Bring docs/comparison.md up to date and make it more useful for people
choosing between the packs:
- agent-skills: add the three-tier eval framework as the current point of
difference, plus current tooling (Codex, Kiro, the npx skills CLI),
/build auto, and the 24-skill / 7-checklist / Definition-of-Done facts.
- Superpowers: correct to ~14 inner-loop skills, the consolidated single
task reviewer, the worst-case-executor plan standard, and its main
unmet ask (agent teams); drop the stale Gemini reference.
- Matt Pocock's skills: reframe around the grilling primitive and the
grown ~30-skill toolkit (in-progress/deprecated dirs, wayfinder,
seam-based TDD), not a "tight set".
- Add a much fuller "How to decide what to use" section after the table:
by shape of work, by what you optimize for, concrete scenarios, solo
vs team, and an honest shared-frontier note on cross-session memory.
Keeps the fair-not-flattering stance and the Om Mishra head-to-head.
Per review feedback: clarify that cherry-picking individual skills works,
but running two frameworks as active routers at once causes command-name
conflicts, competing routing, and clashing TDD philosophies. Recommend
one primary router + à la carte borrowing.
