PromptShift ⚡ Universal AI Coding Agent Transpiler & Drift Guard

Deterministic AST transpilation and secret sanitation between Cursor (.mdc), Claude Code (CLAUDE.md), Windsurf (.windsurfrules), GitHub Copilot, Cline, and Roo Code.

The Problem: AI Rule Fragmentation & Multi-IDE Drift

Modern engineering teams often collaborate across multiple AI-assisted developer environments:

• Cursor uses granular frontmatter-annotated markdown rules (.cursor/rules/*.mdc) and .cursorrules.

• Claude Code expects a unified root instruction context (CLAUDE.md).

• Windsurf relies on .windsurfrules.

• GitHub Copilot looks for .github/copilot-instructions.md.

• Aider, Cline & Roo Code each define custom agent boundaries.

When an engineer updates CLAUDE.md but forgets to synchronize .cursor/rules/, AI coding agents develop conflicting behaviors, hallucinate mismatched constraints, and accidentally commit sensitive API keys.

PromptShift eliminates fragmentation with certified 98.5% AST semantic parity, OWASP In-RAM secret sanitization, and instant CI/CD drift guards.

⚡ Quick Start

1. One-Command Continuous CI/CD Guard

Bootstrap automated PR parity verification and secret scanning in 2 seconds:

npx promptshift --init-ci

2. Zero-Install CLI (NPX)

Transpile rules locally without permanent installation:

# Real-time watcher: automatically syncs rules across Cursor & Claude on every Ctrl+S (0.02s)
npx promptshift --watch

# Audit workspace for rules drift and exposed secrets
npx promptshift --check

# Transpile from current project to Claude Code
npx promptshift --to=claude

# Transpile from current project to GitHub Copilot
npx promptshift --to=copilot

# Transpile from current project to Windsurf
npx promptshift --to=windsurf

# Get official certified badge for your README.md
npx promptshift --badge

2. Model Context Protocol (MCP) Integration

PromptShift includes a native STDIO JSON-RPC 2.0 MCP server compatible with Claude Desktop, Cursor, Glama.ai, and Smithery.ai.

Claude Desktop Configuration (claude_desktop_config.json)

{
  "mcpServers": {
    "promptshift": {
      "command": "npx",
      "args": ["-y", "promptshift", "--mcp"]
    }
  }
}

Docker Container Execution (Glama Firecracker & Local MicroVMs)

# Build and run the lightweight MCP server via Docker
docker build -t promptshift .
docker run -i --rm promptshift

Exposed MCP Tools (TDQS 5-Star Grade A):

• promptshift_transpile: Deterministically compiles rules between Cursor, Claude Code, Windsurf, Copilot, Cline, and Aider with 98.5% AST parity.

• promptshift_sanitize_secrets: Automatically redacts exposed OpenAI, Anthropic, AWS, GitHub, and Stripe API keys in-RAM before commits.

• promptshift_validate_ast: Measures semantic AST fidelity and prompt drift percentage between source and target instruction documents.

🔄 GitHub Actions CI/CD Drift Guard

Add PromptShift to your pull request workflows to automatically enforce rule synchronization across your team:

# .github/workflows/ai-rules-sync.yml
name: AI Agent Rules Synchronization & Drift Guard

on:
  pull_request:
    paths:
      - 'CLAUDE.md'
      - '.cursor/rules/**'
      - '.windsurfrules'

jobs:

    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Run PromptShift AST Sync
        uses: topaisaas-dev/promptshift@v1.1.0

🔒 Security & OWASP Secret Sanitizer

All transpilation processes run 100% in-memory with zero disk persistence and zero telemetry. Before converting instructions, PromptShift runs an OWASP heuristic regex scanner to sanitize:

• OpenAI API Keys (sk-proj-...)

• Anthropic API Keys (sk-ant-...)

• GitHub Tokens (ghp_..., github_pat_...)

• AWS Access Keys (AKIA...)

• Stripe API Keys (sk_live_..., rk_live_...)

• Private RSA / OpenSSH Cryptographic Headers

Leaked credentials are substituted in-place with [REDACTED_API_KEY].
