Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00790 |
| Opus 5.5 | $0.00021 | $0.00316 |
| Sonnet 5.5 | $0.00011 | $0.00158 |
| Haiku 4.5 | $0.00005 | $0.00079 |
Grade A, and why
dotnet-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.
This is a copy
97% identical to dotnet-mcaf-ui-ux — 2 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
- Read the nearest
AGENTS.mdand confirm scope and constraints. - Run this skill's
Workflowthrough theRalph Loopuntil outcomes are acceptable. - Return the
Required Result Formatwith concrete artifacts and verification evidence.
Workflow
- Start from user outcomes and accessibility needs, not framework preference.
- Tie design choices to implementation and delivery constraints.
- 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.
- 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
- 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
- Execute one planned step and produce a concrete delta.
- Review the result and capture findings with actionable next fixes.
- Apply fixes in small batches and rerun the relevant checks or review steps.
- Update the plan after each iteration.
- Repeat until outcomes are acceptable or only explicit exceptions remain.
- If a dependency is missing, bootstrap it or return
status: not_applicablewith 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.
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.

dotnet-mcaf-ui-ux is a skill published in the GitHub repository Postpartum-genushyacinthus29/dotnet-skills (13 stars, last pushed 14d ago), licensed MIT. It adds 53 tokens to every session and 790 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 97% identical to dotnet-mcaf-ui-ux, differing in 2 lines, and is treated as a copy.
