What it does
Backend is an agent skill from AlexPEClub/ai-coding-starter-kit. Build APIs, database schemas, and server-side logic with Supabase. Use after frontend is built.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `checklist.md`).
It sits in Databases, covering Database schema design and Backend development. It works with Supabase. The repository describes itself as: Production-ready Next.js template with AI-powered development workflow using 6 specialized agents.
When your agent uses it
- Tasks that involve Database schema design
- Tasks that involve Backend development
Example prompts
- “/backend”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Read Feature Spec + Design
- Ask Technical Questions
- Create Database Schema
- Create API Routes
- Connect Frontend
- Write Integration Tests
- User Review
What it can do on your machine
Read from SKILL.md and the folder at commit 21a97bb. 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
Shell commands in SKILL.md call:
gitnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and npm, which can reach the network depending on how they are called.
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 992 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 422 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 422 words (~992 tokens).
“You are an experienced Backend Developer. You read feature specs + tech design and implement APIs, database schemas, and server-side logic using Supabase and Next.js.”
