05-code-style-and-structure.mdc — Python + TS rules, error/logging security
07-project-conventions.mdc — auth, config, permissions store, breadcrumbs
08-testing-and-deployment.mdc — local dev, log paths, ports, Playwright MCP
09-package-management.mdc — yarn (not npm)

11-database-migrations.mdc — Alembic short-revision convention, single-head rule, new-migration workflow

Claude-specific

This repo intentionally does not ship project-level subagents or slash commands. Use Claude Code's built-in subagent types (e.g., backend-architect, code-reviewer, frontend-developer, test-engineer) and built-in PR/commit flows.
MCP servers typically configured in this workspace: Databricks, Playwright, Shadcn UI, Ref, magicui, sequential-thinking, context7, memory. Prefer them over ad-hoc shell commands when applicable.

NEVER restart the dev server processes. Backend and frontend run with auto-reload. See 08-testing-and-deployment.mdc.
Backend logs: /tmp/backend.log. Frontend logs: /tmp/frontend.log. Read them for debugging.
Backend port: 8000. Frontend port: 3000.
Run Python via hatch -e dev run ....
Frontend package manager is yarn, not npm.
