Claude Code v2.1.198 landed on July 2, 2026 with what may be its most consequential background-agent update yet: agents you launch with claude agents can now autonomously commit their work, push to a remote, and open a draft pull request when they finish — without waiting for you to return. That changes background agents from an async task-runner into a nearly-hands-off PR generator.

Here is what shipped, what it means for your workflow, and what broke (intentionally) that you need to know about.

Background Agents Now Open Draft PRs Automatically

What changed: When a background agent (claude --bg or launched from claude agents) completes a code task, it now commits its changes, pushes the branch, and opens a GitHub PR flagged as draft — on its own.

What this means: Previously you had to return to the agent session, review the diff, then manually run the commit-push-PR sequence. Now the PR exists by the time you look up. The draft flag means it cannot be merged until you explicitly mark it ready, so the gate is still human-controlled.

Builder checklist:

  • Make sure your agent sessions have Git credentials and GitHub auth in scope. If git push fails silently the agent will still exit “completed” — check the agent log.
  • Draft PRs land in the standard GitHub PR queue. Wire a PR-opened webhook or a CI check if you want notification other than the Jikan-style hook described below.
  • If you do not want auto-commit behavior for a specific task, tell the agent explicitly: “Do not commit when done” in the task prompt. The default is now opt-out, not opt-in.

Notification Hooks: Know When an Agent Needs You

What changed: claude agents now fires two new Notification hooks:

  • agent_needs_input — the session is blocked and waiting for your response
  • agent_completed — the session has finished

What this means: You can wire these hooks in .claude/settings.json to send a system notification, post to Slack, trigger a webhook, or do anything a shell command can do.

Example hook configuration:

{
  "hooks": {
    "Notification": [
      {
        "matcher": "agent_needs_input",
        "hooks": [
          {
            "type": "command",
            "command": "notify-send 'Claude Code' 'Agent needs your input'"
          }
        ]
      },
      {
        "matcher": "agent_completed",
        "hooks": [
          {
            "type": "command",
            "command": "notify-send 'Claude Code' 'Agent finished — check draft PR'"
          }
        ]
      }
    ]
  }
}

On macOS, swap notify-send for osascript -e 'display notification "..." with title "Claude Code"'.

Subagents Now Run in the Background by Default

What changed: Subagents (agents you spawn inside a Claude session, not from the claude agents dashboard) now execute in the background by default. Claude continues working rather than waiting for each subagent to complete sequentially.

What this means: Multi-step tasks where Claude delegates to subagents — code review, test runs, file analysis — now proceed concurrently. Wall-clock time drops for any task that fans out.

Extended thinking and context compaction now inherit the parent session’s configuration. If you run your main session with extended thinking enabled, subagents see that setting too.

Claude in Chrome: Now Generally Available

What changed: The Claude in Chrome browser extension moved from beta to GA. It is stable and supported on all paid plans (Pro, Max, Team, Enterprise).

What it does: The extension runs as a side panel and gives Claude direct access to the active tab — it can read page content, click elements, fill forms, navigate, and extract data. It uses the Agent SDK and connects to the same session as your Claude Code session when active together.

Builder use cases that are now stable (not beta-risk):

  • Automating web-based dashboards that have no API (scrape → process → export)
  • End-to-end testing workflows that need a real browser context
  • Filling enterprise portals that block headless browsers
  • Cross-tab data aggregation (Claude can read multiple open tabs)

Note on trust: The extension operates at the browser-agent level, meaning it acts with your logged-in credentials on every site. Treat any prompt that asks you to install Claude for Chrome from a source other than the Chrome Web Store as a phishing attempt.

/dataviz Skill: Built-in Chart Design Guidance

What changed: A new /dataviz skill is available in the skill library. It provides chart and dashboard design guidance and ships with a runnable color-palette validator.

What this means for you: Rather than describing your chart layout in prose and iterating, you can invoke /dataviz to get opinionated guidance on chart type selection, axis labeling, color accessibility, and layout hierarchy. The color-palette validator outputs whether a palette passes WCAG contrast thresholds for common chart background scenarios.

Quick usage:

/dataviz

Then describe your data: what dimensions, what audience, what decision the chart supports. The skill returns a recommended chart type, color recommendations, and a validator you can run against your hex codes.

Explore Agent Now Inherits Your Session Model

What changed: The built-in Explore agent previously always ran on Haiku regardless of your session model. Now it inherits the main session model, capped at Opus.

What this means: If you are on Sonnet 5 or Fable 5, Explore queries now run on that model rather than the cheapest available. You get better codebase reasoning on large repos. The Opus cap prevents runaway costs if you are in an Opus session and fire off many Explore queries.

AWS Platform Support in Gateway

What changed: Claude Platform on AWS (anthropicAws) is now a recognized upstream provider in Gateway.

What this means: Teams running Claude via Amazon Bedrock can now route through Claude Code’s Gateway layer with the same configuration pattern as direct Anthropic API access. Gateway benefits — request logging, rate-limit pooling, credential abstraction — apply to Bedrock-hosted Claude without custom integration.

Reliability Fixes Worth Knowing About

Background tasks stuck on “Running”: A bug caused background tasks to show “Running” indefinitely after they completed or after you resumed a session. Fixed. If you were building tooling that polled task status, this was a false-positive source.

52-second reconnect loop on macOS fixed: Background agents were dropping and attempting reconnection every ~52 seconds on macOS, producing log noise and brief interruptions. This is now resolved.

Agent team failure visibility: Previously, a teammate agent that crashed on an API error would simply disappear from the team view. It now reports a “failed” status to the lead agent, which can decide whether to retry or escalate.

AWS STS token expiry: Sessions using AWS credentials with short-lived STS tokens now auto-run awsAuthRefresh when the token expires, rather than erroring out mid-session.

Plan mode auto-allows read-only tool calls: In plan mode, Claude previously prompted for permission on every tool call including read-only operations like file reads and searches. Now read-only calls are auto-allowed, which eliminates the most repetitive approval prompt in plan-mode sessions.

.claude/rules/ via symlinks: Conditional rules defined in .claude/rules/ were silently ignored when the directory was accessed through a symlink. Fixed.

claude attach <id> exit behavior: Previously, claude attach <id> would attach and then immediately exit back to shell. Fixed — it now opens the agent view as expected.

Breaking Change: /agents Wizard Removed

What changed: The /agents wizard, a guided flow for setting up agent configurations, has been removed.

Migration: You now have two paths:

  1. Ask Claude directly: describe the agent you want to create and Claude will scaffold the configuration.
  2. Edit .claude/agents/ directly: agent configs are YAML files in that directory; the schema is documented at code.claude.com/docs.

The wizard was removed because direct-editing and natural-language scaffolding cover the same ground without a separate menu surface.

Upgrade

npm install -g @anthropic-ai/claude-code@latest
claude --version   # expect 2.1.198

Or if you use the desktop app, it auto-updates.

Summary

The headline is background agents: they now complete the loop — commit, push, PR — without waiting for you. Paired with the agent_completed hook, you can build a nearly-hands-free parallel dev workflow where agents work, submit PRs, and page you only when blocked. Chrome GA removes the beta asterisk for browser-automation use cases. The /dataviz skill and Explore model inheritance are practical quality-of-life additions. And the reliability fixes — especially the 52-second reconnect loop and plan-mode read-only approvals — remove friction from the workflows that were grinding daily users.
