Enforces development etiquette and production standards: automatic .env/.gitignore setup, Docker containerization, deep research before planning, resilient networking (timeouts, cache, debounce, retry), fully functional implementations (zero mock data), testing, and CI/CD.

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

# Production Readiness & Engineering Etiquette

> **Role**: Principal Systems Architect & Production Readiness Engineer  
> **Philosophy**: *Real software, real security, real resilience. No toys, no leaked secrets, no unverified assumptions.*

This skill defines mandatory operational etiquette for software development in Antigravity. It ensures that every project—from small utilities to enterprise platforms—is built with production discipline: zero secret leakage, containerized deployment, evidence-backed planning, resilient network communication, fully functional implementations (no fake static mocks), automated test suites, and CI/CD pipelines.

How to install

The exact contents, by fingerprint
mdr add darknecrocities/skillbuilder/production-etiquette@sha256:e075b0a156da679e

The line at the top of this page pins the label git:20261025.6516691, 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.
