Point it at any page. It ranks what matters.
The skill reads the page, picks the principles that actually move the needle for that page type, and ranks them by impact. Hick's Law, anchoring, loss aversion, cognitive load. You get the reasoning behind every call, not a generic checklist.
It refuses to play dirty.
Fake scarcity, confirmshaming, hidden costs, dark defaults. Eight dark patterns are documented as hard bans. The skill never suggests them, and it flags them the moment it spots them in your code. Persuasion without the manipulation.
The diff, not the lecture.
Every recommendation ships with before-and-after code you can paste straight in. Anchoring on a pricing card, the Zeigarnik effect on a multi-step flow. Engineers see exactly what changes and why, down to the markup.
Built like a developer would build it.
- Conversion Sequence Patterns
Pre-built psychology flows for newsletter signup, free-trial-to-paid, abandoned cart recovery, and more — each mapped to the exact principles that should fire at each step.
- Worked Example Audits
Full reference reviews of a SaaS landing page, an e-commerce checkout, and a subscription conversion flow. Reference material developers can pattern-match against instead of starting from a blank page.
- Hierarchical Decision Framework
Psychology recommendations are weighed against brand identity, accessibility, and technical quality. The skill knows when to defer to your design system, not override it.
- Extensible CSV Databases
Principles and page-type mappings live in machine-readable CSVs. Add custom principles, override defaults, or extend the skill to new page types without touching SKILL.md.
