# Windmill Open-source platform for internal tools, workflows, API integrations, background jobs, and UIs. Rust backend + Svelte 5 frontend. ## Workflow 1. **Understand**: Before coding, read relevant docs from `docs/` to understand the area you're changing 2. **Plan**: For non-trivial changes, use plan mode. For large features, break into reviewable stages 3. **Execute**: Follow coding patterns from skills (`rust-backend`, `svelte-frontend`) 4. **Validate**: After every change, run the appropriate checks per `docs/validation.md` ## Documentation - **Validation**: `docs/validation.md` — what checks to run based on what you changed - **Enterprise**: `docs/enterprise.md` — EE file conventions and PR workflow - **Backend patterns**: use the `rust-backend` skill when writing Rust code - **Frontend patterns**: use the `svelte-frontend` skill when writing Svelte code - **Domain guides**: `.claude/skills/native-trigger/` and `frontend/tutorial-system-guide.mdc` - **Brand/UI guidelines**: `frontend/brand-guidelines.md` ## Dev Environment - **Backend**: `cargo run` from `backend/` (API at http://localhost:8000) - **Frontend**: `REMOTE=http://localhost:8000 npm run dev` from `frontend/` (port 3000+) - **DB**: `psql postgres://postgres:changeme@localhost:5432/windmill` - **Login**: `admin@windmill.dev` / `changeme` - **Instance settings**: navigate to `/#superadmin-settings` ## Core Principles - Search for existing code to reuse before writing new code - Follow established patterns in the codebase - Keep changes focused — don't refactor beyond what's asked
