supabase
by alinaqiThe supabase skill helps you manage Supabase-backed apps with a local-first workflow for database changes, auth, storage, Edge Functions, migrations, and RLS. Use this supabase guide when you want practical supabase usage, install guidance, and repeatable deployment steps instead of ad hoc production edits.
This skill scores 81/100, which means it is a solid directory listing for users working with Supabase and likely worth installing if they want guided CLI and migration workflows instead of generic prompting. The repository provides enough operational detail to reduce guesswork, though it is not a complete turnkey automation package.
- Clear trigger and scope for Supabase database, auth, storage, and Edge Functions work.
- Strong operational guidance around local-first development, migrations in version control, and CLI commands such as init and link.
- Substantial skill body with workflow sections, constraints, and concrete examples, which helps agents execute with less ambiguity.
- No install command or companion files/scripts, so adoption relies on reading the SKILL.md guidance directly.
- Evidence shows no support files or references bundle, which limits verification and may leave some edge cases underspecified.
Overview of supabase skill
What the supabase skill is for
The supabase skill helps you work on Supabase-backed apps with a local-first workflow: database changes, auth, storage, Edge Functions, and deployment through migrations instead of manual production edits. It is best for readers who need a practical supabase guide for backend development, not a generic prompt about PostgreSQL.
Who should install it
Use this supabase skill if you are building or maintaining a project that already uses Supabase, or you need to turn a rough product idea into a structured local dev workflow. It is most useful when you care about schema changes, RLS, environment setup, and keeping local and remote state aligned.
What makes it different
The main value is process, not theory: supabase install guidance, CLI setup, linking to a remote project, and disciplined migration flow. That makes it a better fit than freeform prompting when you want fewer ad hoc database edits and more repeatable changes.
How to Use supabase skill
Install and open the right files
Install the skill in your skills directory, then start with SKILL.md and the project’s supabase/ folder. In the repo provided here, there are no helper scripts or extra reference folders, so the first read should focus on the core instructions, not on hunting for hidden tooling.
Give the skill the right input
For best results, prompt with the exact Supabase job you want done, the project type, and any constraints. Good inputs look like: “Add a profiles table with RLS for a SaaS app,” “Create an Edge Function for webhook verification,” or “Diagnose why local auth works but remote login fails.” Weak inputs like “fix Supabase” usually produce generic output.
Follow the local-first workflow
Use the skill to plan changes locally first: initialize Supabase, make schema edits as migrations, test with the CLI, then link and push only when the local result is correct. If you are working on an existing project, ask the skill to infer whether you should inspect supabase/config.toml, supabase/migrations/, and supabase/seed.sql before changing anything.
Read these sources first
Start with SKILL.md, then inspect the Supabase CLI docs linked there if you need command-level detail. For your own project, prioritize supabase/config.toml, existing migrations, seed data, and any environment files mentioned in the skill paths. Those files usually determine whether the output is actually usable.
supabase skill FAQ
Is supabase only for backend development?
Mostly yes. The supabase skill is strongest for backend development tasks like database design, RLS, auth flows, storage policies, and Edge Functions. It is not a full replacement for frontend architecture help.
Do I need to know Supabase before using it?
No, but you should be able to describe the outcome you want. The skill is beginner-friendly if you can say what table, policy, function, or auth flow you need. If you cannot define the data model or access rules, expect to spend extra time refining the prompt.
How is this different from a normal prompt?
A normal prompt may explain Supabase features in isolation. This supabase skill is meant to guide implementation decisions: how to set up locally, how to keep migrations clean, and how to avoid direct production edits. That makes it better when you want a working change, not just an explanation.
When should I not use this skill?
Do not use it if you are only asking a one-off conceptual question with no project context, or if your stack is not actually Supabase-based. It is also a poor fit if you want UI-heavy frontend work without any database, auth, or function changes.
How to Improve supabase skill
Provide the exact Supabase surface area
The best improvements come from naming the specific surface: database schema, RLS policies, auth settings, storage buckets, realtime subscriptions, or Edge Functions. The more precisely you scope the task, the less the skill has to guess and the more useful the output will be.
Share the current state before asking for changes
If a table, policy, or function already exists, include the current SQL, migration name, or error message. This matters because supabase usage often fails at the boundary between local and remote state, and the skill can only help if it knows what is already deployed.
Ask for implementation, not just advice
Request concrete artifacts: migration SQL, policy definitions, CLI commands, or a step-by-step supabase install and deploy sequence. If the first answer is too broad, iterate by asking for one narrower deliverable, such as “rewrite this as a migration” or “add the missing RLS policy only.”
Watch for the common failure modes
The usual problems are vague prompts, missing project context, and mixing local and production changes in one request. If you want reliable results from the supabase skill, keep environment details visible, avoid assuming default policies, and specify whether the target is a greenfield project or an existing Supabase app.
