Claude Shortcuts !

#

🚀 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]
