Billed annually at $192/year (Saved $36)
For solo developers and no-code builders shipping products with Cursor, Claude, or Replit.
Billed annually at $804/year (Saved $144)
For development agencies managing client projects and multi-repo architectures.
Try GitContextGen risk-free. If your AI coding assistant (Cursor, Claude, or Replit) doesn't produce measurably cleaner code on your first project audit, cancel anytime with a single click.
Clear, detailed answers about AI context files, AGENTS.md, context drift, and code security.
A context file gives AI assistants (like Claude, Cursor, or Copilot) clear instructions about your project structure, build commands, and coding conventions. It acts as a specification manual so AI agents write working code for your specific app without hallucinating or breaking files.
