## Summary Each assistant tool's identity and contract is currently written in up to nine places that nothing ties together at compile time. This PR adds a contract/server split and migrates `update_notebook`, the tool with the most copies, as the first proof of the design. - **Contract** (`lib/ai/tools/update-notebook.ts`): isomorphic file with the input and output schemas, approval flag, minimum opt-in level, and `toModelOutput`, the single rule for what the model may see. - **Server** (`update-notebook.server.ts`): the executable tool, built with `approvalGatedToolFromContract`. - **Registry** (`registry.ts`): collects contracts, derives a typed `StudioUIMessage`, and provides `sanitizeContractPart` for history replay. - **Shared types** (`types.ts`): `ToolContract`, `ToolContext`, `ToolFactory`, plus a single `getAuthHeaders` replacing three variants. - **Approval gate** (`approval-gate.ts`): approval-gated tools get `acceptUntrustedSql` / `acceptUntrustedLogsSql` through a gate passed to `execute`, and `*.server.ts` files can't import the raw functions (ESLint). - **Opt-in level**: `update_notebook` is gated by its contract's `minOptInLevel`. `TOOL_CATEGORY_MAP` is now typed against `ToolName` and excludes migrated tools, which exposed `get_active_incidents` missing from the name enum. Removed duplicates: the `update_notebook` sanitizer in `tool-sanitizer.ts`, the client-side `stripNotebookSnapshot`, and the copied update schemas in `Message.utils.ts`. ## Behavior changes - The client no longer strips `previous_content` from `update_notebook` outputs before sending history, so requests carry the previous notebook snapshot. The server still strips it before the model sees it. - On history replay, an `update_notebook` output that doesn't match its schema is dropped instead of passed through minus `previous_content`. ## Testing - New `registry.test.ts` (typed parts, replay sanitizer) and a contract case in `tool-filter.test.ts`. - Studio typecheck, lint ratchet, knip, Prettier and the affected vitest suites pass.
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
masterand 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.
- Type:
- 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 pullfrequently 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
infrastructurerepo.
# 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=
