Security Hardening
DevOps & Securitysecurity-hardeningSecurity Hardening is an Agent Skill for devops & security published in the a5c-ai/babysitter repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
AIDefence security layer with prompt injection blocking, input validation, sandboxed execution, output sanitization, and STRIDE threat modeling.
QUICK START
How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/a5c-ai/babysitter/blob/HEAD/library/methodologies/ruflo/skills/security-hardening/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/security-hardening, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
- 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 |
