## I have read the [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) file. YES ## What kind of change does this PR introduce? Feature and bug fix. ## What is the current behavior? The assistant can call `query_logs`, but it is not given the ClickHouse schema and query-writing guidance it needs. It also lacks a current UTC reference for producing the absolute timestamps required by the tool, which can lead to valid queries being run against the wrong time range and reported as returning zero rows. ## What is the new behavior? - Adds a dedicated `logs` knowledge topic backed by the shared ClickHouse schema and query guidance. - Requires the assistant to load that knowledge before using `query_logs`. - Includes the current UTC time in project context so relative requests can be converted to correct absolute tool parameters. - Covers the new knowledge flow and context with focused tests and updates the assistant eval expectation. ## How to test 1. Check out this PR and run Studio against a project that has recent logs. Generate some project activity first, such as an API request, if needed. 2. Open the AI Assistant and ask: `Show log counts by minute for the last 15 minutes and summarize any spikes.` 3. Expand the assistant's tool activity and verify it loads the `logs` knowledge topic before calling `query_logs`. 4. Inspect the `query_logs` input and verify: - `iso_timestamp_start` and `iso_timestamp_end` are absolute UTC timestamps ending in `Z`. - The timestamps cover approximately the requested 15-minute window. - The SQL uses ClickHouse syntax, includes a `LIMIT`, and does not put the time range in the SQL `WHERE` clause. 5. Verify the assistant's summary reflects the rows returned by `query_logs` instead of reporting zero rows when results are present. ## Additional context This is the bottom PR in stack #49294. The front-end visualization is added separately in #49293. Verified with 59 focused tests across assistant context, Studio/MCP tools, query display, and logs result parsing. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added AI-assisted project log querying through the `query_logs` tool. - Added logs knowledge guidance for time ranges, schema discovery, query limits, and concise result summaries. - Project context now includes the current UTC timestamp to improve relative time-range interpretation. - Improved notebook assistance with safer table verification and appropriate handling of log queries. - **Bug Fixes** - Prevented incorrect SQL timestamp filtering and enabled cross-service searches without requiring a source filter. - Added validation for supported knowledge topics. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

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.
