SKILL.md — Claw Core Runtime (Exec Wrapper)

Use claw_core for session-managed command execution instead of raw exec. OpenClaw agents should prefer this when claw_core is available.

What This Skill Is For

When an agent needs to run shell commands, use claw_core (Terminal Runtime Layer) instead of direct exec:

• •Session isolation — each command runs in a managed session
• •Timeout enforcement — prevents runaway processes
• •Structured output — stdout, stderr, exit_code, duration
• •Graceful fallback — if claw_core is unavailable, fall back to normal exec

How to Run Commands via claw_core

Wrapper Script (plugin-installed)

The plugin ships claw_core_exec.py. When installed at $PLUGIN_ROOT:

python3 $PLUGIN_ROOT/scripts/claw_core_exec.py --cwd /path/to/dir --timeout 60 -- ls -la

Or with CLAW_CORE_SOCKET set:

CLAW_CORE_SOCKET=/tmp/trl.sock python3 claw_core_exec.py --timeout 60 -- npm install

One-Shot Pattern

The wrapper creates a session, runs the command, then destroys the session. No need to manage sessions manually for simple commands.

When claw_core Is Unavailable

• •Check socket: ls -la /tmp/trl.sock (or $CLAW_CORE_SOCKET)
• •Start daemon: openclaw clawcore start or via plugin boot hook
• •Fall back to normal exec if claw_core is down

Config (OpenClaw)

Enable this skill and ensure exec tool uses the wrapper when available. Plugin config (plugins.entries.claw-core.config):

• •socketPath: Unix socket path (default /tmp/trl.sock)
• •binaryPath: path to claw_core binary (optional)
