Move an idea up the fidelity ladder (content-first → wireframe → low-fi → high-fi → code) with a validation plan at each level, plus user-journey mapping and usability-testing scripts. Use when the user wants to prototype, wireframe, map a user flow, or plan/run usability testing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: Prototype & Research
> **Step 0 — is the kit here?** This skill reads files from the kit. Check once:
> `ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING`
> On `KIT_MISSING` only the skill folders were installed, which is what
> `npx skills add` does. Say so plainly, point the user at
> `npx ux-ui-agent-skills init` or the plugin install, and stop. Do not guess the
> contents of a file you could not open.
Guide work through the right fidelity level with validation.
## Steps
1. Read `${CLAUDE_SKILL_DIR}/../../../workflows/prototyping.md` (5-level fidelity ladder, journey mapping template, usability-testing script, sample data).
2. Identify the current need and pick the **lowest** fidelity that answers it — never skip levels:
- Content-first (info needs) → Wireframe (layout/nav) → Low-fi (task completion) → High-fi (visual/a11y) → Code (feasibility/perf).
3. For flows: produce a user-journey map with decision points, error paths, and edge cases.
4. For validation: define the usability test (tasks, success criteria, 5-user rule) using the script.

How to install
mdr add plugin87/ux-ui-agent-skills/prototype@sha256:ef0401de8c758ed6The line at the top of this page pins the label git:20261006.5751441, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
