Claude Code CLI (Anthropic)
Agentic coding tool by Anthropic. Reads, edits, and runs code with full project context. Supports non-interactive print mode for programmatic use.
Detect Installation
bashwhich claude # should return a path claude --version
Install
bashnpm install -g @anthropic-ai/claude-code
Requires authentication: run claude auth login (Anthropic account or --console for API billing).
Non-Interactive Usage (print mode)
For programmatic invocation from Research-Claw, use -p (print mode):
bash# Basic non-interactive execution claude -p "Refactor the auth module to use async/await" # Pipe content for analysis cat src/utils.ts | claude -p "Find bugs in this file" # JSON output for parsing claude -p --output-format json "List all TODO comments in the project" # Skip permission prompts (for fully automated pipelines) claude -p --dangerously-skip-permissions "Fix all lint errors" # Budget and turn limits claude -p --max-turns 5 --max-budget-usd 2.00 "Add unit tests for the auth module" # Model selection claude -p --model sonnet "Explain this codebase architecture"

Research-Claw exec Patterns
bash# Delegate a complex coding task exec("claude -p --dangerously-skip-permissions --max-turns 10 'Implement the feature described in TODO.md'") # Read-only analysis with budget cap exec("claude -p --tools 'Read' --max-budget-usd 1.00 'Review code quality and list issues'") # JSON output for structured results exec("claude -p --output-format json 'List all exported functions in src/'")
