If you’ve used Claude Code’s background agents before v2.1.198, you know the rhythm: kick off a task in the Agent View, let it run in the background, and then check back periodically to see if it’s waiting for you to review changes or commit them. Starting with v2.1.198, that last step is gone. Background agents now automatically commit their work, push it to a branch, and open a draft pull request when a coding task completes — no prompt, no hand-holding, no manual step required.

This guide walks you through what changed, how the feature works in practice, and how to pair it with the new notification hooks so you get an alert the moment your agent is done.

What Changed in v2.1.198

When a background agent launched from claude agents finishes code work in a Git worktree, it now:

  1. Commits all staged changes with an auto-generated commit message
  2. Pushes the branch to the remote repository
  3. Opens a draft pull request for human review

This happens automatically, without any AskUserQuestion dialog or manual confirmation. A few safeguards are built in:

  • The auto-commit behavior skips main and master branches — your primary branches are protected
  • No force-pushes are ever performed
  • If you have settings that disable PR creation, those are respected

Before this update, agents would complete their work in the worktree and then stop, waiting for you to run git commit and open a PR yourself. Now the loop closes automatically.

Prerequisites

  • Claude Code v2.1.198 or later (run claude --version to check)
  • A Git repository with a configured remote (GitHub, GitLab, etc.)
  • Active Claude Code session with the Agent View open (claude agents)

How Worktrees and the Draft PR Flow Work

Claude Code uses Git worktrees to isolate background agent work from your main working directory. When you launch a background agent, it gets its own worktree — a separate checkout of your repo — so it can make changes without touching your current branch.

When the agent finishes:

  1. Changes are committed inside the worktree
  2. The worktree branch is pushed to your remote
  3. A draft PR is opened pointing from that branch back to your target branch

You’ll see the PR appear in your repository’s pull request list. Because it’s a draft, it signals to reviewers (and CI pipelines, depending on your setup) that this is work-in-progress awaiting review.

Setting Up Notification Hooks for Agent Completion

By default, you won’t get a desktop or terminal notification when a background agent finishes — you’d need to check the Agent View manually. Two new hook events in v2.1.198 solve this:

  • agent_completed — fires when a session finishes (successfully or with an error)
  • agent_needs_input — fires when a session is waiting for user input

You can wire these to any shell command using the Notification hook type in your Claude Code settings file (~/.claude/settings.json):

{
  "hooks": {
    "Notification": [
      {
        "matcher": "",
        "hooks": [
          {
            "type": "command",
            "command": "# Replace with your preferred notification command"
          }
        ]
      }
    ]
  }
}

For macOS, a common notification command uses osascript:

osascript -e 'display notification "Claude Code agent finished" with title "Claude Code"'

For Linux, you might use notify-send:

notify-send "Claude Code" "Background agent completed"

Important: The exact matcher syntax and available event fields are documented in the official Claude Code Hooks reference. The snippet above gives you the general shape; refer to the official docs for the full event schema, how to distinguish agent_completed from agent_needs_input, and how to include context like the session ID or task description in your notification message.

Note: Notification hooks only fire while the Agent View is open. If you close Claude Code entirely, hooks won’t run until the view is open again.

Practical Workflow Example

Here’s a typical agentic coding session with v2.1.198:

  1. Open Claude Code: claude agents
  2. Launch a background agent with a coding task (e.g., “Refactor the authentication module to use the new token format”)
  3. Continue working on other tasks — the agent runs in its worktree
  4. Your notification hook fires when the agent completes
  5. Navigate to your repository’s pull requests page — you’ll find a new draft PR waiting for your review
  6. Review the diff, run your CI checks, and either approve/merge or leave comments for the agent to address

The draft PR state ensures your repo’s CI and review policies aren’t inadvertently triggered before you’ve had a chance to look at the work.

What This Doesn’t Do

To manage expectations:

  • No automated testing: The agent commits and opens the PR, but running test suites after the commit is outside this feature’s scope. You can set up CI to trigger on draft PRs if your provider supports it, but that’s a CI configuration task.
  • No conflict resolution: If the worktree branch falls out of sync with your target branch, you’ll need to handle the merge conflict manually.
  • Main/master branches are excluded: You can’t accidentally auto-commit directly to your primary branch. The agent will always work in its own isolated branch.

Summary

Claude Code v2.1.198 closes the loop on background agent workflows by automating the final commit-push-PR step. Combined with the new agent_completed and agent_needs_input notification hooks, you can now run multi-hour background coding tasks and get notified the moment something needs your attention — without ever having to poll the Agent View or check GitHub manually.

Check your Claude Code version with claude --version and update if you’re not on 2.1.198 or later. Then open a worktree session and let the agents work.
