Research

Skills that put UX and accessibility at day zero

EvenBetter is a curated-skills framework for context-aware support in SwiftUI/iOS planning and accessibility-oriented auditing. It began as a Mackenzie TCC, grew into an open agent plugin, and is now a Springer-accepted workshop paper. Camera Ready is underway for JIIHC 2026 in Chile this November.

Path

From thesis to workshop

Five beats that turned a graduation project into an open research artifact headed to Chile.

From a Mackenzie TCC

Started as a graduation thesis at Universidade Presbiteriana Mackenzie, written by Marcello Birkan and Daniela Flauto and advised by Prof. Dr. Valéria Farinazzo Martins.

Curated skills, not prompts

Seventeen installable skills and forty-nine iOS clauses across seven domains, packaged as versioned SKILL.md procedures agents already understand.

Formative evaluation

Ten iOS developers walked discovery, planning, and audit-report tasks. Mean SUS landed at 79.5, which measures the usability of the interaction rather than the accuracy of the findings.

Springer workshop accept

Accepted at JIIHC 2026 / 8WoSI², the Workshop on Intelligent Interactive Systems, with proceedings through Springer.

Camera Ready · Chile

Camera Ready in progress for the November presentation in Talca, Chile. The public site and open framework stay the living artifact.

Motivation & proof

Why curated skills, and what we measured

Structural checkers leave a wide gap on mobile screen-reader issues. EvenBetter packages procedures so agents ask, inspect, and report while the developer keeps the final call. Ten iOS developers evaluated it formatively.

Structural coverage

Approximate share of mobile screen-reader errors caught by structural checks (ScreenAudit, CHI ’25)

LLM-driven coverage

Same evaluation class under semantic, model-led auditing. This gap is what motivates the work

Installable skills

Curated procedures across planning, audit, validation, and repair-oriented workflows

iOS clauses

Guideline-backed clauses across seven domains in the open corpus

Mean SUS

Perceived usability from ten iOS developers, which is not a certificate of finding accuracy

Developers in study

Formative sessions: discovery, agent-assisted planning, audit report interpretation

Artifact

The living framework

A public product site, an open GitHub corpus, and a research figure that maps how skills structure the loop between developer and agent. The artifact is something you can install rather than a PDF of the paper.

Open procedures for agents you already use

Distribution is part of the contribution: skills load into Codex, Claude Code, and similar agents through the open SKILL.md standard, with no proprietary IDE required.
