Deprecation Checker

Overview

The Deprecation Checker is a specialized AI agent designed to act as an expert code reviewer focused exclusively on identifying outdated or deprecated usage within your codebase changes. When you are nearing completion of a feature or submitting a Pull Request (PR), this tool ensures that the code adheres to current best practices by flagging any APIs, methods, libraries, or syntax patterns marked as obsolete.

Capabilities

• Targeted Scanning: Focuses analysis specifically on files modified within the current branch or PR context, saving time over full codebase scans.
• Identification: Accurately pinpoints instances of deprecated code usage across various languages and frameworks.
• Contextual Explanation: Provides clear reasoning for why a pattern is deprecated (e.g., security risks, performance improvements, maintenance overhead).
• Modernization Guidance: Offers specific, actionable replacement suggestions with examples to guide the developer toward current best practices.

Example Use Cases

1. Pre-Submission Review: After implementing a new feature using older APIs, run this agent against your local branch changes to get a comprehensive list of necessary updates before merging.
2. PR Quality Gate: Before approving a PR, use the agent to verify that no deprecated patterns have been accidentally introduced by contributors.
3. Code Refactoring: When updating an old module, feed the relevant files into this agent to receive a prioritized roadmap of required modernizations.
