57%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The skill is well-structured for navigation — a clear overview with perfectly signaled one-level-deep references to 10 real, substantive bundle files — and offers genuinely actionable tables, checklists, and thresholds. Its main weaknesses are token efficiency (it re-teaches Norman's well-known framework and includes an author biography and affiliate book links Claude doesn't need) and the absence of a single unified review workflow with a validation loop tying the diagnostic, scoring, and fix-recommendation pieces together.
Suggestions
Cut the 'About the Author' section and the affiliate-linked 'Further Reading' section, and compress textbook explanations (thermostat example, HCD process, slips/mistakes definitions) to one-line pointers into the existing reference files — Claude already knows Norman's framework, so SKILL.md should keep only the decision-relevant tables, rules, and thresholds.
Add one unified ordered workflow near the top (e.g., 1. Run the Quick Diagnostic, 2. Score 0-10 per the Scoring section, 3. Map each failed diagnostic to the relevant principle's fixes, 4. Re-check that every fix is testable against the 10-second discoverability test) so the scattered procedures become a single sequence with an explicit verification step.
Include a short worked example of the scoring workflow applied to one interface (e.g., a form with a submit button) showing score, reasoning per principle, and improvements to reach 10/10, which would close the actionability gap in the skill's core use case.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is noticeably verbose for material Claude already knows: it re-explains textbook DOET content ("Norman's key insight: There is no such thing as 'human error.'", the thermostat example, the HCD process, "5 users reveal 85% of problems"), includes an "About the Author" biography of Don Norman, and affiliate-linked book recommendations — several padded sections that earn no tokens. It avoids a 1 because much of the length is genuinely useful tabulated reference (digital signifier/mapping/constraint tables, response-time thresholds) rather than rambling prose. | 2 / 5 |
Actionability | For an instruction-only skill the guidance is concrete: a scoring protocol ("rate 0-10... Always provide current score and improvements to reach 10/10"), a falsifiable test ("figure out what to do within 10 seconds"), specific thresholds ("0.1s: Feels instantaneous... 10s: show progress bar"), an error-message checklist, and a Quick Diagnostic table mapping questions to fixes. Not a 5 because the central review workflow is never demonstrated — there is no worked example scoring a real interface, and directives like "Walk through each stage... Where does the user get stuck?" leave the procedure to be assembled by the reader. | 4 / 5 |
Workflow Clarity | Usable procedure fragments exist (Quick Diagnostic audit table, seven-stage walkthrough, scoring protocol), but they are scattered across the document with no unified ordered workflow — nothing tells Claude to first run the diagnostic, then score, then map gaps to principles, then propose fixes. There is also no validation/feedback loop (e.g., re-scoring after proposed improvements). This fits 'steps listed but checkpoints missing or implicit' rather than a 4, since the sequence itself must be inferred. | 3 / 5 |
Progressive Disclosure | Structure is exemplary: each principle section ends with a clearly signaled one-level-deep pointer ("See: references/affordances.md for affordance design patterns"), and a consolidated Reference Files section lists all 10 bundle files with descriptions. All 10 referenced files exist and contain real content with no nested references, so navigation is easy and content is appropriately split between overview and bundle. | 5 / 5 |
