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.

Documentation
safe-web
Secure web fetch and search with PromptGuard scanning.
Status
✅ Working
Purpose
Protects against prompt injection attacks hidden in web content before returning it to the AI. Wraps web fetching and searching with security scanning.
Installation
Requires PromptGuard and Python dependencies: # Install PromptGuard first cd /home/linuxbrew/.openclaw/workspace/skills/prompt-guard pip3 install --break-system-packages -e . # Install web dependencies (if not present) pip3 install --break-system-packages requests beautifulsoup4
Fetch Command
Fetch a URL and scan the content: # Basic fetch safe-web fetch https://example.com/article # Save to file safe-web fetch https://example.com --output article.txt # JSON output for automation safe-web fetch https://example.com --json # Strict mode (block on MEDIUM) safe-web fetch https://example.com --strict
Search Command
Search the web and scan results: # Basic search safe-web search "AI safety research" # More results safe-web search "stock market news" --count 10 # JSON output safe-web search "machine learning" --json
Exit Codes
CodeMeaning0Success - content/results are clean1Error (network, parsing, etc.)2Threat detected - content blocked
Environment Variables
BRAVE_API_KEY - API key for Brave Search (optional, enables search command) Get one at: https://brave.com/search/api/
Symlink (Recommended)
Create a system-wide symlink so safe-web works from any directory: sudo ln -s /home/linuxbrew/.openclaw/workspace/skills/safe-web/scripts/safe-web.py /usr/local/bin/safe-web After creating the symlink, you can use safe-web directly without specifying the full path.
Fetch Flow
Downloads URL content with requests Extracts text using BeautifulSoup (removes scripts, styles) Scans extracted text with PromptGuard Returns clean content or blocks with SHIELD report
Search Flow
Queries Brave Search API (requires API key) Scans each result title and description Filters out suspicious results Returns only clean results
Security Model
Fail-closed: If PromptGuard cannot be loaded or scanning fails, the tool reports an error rather than returning unverified content. Content sanitization: HTML is parsed and scripts/styles are removed before scanning to reduce false positives. No execution: This tool only fetches and scans. It never executes JavaScript or runs commands found in web content.

When to Use
Use safe-web when: Fetching content from untrusted URLs Scraping web pages for analysis Searching and processing web results Any web content will enter the AI context window Use standard web_fetch/web_search tools only for: Trusted, known-safe domains Internal documentation sites When you explicitly want to bypass scanning
