I recently was editing a few different web applications and mistakenly ran an update that affected the wrong site and all my sidebar navigation was gone. This was not evident for a few days when I went to update my music practice app and all navigation had disappeared. I had not been reliably committing to get so I looked into how to Auto commit to git so that this would not happen again.

I started with a Background plugin approach and while this would save myself from trouble I had caused, the commit messages were only time stamped.

BackGround Plugin Method

Make the plugins directory either in the project root or in the ~/.config/opencode/plugins.

mkdir -p .opencode/plugins

import type { Plugin } from "@opencode-ai/plugin"

export const AutoCommitPlugin: Plugin = async ({ $ }) => {
  return {
    event: async ({ event }) => {
      // Fires when the agent finishes processing a prompt
      if (event.type === "session.idle") {
        try {
          // Check if there are any modified or untracked files
          const status = await $`git status --porcelain`.text()
          if (!status.trim()) return

          // Stage all changes and commit with a timestamp
          await $`git add -A`
          const timestamp = new Date().toISOString().replace("T", " ").slice(0, 19)
          await $`git commit -m "opencode: auto-commit (${timestamp})"`
        } catch (err) {
          // Silently ignore if not in a git repo or nothing to commit
        }
      }
    },
  }
}

Verification: Start opencode in your project directory, ask it to make a small edit (e.g., adding a comment to a file), and once it finishes, run git log -n 1 in a separate terminal to confirm the new commit appears.
