Claude Shortcuts !

An engineer compiled a cheat sheet of Claude Code CLI flags, covering automation, permissions, cost control, workspace management, session handling, and prompt customization. The flags enable non-interactive scripting, strict output validation, tool permissions, financial circuit breakers, and session forking.

🚀 Automation & Scripting - -p / --print: Non-interactive mode. Runs a query, outputs the result to stdout, and terminates immediately essential for CI/CD . - --output-format : Formats Claude's responses, enabling structured JSON parsing using tools like jq. - --json-schema : Strict output validation. Compels Claude to respond using a specific, predefined JSON structure only works with -p . - --bare: Minimal start mode. Bypasses MCP servers, plugins, hooks, and CLAUDE.md to optimize launch times for scripting tasks. 4, 5, 6, 7, 8 🔒 Permissions & Security - --permission-mode : Sets the target initial session layer default, plan, acceptEdits, bypassPermissions . - --allowedTools / --allowed-tools: Declares specific tools like Read or Bash that Claude can run automatically without prompting for manual approval. - --disallowedTools: Completely strips specified tools out of Claude's runtime environment. - --dangerously-skip-permissions: Completely turns off all confirmation prompts for tool executions. 4, 5, 9, 10 ⏱️ Cost Control & Safety Caps - --max-turns : Defines an upper ceiling for multi-step agentic execution loops to prevent runaway token spend. - --max-budget-usd : Sets a strict financial circuit breaker by capping the session's overall API dollar cost. 3, 5, 6, 11 📁 Workspace & Context - --add-dir : Integrates secondary directories into Claude’s execution space so it can read and update external code. - -w / --worktree: Instructs Claude to open and execute inside an isolated git worktree, keeping your main branch clean. 4, 6, 9, 12 💬 Session Management - -c / --continue: Picks up right where you left off in the directory's most recent conversation thread. - -r / --resume : Re-opens an exact target historic thread using its specific Session UUID or name. - --fork-session: Branches an active historical context into a fresh, distinct session ID without altering your past logs. 5, 7, 13 📝 Prompt Customization - --system-prompt : Fully replaces Claude Code's stock system rules with your own string. - --append-system-prompt : Appends specialized custom formatting or architecture constraints seamlessly onto the existing system instructions. 5, 7 1 https://x.com https://x.com/ avichawla/status/2073327425711460834 2 https://shipyard.build https://shipyard.build/blog/claude-code-cheat-sheet/ 3 https://www.linkedin.com https://www.linkedin.com/posts/vamsipenmetsa claude-code-has-20-cli-flags-most-engineers-activity-7477298683571728384-Albo 4 https://code.claude.com https://code.claude.com/docs/en/cli-reference 5 https://github.com https://github.com/shanraisshan/claude-code-best-practice/blob/main/best-practice/claude-cli-startup-flags.md 6 https://www.gravitee.io https://www.gravitee.io/blog/claude-code-cli-documentation-commands-flags-and-governance 7 https://www.mager.co https://www.mager.co/blog/2026-04-20-claude-code-cli-flags/ 8 https://codingnomads.com https://codingnomads.com/claude-code-cli-commands-flags-reference 9 https://phosailabs.com https://phosailabs.com/blog/claude-code-cli-commands-guide 10 https://www.gravitee.io https://www.gravitee.io/blog/claude-code-cli-documentation-commands-flags-and-governance 11 https://codingnomads.com https://codingnomads.com/claude-code-cli-commands-flags-reference 12 https://timdietrich.me https://timdietrich.me/blog/claude-code-commands-guide/ 13 https://github.com https://github.com/shanraisshan/claude-code-best-practice/blob/main/best-practice/claude-cli-startup-flags.md
