software-backend from vasilyu1983/ai-agents-public is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vasilyu1983/ai-agents-public/software-backend@v1.3Pins v1.3 in mdr.lock. Pin the fingerprint instead.

Builds backend services and APIs with durable defaults. Use when implementing REST, GraphQL, tRPC, or gRPC services with auth, queues, data, or observability.
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
# Software Backend Engineering Use this skill for backend service implementation and review: API boundaries, auth, data access, jobs, caching, observability, and production hardening. If the main question is platform selection, system topology, or API-contract design without implementation, hand off early. ## Quick Reference | Need | Default Direction | |------|-------------------| | Public HTTP API | REST with explicit contracts and timeouts | | Internal TS monorepo API | tRPC when end-to-end type safety matters | | High-throughput internal RPC | Connect by default; plain gRPC only when you don't need browser/gRPC-Web compatibility | | Complex client-shaped reads | GraphQL | | Relational data | PostgreSQL with migrations and pooling | | Background work | Queue plus idempotent handlers and DLQ policy | | Browser auth | OIDC (authorization code with PKCE) plus httpOnly cookies | | Service auth | prefer workload identity (cloud IAM, SPIFFE) over long-lived static credentials where the platform provides it; short-lived tokens or signed service credentials when it isn't available (multi-cloud, third-party, legacy) | | Caching | explicit TTLs and invalidation rules | …

How to install
mdr add vasilyu1983/ai-agents-public/software-backend@sha256:c53fa05f880d86e8The line at the top of this page pins the label v1.3, 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.
