chub-guard-init 1.2.1

One-command setup for chub_guard - the AI SDK deprecation linter

🛡️ chub-guard-init (v1.2.1)

The Universal Deprecation Guard for modern engineering teams.

📖 The Problem

Modern development moves fast. AI coding assistants often suggest deprecated APIs, and browser automation tools (Selenium, Playwright) change their signatures frequently. Standard linters miss these semantic deprecations, leading to production bugs and technical debt.

🚀 The Solution

chub-guard-init is the official one-command setup for chub-guard. It installs a specialized git-hook that blocks deprecated patterns—from AI SDKs and Automation to Legacy Python—before they ever reach your codebase by syncing with live documentation.

🏎️ Usage

Option 1: pipx (Recommended)

Run this command once at the root of any project:

pipx run chub-guard-init

Option 2: Standard pip

pip install chub-guard-init
chub-guard-init

Run on demand (Universal Scan)

Run a full project scan at any time to generate a detailed report:

chub-guard-init run-all

This generates a chub_guard_report.md with recommended fixes, trend lines, and Agent-ready prompts.

✨ Key Features

1. Hybrid Analysis (Resilient Engine)

Unlike standard linters that fail on syntax errors, chub-guard uses a Resilient Regex Engine. It will still detect critical automation and SDK deprecations even in files with Python 2/3 conflicts or broken refactors.

2. Polyglot Support

A single tool to guard your entire polyglot stack:

• 🐍 Python: Advanced AST analysis for context managers and keyword arguments.
• 🟨 JavaScript/TypeScript: Support for import, require, and React/Angular scoping.
• ☕ Java: Package-level import detection.
• ⚙️ C/C++: Header-based deprecation matching.

3. Rich Markdown Reporting

Generates a chub_guard_report.md featuring:

• 📈 Trend Tracking: See if your technical debt is increasing or decreasing over time.
• 🤖 Agent-Ready Prompts: Copy-paste prompts designed to let your AI Assistant (Cursor/Gemini) fix all issues in one go.
• 💡 Embedded Fixes: Exact code blocks for modern replacements, extracted directly from official docs.

4. Community-Powered Intelligence

• Live Docs: Fetches the latest migration guides from Andrew Ng's context-hub.
• Global Sync: Automatically stays updated with the latest community-contributed patterns from GitHub.

---

🧠 What does it guard?

• 🤖 AI SDKs: Catches breaking changes in OpenAI, Gemini, Anthropic, Langchain.
• 🌐 Browser Automation: Detects deprecated Selenium (find_element_by_id) and Playwright patterns.
• 🐍 Legacy Code: Identifies Python 2 syntax and legacy urllib2/xrange.
• 🏗️ Framework Smells: Detects architectural misconfigurations (e.g. React/Angular mixing).
• ✨ Dynamic Docs: Automatically flags any pattern marked as "deprecated" in official documentation fetched via Context-Hub.

---

🏁 After Setup

Every time you git commit, the guard will scan your changed files. If it finds a deprecated pattern, it will block the commit and provide a rich terminal guide extracted directly from official docs.

---

⚙️ Configuration

Suppressing False Positives

Append # noqa: CHUB to any line:

import google.generativeai as genai  # noqa: CHUB

Syncing with the Ecosystem
