Thread Management

Keep email conversations connected - link replies to their threads, reconstruct conversation history, and detect when threads go wrong.

When to use this skill

Building or debugging email thread reconstruction from headers
Replies are not grouping into conversations correctly
Implementing In-Reply-To and References headers on outbound replies
Stripping quoted reply content to extract new message text
Providing conversation context to AI agents or LLMs
Detecting thread hijacking or forged thread injection attacks
Threads display differently in Gmail vs Outlook and you need cross-client consistency
Managing long-lived threads that span days or weeks
Splitting or merging conversations programmatically
