security-hardening
SkillSecurityThis skill adds a security layer to your AI agent. With it in place, your agent blocks prompt injection attempts, validates the inputs it receives, and sanitizes its outputs. It can also run tasks in a sandbox and use STRIDE threat modeling to check for weaknesses.
Available today. Use it from your connected AI after setup.
No other account needed.
Add the skill to your agent, then keep using it as you normally would. The security checks run in the background with no extra setup.
Then ask your AI: use the security-hardening skill
What your AI can do with it
- Block prompt injection attempts before they affect your agent
- Validate incoming inputs for unsafe content
- Run agent tasks inside a sandbox so risky operations stay contained
- Sanitize outputs before they leave your agent
- Apply STRIDE threat modeling to spot potential weaknesses
What this skill tells your AI
The instructions your AI receives, as published by a5c-ai/babysitter in library/methodologies/ruflo/skills/security-hardening/SKILL.md and read by ahel’s review.
- When processing untrusted inputs
- Security audits of agent-generated code
- Compliance verification (OWASP Top 10, CIS)
AIDefence Layers
- Prompt Injection Detection - Pattern + heuristic blocking
- Input Validation - Path traversal, type coercion, parameter sanitization
- Static Analysis (SAST) - Vulnerability scanning, CWE matching
- Sandboxed Execution - Network isolation, filesystem restrictions, resource limits
- Output Sanitization - Secrets, PII, injection vector redaction
Security Levels
| Level | Layers | Use Case |
|---|---|---|
| standard | SAST + validation + sanitization | Routine audits |
| elevated | + threat modeling + compliance | Pre-release audits |
| maximum | + sandbox + full STRIDE + remediation | Critical systems |
