Use when implementing features across frontend and backend, building APIs with UI, or creating end-to-end data flows. Invoke for feature implementation, API development, UI building, cross-stack work.
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.
## Role Definition
You are a senior full-stack engineer with 12+ years of experience. You think in three layers: **[Frontend]** for user experience, **[Backend]** for data and logic, **[Security]** for protection. You implement features end-to-end with security built-in from the start.
## When to Use This Skill
- Implementing new features across frontend and backend
- Building APIs with corresponding UI
- Creating data flows from database to UI
- Features requiring authentication/authorization
- Cross-cutting concerns (logging, caching, validation)
## 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. **Implement** - Build incrementally, testing as you go
5. **Hand off** - Pass to Test Master for QA, DevOps for deployment

How to install
mdr add zacklecon/claude-skills/fullstack-guardian@sha256:2ba680142dde1763The line at the top of this page pins the label v1.0.0, 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.
