<!-- ccr-slack-attribution --> _Requested by **Charis Lam** · [Slack thread](https://supabase.slack.com/archives/C0161K73J1J/p1790599888647059?thread_ts=1790599888.647059&cid=C0161K73J1J)_ ## Problem The weekly "Decrease studio lint ratchet baselines" workflow (`.github/workflows/studio-lint-ratchet-decrease.yml`) mechanically decreases each tracked ESLint rule's baseline count in `apps/studio/.github/eslint-rule-baselines.json` and opens/updates a PR. When a rule's count reaches exactly 0, there's nothing left to ratchet — a human (or agent) needs to remove it from ratchet tracking (`apps/studio/scripts/ratchet-rules.json` and the baseline file) and bump its ESLint severity to `error`, as was just done manually in #50977. Nobody is currently notified when this threshold is crossed, so it can sit unnoticed. ## Solution **Before:** the job silently commits the decreased baselines and opens/updates its PR with no signal that any rule just hit 0. **After:** a new step runs after the baseline commit/PR step, only when that step found changes (via a new `id: decrease-baselines` and a `changed` step output, added without touching the existing decrease logic itself — just capturing its existing control flow into an output). It parses the final `apps/studio/.github/eslint-rule-baselines.json` on disk for any rule whose count is exactly `0`. If any are found, it posts a Slack message via `curl` to a webhook, tagging `@Claude` in `#team-frontend` with the rule names and a link to the PR the job just created/updated, asking it to do the same triage as #50977 (remove from ratchet tracking, bump severity to `error`). If no rule is at 0, it skips silently. The webhook URL comes from a new repo secret, `secrets.SLACK_TEAM_FRONTEND_WEBHOOK_URL`, which **does not exist yet**. **A human needs to create a Slack incoming webhook for #team-frontend and add its URL as the `SLACK_TEAM_FRONTEND_WEBHOOK_URL` repository secret before this step will actually post anything.** Until then, the step detects the missing/empty secret and only logs a `::warning::`, exiting 0 — it will never fail the job. ## Review instructions 1. Read `.github/workflows/studio-lint-ratchet-decrease.yml`: confirm the existing decrease/commit/PR step is unchanged except for the added `id: decrease-baselines` and the two `echo ... >> "$GITHUB_OUTPUT"` lines that record whether anything changed and the PR URL. 2. Confirm the new final step only runs `if: steps.decrease-baselines.outputs.changed == 'true'`. 3. Confirm the new step parses `apps/studio/.github/eslint-rule-baselines.json`'s `rules` map for entries equal to `0`, and skips (exit 0, no curl) when none are found. 4. Confirm the `curl` call is gated on `SLACK_WEBHOOK_URL` being non-empty, and that a failed `curl` only emits `::warning::` rather than failing the step (`set -euo pipefail` is still safe because the failure is inside an `if !`). 5. Note that this PR alone does not make the notification fire: `SLACK_TEAM_FRONTEND_WEBHOOK_URL` must be provisioned as a repo secret (Settings → Secrets and variables → Actions) from a Slack incoming webhook for #team-frontend first. ## Checklist Check all before review: - [x] I have read [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) - [ ] If I wrote a new docs topic or edited an existing topic, I used the `/write-the-docs` or `/edit-the-docs` skill, which applies the docs [style guide](https://github.com/supabase/supabase/tree/master/apps/docs/style-guide) 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01LZThbcWV5U1r5cvUDKPVQP --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Charis Lam <26616127+charislam@users.noreply.github.com>

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.
- 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.
