What This Skill Does
Screens untrusted text for prompt injection, data exfiltration, and tool-abuse patterns before it reaches memory or other tools. Assigns a severity score and routes content to either acceptance or quarantine. Includes a safe memory append workflow that enforces scan and lint checks before any write.
Intercepts malicious content at the boundary rather than relying on downstream tools to handle hostile input safely.
When to use it
- Scanning email content before summarizing it to an agent
- Screening scraped web pages before feeding them into a pipeline
- Quarantining social media replies that contain suspicious instructions
- Enforcing sanitized memory writes when processing user-supplied input
- Blocking exfiltration attempts hidden in LLM-targeted document payloads
Example Workflow
Here's how your AI assistant might use this skill in practice.
INPUT
User asks: scan this webpage content before summarizing it
AGENT
- 1Pass the raw fetched text to the scan step
- 2Receive severity score and flag list from the scanner
- 3Check if severity is medium or higher
- 4If severity is medium+, route content to quarantine and halt pipeline
- 5If severity is low, proceed to summarize the sanitized text
OUTPUT
Content is either quarantined with a report or cleared for downstream use
