dotPilot: Skill for Codex

.codex/skills/mcaf-ui-ux/SKILL.md

mcaf-ui-ux is a skill for Codex from managedcode/dotPilot. It costs 50 tokens per session (770 once invoked), scanned A, a copy of dotnet-mcaf-ui-ux, MIT.

A UI and UX engineering guide covering design systems, accessibility, front-end technology choices, and collaboration between designers and developers. Accessibility means making interfaces usable by people with different abilities.

In plain words
What is it for?
Use it when starting a user interface project, choosing a front-end stack, improving accessibility practices, or defining how design work is handed to developers.
Why use it?
It helps connect visual and user needs to concrete implementation decisions instead of leaving them as vague design preferences.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcaf-ui-ux scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

97% identical to dotnet-mcaf-ui-ux — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

MCAF: UI/UX

Trigger On

  • bootstrapping a UI project
  • choosing front-end stack or design-system direction
  • tightening accessibility or design-to-development collaboration

Value

  • produce a concrete project delta: code, docs, config, tests, CI, or review artifact
  • reduce ambiguity through explicit planning, verification, and final validation skills
  • leave reusable project context so future tasks are faster and safer

Do Not Use For

  • pure backend or infrastructure work
  • vague visual taste debates with no delivery consequence

Inputs

  • user outcomes, device targets, and accessibility needs
  • design-system constraints and design handoff inputs
  • current front-end stack and delivery constraints

Quick Start

  1. Read the nearest AGENTS.md and confirm scope and constraints.
  2. Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
  3. Return the Required Result Format with concrete artifacts and verification evidence.

Workflow

  1. Start from user outcomes and accessibility needs, not framework preference.
  2. Tie design choices to implementation and delivery constraints.
  3. Pull only the references that match the active UI decision.

Deliver

  • better UI/UX delivery guidance
  • clearer front-end technology and accessibility decisions
  • design-system-aware development notes

Validate

  • accessibility is treated as a first-class requirement
  • technology choices serve the product and team constraints
  • design handoff guidance is actionable for engineers

Ralph Loop

Use the Ralph Loop for every task, including docs, architecture, testing, and tooling work.

  1. Brainstorm first (mandatory):
    • analyze current state
    • define the problem, target outcome, constraints, and risks
    • generate options and think through trade-offs before committing
    • capture the recommended direction and open questions
  2. Plan second (mandatory):
    • write a detailed execution plan from the chosen direction
    • list final validation skills to run at the end, with order and reason
  3. Execute one planned step and produce a concrete delta.
  4. Review the result and capture findings with actionable next fixes.
  5. Apply fixes in small batches and rerun the relevant checks or review steps.
  6. Update the plan after each iteration.
  7. Repeat until outcomes are acceptable or only explicit exceptions remain.
  8. If a dependency is missing, bootstrap it or return status: not_applicable with explicit reason and fallback path.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
