What problem does it solve?
Manually evaluating the user experience of field worker (FLW) apps is time-consuming, subjective, and often disconnected from original project design requirements. This skill eliminates that gap by providing a structured, rubric-based LLM judgment over captured app screenshots to objectively assess if the built app delivers a good experience for its intended users, with all judgments tied directly to concrete project design document (PDD) ground truth.
Core Features & Use Cases
- Structured UX Rubric Scoring: Grades 6 core UX dimensions (clarity, flow predictability, error recovery, time budget adherence, journey completion, and capture robustness) with weighted scores and hard deduction rules for critical failures.
- Pass/Fail Phase Verdicts: Produces per-journey and overall phase pass/fail verdicts to gate app launches, with clear surfacing of failure reasons and calibration tracking across runs.
- Use Case: For a Connect app build, run this skill after capturing test journey screenshots to get an objective UX quality score that determines if the app is ready for field deployment, with explicit flags for issues like dead-end errors or unvalidated negative-path input handling.
Quick Start
Invoke the app-ux-eval skill as part of the /ace:qa-deep workflow to automatically grade the field worker experience of your built app against project design document requirements using the latest captured test journey screenshots.
