metabase

Write or modify TypeScript and JavaScript code, including tests and test helpers, following Metabase coding standards. Use before editing any TS/TSX/JS/JSX file.

Where Metabase backend code goes and how it reaches the app DB. Covers module layout, the `<module>.db` rule, `[:auto/param]` value binding, module config, and pre-handoff checks. Use when adding or moving backend namespaces, writing app-DB queries, or…

Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports from components.

Review TypeScript and JavaScript code changes for compliance with Metabase coding standards, style violations, and code quality issues. Use when reviewing pull requests or diffs containing TypeScript/JavaScript code.

Deciding where frontend code lives — tier model, move mechanics, extension points, side effects, naming, and the traps. Use when moving code between modules, carving new modules, fixing boundary violations, adding a barrel or an endpoint, or reviewing…

Update or build a Metabase design-system component (frontend/src/metabase/ui — Chip, Badge, Alert, Switch, etc.) to match a Figma spec described in a Linear issue. Use when a ticket asks to restyle an existing `metabase/ui` component or implement a new one…

Draft or audit the REST API changelog (docs/developers-guide/api-changelog.md) by semantically diffing the checked-in OpenAPI spec between two git refs. Use when asked "has the API changelog been updated", "what are the breaking API changes in vNN", when…

Suggest a space-themed name for a cyclic cluster of backend modules when metabase.core.module-cycles-test reports a cluster without a name, usually after a split. Use when someone needs to name a module cycle or add a line to…

Foundations for driving Metabase from the terminal with the `mb` CLI — authentication and named profiles, the flag/output/`--json` conventions every command shares, JSON body input, command discovery via `--help` (add `--json` for machine-readable schemas),…

Author and debug MBQL query bodies for the `mb` CLI — the query shape, clauses, filters, aggregation and breakout, order and limit, expressions, joins and FK columns, multi-stage pipelines, saved questions and definitions as sources, output column names, and…

Author native SQL queries with parameters (filter widgets) for the `mb` CLI. Native SQL is a query whose single stage is raw SQL (`mbql.stage/native`) instead of structured MBQL — the same query envelope, so it is pre-flight-validated and round-trips. Covers…

Build Metabase dashboards via the `mb` CLI — lay out dashcards on the 24-column grid (`{col,row,size_x,size_y}` math, per-chart default sizes) and turn cards into a filterable, cross-linked app. Covers wiring filters to cards (parameters +…

Author and run Metabase transforms via `mb` — body shape (native SQL or structured MBQL), create + run-with-wait, run inspection, dependencies, cancel, the `update`-vs-recreate iteration rule, the writable-keys-only PATCH contract, plus transform tags and…

Choose a card's `display` (chart type) and author its `visualization_settings` for the `mb` CLI — which chart fits which data shape, the required keys per chart, the rule that settings name OUTPUT columns, and the `column_settings` JSON-string-key footgun;…

Drive a Metabase instance from the terminal via the `mb` CLI — auth, databases, cards, dashboards, transforms, queries, search, git-sync. Discovery entry; load the full guide with `mb skills get core`.

Add a Metabase API resource end-to-end — Zod schema in `packages/client/src/domain/`, methods in `packages/client/src/resources/`, list/get commands in `packages/cli/src/commands/<noun>/`, unit tests where logic warrants them, and a comprehensive e2e suite.…

Understands the Metabase Representation Format — a YAML-based serialization format for Metabase content (collections, cards, dashboards, documents, segments, measures, snippets, transforms, actions, and data apps' resources). Use when the user needs to…

Drive a Metabase instance from the terminal via the `mb` CLI: auth profiles, databases and schemas, schema sync and field-values rescan, tables, fields, cards (questions, models, metrics) run as JSON/CSV/XLSX, dashboards and dashcards, collections and their…

Build or change a Metabase data app on an rde machine: settles what the `metabase-data-app-*` skills need from the local setup (the remote-sync repository, the Metabase URL, the API key rde stores, how the app reaches Metabase), makes sure everything the app…

Expert data engineering with Metabase at the center of any company's stack: explore and profile raw warehouse tables, build clean tables as Metabase transforms pinned by transform tests, build the semantic layer (models, metrics, measures, segments,…

A Metabase AI-governance coach, covering the *controls and rollout* side of AI: who may use Metabot, what it can see, what it costs, where the model runs, and the audit trail. Use this skill whenever the user wants to roll out AI analytics safely, control who…

A Metabase AI-readiness coach, covering the *data groundwork* that makes AI answers trustworthy: modeling with Transforms, table and field metadata, the Glossary, saved Metrics, and marking canonical content. Use this skill whenever the user wants to check if…

A spaced repetition learning coach for Metabase. Use this skill whenever the user wants to: learn Metabase, start a Metabase training session, do a Metabase review, practice Metabase concepts, check what they should study today, get quizzed on Metabase, run…

Understands the Metabase Database Metadata Format — a YAML-based on-disk representation of databases, tables, and fields synced from a Metabase instance. Use when the user needs to read, edit, or understand metadata files produced by…

Reference material for Metabase reproduction — REPL recipes, API patterns, domain quirks (pivot tables, serialization, H2 tips), edge case handling, and MCP tools table. Invoke at Phase 4 start.

Write a failing test for a reproduced Metabase bug. Invoked from the /repro workflow when status is REPRODUCED. Determines test type (Clojure/Jest/Cypress), finds the right test file, writes a minimal failing test, runs it, and saves a patch.

Set up and run a local Metabase instance. Downloads the JAR (if Java 21+ is available) or runs via Docker. Also handles stopping running instances.

Read these instructions before using Metabase MCP tools. Setup is needed to connect to Metabase instances via the built-in MCP server.
