AIDefence security layer with prompt injection blocking, input validation, sandboxed execution, output sanitization, and STRIDE threat modeling.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
- When processing untrusted inputs - Security audits of agent-generated code - Compliance verification (OWASP Top 10, CIS) ## AIDefence Layers 1. **Prompt Injection Detection** - Pattern + heuristic blocking 2. **Input Validation** - Path traversal, type coercion, parameter sanitization 3. **Static Analysis (SAST)** - Vulnerability scanning, CWE matching 4. **Sandboxed Execution** - Network isolation, filesystem restrictions, resource limits 5. **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 | ## Agents Used - `agents/security-auditor/` - Vulnerability detection - `agents/reviewer/` - Code quality verification ## Tool Use Invoke via babysitter process: `methodologies/ruflo/ruflo-security-audit`

How to install
mdr add a5c-ai/babysitter/security-hardening@sha256:dbb944f6e23df6baThe line at the top of this page pins the label git:20260601.da7723a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
