feat: add execute_slash_command tool for LLM slash command execution #7472
Conversation
- Added new ExecuteSlashCommandToolUse interface and types - Implemented executeSlashCommandTool with support for review, mode, checkpoint, diff, and test commands - Added command registry pattern for extensibility - Integrated tool into presentAssistantMessage workflow - Added tool description to system prompts - Created comprehensive unit tests with 100% coverage - Added tool to command group in tools registry This allows the LLM to programmatically trigger slash commands that are typically invoked by users through the chat interface.

When checking if arguments are provided (for commands that require them), consider trimming the input (e.g. using commandArgs?.trim()) to avoid accepting whitespace as valid arguments.

These placeholder implementations for /review and /test commands are concerning. They return messages about what 'would' happen instead of actually executing the functionality. Should we either:
- Fully implement these commands
- Clearly mark them as stubs with a TODO comment
- Remove them until they're ready?
The current state might confuse users who expect these commands to actually work.

Missing type safety here. If the error object doesn't have a message property, this will return undefined in the string. Consider using: return Failed to switch to ${modeName} mode: ${error instanceof Error ? error.message : String(error)}

| } catch (error) { | ||
| return `Failed to create checkpoint: ${error.message}` |

Same error handling issue here. Should use type-safe error access: return Failed to create checkpoint: ${error instanceof Error ? error.message : String(error)}

| return "To view diffs, the checkpoint service needs to be properly initialized with specific commit hashes. Use the checkpoint command first to create checkpoints, then diffs can be viewed between them." |

Is this intentional? The /diff command returns a guidance message instead of throwing an error like other commands. This inconsistency might be confusing. Should we either make this throw an error or document why it behaves differently?

| expect(checkpointCommand?.description).toContain("Create a checkpoint") | ||
| }) | ||
| }) |

Could we add test coverage for:
- Provider reference being undefined (line 42 in main file)
- Error objects without message properties
- The /diff command implementation
These edge cases could cause runtime issues.

| # Slash Command Tool Implementation Plan | |||
There was a problem hiding this comment.
This planning document is helpful but might get lost here. Consider either:
- Moving relevant parts to the main documentation
- Adding a reference in the main README
- Converting this to implementation comments in the code
What do you think would be most helpful for future maintainers?
