-# ERP System Agent Guidelines
-
-This document provides instructions for coding agents working on the ERP System repository.
-
-## 1. Build, Lint, and Test
-
-### Build
-To build the application:
-```bash
-go build -o erp_system main.go
-```
-To run the application locally:
-```bash
-go run main.go
-```
-The server defaults to port `1337`.
-
-### Test
-Run all tests:
-```bash
-go test ./...
-```
-Run a specific test package:
-```bash
-go test ./internal/handlers/...
-```
-Run a single specific test function:
-```bash
-# Pattern: go test -v <package_path> -run <TestNameRegex>
-go test -v ./internal/handlers -run TestLoginSubmit
-```
-
-### Lint / Verify
-Run standard Go vetting:
-```bash
-go vet ./...
-```
-Format code (always run before committing):
-```bash
-go fmt ./...
-```
-
-## 2. Code Style & Conventions
-
-### General
-- **Language:** Go 1.25.6+
-- **Formatting:** Strictly adhere to `gofmt` standards.
-- **Naming:** 
-  - Use `PascalCase` for exported structs, fields, and functions.
-  - Use `camelCase` for unexported (private) identifiers.
-  - Keep variable names short but descriptive (e.g., `req` vs `r` is fine if context is clear, but `userRequest` is better for complex scopes).
-
-### Project Structure
-- `main.go`: Application entry point, router setup, dependency injection.
-- `internal/`: Private application code.
-  - `database/`: DB initialization and helpers.
-  - `handlers/`: HTTP handlers.
-  - `models/`: Data structs and business logic/DB queries.
-  - `middleware/`: HTTP middleware (Auth, etc.).
-- `templates/`: HTML templates (server-side rendered).
-
-### Imports
-Group imports into three blocks separated by a newline:
-1. Standard library (e.g., `"net/http"`, `"os"`)
-2. Third-party packages (e.g., `"github.com/gorilla/sessions"`)
-3. Internal project packages (e.g., `"erp_system/internal/models"`)
-
-Example:
-```go
-import (
-	"log"
-	"net/http"
-
-	"github.com/gorilla/sessions"
-
-	"erp_system/internal/models"
-)
-```
-
-### Error Handling
-- **Explicit Checks:** Always check errors. `if err != nil { ... }`.
-- **Handlers:** Use `http.Error(w, err.Error(), http.Status...)` to return errors to the client.
-- **Logging:** Log critical errors on the server side using `log.Printf` or similar before returning HTTP 500.
-
-### HTTP & Routing
-- Use Go's standard `net/http` `ServeMux` with Go 1.22+ routing patterns (e.g., `mux.Handle("GET /path/{id}", ...)`).
-- **HTMX:** The application uses HTMX.
-  - Check for `HX-Request` header to differentiate full page loads vs partials.
-  - Use `HX-Redirect` header for client-side redirection when handling HTMX requests.
-  - Render partial templates when appropriate.
-
-### Database
-- Use `internal/models` for all database interactions.
-- Pass the database connection (`*sql.DB`) or a wrapping struct to handlers via dependency injection (see `Handler` struct in `main.go`).
-
-## 3. Cursor / Copilot Rules
-(No specific Cursor or Copilot rules found in the repository yet. Adhere to the conventions above.)
