Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

Download the package from Yavira.
Extract it into a folder your agent can access.
Paste one of the prompts below and point your agent at the extracted folder.

New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

Skill Security Audit

MANDATORY security check before installing external skills. Inspired by the ClawHavoc campaign that compromised 341 malicious skills on ClawHub.

When to Use

Run this audit BEFORE any skill installation: clawhub install <skill> Manual skill download/copy Skills from GitHub, URLs, or untrusted sources

Quick Start

# Scan a skill folder python3 scripts/scan_skill.py /path/to/skill # JSON output for automation python3 scripts/scan_skill.py /path/to/skill --json # Exit code 0 only if SAFE python3 scripts/scan_skill.py /path/to/skill --install-if-safe

🟡 WARNING (Review Required)

Only patterns that are suspicious regardless of skill type: Raw socket usage (unusual for most skills) Dynamic code compilation File/directory deletion Screenshot/keyboard capture libraries Low-level system calls (ctypes)

Philosophy

We intentionally don't warn on common patterns like: HTTP requests (normal for API skills) API key references (normal for integration skills) File writes (normal for data skills) Environment variable access (normal for config) This reduces noise so real threats stand out.

Integration with clawhub

Create a wrapper script to auto-scan before installation: #!/bin/bash # clawhub-secure: Scan before install SKILL="$2" TEMP="/tmp/skill-audit-$$" # Fetch without installing clawhub inspect "$SKILL" --out "$TEMP" # Scan python3 /path/to/scan_skill.py "$TEMP" --install-if-safe if [ $? -eq 0 ]; then clawhub install "$SKILL" else echo "🔴 Installation blocked by security scan" exit 1 fi rm -rf "$TEMP"
