+# Agent Development Guide for TaskSquire
+
+This guide is for AI coding agents working on TaskSquire, a Go-based TUI (Terminal User Interface) for Taskwarrior.
+
+## Project Overview
+
+- **Language**: Go 1.22.2
+- **Architecture**: Model-View-Update (MVU) pattern using Bubble Tea framework
+- **Module**: `tasksquire`
+- **Main Dependencies**: Bubble Tea, Lip Gloss, Huh, Bubbles (Charm ecosystem)
+
+## Build, Test, and Lint Commands
+
+### Building and Running
+```bash
+# Run directly
+go run main.go
+
+# Build binary
+go build -o tasksquire main.go
+
+# Run tests
+go test ./...
+
+# Run tests for a specific package
+go test ./taskwarrior
+
+# Run a single test
+go test ./taskwarrior -run TestTaskSquire_GetContext
+
+# Run tests with verbose output
+go test -v ./taskwarrior
+
+# Run tests with coverage
+go test -cover ./...
+```
+
+### Linting and Formatting
+```bash
+# Format code (always run before committing)
+go fmt ./...
+
+# Lint with golangci-lint (available via nix-shell)
+golangci-lint run
+
+# Vet code for suspicious constructs
+go vet ./...
+
+# Tidy dependencies
+go mod tidy
+```
+
+### Development Environment
+```bash
+# Enter Nix development shell (provides all tools)
+nix develop
+
+# Or use direnv (automatically loads .envrc)
+direnv allow
+```
+
+## Project Structure

+```
+
+## Code Style Guidelines
+
+### Imports
+- **Standard Library First**: Group standard library imports, then third-party, then local
+- **Local Import Pattern**: Use `tasksquire/<package>` for internal imports
+```go
+import (
+    "context"
+    "fmt"
+    "log/slog"
+    
+    tea "github.com/charmbracelet/bubbletea"
+    "github.com/charmbracelet/lipgloss"
+    
+    "tasksquire/common"
+    "tasksquire/taskwarrior"
+)
+```
+
+### Naming Conventions
+- **Exported Types**: PascalCase (e.g., `TaskSquire`, `ReportPage`, `Common`)
+- **Unexported Fields**: camelCase (e.g., `configLocation`, `activeReport`, `pageStack`)
+- **Interfaces**: Follow Go convention, often ending in 'er' (e.g., `TaskWarrior`, `TimeWarrior`, `Component`)
+- **Constants**: PascalCase or SCREAMING_SNAKE_CASE for exported constants
+- **Test Functions**: `TestFunctionName` or `TestType_Method`
+
+### Types and Interfaces
+- **Interface-Based Design**: Use interfaces for main abstractions (see `TaskWarrior`, `TimeWarrior`, `Component`)
+- **Struct Composition**: Embed common state (e.g., pages embed or reference `*common.Common`)
+- **Pointer Receivers**: Use pointer receivers for methods that modify state or for consistency
+- **Generic Types**: Use generics where appropriate (e.g., `Stack[T]` in `common/stack.go`)
+
+### Error Handling
+- **Logging Over Panicking**: Use `log/slog` for structured logging, typically continue execution
+- **Error Returns**: Return errors from functions, don't log and return
+- **Context**: Errors are often logged with `slog.Error()` or `slog.Warn()` and execution continues
+```go
+// Typical pattern
+if err != nil {
+    slog.Error("Failed to get tasks", "error", err)
+    return nil // or continue with default behavior
+}
+```
+
+### Concurrency and Thread Safety
+- **Mutex Protection**: Use `sync.Mutex` to protect shared state (see `TaskSquire.mu`)
+- **Lock Pattern**: Lock before operations, defer unlock
+```go
+ts.mu.Lock()
+defer ts.mu.Unlock()
+```
+
+### Configuration and Environment
+- **Environment Variables**: Respect `TASKRC` and `TIMEWARRIORDB`
+- **Fallback Paths**: Check standard locations (`~/.taskrc`, `~/.config/task/taskrc`)
+- **Config Parsing**: Parse Taskwarrior config format manually (see `taskwarrior/config.go`)
+
+### MVU Pattern (Bubble Tea)
+- **Components Implement**: `Init() tea.Cmd`, `Update(tea.Msg) (tea.Model, tea.Cmd)`, `View() string`
+- **Custom Messages**: Define custom message types for inter-component communication
+- **Cmd Chaining**: Return commands from Init/Update to trigger async operations
+```go
+type MyMsg struct {
+    data string
+}
+
+func (m Model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
+    switch msg := msg.(type) {
+    case MyMsg:
+        // Handle custom message
+        return m, nil
+    }
+    return m, nil
+}
+```
+
+### Styling with Lip Gloss
+- **Centralized Styles**: Define styles in `common/styles.go`
+- **Theme Colors**: Parse colors from Taskwarrior config
+- **Reusable Styles**: Create style functions, not inline styles
+
+### Testing
+- **Table-Driven Tests**: Use struct slices for test cases
+- **Test Setup**: Create helper functions like `TaskWarriorTestSetup()`
+- **Temp Directories**: Use `t.TempDir()` for isolated test environments
+- **Prep Functions**: Include `prep func()` in test cases for setup
+
+### Documentation
+- **TODO Comments**: Mark future improvements with `// TODO: description`
+- **Package Comments**: Document package purpose at the top of main files
+- **Exported Functions**: Document exported functions, types, and methods
+
+## Common Patterns
+
+### Page Navigation
+- Pages pushed onto stack via `common.PushPage()`
+- Pop pages with `common.PopPage()`
+- Check for subpages with `common.HasSubpages()`
+
+### Task Operations
+```go
+// Get tasks for a report
+tasks := ts.GetTasks(report, "filter", "args")
+
+// Import/create task
+ts.ImportTask(&task)
+
+// Mark task done
+ts.SetTaskDone(&task)
+
+// Start/stop task
+ts.StartTask(&task)
+ts.StopTask(&task)
+```
+
+### JSON Handling
+- Custom Marshal/Unmarshal for Task struct to handle UDAs (User Defined Attributes)
+- Use `json.RawMessage` for flexible field handling
+
+## Key Files to Reference
+
+- `common/component.go` - Component interface definition
+- `common/common.go` - Shared state container
+- `taskwarrior/taskwarrior.go` - TaskWarrior interface and implementation
+- `pages/main.go` - Main page router pattern
+- `taskwarrior/models.go` - Data model examples
+
+## Development Notes
+
+- **Logging**: Application logs to `app.log` in current directory
+- **Virtual Tags**: Filter out Taskwarrior virtual tags (see `virtualTags` map)
+- **Color Parsing**: Custom color parsing from Taskwarrior config format
+- **Debugging**: VSCode launch.json configured for remote debugging on port 43000
