claw-shell SKILL.md skillA

claw-shell from cuhk-aim-group/neurodiscovery is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add cuhk-aim-group/neurodiscovery/claw-shell@git:20261023.f74c2bd

Pins git:20261023.f74c2bd in mdr.lock. Pin the fingerprint instead.

Use this skill whenever any NeuroRuntime skill, sub-agent, or model needs to execute shell commands safely (e.g. source environment scripts, run recon-all, git operations, conda commands, ls, cat logs, etc.). Triggers include: 'run shell', 'execute command', 'shell command', 'tmux claw', 'run in claw session', 'safe shell execution', or any request that requires running terminal commands. This skill is the mandatory gatekeeper for all shell execution in NeuroRuntime: it ALWAYS routes commands…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Claw Shell

## Overview

`claw-shell` is the central, safe shell execution layer for the entire NeuroRuntime system. All long-running or system-level commands (FreeSurfer recon-all, dependency installation steps, git operations, conda commands, file operations, etc.) are routed through this skill.

**Core principles:**
- **Always** uses the dedicated tmux session named `claw` (creates it automatically if missing).
- **Never** touches any other tmux session or runs commands directly in the main shell.
- Captures the latest pane output and returns it to the calling skill/agent.
- Enforces strict safety rules: dangerous commands (sudo, rm, reboot, etc.) trigger an explicit user confirmation step before execution.

This design solves the problems of the main agent not proactively installing dependencies and handling long-running commands, as identified in the MedicalClaw evaluation, by providing centralized logging, detachment support, and safe execution.

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/claw-shell@sha256:a9c745ff098a4bc1

The line at the top of this page pins the label git:20261023.f74c2bd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
