Evaluate and improve interface usability using heuristic analysis. Use when the user mentions "usability audit", "users are confused", "form usability", "navigation problems", "Nielsen heuristics", or "is this easy to use". Also trigger when reviewing a design for usability issues, improving form-completion rates, or evaluating information architecture and navigation. Covers Krug's laws, Nielsen's 10 heuristics, severity ratings, dark-pattern recognition, and accessibility. NOT for: visual…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# UX Heuristics Framework Practical usability principles for evaluating and improving user interfaces. Users don't read, they scan; they don't make optimal choices, they satisfice; they don't figure out how things work, they muddle through. ## Core Principle **"Don't Make Me Think"** — every page should be self-evident. If something requires thinking, it's a usability problem. Users have limited patience and cognitive bandwidth, so design for the scanning, satisficing, and muddling-through behavior described above. ## Scoring **Goal: 10/10.** Audit the interface, rate every issue on the severity scale below, then score the interface from its Quick Diagnostic results: start at 10 and subtract per failed diagnostic row, weighted by the worst severity it triggers (catastrophic/major rows cost ~2, minor/cosmetic ~1). Bands: **9-10** = no severity-3+ issues and ≤1 failed diagnostic row; **6-8** = some major issues or several failed rows; **3-5** = a catastrophic issue or many failed rows; **≤2** = core tasks blocked. Always state the current score, the highest-severity issues, and the specific fixes needed to reach 10/10. ## Shortest Worked Example …

How to install
mdr add ninjasln-labs/agent-skills/ux-heuristics@sha256:2943346a3eafb831The line at the top of this page pins the label v1.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
