backend-guidance from n-n-code/n-n-code-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add n-n-code/n-n-code-skills/backend-guidance@git:20260904.6c1f699Pins git:20260904.6c1f699 in mdr.lock. Pin the fingerprint instead.

Baseline overlay for routine thin HTTP, gRPC, or message-consumer implementation and review; use `backend-systems-guidance` for multi-layer, data-access, transaction, reliability, or trust-boundary work. Compose with matching implementation guidance. Not for outbound-client-only or security-audit tasks.
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
# Backend Guidance This is a composable overlay, not a standalone workflow. Use alongside the matching principle skill (for example, `coding-guidance-cpp`) when the change touches backend code. Add `project-core-dev` only when repository-specific completion checks still need to be discovered or reported. Choose the activity before applying the rules below: - for implementation, make only the requested backend changes and validate them - for review, inspect and report prioritized findings with evidence; do not edit files or require findings to be fixed unless the user also asks for remediation Use this as the thin default backend overlay for ordinary backend work. If the task includes service-boundary refactors, repository or transaction work, queue or webhook reliability, stronger testing expectations, or explicit trust-boundary hardening, prefer `backend-systems-guidance`. Routing examples: - thin route handler that delegates to existing service logic -> use this skill - small message consumer bug fix with no retry or persistence redesign -> use this skill - new endpoint with authz, repository, transaction, retry, or observability …

How to install
mdr add n-n-code/n-n-code-skills/backend-guidance@sha256:6598c10b2c326f0cThe line at the top of this page pins the label git:20260904.6c1f699, 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.
