Charis 9ae8432dc7 refactor(studio): migrate create, delete, and run notebook tools to tool contracts (#51754)
## Summary

Migrates the create, delete, and run notebook assistant tools to the
tool contract + server pattern used by `update_notebook`. Each tool now
defines its schema once in a shared contract, with server-only execution
split into a `.server.ts` module. This removes duplicated client-side
schemas and gives the three tools one shared notebook mutation output
schema.

## Changes

- Add `create-notebook`, `delete-notebook`, and `run-notebook` tool
contracts, each with a `.server.ts` implementation.
- Remove the duplicated client-side schemas for these tools from
`notebook-tools.ts` and the registry.
- Add `notebook-mutation-output.ts` as the single output schema shared
by the notebook mutation tools.
- Add `lib/ai/opt-in-level.ts` with the opt-in level helpers, extracted
from the existing module to break an import cycle.
- Add optional `ToolContract.outputOnInvalid` so `run_notebook` history
replay can reuse a stored output when input fails validation.
- Update the AI assistant panel renderers (proposal, run, opt-in modal
and request) and the tool filter, sanitizer, and cache invalidation to
use the new contracts.

## Deviations worth reviewing

- **`outputOnInvalid` on `ToolContract`.** This is a new optional hook.
It exists so `run_notebook` history replay can return a valid output
when stored input no longer passes validation. Reviewers should confirm
this is the right level for the hook rather than handling it inside the
tool.
- **`opt-in-level.ts` extraction.** The helpers were moved into their
own module to break a circular import between the tool modules and the
opt-in components. This adds one file, but no behavior change is
intended.
- **`create-notebook` contract imports the data-layer
`notebook-schema`.** This matches `update-notebook`. It should be moved
behind the contract before the planned ESLint rule step, which restricts
contract modules from importing data-layer code.

## Testing

- `vitest` for `lib/ai`, `components/ui/AIAssistantPanel`, and `state`:
920 tests pass across 71 files.
- `tsc`: one error remains in `packages/ui-patterns`
(`InstructionBlocks.tsx`), which is unrelated to this change. I have not
verified whether it also fails on the base branch.
- ESLint reports no errors on the changed files (9 `no-explicit-any`
warnings in `tool-filter.ts` and its test); Prettier is clean.
- Not run: knip and the lint ratchet.

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.
