AI Commit

Generate commit messages using any AI coding assistant you already have installed. No API keys needed — uses your existing CLI authentication.

Features

Agent-agnostic — works with Claude Code, Gemini CLI, OpenAI Codex, GitHub Copilot, Cursor, or any custom CLI
Zero configuration — auto-detects the first available AI CLI on your system
SCM integrated — sparkle button in the Source Control title bar, right where you commit
Smart diff handling — truncates large diffs at file boundaries to stay within token limits
Customizable prompts — configure the prompt template and add extra instructions
Clean output — strips markdown fences, preamble text, and explanations from AI responses

Setting	Default	Description
`aiCommit.provider`	`auto`	Which AI to use (`auto`, `claude`, `gemini`, `codex`, `copilot`, `cursor`, `custom`)
`aiCommit.custom.command`	—	Custom CLI command. Use `{prompt}` placeholder
`aiCommit.promptTemplate`	Conventional commits	Prompt template. Use `{diff}` placeholder
`aiCommit.extraInstructions`	—	Additional instructions appended to the prompt
`aiCommit.maxDiffLength`	`20000`	Max diff chars before truncation
`aiCommit.timeout`	`60`	CLI timeout in seconds
`aiCommit.verbosity`	`2`	Commit message detail level (1–5)
`aiCommit.claude.extraArgs`	`[]`	Extra Claude CLI args (e.g., `["--model", "claude-sonnet-4-6"]`). Empty = CLI default
`aiCommit.gemini.extraArgs`	`[]`	Extra Gemini CLI args (e.g., `["--model", "gemini-2.5-flash"]`)
`aiCommit.codex.extraArgs`	`[]`	Extra Codex CLI args (e.g., `["--model", "gpt-5"]`)
`aiCommit.copilot.extraArgs`	`[]`	Extra Copilot CLI args
`aiCommit.cursor.extraArgs`	`[]`	Extra Cursor CLI args

aiCommit.verbosity controls commit message detail:

Level	Output
1	Subject only (≤50 chars) — default
2	Subject + 1 short body line
3	Subject + 2-3 bullets (what & why)
4	Subject + grouped bullet body (detailed)
5	Full commit: subject + motivation, changes, rationale, impact

Set in settings:

{ "aiCommit.verbosity": 3 }

By default, each CLI uses its own default model. To override, set extraArgs with the model flag for that CLI. Examples:

{
  "aiCommit.claude.extraArgs": ["--model", "claude-haiku-4-5"],
  "aiCommit.gemini.extraArgs": ["--model", "gemini-2.5-flash"]
}

Check each CLI's --help for supported flags and model names.

To use any CLI tool that accepts a prompt and outputs text:

{
  "aiCommit.provider": "custom",
  "aiCommit.custom.command": "my-ai generate \"{prompt}\""
}
