[anchapin]

Phase: Phase 1 - Foundation
Priority: medium
Component: orchestrator
Effort: small

Description

Implement config file parsing (TOML format) for user settings. Support: MCP server configs, logging preferences, VM settings. Use serde for deserialization.

Acceptance Criteria

• Add serde and toml dependencies to Cargo.toml
• Define configuration structs
• Implement TOML config file parsing
• Support MCP server configurations
• Support logging preferences (log level, format)
• Support VM settings (pool size, memory, CPU)
• Add default configuration
• Add config validation
• Add tests for config parsing

Dependencies

• None

Notes

Configuration should follow XDG config directory standards on Linux/Mac. Use ~/.config/luminaguard/config.toml as the default location.
