What it does
Backend is an agent skill from telagod/code-abyss. 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).
Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `data.md`, `logic.md` and `operate.md`).
It sits in DevOps & Cloud, covering Backend development and Observability. The repository describes itself as: Give your AI coding agent a personality. Composable persona + style + skills for Claude Code, Codex, Gemini CLI & OpenClaw. Ships Tech Persona Card v1.0 spec. The licence is MIT.

Example prompts
- “/backend”
What it can do on your machine
Read from SKILL.md and the folder at commit 2544577. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Backend loads about 469 tokens when it runs. Until then it costs about 122 tokens; SKILL.md has 181 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- 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.

Backend — stack, logic, data, operations, rot
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 proposal | stack.md |
| Design or review a service, module, API, or piece of business logic | logic.md |
| Design a schema, transaction, migration, or cache | data.md |
| Ship to production — observability, config, failure modes, security, jobs, limits | operate.md |
| Review existing code, plan a refactor, or explain why a codebase feels dangerous | rot.md |
Starting a new system usually means stack.md → logic.md → data.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.

Questions about Backend
What does Backend do?
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…. Backend is an agent skill from telagod/code-abyss. 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.
When should I use Backend?
Backend fits situations like: tasks that involve Backend development; tasks that involve Observability.
How do I install Backend in Claude Code?
Run `npx skills add telagod/code-abyss --skill backend -a claude-code`. Or copy the skill folder (skills/_kernel/backend in telagod/code-abyss) into .claude/skills/backend in your project. Claude Code loads it when a task matches its description.
How do I install Backend in Codex?
Run `npx skills add telagod/code-abyss --skill backend -a codex`. Or copy the skill folder (skills/_kernel/backend in telagod/code-abyss) into .agents/skills/backend in your project. Codex loads it when a task matches its description.
Can I use Backend in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add telagod/code-abyss --skill backend -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/backend, .gemini/skills/backend, .github/skills/backend and .opencode/skills/backend in your project.
What does Backend need to run?
SKILL.md names no scripts, command-line tools or credentials: Backend is instructions for the agent only.
Does Backend access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Backend safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Backend use?
Backend is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Backend use?
About 469 tokens (SKILL.md is roughly 1.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Backend?
Skills that share tags, products or a category with Backend: Otel Python (ollygarden/opentelemetry-agent-skills, 106 stars), Otel Java (ollygarden/opentelemetry-agent-skills, 106 stars), AI Observability (rrezartprebreza/spring-boot-skills, 298 stars) and Production Observability (rrezartprebreza/spring-boot-skills, 298 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Backend?
telagod (a GitHub user) maintains it in telagod/code-abyss, which has 243 GitHub stars. The repository holds 38 skills in this directory. The repository was last updated on July 19, 2026.
