garrytan/gstack skill
89,700-star, 14,000-fork MIT skill set for Claude Code with 23 named-persona roles: CEO, Designer, Engineering Manager, QA, Security Engineer, Release Engineer, and 17 others. Drop any file into .claude/skills/ and Claude Code discovers it at session start.
What it does for you: YY can install one skill file per role and invoke any of the 23 business functions without writing a custom prompt each time. The Security Engineer and QA Engineer roles are directly useful for Axion agent code review. The CEO and Product Manager roles support framing and prioritisation work without switching tools.
In practice: Polished, practical, and immediately usable. Largest public Claude Code skill set by stars. MIT license, no vendor lock-in.
For: Claude (Axion). Skill files activate inside Claude Code sessions; headless Hermes does not auto-discover user-scope skill files.
Verdict: build now. 23 ready-made professional roles, MIT, drop-in install, largest public Claude Code skill repo. A one-afternoon adoption gives YY instant role coverage across every business function he touches. Not in YY's current enabledPlugins list: install by copying skill files to AXION/Skills/gstack and symlinking into .claude/skills/.
