salmanrf 8696762b4b fix(www): keep committed agent-skills index when fetch fails outside production (#50556)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Bug fix (build resilience)

## What is the current behavior?

`apps/www/scripts/fetchAgentSkills.mjs` runs as part of `content:build`
and fails the whole `www` build (and `pnpm dev:www`) whenever the GitHub
API call fails. #50106 added `AGENT_SKILLS_GITHUB_TOKEN` to mitigate
rate limits on Vercel, but that does not cover local runs or builds
where the env var is not available (e.g. fork PRs).

Example from a local `pnpm dev:www` hitting the unauthenticated rate
limit:

```
www:dev: Error: GET https://api.github.com/repos/supabase/agent-skills/releases/latest → 403
www:dev: at fetchJson (file:///.../apps/www/scripts/fetchAgentSkills.mjs:38:22)
www:dev: at process.processTicksAndRejections (node:internal/process/task_queues:105:5)
www:dev: at async main (file:///.../apps/www/scripts/fetchAgentSkills.mjs:53:19)
```

## What is the new behavior?

`public/.well-known/agent-skills/index.json` is already committed to the
repo, so when the fetch fails and `VERCEL_ENV` is not `production`, the
script logs the error, keeps the committed file, and exits 0:

```
www:dev: Error: GET https://api.github.com/repos/supabase/agent-skills/releases/latest → 403
www:dev: ...
www:dev: Fetch failed — keeping committed public/.well-known/agent-skills/index.json
```

Production builds still fail loudly so a stale skills list is never
silently shipped.

Verified locally by forcing a 401 with a bad token:

- `VERCEL_ENV=preview` exits 0 and keeps the committed `index.json`
- `VERCEL_ENV=production` exits 1

## Additional context

Follow-up to #50106.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
