Charis 4dee589735 fix(studio): stop assistant fabricating database_identifier for notebooks (#49558)
## Summary

* Fixes
[FE-4275](https://linear.app/supabase/issue/FE-4275/assistant-always-creates-notebooks-with-wrong-identifier-first-try):
the assistant always created database notebook cells with a fabricated
`database_identifier` (`"primary"`, later observed as `""` /
`"_primary"` under different prompt wording) instead of omitting the key
for the project's primary database, which tripped the tool's
reject-and-retry validation on the very first attempt.
* Prompt wording alone wasn't reliable — live eval runs against the real
model kept substituting a new placeholder every time the prompt was
tightened further.
* Normalizes an empty-string `database_identifier` to absent at the
schema level (`databaseIdentifierSchema` in `notebook-schema.ts`), which
is inherited by every schema built from it — the AI SDK's `inputSchema`
for `create_notebook`/`update_notebook`, and the write-boundary
`writableNotebookSchema` used right before the PUT to the backend.
* Adds an eval case (`evals/dataset.ts`) reproducing the original bug,
plus unit tests covering schema-level and write-boundary normalization.

## Test plan

- [X] `pnpm --filter studio exec tsc --noEmit` passes
- [X] `pnpm exec prettier --check` passes on touched files
- [X] Unit tests pass: `notebook-schema.test.ts`,
`notebook-upsert-mutation.test.ts`, `notebook-tools.test.ts` (104 tests)
- [X] Ran the new eval case against the real model 3x before the code
fix (0% correctness, fabricated `""`/`"_primary"`) and 3x after (100%
correctness)

## Summary by CodeRabbit

* **Bug Fixes**
* Improved notebook handling of empty database identifiers by treating
them as absent.
  * Ensured notebook requests omit unused database identifier fields.
  * Added validation guidance for read-replica database identifiers.

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
