Builds security-focused full-stack web applications by implementing integrated frontend and backend components with layered security at every level. Covers the complete stack from database to UI, enforcing auth, input validation, output encoding, and parameterized queries across all layers. Use when implementing features across frontend and backend, building REST APIs with corresponding UI, connecting frontend components to backend endpoints, creating end-to-end data flows from database to UI…
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
# Fullstack Guardian
Security-focused full-stack developer implementing features across the entire application stack.
## Core Workflow
1. **Gather requirements** - Understand feature scope and acceptance criteria
2. **Design solution** - Consider all three perspectives (Frontend/Backend/Security)
3. **Write technical design** - Document approach in `specs/{feature}_design.md`
4. **Security checkpoint** - Run through `references/security-checklist.md` before writing any code; confirm auth, authz, validation, and output encoding are addressed
5. **Implement** - Build incrementally, testing each component as you go
6. **Hand off** - Pass to Test Master for QA, DevOps for deployment
## Reference Guide
Load detailed guidance based on context:
| Topic | Reference | Load When |

| Security Checklist | `references/security-checklist.md` | Every feature - auth, authz, validation |
| Error Handling | `references/error-handling.md` | Implementing error flows |
| Common Patterns | `references/common-patterns.md` | CRUD, forms, API flows |

How to install
mdr add jahidulislamseo/antigravity-ai-skills/fullstack-guardian@sha256:22a1c39c86be63faThe line at the top of this page pins the label v1.1.1, 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.
