Scenario-driven stack tradeoffs, logic-design rules, data discipline, production floors, and a rot catalog (the early signs of unmaintainable code).\n---\n\n# Backend — stack, logic, data, operations, rot\n\nRule content lives in the five files below; this SKILL.md only routes\n(`doctrine/04-maintenance.md` governs edits to this bundle too).\n\n## Route by moment\n\n| You are about to… | Read (in this folder) |\n|---|---|\n| Pick a language / framework / DB / queue / architecture, or judge a stack proposal | `stack.md` |\n| Design or review a service, module, API, or piece of business logic | `logic.md` |\n| Design a schema, transaction, migration, or cache | `data.md` |\n| Ship to production — observability, config, failure modes, security, jobs, limits | `operate.md` |\n| Review existing code, plan a refactor, or explain why a codebase feels dangerous | `rot.md` |\n\nStarting a new system usually means `stack.md` → `logic.md` → `data.md`, in that order:\nstack only after the scenario interrogation, endpoints only after the data model.\n\n## Scope and neighbors\n\nServer-side engineering judgment only. Whether to delegate and when to escalate →\n`doctrine`; how to investigate/verify anything → `methods`; the visual/UI layer →\n`frontend`.\n\n## The stance\n\nThe one test governing the whole bundle is `logic.md`'s opening line — is change still\ncheap and safe — and `rot.md`'s opening defines the failure mode and the ugly-but-safe\ntiebreak. Read those two openings before judging any backend.\n","tagline":"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 rev","category":"security","tags":["agent-skill"],"author":"telagod","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"telagod/code-abyss","creatorName":"telagod","creatorUrl":"https://github.com/telagod","sourceUrl":"https://github.com/telagod/code-abyss/tree/main/skills/_kernel/backend","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/telagod-backend#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
