Superset Monorepo Guide

You're running inside a Superset workspace — an isolated git-worktree copy of this repo. "Workspace" in any user message refers to this, not VS Code/editor workspaces.

Question Tool

When you need to ask the user ANY question — including simple yes/no, confirmations, and clarifications — ALWAYS use the ask_user tool. Never ask questions in plain text. The Superset UI renders ask_user calls as an interactive overlay with clickable option buttons; plain-text questions will not be surfaced to the user in the same way.

Guidelines for agents and developers working in this repository.

Structure

Bun + Turbo monorepo: apps/ (web, marketing, admin, api, desktop, docs, mobile) and packages/ — see ls apps/ packages/ for the full list.

• Add shadcn components: npx shadcn@latest add <component> (run in packages/ui/)

Tech Stack

• Package Manager: Bun (no npm/yarn/pnpm)
• Next.js: Version 16 - NEVER create middleware.ts. Next.js 16 renamed middleware to proxy.ts. Always use proxy.ts for request interception.

Common Commands

Standard scripts live in the root package.json (bun dev, bun test, bun run lint:fix, bun run typecheck, ...).

# Releases (desktop + host-service + cli share one version; see scripts/release/README.md)
bun run release            # interactive: desktop release or CLI hotfix
bun run release desktop    # desktop app release (draft by default)
bun run release cli        # interim CLI hotfix (<desktop>-N prerelease)
bun run check:versions     # assert versions are unified

Cut releases on a dedicated release branch (not main); bun run release desktop <version> <commit> provisions one from a commit. Full runbook: scripts/release/README.md.

Code Quality

Biome runs at root level (not per-package) for speed — use bun run lint:fix to fix all issues automatically.

Agent Rules

1. Type safety - avoid any unless necessary

2. Prefer gh CLI - when performing git operations (PRs, issues, checkout, etc.), prefer the GitHub CLI (gh) over raw git commands where possible

3. Shared command and skill source - keep command definitions in .agents/commands/ and skill definitions in .agents/skills/. .claude/commands and .cursor/commands should be symlinks to ../.agents/commands; .claude/skills should be a symlink to ../.agents/skills. (packages/chat discovers slash commands from .claude/commands.) Skills aren't a cross-agent format yet, so non-Claude agents (Codex, Cursor, OpenCode) should read the relevant .agents/skills/*/SKILL.md file directly when its description matches the task.

4. Workspace MCP config - keep shared MCP servers in .mcp.json; .cursor/mcp.json should link to ../.mcp.json. Codex uses .codex/config.toml (run with CODEX_HOME=.codex codex ...). OpenCode uses opencode.json and should mirror the same MCP set using OpenCode's remote/local schema.

   Mistral Vibe compatibility: Vibe reads AGENTS.md + .agents/skills/ natively (trust granted via --trust; no .agents/commands support). Configure it via .vibe/config.toml; it consumes MCP servers as [[mcp_servers]] TOML entries (not .mcp.json).

5. Mastra dependencies - use the published upstream mastracode and @mastra/* packages. Do not add fork tarball overrides or custom patch steps unless explicitly requested.

6. Plan & doc placement - implementation plans go in plans/ (cross-cutting) or apps/<app>/plans/ (app-scoped); shipped plans move to plans/done/. Architecture/reference docs go in <app>/docs/. Never drop *_PLAN.md at an app root or inside src/.

7. Always fix lint warnings before pushing - CI fails on Biome warnings, not just errors (the lint script treats warnings as errors). Run bun run lint:fix after edits and verify bun run lint exits 0 before git push. Never push code that produces lint output, even auto-fixable formatting.

8. Linear ticket format - all tickets (creation, drafting, grooming) follow .agents/skills/ticket-format/SKILL.md. Read that file before creating or grooming a ticket.

9. TanStack DB / Electric live queries are cache-first - useLiveQuery can return persisted rows in data while the collection is still not isReady. Always render existing rows first. Use isReady only to decide what to show when no row/data exists yet: no data + not ready = loading/skeleton/null; no data + ready = empty/not-found. Never hide, blank, or replace existing data just because isReady is false or isLoading is true. This cache-first rendering rule does not apply to write/seeding side effects: wait for strict readiness before deriving missing rows or writing defaults, unless the write is provably idempotent.

10. PR titles are conventional commits - PRs are squash-merged using the PR title as the commit subject, so every title needs a conventional-commit type and scope, e.g. feat(desktop): add copy-logs button to failed CI checks or fix(host-service): guard against missing PR.

11. Mobile is iOS-only for the time being - apps/mobile targets iOS only. Don't add Android fallbacks or platform guards for iOS-only APIs (e.g. @expo/ui/swift-ui), and don't treat Android incompatibility as a blocker until Android is explicitly put in scope.

└── Header/

1. One folder per component: ComponentName/ComponentName.tsx + index.ts for barrel export
2. Co-locate by usage: If used once, nest under parent's components/. If used 2+ times, promote to highest shared parent's components/ (or components/ as last resort)
3. One component per file: No multi-component files
4. Co-locate dependencies: Utils, hooks, constants, config, tests, stories live next to the file using them

Exception: shadcn/ui Components

The src/components/ui/ and src/components/ai-elements directories contain shadcn/ui components. These use kebab-case single files (e.g., button.tsx, base-node.tsx) instead of the folder structure above. This is intentional—shadcn CLI expects this format for updates via bunx shadcn@latest add.

Database Rules

** IMPORTANT ** - Never touch the production database unless explicitly asked to. Even then, confirm with the user first.

• Schema in packages/db/src/
• Use Drizzle ORM for all database operations

DB migrations

• Never run a migration yourself, and NEVER manually edit files in packages/db/drizzle/ (.sql files, meta/_journal.json, snapshots — all auto-generated). Only modify schema files in packages/db/src/schema/ and ask the user to run drizzle-kit generate.
• Workflow (Neon branch setup, drizzle-kit invocation): see .agents/skills/db-migrations/SKILL.md.
