DiffPilot

AI-powered code review and commit helper for Visual Studio Code.

• Review any commit or staged changes with OpenAI (sends full unified diff, returns a structured Markdown report in Vietnamese).
• Generate Conventional Commit messages (English subject/body) from staged changes.
• One-click model selector in the sidebar footer.
• Enter and store OpenAI API key securely (VS Code SecretStorage, no .env or settings files).
• Fast, repo-native commit list (reads .git via isomorphic-git; diffs via Git CLI).

Highlights

• Review commit: open the sidebar, click Review on any commit → AI report (Tóm tắt, Ảnh hưởng logic cũ, Lỗi nghiêm trọng/khác, Ngoại lệ, Bảo mật, Hiệu năng, Test, Refactor, Rủi ro & Ưu tiên).
• Review staged: analyze your current staged changes before committing.
• Suggest commit: generate a high‑quality Conventional Commit subject/body (English) from staged diffs.
• Footer controls:
  • Model dropdown: choose gpt-4o, gpt-4o-mini, gpt-4.1, or gpt-4.1-mini.
  • Wrench icon: prompt to enter API key (stored in SecretStorage).

Installation

1. Install the extension from the VS Code Marketplace (search “DiffPilot”).
2. Ensure Git is installed and available in your PATH.
3. Open a Git repository folder in VS Code.

Getting Started

1. Open the activity bar item “DiffPilot”.
2. In the footer:
   • Pick your OpenAI model from the dropdown.
   • Click the wrench icon to enter your OpenAI API key (stored securely).
   • Status shows: Model: <name> • API key: đã thiết lập / chưa thiết lập.
3. Use the top toolbar:
   • Refresh: reload commit list.
   • Suggest Commit: create Conventional Commit (from staged).
   • Review Staged: review all staged changes.
4. In the list, click “Review” on any commit to open an AI report.

Permissions & Data Use

• The extension sends only the diffs you explicitly request (commit or staged) to OpenAI for analysis.
• API key is stored in VS Code SecretStorage (encrypted), not in files or environment variables.
• No external telemetry is collected by this extension.

Supported Models

• gpt-4o, gpt-4o-mini
• gpt-4.1, gpt-4.1-mini

Notes:

• “gpt‑5” family is not used here.

Requirements

• Git (to obtain unified diffs)
• OpenAI API key with access to the chosen model
• VS Code ≥ 1.92

Commands

• DiffPilot: Refresh Commits
• DiffPilot: Review Staged Changes
• DiffPilot: Suggest Commit Message from Staged

Known Limitations

• Very large diffs are chunked before sending to the model (the extension merges the responses).
• Private code: ensure your organization’s policy allows sending diffs to OpenAI.

Troubleshooting

• No commits listed:
  • Confirm the folder is a Git repository.
  • On Windows, ensure Git is on PATH for the Extension Development Host.
• “No staged changes”:
  • Stage files first: git add ….
• “Invalid model”:
  • Switch to a listed model in the footer. Unsupported IDs are normalized to gpt-4o-mini.

Privacy

• API key is never written to disk or to extension settings.
• Diffs are transmitted only when you trigger a review or suggestion.
• Review outputs are stored as temporary Markdown documents in your editor.
