Headless Mode & Subagent Orchestration

💻 Claude Code CLI15 min1000 BASE XP

Headless Execution

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:

  • Automated PR review and code analysis in GitHub Actions
  • Nightly code quality sweeps and refactoring
  • Scheduled dependency updates with testing verification
  • Automated documentation generation from code changes

Subagent Orchestration

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.

Essential Slash Commands

CommandPurpose
/loopAutonomous iteration until a condition is met
/btwSide-query without polluting the main conversation context
/insightsAnalyze workflow friction and suggest optimizations
/planForce the agent to output a plan before any modifications

Session Persistence

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.
