DeepSeek Commit

A deliberately tiny VS Code extension that writes Git commit messages with DeepSeek's chat completions API.

I made this because i heavily use https://github.com/lhr0909/deepseek-fim-autocomplete-vscode-extension by Simon Liang

Features

• Sparkle button in the Source Control view toolbar that asks DeepSeek for a Conventional Commits message.
• A button inside the commit message box is not possible: VS Code only exposes that spot through the proposed contribSourceControlInputBoxMenu API, which cannot be used by a published extension.
• Uses the staged diff, and falls back to the working tree diff (with the list of untracked files) when nothing is staged.
• Never overwrites a commit message you already typed.
• Simple JSON settings for API key, model, base URL, timeout, diff size and extra instructions.
• Unit tests for the core request/config/message logic.

Settings

Add these to your VS Code settings.json:

{
  "deepseekCommit.apiKey": "YOUR_DEEPSEEK_API_KEY",
  "deepseekCommit.model": "deepseek-v4-flash",
  "deepseekCommit.baseUrl": "https://api.deepseek.com/beta",
  "deepseekCommit.commitMessage.instructions": "Be concise and precise."
}

deepseekCommit.commitMessage.maxDiffChars (default 12000) truncates large diffs before they are sent, and deepseekCommit.commitMessage.maxTokens (default 1000) caps the generated message.

Temperature is not configurable: DeepSeek's thinking models ignore it. The extension sends thinking: { type: "disabled" } so reasoning tokens cannot eat the message budget.

Generate a commit message

Stage your changes (unstaged changes are used when nothing is staged), then click the sparkle icon in the Source Control view title bar, or run DeepSeek Commit: Generate Commit Message from the Command Palette. The message is written to the commit message box only if it is empty.

No keybinding is assigned by default; bind deepseekCommit.generateCommitMessage yourself if you want one.
