 # Agent Guidelines for articulate-parser
 
+A Go CLI tool that parses Articulate Rise courses from URLs or local JSON files and exports them to Markdown, HTML, or DOCX formats.
+
 ## Build/Test Commands
-- **Build**: `task build` or `go build -o bin/articulate-parser main.go`
-- **Run tests**: `task test` or `go test -race -timeout 5m ./...`
-- **Run single test**: `go test -v -race -run ^TestName$ ./path/to/package`
-- **Test with coverage**: 
-  - `task test:coverage` or 
-  - `go test -race -coverprofile=coverage/coverage.out -covermode=atomic ./...`
-- **Lint**: `task lint` (runs vet, fmt check, staticcheck, golangci-lint)
-- **Format**: `task fmt` or `gofmt -s -w .`
-- **CI checks**: `task ci` (deps, lint, test with coverage, build)
+
+### Primary Commands (using Taskfile)
+
+```bash
+task build              # Build binary to bin/articulate-parser
+task test               # Run all tests with race detection
+task lint               # Run all linters (vet, fmt, staticcheck, golangci-lint)
+task fmt                # Format all Go files
+task ci                 # Full CI pipeline: deps, lint, test with coverage, build
+task qa                 # Quick QA: fmt + lint + test
+```
+
+### Direct Go Commands
+
+```bash
+# Build
+go build -o bin/articulate-parser main.go
+
+# Run all tests
+go test -race -timeout 5m ./...
+
+# Run single test by name
+go test -v -race -run ^TestMarkdownExporter_Export$ ./internal/exporters
+
+# Run tests in specific package
+go test -v -race ./internal/services
+
+# Run tests matching pattern
+go test -v -race -run "TestParser" ./...
+
+# Test with coverage
+go test -race -coverprofile=coverage/coverage.out -covermode=atomic ./...
+go tool cover -html=coverage/coverage.out -o coverage/coverage.html
+
+# Benchmarks
+go test -bench=. -benchmem ./...
+go test -bench=BenchmarkMarkdownExporter ./internal/exporters
+```
+
+### Security & Auditing
+
+```bash
+task security:check     # Run gosec security scanner
+task security:audit     # Run govulncheck for vulnerabilities
+```
 
 ## Code Style Guidelines
 
 ### Imports
+
 - Use `goimports` with local prefix: `github.com/kjanat/articulate-parser`
-- Order: stdlib, external, internal packages
-- Group related imports together
+- Order: stdlib, blank line, external packages, blank line, internal packages
+
+```go
+import (
+    "context"
+    "fmt"
+
+    "github.com/fumiama/go-docx"
+
+    "github.com/kjanat/articulate-parser/internal/interfaces"
+)
+```
 
 ### Formatting
+
 - Use `gofmt -s` (simplify) and `gofumpt` with extra rules
 - Function length: max 100 lines, 50 statements
-- Cyclomatic complexity: max 15
-- Cognitive complexity: max 20
+- Cyclomatic complexity: max 15; Cognitive complexity: max 20
 
 ### Types & Naming
+
 - Use interface-based design (see `internal/interfaces/`)
-- Export types/functions with clear godoc comments ending with period
+- Exported types/functions require godoc comments ending with period
 - Use descriptive names: `ArticulateParser`, `MarkdownExporter`
 - Receiver names: short (1-2 chars), consistent per type
 
 ### Error Handling
+
 - Always wrap errors with context: `fmt.Errorf("operation failed: %w", err)`
 - Use `%w` verb for error wrapping to preserve error chain
 - Check all error returns (enforced by `errcheck`)
 - Document error handling rationale in defer blocks when ignoring close errors
 
+```go
+// Good: Error wrapping with context
+if err := json.Unmarshal(body, &course); err != nil {
+    return nil, fmt.Errorf("failed to unmarshal JSON: %w", err)
+}
+
+// Good: Documented defer with error handling
+defer func() {
+    if err := resp.Body.Close(); err != nil {
+        p.Logger.Warn("failed to close response body", "error", err)
+    }
+}()
+```
+
 ### Comments
+
 - All exported types/functions require godoc comments
 - End sentences with periods (`godot` linter enforced)
 - Mark known issues with TODO/FIXME/HACK/BUG/XXX
 
 ### Security
-- Use `#nosec` with justification for deliberate security exceptions (G304 for CLI file paths, G306 for export file permissions)
-- Run `gosec` and `govulncheck` for security audits
+
+- Use `#nosec` with justification for deliberate security exceptions
+- G304: File paths from CLI args; G306: Export file permissions
+
+```go
+// #nosec G304 - File path provided by user via CLI argument
+data, err := os.ReadFile(filePath)
+```
 
 ### Testing
-- Enable race detection: `-race` flag
+
+- Enable race detection: `-race` flag always
 - Use table-driven tests where applicable
 - Mark test helpers with `t.Helper()`
+- Use `t.TempDir()` for temporary files
 - Benchmarks in `*_bench_test.go`, examples in `*_example_test.go`
+- Test naming: `Test<Type>_<Method>` or `Test<Function>`
+
+```go
+func TestMarkdownExporter_ProcessItemToMarkdown_AllTypes(t *testing.T) {
+    tests := []struct {
+        name, itemType, expectedText string
+    }{
+        {"text item", "text", ""},
+        {"divider item", "divider", "---"},
+    }
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            // test implementation
+        })
+    }
+}
+```
 
 ### Dependencies
-- Minimal external dependencies (currently: go-docx, golang.org/x/net, golang.org/x/text)
+
+- Minimal external dependencies (go-docx, golang.org/x/net, golang.org/x/text)
 - Run `task deps:tidy` after adding/removing dependencies
+- CGO disabled by default (`CGO_ENABLED=0`)
+
+## Project Structure
+
+```
+articulate-parser/
+  internal/
+    config/              # Configuration loading
+    exporters/           # Export implementations (markdown, html, docx)
+    interfaces/          # Core interfaces (Exporter, CourseParser, Logger)
+    models/              # Data models (Course, Lesson, Item, Media)
+    services/            # Core services (parser, html cleaner, app, logger)
+    version/             # Version information
+  main.go                # Application entry point
+```
+
+## Common Patterns
+
+### Creating a new exporter
+
+1. Implement `interfaces.Exporter` interface
+2. Add factory method to `internal/exporters/factory.go`
+3. Register format in `NewFactory()`
+4. Add tests following existing patterns
+
+### Adding configuration options
+
+1. Add field to `Config` struct in `internal/config/config.go`
+2. Load from environment variable with sensible default
+3. Document in config struct comments
