Crawler Summary

claude-code-callback answer-first brief

Asynchronous code development using Claude Code CLI with Hook-based callbacks. Use when the user requests complex programming tasks, code generation, refactoring, or multi-file development work. Dispatches tasks to Claude Code in the background using nohup, then receives completion notifications via Stop/SessionEnd hooks that trigger a Wake Event back to OpenClaw. Zero-polling design saves tokens. Requires: Claude Code CLI (`claude`) installed on the host. --- name: claude-code-callback description: > Asynchronous code development using Claude Code CLI with Hook-based callbacks.

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

name: claude-code-callback description: > Asynchronous code development using Claude Code CLI with Hook-based callbacks. Use when the user requests complex programming tasks, code generation, refactoring, or multi-file development work. Dispatches tasks to Claude Code in the background using nohup, then receives completion notifications via Stop/SessionEnd hooks that trigger a Wake Event back to OpenClaw. Zero-polling design saves tokens. Requires: Claude Code CLI (`claude`) installed on the host.

Claude Code Callback Skill

Dispatch development tasks to Claude Code asynchronously and receive results via Hook callbacks.

Architecture

User Request → OpenClaw dispatches task (nohup) → Claude Code runs independently
    ↓                                                      ↓
OpenClaw is free                              Stop/SessionEnd Hook fires
(handles other tasks)                                      ↓
    ↓                                         notify-openclaw.sh runs
    ←←←←←←← Wake Event via Gateway API ←←←←←←←←←←←←←←←←←┘
    ↓
OpenClaw reads latest.json → Reports results to user

Setup (one-time)

1. Install Claude Code CLI

npm install -g @anthropic-ai/claude-code

2. Deploy Hook scripts

Run the setup script to install hooks and configure Claude Code:

bash scripts/setup.sh

This will:

Create ~/.claude/hooks/ directory
Install notify-openclaw.sh hook script
Create ~/.claude/settings.json with Stop + SessionEnd hooks registered

3. Configure environment

Set these in OpenClaw's environment or .env:

OPENCLAW_GATEWAY_URL=http://localhost:4152   # or your gateway URL
OPENCLAW_GATEWAY_TOKEN=your-token            # gateway auth token

Dispatching a Task

When user requests complex development work:

Step 1: Create task metadata

mkdir -p /tmp/claude-task
cat > /tmp/claude-task/task-meta.json << 'EOF'
{
  "description": "<user's request>",
  "workdir": "<target project directory>",
  "dispatched_at": "<ISO timestamp>",
  "session_key": "<current session key for callback>"
}
EOF

Step 2: Launch Claude Code in background

nohup claude -p "<user's detailed prompt>" \
  --output-format json \
  > /tmp/claude-task/task-output.json 2>&1 &
echo $! > /tmp/claude-task/pid

For complex multi-file tasks, add --agent-teams (if available) for parallel Lead/Dev/Test agent coordination.

Step 3: Respond immediately

Tell the user the task has been dispatched and they'll be notified on completion. Continue handling other requests.

Step 4: Handle callback

When the Wake Event arrives, read /tmp/claude-task/latest.json and report:

Task description and duration
Completed features
Test results (if any)
File changes summary

Important Notes

Zero Polling: Never loop/sleep to check Claude Code status. The hook handles notification.
Dual Hooks: Both Stop and SessionEnd are registered for reliability (normal completion + unexpected termination).
Token Efficiency: OpenClaw's context is not consumed while Claude Code works.
Error Handling: If the hook fails to fire, check /tmp/claude-task/task-output.json manually.
