Slackoscope

Slack messages in your code editor, hover or inline or inserted as comments, for those with no short term memory and a dislike for alt-tabbing.

𒂷 Now with Linear 𒀱 shoehorned in! 𒉓

What it does

• Hover a Slack message URL to view the message, thread, and files
• Show inline previews next to URLs (toggle on/off)
• Insert a message as a language-appropriate comment
• Optional: post the current file to a Linear issue referenced in the thread (“Post to Linear”)

Linear (optional)

It was kinda purpose built for lazy ass tech-support work, so I got Linear integration in here. It works by spotting the Linear Asks msg and pulling the ticket ref from it. Your milage may vary, but feel free to dig in (The detection lives in src/linear/detector.ts - look for extractLinearIssueFromMessage) and PR if this can help your day-to-day trudgery.
