Claude Code

Claude Code Skill

Interact with Claude Code (Anthropic's CLI) running in a persistent tmux session.

Prerequisites

The Claude Code tmux session must be running:

systemctl --user start claude-tmux

Or manually:

~/.local/bin/claude-tmux-start.sh

Sending Prompts

Use the helper script to send a prompt and capture the response:

{baseDir}/scripts/ask-claude.sh "Your prompt here"

Or manually via tmux:

# Send prompt
tmux send-keys -t claude 'Your prompt here' Enter

# Wait for response (check for prompt symbol)
sleep 10

# Capture output
tmux capture-pane -t claude -p -S -100

Checking Status

{baseDir}/scripts/claude-status.sh

Returns:

• running - Claude Code is ready for prompts
• busy - Claude is processing a request
• stopped - Session not running

Session Management

# Start session
systemctl --user start claude-tmux

# Stop session
systemctl --user stop claude-tmux

# Restart session
systemctl --user restart claude-tmux

# Attach to session (interactive)
tmux attach -t claude
# Detach with Ctrl+B, then D

Output Parsing

Claude Code output includes:

• ❯ - Input prompt (ready for new input)
• ● - Claude's response text
• ⏵⏵ - Status line (bypass permissions indicator)

To extract just the response:

{baseDir}/scripts/ask-claude.sh "prompt" | grep "^●" | sed 's/^● //'

Example Usage

# Simple question
{baseDir}/scripts/ask-claude.sh "What is 2+2?"

# Code generation
{baseDir}/scripts/ask-claude.sh "Write a Python function to reverse a string"

# File operations (Claude has access to filesystem)
{baseDir}/scripts/ask-claude.sh "Read and summarize ~/notes.txt"

Tips

• Keep prompts concise for faster responses
• Claude Code has full filesystem access in bypass permissions mode
• For long operations, increase the wait timeout
• Check ~/.local/share/claude-tmux.log for session logs
