Claude Code

Claude Code

Delegate coding tasks to Claude Code via the Hermes terminal. Claude Code is Anthropic's autonomous coding agent CLI.

Prerequisites

• Claude Code installed: npm install -g @anthropic-ai/claude-code
• Authenticated: run claude once to log in
• Use pty=true in terminal calls — Claude Code is an interactive terminal app

One-Shot Tasks

terminal(command="claude 'Add error handling to the API calls'", workdir="/path/to/project", pty=true)

For quick scratch work:

terminal(command="cd $(mktemp -d) && git init && claude 'Build a REST API for todos'", pty=true)

Background Mode (Long Tasks)

For tasks that take minutes, use background mode so you can monitor progress:

# Start in background with PTY
terminal(command="claude 'Refactor the auth module to use JWT'", workdir="~/project", background=true, pty=true)
# Returns session_id

# Monitor progress
process(action="poll", session_id="<id>")
process(action="log", session_id="<id>")

# Send input if Claude asks a question
process(action="submit", session_id="<id>", data="yes")

# Kill if needed
process(action="kill", session_id="<id>")

PR Reviews

Clone to a temp directory to avoid modifying the working tree:

terminal(command="REVIEW=$(mktemp -d) && git clone https://github.com/user/repo.git $REVIEW && cd $REVIEW && gh pr checkout 42 && claude 'Review this PR against main. Check for bugs, security issues, and style.'", pty=true)

Or use git worktrees:

terminal(command="git worktree add /tmp/pr-42 pr-42-branch", workdir="~/project")
terminal(command="claude 'Review the changes in this branch vs main'", workdir="/tmp/pr-42", pty=true)

Parallel Work

Spawn multiple Claude Code instances for independent tasks:

terminal(command="claude 'Fix the login bug'", workdir="/tmp/issue-1", background=true, pty=true)
terminal(command="claude 'Add unit tests for auth'", workdir="/tmp/issue-2", background=true, pty=true)

# Monitor all
process(action="list")

Key Flags

Rules

1. Always use pty=true — Claude Code is an interactive terminal app and will hang without a PTY
2. Use workdir — keep the agent focused on the right directory
3. Background for long tasks — use background=true and monitor with process tool
4. Don't interfere — monitor with poll/log, don't kill sessions because they're slow
5. Report results — after completion, check what changed and summarize for the user
