Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00136 | $0.01328 |
| Opus 5 | $0.00068 | $0.00664 |
| Sonnet 5 | $0.00027 | $0.00266 |
| Haiku 4.5 | $0.00014 | $0.00133 |
Grade D, and why
claw-shell scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
| Dangerous (requires confirmation) | `rm -rf ...`, `sudo apt install ...`, `docker system prune -a` | Asks user “YES” before proceeding | Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Claw Shell
Overview
claw-shell is the central, safe shell execution layer for the entire NeuroClaw 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.
Quick Reference
| Type | Example Commands | Behavior |
|---|---|---|
| Safe (direct run) | ls -la, cat log.txt, git status |
Executes immediately in claw session |
| Environment setup | source $FREESURFER_HOME/SetUpFreeSurfer.sh |
Executes and returns output |
| Long-running pipeline | recon-all -subjid sub-001 -all -parallel |
Runs in background-capable tmux pane |
| Dangerous (requires confirmation) | rm -rf ..., sudo apt install ..., docker system prune -a |
Asks user “YES” before proceeding |
Tool Interface
Tool name: claw_shell_run
Input:
command(string, required): the full shell command to run inside theclawtmux session.
Installation
This is a core NeuroClaw skill and requires no external packages beyond tmux.
One-time setup (run once via dependency-planner or manually):
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

claw-shell is a skill published in the GitHub repository CUHK-AIM-Group/NeuroClaw (83 stars, last pushed 2d ago), licensed MIT. It adds 136 tokens to every session and 1,328 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
