Claude Spec-Kit Linux Setup

I need my local Linux workstation ready to run the GitHub spec-kit repository inside Claude Code, updated to the brand-new Opus 5.5 model, and I need it done live with me at 12:00 Ankara time today (GMT +3). Please study the repo and any Anthropic integration guides beforehand so our session is smooth. We will connect by screenshare at noon; you will handle every command while I follow along. Key deliverables during that call: • Clone and build spec-kit from https://github.com/github/spec-kit . all work done in screenshare, i will drive. Do your homework to make sure it takes max advantage of opus 5.5. this is 1hr setup plus 1-2 hrs per week support
