Claude CLI Runner

Claude CLI Runner

Use this skill when the user needs to run Claude models from Python code WITHOUT API keys — via the claude CLI binary that uses Claude Code's built-in authentication.

When to Use

• User asks to "run Claude from Python" or "call Claude without API key"
• User needs to process text with Claude in a backend/script
• User wants to integrate Claude into a project that doesn't have API keys configured
• User mentions "claude CLI" or "claude binary"

Module Location

~/.claude/tools/claude_cli.py

Quick Usage

import sys
sys.path.insert(0, "~/.claude/tools")
from claude_cli import claude, claude_async, claude_json, claude_stream, validate_response

# Simple call
result = claude("Fix spelling: Привет мр")

# With system prompt and model
result = claude(
    "Review this code for bugs",
    system="You are a senior developer",
    model="claude-opus-5",
)

# Async
result = await claude_async("Translate to English: ...")

# JSON output
data = claude_json("List 3 colors as JSON array")

# Streaming
for chunk in claude_stream("Write a story"):
    print(chunk, end="")

# Validate LLM response
ok, cleaned = validate_response(original_text, llm_response)
