Frequently Asked Questions about claude-code-headless

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run Claude Code in headless mode for CI/CD pipelines?▼

Headless execution runs Claude Code without a UI using the --print flag and --output-format option (json, text, or stream-json). Use `claude -p "your prompt" --output-format json` to integrate directly into scripts, CI/CD workflows, and automation pipelines for structured, parsing-ready results.

Can I resume and continue multi-turn Claude Code sessions in automation workflows?▼

Yes. Use the -r/--resume and -c/--continue flags to manage session state across multiple invocations. This enables multi-step analyses and complex automation tasks in batch processing without losing context between runs.

What CLI options control permissions and tool access in automated Claude Code execution?▼

Automation supports --allowedTools, --disallowedTools, and permission modes to restrict tool execution in CI/CD and scripting environments. Pair these with --mcp-config to manage Model Context Protocol settings and --verbose for debugging pipeline issues.

How do I integrate Claude Code into shell scripts and batch automation?▼

Use the --print flag with --output-format json to emit structured output that shell scripts and batch processors can parse directly. Combine with -r/--resume for stateful multi-turn workflows and environment-variable integration for credential and configuration management.

Does headless Claude Code support session management for long-running automation tasks?▼

Yes. Session resume (-r) and continuation (-c) flags preserve context and state across separate invocations, enabling checkpoint-based automation, error recovery, and complex multi-step workflows without restarting from scratch.

What output formats does headless Claude Code support for parsing in downstream tools?▼

Headless execution supports three --output-format modes: text for human-readable output, json for programmatic parsing, and stream-json for real-time output streaming in pipelines and monitoring systems.
