Backend — stack, logic, data, operations, rot

SkillDatabases & data

Backend engineering judgment, distilled from a stronger model - invoke when CHOOSING a tech stack, language, database, queue, or architecture; designing a service, API, business logic, or schema; making a system production-ready (observability, failure handling, security); or reviewing server-side code and judging codebase health. Scenario-driven stack tradeoffs, logic-design rules, data discipline, production floors, and a rot catalog (the early signs of unmaintainable code).

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Backend — stack, logic, data, operations, rot skill

What this skill tells your AI

The instructions your AI receives, as published by telagod/code-abyss in skills/_kernel/backend/SKILL.md and read by ahel’s review.

Rule content lives in the five files below; this SKILL.md only routes (doctrine/04-maintenance.md governs edits to this bundle too).

Route by moment

You are about to…Read (in this folder)
Pick a language / framework / DB / queue / architecture, or judge a stack proposalstack.md
Design or review a service, module, API, or piece of business logiclogic.md
Design a schema, transaction, migration, or cachedata.md
Ship to production — observability, config, failure modes, security, jobs, limitsoperate.md
Review existing code, plan a refactor, or explain why a codebase feels dangerousrot.md

Starting a new system usually means stack.mdlogic.mddata.md, in that order: stack only after the scenario interrogation, endpoints only after the data model.

Scope and neighbors

Server-side engineering judgment only. Whether to delegate and when to escalate → doctrine; how to investigate/verify anything → methods; the visual/UI layer → frontend.

The stance

The one test governing the whole bundle is logic.md's opening line — is change still cheap and safe — and rot.md's opening defines the failure mode and the ugly-but-safe tiebreak. Read those two openings before judging any backend.
