Rebuild browser automation binary

cd .claude/skills/gstack rm -rf browse/dist ./setup Permission Errors

Fix executable permissions

cd .claude/skills/gstack chmod +x setup browse/dist/browse Missing Dependencies

Reinstall Node dependencies

cd .claude/skills/gstack rm -rf node_modules bun install Browser Automation Failures // Debug browser issues You : / browse -- debug // Runs browser in non-headless mode for inspection // Clear browser data rm - rf . gstack / browser - data Skill Registration Issues // Re-register skills cd . claude / skills / gstack . / setup // Verify skills are available You : / plan - ceo - review -- help The skills work by providing specialized prompts and browser automation tools that transform Claude Code into domain experts. Each workflow enforces specific cognitive modes - CEO strategic thinking, engineering rigor, paranoid review, or systematic testing - instead of generic assistance.
