Splits agent guidance into a lean monorepo-wide root file and a studio-specific file that Claude Code lazy-loads when working under `apps/studio/`. This keeps every session's baseline context small while giving studio work much richer, enforceable guidance. **Changed:** - `.claude/CLAUDE.md` — now monorepo-wide only: corrected pnpm version (10 → 11), expanded workspace table (design-system, ui-library, lite-studio, ui-patterns, api-types, pg-meta, shared-data), commands (`format`, `generate:types`, `api:codegen`), CI gates + never-hand-edit generated files, monorepo-wide conventions (incl. the named-exports rule, which lives in the shared eslint preset and applies to all six apps), and monorepo-wide skill triggers. Studio detail is replaced by a pointer to the nested file. Also corrects a long-standing error inherited from the old file: the `_Shadcn_` convention was inverted — `Button_Shadcn_` is the only suffixed export left and is rarely the right choice; primitives are unsuffixed. - `.claude/skills/studio-ui-patterns/SKILL.md` — removed the same stale `_Shadcn_` claim from the forms section (this skill also feeds CodeRabbit reviews). - `apps/studio/components/README.md` — component template now uses a named export, matching the lint-enforced convention (was the one doc still showing `export default`). - `apps/studio/TANSTACK_MIGRATION.md` — cleanup checklist gains an item to remove the migration section from `apps/studio/CLAUDE.md` when the migration finishes. - `.gitignore` — removed the blanket `CLAUDE.md` ignore rule (added in #40231 for personal local files, no longer used that way). Nested `CLAUDE.md` files are now tracked by default, so shared guidance can't silently fail to land. For *personal* notes, use `CLAUDE.local.md` (Claude Code loads it automatically alongside `CLAUDE.md`, and it's now gitignored here) — or `.git/info/exclude` if you prefer a different filename. **Added:** - `apps/studio/CLAUDE.md` — studio guidance, loaded on demand: mandatory skill routing (always load `studio-best-practices`, plus a task → skill table), TanStack Start migration rules (pages/routes mirroring, when a manual mirror is needed, never delete `pages/**` files), data-layer/state orientation, a default-to-shipping-tests-with-changes policy, and a "defaults that differ here" list (ESLint warning ratchet + local `lint:ratchet` command, `copyToClipboard` await rule, `useParams` from `common`, dayjs/sonner, `ui` vs `ui-patterns` import split, `@tanstack/react-table` over `react-data-grid`, etc.). ## Accuracy Every factual claim in both files (62 total) was verified against the code by parallel review agents instructed to refute each one. Results: 54 correct as written, 2 wrong (the inherited `_Shadcn_` inversion, and a fabricated `useExecuteSqlQuery` hook name — the real export is `useExecuteSqlMutation`), 6 imprecise (e.g. dayjs plugins load in both runtime entries, the ratchet counts occurrences regardless of severity). All fixed in this PR. ## Context cost | File | Size | When it loads | % of a 200k window | |---|---|---|---| | `.claude/CLAUDE.md` | 70 lines, ~1.2k est. tokens | every session | ~0.6% | | `apps/studio/CLAUDE.md` | 53 lines, ~1.6k est. tokens | only when touching studio files | ~0.8% | The always-loaded footprint grew only ~0.2k est. tokens vs the old 45-line file — everything studio-heavy sits behind the lazy load, so docs/www sessions pay nothing for it. Both files are well under Claude Code's large-file warning threshold (~40k chars) and the <200-line adherence guidance, with room to roughly double before it's worth worrying about. ## To test - Open a fresh Claude Code session from the repo root and read any file under `apps/studio/` — `apps/studio/CLAUDE.md` should get pulled into context automatically. - `git check-ignore apps/studio/CLAUDE.md` exits 1 (not ignored); `git check-ignore CLAUDE.local.md` exits 0 (ignored). - Skim both files — every claim has been code-verified (see Accuracy above), but a human sanity pass on the *judgment* calls (what's included/omitted) is welcome. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Refreshed monorepo onboarding conventions with updated tooling requirements, expanded inventory, standardized common scripts, and clearer CI gating and checks. * Added/updated Studio contributor guidance, including the TanStack Start migration rules and Studio development/testing/UI conventions. * Updated Studio component documentation to use named exports. * Refreshed the “Forms” UI pattern guidance and adjusted the referenced UI primitives. * **Chores** * Updated ignore rules so the primary top-level onboarding document is tracked. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Alaister Young <10985857+alaister@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.
- Kong is a cloud-native API gateway.
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.
