feat(mcp): route Playwright MCP through Patchright by default

Summary

• Make Patchright the default undetectable backend for any Playwright MCP usage launched via dotfiles.
• Non-invasive: implemented as shim + wrapper; no app code changes.

Changes

• Add Patchright shim that intercepts require('playwright') → Patchright.
• Add wrapper script and point Playwright MCP to it in configs:
  • mcp/mcp.json, .mcp.json
  • .codex/config.toml
• Default enabled; provide simple opt-out flag.

Usage

• Default: Patchright enabled.
• Opt-out: set USE_PATCHRIGHT=0 (or false) to use vanilla Playwright.
• Optional debug: USE_PATCHRIGHT_DEBUG=1 prints shim activation to stderr.

Dependencies (not auto-installed)

• Install Patchright in shim dir and Chromium once:
  • cd mcp/patchright-shim && npm init -y && npm i patchright
  • npx patchright install chromium
• Playwright MCP can run via npx (current config) or be installed locally if desired.

Verification

• List MCP tools to confirm server runs via wrapper.
• Navigate to about:blank and screenshot using mcp__playwright__* tools.

Notes

• No references to private apps; this is general dotfiles MCP wiring.
• Flag-driven approach keeps behavior reversible and minimal.

Using Amazon Q Developer for GitHub

Amazon Q Developer¹ is an AI-powered assistant that integrates directly into your GitHub workflow, enhancing your development process with intelligent features for code development, review, and transformation.

Slash Commands

Command	Description
/q <message>	Chat with the agent to ask questions or request revisions
/q review	Requests an Amazon Q powered code review
/q help	Displays usage information

Features

Agentic Chat
Enables interactive conversation with Amazon Q to ask questions about the pull request or request specific revisions. Use /q <message> in comment threads or the review body to engage with the agent directly.

Code Review
Analyzes pull requests for code quality, potential issues, and security concerns. Provides feedback and suggested fixes. Automatically triggered on new or reopened PRs (can be disabled for AWS registered installations), or manually with /q review slash command in a comment.

Customization

You can create project-specific rules for Amazon Q Developer to follow:

1. Create a .amazonq/rules folder in your project root.
2. Add Markdown files in this folder to define rules (e.g., cdk-rules.md).
3. Write detailed prompts in these files, such as coding standards or best practices.
4. Amazon Q Developer will automatically use these rules when generating code or providing assistance.

Example rule:

All Amazon S3 buckets must have encryption enabled, enforce SSL, and block public access.
All Amazon DynamoDB Streams tables must have encryption enabled.
All Amazon SNS topics must have encryption enabled and enforce SSL.
All Amazon SNS queues must enforce SSL.

Addressed portability: removed hardcoded absolute paths.\n\n- Wrapper now resolves its own directory and sets NODE_PATH dynamically\n- MCP configs call 'patchright-playwright-mcp' from PATH (no absolute paths)\n- setup-all-mcp-servers.sh creates ~/.local/bin symlink to the wrapper\n\nThis keeps the repo portable across machines/worktrees without referencing private directories.
