+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Build and Development Commands
+
+```bash
+# Build the project
+go build -o redmine
+
+# Install dependencies and clean up
+go mod tidy
+
+# Test the built binary
+./redmine --help
+
+# Run all tests (currently no tests exist)
+go test -v ./...
+```
+
+## Project Architecture
+
+This is a Redmine CLI tool written in Go using the Cobra framework. The application follows a standard CLI architecture with clear separation of concerns:
+
+### Core Components
+
+- **main.go**: Entry point that delegates to cmd.Execute()
+- **cmd/**: Contains all CLI command definitions using Cobra framework
+  - **root.go**: Root command setup with global profile flag
+  - **issues.go**: Issue management commands (list, show)
+  - **profile.go**: Profile management commands (add, list, use, remove, show)
+  - **auth.go**: Authentication commands (legacy, prefer profile commands)
+- **config/**: Configuration management with YAML persistence
+  - **config.go**: Profile-based configuration with ~/.redminecli/config storage
+- **client/**: Redmine API client with HTTP communication
+  - **client.go**: HTTP client with complete Redmine API models (Issue, Project, User, etc.)
+
+### Configuration System
+
+The application uses a profile-based configuration system:
+- Configuration stored in `~/.redminecli/config` as YAML
+- Each profile contains: name, Redmine URL, and API key
+- Supports default profile and per-command profile override via `--profile` flag
+- Profile management through `profile` commands (add, remove, use, list, show)
+
+### API Client Architecture
+
+The HTTP client (`client/client.go`) provides:
+- Structured Redmine API models (Issue, Journal, Project, User, etc.)
+- Authentication via X-Redmine-API-Key header
+- JSON response parsing with proper error handling
+- Support for pagination and filtering parameters
+- Include parameters for fetching related data (e.g., journals for comments)
+
+### Command Structure
+
+Commands follow a hierarchical structure:
+- `redmine issues list` - List issues with filtering options
+- `redmine issues show <id>` - Show issue details with optional comments
+- `redmine profile add/list/use/remove/show` - Profile management
+- Global `--profile` flag for per-command profile selection
+
+### Dependencies
+
+- **github.com/spf13/cobra**: CLI framework for command structure
+- **gopkg.in/yaml.v3**: YAML configuration file handling
+- Standard library for HTTP client and JSON processing
+- Uses mise.toml for Go version management (latest)
+
+### Development Notes
+
+- No test suite currently exists
+- Binary excluded from git via .gitignore (redmine, redmine-*)
+- Configuration files (.yaml/.yml) excluded from git for security
+- API keys are masked in profile display output
+- 30-second HTTP timeout for API requests
