Headless Mode enables Claude Code to run autonomously in CI/CD pipelines, cron jobs, and background processes without a terminal UI. This unlocks powerful automation patterns:
Claude Code can spawn specialized subagents for parallel tasks. For example, when refactoring a large codebase, the primary agent might spawn subagents to handle different modules simultaneously — one for the API layer, one for the frontend, and one for test updates. Each subagent operates in its own context but reports results back to the orchestrator.
| Command | Purpose |
|---|---|
/loop | Autonomous iteration until a condition is met |
/btw | Side-query without polluting the main conversation context |
/insights | Analyze workflow friction and suggest optimizations |
/plan | Force the agent to output a plan before any modifications |
Claude Code sessions can survive disconnections. If your SSH session drops or your laptop sleeps, the agent continues working. Remote control features allow you to reconnect and monitor progress from any device, including mobile.
