Enhance

AI prompt middleware — upgrades vague developer prompts into production-quality instructions before sending to coding agents.

What it does

Instead of sending build login page directly to Claude/Codex/OpenCode:

1. Scans your project (stack, frameworks, folder structure)
2. Analyzes your intent
3. Finds relevant existing files for context
4. Rewrites the prompt with structure, best practices, and project awareness
5. Sends the enhanced prompt to the AI

Same effort. Dramatically better output.

Installation

Prerequisites

• Node.js 20+
• At least one AI coding tool: Claude Code, OpenCode, or Codex CLI

Option A — No install (npx)

npx @0xdevabir/enhance@latest "build a login page"

Runs directly without installing anything globally. Great for trying it out or if you hit permission errors.

Option B — Global install

npm install -g @0xdevabir/enhance

Permission error (EACCES)? Fix npm's global prefix first, then retry:

mkdir -p ~/.npm-global
npm config set prefix '~/.npm-global'
echo 'export PATH=$HOME/.npm-global/bin:$PATH' >> ~/.zshrc
source ~/.zshrc
npm install -g @0xdevabir/enhance

Step 2 — Run setup

Step 2 — Run setup

enhance setup

Detects which AI coding tools you have installed and automatically adds the /enhance slash command to each one.

Enhance — Setup

Detected: Claude Code, OpenCode
Not found: Codex CLI

✓ Claude Code → ~/.claude/commands/enhance.md
✓ OpenCode    → ~/.opencode/commands/enhance.md

Ready. In any project, type:

  /enhance build a login page
  /enhance fix the auth bug
  /enhance refactor the user service

Options:

enhance setup --force   # overwrite existing installations
enhance setup --all     # install for all tools even if not detected

Step 3 — Use it

Open Claude Code, OpenCode, or Codex CLI in any project and type:

/enhance build a login page with email and password

---

Usage

Inside Claude Code / OpenCode / Codex CLI (after enhance setup)

/enhance build a login page with email and password
/enhance fix the auth bug
/enhance create a payment form with Stripe
/enhance refactor the user service to use dependency injection
/enhance add dark mode support

Standalone CLI (calls AI directly)

Requires API key:

export ANTHROPIC_API_KEY=sk-ant-...

# Basic — scans project, enhances prompt, calls Claude
enhance "build a login page"

# Dry run — see the enhanced prompt without calling AI
enhance "fix the auth bug" --dry-run

# Show enhanced prompt AND call AI
enhance "create dashboard component" --print-prompt

# See detected stack and intent
enhance "refactor user service" --verbose

# Use a different provider
enhance "add payment form" --provider codex

---

Configuration

Create .enhancerc.json in your project root to customize behavior per-project:

{
  "provider": "claude",
  "model": "claude-sonnet-4-6",
  "maxContextTokens": 3000,
  "customInstructions": "Always use React Query. Prefer named exports."
}

Key	Default	Description
provider	claude	AI provider: claude, codex, opencode
model	claude-sonnet-4-6	Model ID
maxContextTokens	3000	Max characters of project files to include
customInstructions	—	Extra instructions always injected into every prompt

---

Providers

Claude (default)

Requires ANTHROPIC_API_KEY. Get one at console.anthropic.com.

export ANTHROPIC_API_KEY=sk-ant-...
enhance "build login page"

Codex CLI

npm install -g @openai/codex
enhance "build login page" --provider codex

OpenCode

npm install -g opencode
enhance "build login page" --provider opencode

Example Enhancement

Input:

enhance "build login page"

Enhanced prompt sent to AI:

You are working inside a Next.js TypeScript project.

## Project Stack
- Language: TypeScript
- Frameworks: Next.js, React, TailwindCSS, shadcn/ui
- UI Library: shadcn/ui
- ORM: Prisma
- Next.js Router: App Router

## Task
Create: build login page

## Requirements
- Use TypeScript throughout — no `any`, prefer `unknown` with type guards
- Use Server Components by default — only add "use client" when needed
- Follow App Router conventions: page.tsx, layout.tsx, route.ts
- Use `next/navigation` for navigation
- Use Tailwind classes — no custom CSS unless unavoidable
- Use shadcn/ui components over building from scratch
- Never store plain text passwords — use bcrypt or argon2
- Use httpOnly, secure cookies for session tokens — never localStorage
- Validate and sanitize all auth inputs server-side
- Consider rate limiting on login/signup endpoints
- ...
