There is a skill installation option. The skill markdown has 180 lines [1].
My take? I like it. It's concise enough for me to try it out. And I love the webpage.

Given that subagents have different thinking/effort behavior from the main agent and very limited control on that front (I’m not completely sure about this but see https://github.com/anthropics/claude-code/issues/14321 and I’ve also noticed very different behavior when the same prompt is used in the main agent or passed to a subagent), I’m not sure this skill will be the same.
Nice! You found the no-code option that just has the outer agent perform the duties of the workflows that cook describes. It's a bit experimental (the whole thing is really), but it would be nice to get some folks impressions of whether this works well as a pure skill or if y'all find the deterministic nature of the cook script improves reliability.
