What it does

Backend Services is an agent skill from biersoeckli/QuickStack. Create and update QuickStack backend services, adapters, standalone services, and server actions using the project's established singleton, adapter, caching, and error-handling patterns. Use when editing files under src/server/services, src/server/adapter, src/server/utils, src/server.ts, or related server-side actions and backend utilities.

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `REFERENCE.md`).

It sits in Backend & APIs, covering Caching and Backend development. It works with Prisma. The repository describes itself as: Open-source, self-hostable alternative to Vercel, Netlify, Railway and Heroku. Self-host any app on your own servers in minutes. The licence is GPL-3.0.

When your agent uses it

  • Editing files under src/server/services
  • Src/server/adapter
  • Src/server/utils
  • Related server-side actions and backend utilities

Example prompts

  • “/backend-services”

What it can do on your machine

Read from SKILL.md and the folder at commit 9c74e91. 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 Services loads about 552 tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 227 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~552

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
Create and update QuickStack backend services, adapters, standalone services, and server actions using the project's established singleton, adapter, caching, and error-handling patterns. Use when editing files under src/server/services, src/server/adapter, src/server/utils, src/server.ts, or related server-side actions and backend utilities.

Backend Services

Quick Start

For QuickStack backend work, follow the existing service architecture:

  • Use one class per file with a default-exported singleton instance.
  • Keep service dependencies as module imports of other singleton services or adapters.
  • Route Prisma and external API access through adapters, not directly from services.
  • Throw ServiceException or FormValidationException for expected domain failures.
  • After a mutation affecting cached reads, invalidate the matching tags in finally.

Service Pattern

When creating or editing a service:

  • Put business logic in src/server/services/.
  • Export a singleton instance as the file default export.
  • Accept primitives or shared model types as inputs.
  • Import dependencies at module scope; do not instantiate sibling services.

Adapters And Actions

  • Put external integrations in src/server/adapter/ using the same singleton export pattern.
  • Use adapters for Prisma, Kubernetes, S3, and Longhorn access.
  • Wrap server actions with simpleAction or saveFormAction.
  • Perform authorization checks inside the action callback before calling the service.

Mutation Rules

  • After a mutation affecting cached reads, call revalidateTag() in finally.
  • Use the matching Tags.* helper; never hardcode cache tag strings.
  • Use transactions when multiple writes must succeed or fail together.

Standalone Services

  • Place cron and background jobs in src/server/services/standalone-services/.
  • Register cron jobs with scheduleService.
  • Wrap cron callback bodies in try/catch and log errors instead of rethrowing.
  • Initialize standalone services from src/server.ts.

Reference

See REFERENCE.md for concrete patterns covering adapters, actions, authorization, Prisma, caching, naming, and startup wiring.
