feat: add optional mode field to slash command front matter

[roomote]

Add an optional "mode" field to slash command front matter that will automatically switch to the specified mode if it exists when the command is executed.

Changes Made

• Added optional mode field to the Command interface in src/services/command/commands.ts
• Updated command parsing logic in both tryLoadCommand and scanCommandDirectory functions to extract mode from frontmatter
• Modified RunSlashCommandTool to automatically switch mode when a mode is specified in the command
• Added comprehensive tests for mode field parsing in frontmatter-commands.spec.ts
• Added tests for mode switching functionality in runSlashCommandTool.spec.ts
• Updated existing test cases to include the new mode field

Usage Example

Create a slash command with the mode field in frontmatter:

---
description: Debug the application
mode: debug
---

# Debug Command

Start debugging the application with proper breakpoints.

When this command is executed via run_slash_command, it will automatically switch to debug mode before presenting the command content.

Testing

All tests are passing:

• ✅ Frontmatter parsing tests (16 tests passed)
• ✅ RunSlashCommandTool tests (13 tests passed)

Important

Add optional mode field to slash command front matter for automatic mode switching in commands.ts and RunSlashCommandTool.ts, with updated tests.

• Behavior:
  • Add optional mode field to Command interface in commands.ts.
  • Update tryLoadCommand and scanCommandDirectory in commands.ts to parse mode from frontmatter.
  • Modify RunSlashCommandTool in RunSlashCommandTool.ts to switch mode if specified.
• Testing:
  • Add tests for mode field parsing in frontmatter-commands.spec.ts.
  • Add tests for mode switching in runSlashCommandTool.spec.ts.
  • Update existing tests to include mode field.

Review complete. No issues found.

The implementation cleanly adds an optional mode field to slash command frontmatter that automatically switches to the specified mode when a command is executed. Key observations:

• Mode parsing follows consistent patterns with existing frontmatter fields
• Mode validation uses getModeBySlug to check existence before switching
• Graceful degradation when mode doesn't exist (command still executes)
• Comprehensive test coverage for both tool-based and manual slash commands
• All existing tests updated to handle the new return type

• Return type changes to ParseMentionsResult and ProcessUserContentMentionsResult properly handled at all call sites
• Comprehensive test coverage for both tool-based (RunSlashCommandTool) and manual slash commands (parseMentions)
• All existing tests updated to handle the new return type structure
