+# websimple-stack
+
+Use this skill for host environment, Docker Compose, Traefik routing, and shared tooling concerns surrounding the Websimple local development environment.
+
+The Websimple local development Docker stack is maintained in Gitea:
+
+- https://gitea.websimple.com/docker/websimple-stack
+
+## Config values used here
+
+These environment variables drive stack-level operations:
+
+- `WEBSIMPLE_STACK_PATH`: local path to the `websimple-stack` Docker project checkout.
+- `WEBSIMPLE_STACK_PROTOCOL`: protocol used by local Traefik routing, `http` or `https`.
+- `WEBSIMPLE_STACK_DOMAIN`: local domain suffix used by Traefik labels.
+
+Do not hard-code these values in commands or examples. Read them from the environment. If any are missing when needed, ask the user to export them before proceeding rather than guessing.
+
+## Environment expectations
+
+The plugin assumes it is running on a developer machine configured for the Websimple local development stack.
+
+### Stack and routing
+
+- The `websimple-stack` Docker Compose project is configured and running locally.
+- A wildcard `*.${WEBSIMPLE_STACK_DOMAIN}` resolves to the local IP.
+- Traefik serves local stack services at `${WEBSIMPLE_STACK_PROTOCOL}://*.${WEBSIMPLE_STACK_DOMAIN}` using that wildcard domain routing.
+
+### Required host executables
+
+The following executables are expected to be available in the host `$PATH`:
+
+- `mysql`
+- `node`
+- `pnpm`
+- `php`
+- `composer`
+- `wp`
+
+### MySQL access
+
+- MySQL credentials are stored in `~/.my.cnf`.
+- The `mysql` client should connect without prompting for a password.
+- `/etc/hosts` contains an entry resolving `mysql`, so the DB host resolves the same way on the host as it does inside containers.
+
+### WP-CLI defaults
+
+- WP-CLI defaults are configured in `~/.wp-cli/config.yml`.
+- DB host, user, and password defaults are already set there.
+- `wp core config` workflows should only need to specify the database name.
