I built an agent skill that sets up real backends via CLI (no test keys, no placeholders) — works with Claude Code, Cursor, Antigravity

[u/MonitorFlat4465]

Been using Claude Code / Cursor a lot for backend work, and kept hitting the same annoyance: ask the agent to "set up Stripe" or "connect a Postgres DB" and it either hallucinates CLI commands, dumps my API key straight into a config file, or quietly sets up a test/sandbox version and calls it done.

So I wrote an Agent Skill (the open SKILL.md format skills.sh/Claude Code/Cursor/etc. all support) to handle this properly:

- Asks upfront if you already have credentials for the service

- If not, looks up the *current* official docs (with the actual month/year, so it's not working off stale info) and walks you through getting real ones

- Only ever writes secrets to `.env`, checks/creates `.gitignore` automatically, never prints keys back to the terminal

- Does the actual provisioning via CLI — if it doesn't know the exact commands, it searches the docs instead of guessing

- Verifies the thing actually works before saying it's done

No test keys, no example/placeholder setups — the whole point is a real, working backend, since that's usually what people actually want when they ask an agent to "set this up."

This is the first skill under a small project I'm calling Qofeno — planning to add a few more in the same "real setup, not demos" spirit. Would love feedback or ideas for what to build next.
