Skill Creator

If you've ever copy-pasted skill templates and manually filled in YAML frontmatter, this automates the whole thing. It walks you through a five-phase workflow: brainstorming what your skill should do, optionally refining prompts with the prompt-engineer skill, generating all the boilerplate files with proper directory structures, validating against Anthropic standards, and installing either locally or globally. The progress tracking is thoughtful with visual gauges at each step, and it handles multi-platform setup for Copilot, Claude, and Codex simultaneously. Nice for teams standardizing on skill creation patterns, though the real test is whether the generated skills actually need less manual tweaking afterward. Worth trying if you're building more than two or three skills.
