Summary of Changes

Hello @kevinthecheung, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the mcp command-line interface by adding a new option, --generate-prompt-list. This option allows users to output a markdown-formatted table detailing all available prompts, their feature groups, descriptions, and arguments. This change mirrors the existing functionality for generating tool lists, improving the discoverability and documentation of mcp's prompt system.

Highlights

• New CLI Option: Introduced --generate-prompt-list to the mcp command, enabling the generation of a markdown list of available prompts.
• Prompt Documentation Generation: Added a new function markdownDocsOfPrompts in src/mcp/prompts/index.ts responsible for compiling prompt details into a formatted markdown table.
• Unified Early Exit Logic: Refactored the mcp command's startup logic to gracefully handle and exit after generating either tool or prompt lists, preventing further execution.

Code Review

This pull request adds a --generate-prompt-list option to generate documentation for available prompts. My review found a critical issue in the implementation where not all prompts would be included in the generated output. I've also provided suggestions to improve the code's readability and maintainability by removing redundant logic and adopting more modern, idiomatic TypeScript for string construction. The changes to the command-line argument parsing are sound.
