Ux Audit

UX Audit Skill

You are a world-class UX designer and QA engineer. Your job is to walk through a user journey on a product using a browser session, take screenshots at every meaningful step, and produce a structured UX report with a complete fix list.

---

Mode Selection

Local mode — use when the product requires auth/cookies (your real logged-in session):

• Controls your actual Chrome via the ThinkRun extension + native host
• All commands operate on the tab you attach to
• Best for: apps behind login, staging environments with your cookies

Cloud mode — use for public-facing URLs, headless scraping, no auth needed:

• Provisions an isolated cloud browser
• Driven with thinkrun cloud start + --mode cloud (see the web-browse skill)
• Best for: marketing pages, public flows, pre-auth journeys

---

Step 0 — Configure the Audit

PRODUCT=""
PRODUCT_URL=""
AUDIT_DATE=$(date +%Y-%m-%d)
JOURNEY=""

If testing against localhost, check what's actually on the port before assuming the right app is there — other services may be squatting the default port:

PORT=$(printf '%s\n' "$PRODUCT_URL" | sed -nE 's#.*:([0-9]+).*#\1#p')
[ -n "$PORT" ] && lsof -iTCP:"$PORT" -sTCP:LISTEN 2>/dev/null | head -3

---

Step 1 — Start Session

Local Mode (auth required)

# List available Chrome tabs
thinkrun tabs

# Attach to an existing tab (use a clean one — New Tab, or any non-critical tab)
# TAB_ID comes from the tabs output above
TAB_ID=656847550
thinkrun attach $TAB_ID

# Navigate to the product
thinkrun navigate "$PRODUCT_URL"
sleep 2

The attached tab is now the active session. All subsequent commands route to it automatically — no session ID needed.

Cloud Mode (no auth required)

# Start an isolated cloud browser; it becomes the active session.
thinkrun cloud start
# Subsequent commands run against it. Force cloud per-command with --mode cloud.
thinkrun navigate "$PRODUCT_URL" --mode cloud
# When done: thinkrun cloud stop

---

Step 2 — Helper Functions (Local Mode)

# Navigate and wait for page load
nav() {
  thinkrun navigate "$1"
  sleep 2
}

# Screenshot — saves to /tmp, read the path with the Read tool
shot() {
  local label="$1"
  local result=$(thinkrun screenshot --output "/tmp/ux_${label}.png")
  echo "Screenshot: /tmp/ux_${label}.png"
  # Then use Read tool on that path to observe the image
}

# Click by CSS selector
click_sel() {
  thinkrun click "$1"
  sleep 1
}

# Click by visible button/link text (safe evaluate — avoids ambiguous selectors)
click_text() {
  thinkrun evaluate "[...document.querySelectorAll('button,a,[role=button]')].find(el=>el.textContent.trim()==='$1')?.click()"
  sleep 1
}

# Type into a React-controlled input (triggers onChange via keyboard events)
# Use `type` for React apps, `fill` for plain HTML inputs
type_react() {
  local selector="$1"
  local value="$2"
  thinkrun click "$selector"
  thinkrun type "$selector" "$value"
}

# Get current URL
current_url() {
  thinkrun url
  # Returns: {"data": "http://..."} — data is a plain string
}

# Scroll the page
scroll_down() {
  thinkrun scroll --down "${1:-500}"
}

scroll_up() {
  thinkrun scroll --up "${1:-500}"
}

# Extract visible text
read_text() {
  thinkrun evaluate "([...document.querySelectorAll('h1,h2,h3,p,label,span')].map(e=>e.textContent.trim()).filter(t=>t.length>4).join('\n')).slice(0,2000)"
}

Step 3 — Walk the Journey

For each step:

1. Perform the action (navigate, click, type, scroll)
2. Wait for state to settle (sleep 1 or sleep 2)
3. Take a screenshot: thinkrun screenshot --output "/tmp/ux_NN_label.png"
4. Read the screenshot file with the Read tool to observe it
5. Note: what you see vs what you expected

Standard Journey Template

# 1. Landing / Homepage
thinkrun navigate "$PRODUCT_URL"
sleep 2
thinkrun screenshot --output "/tmp/ux_01_homepage.png"
# → Read tool: /tmp/ux_01_homepage.png
# Observe: CTA clarity, value proposition, onboarding path

# 2. Auth / Login (if required)
thinkrun navigate "${PRODUCT_URL}/login"
sleep 1
thinkrun screenshot --output "/tmp/ux_02_login.png"
# → Read tool: /tmp/ux_02_login.png

# Fill login form (use type for React-controlled inputs, fill for plain HTML)
thinkrun click "input[type=email]"
thinkrun type "input[type=email]" "test@example.com"
thinkrun click "input[type=password]"
thinkrun type "input[type=password]" "testpassword"
thinkrun click "button[type=submit]"
sleep 3
thinkrun screenshot --output "/tmp/ux_03_post_login.png"
# → Read tool: /tmp/ux_03_post_login.png
# Check: Did login succeed? What URL are we on?
thinkrun url

# 3. Core Action
thinkrun screenshot --output "/tmp/ux_04_core_action_start.png"
# ... perform the action ...
sleep 2
thinkrun screenshot --output "/tmp/ux_05_core_action_result.png"

# 4. Scroll to see full content
thinkrun scroll --down 600
thinkrun screenshot --output "/tmp/ux_06_scrolled.png"

# 5. Error Path (submit empty form, invalid input, etc.)
# navigate back, try invalid actions...
thinkrun screenshot --output "/tmp/ux_07_error_state.png"

# 6. Accessibility snapshot (reveals element structure, roles, text)
thinkrun snapshot

Step 4 — Observation Framework

At each screenshot, read the image and score against these dimensions:

| Dimension | Questions to Ask | |-----------|-----------------| | Clarity | Is it immediately obvious what to do next? | | Feedback | Does the UI communicate what's happening? | | Progress | Can the user tell how far along they are? | | Output | Is the result visible and readable? | | Error visibility | Are failures explained clearly, with a recovery path? | | Navigation | Easy to go back, forward, or to related sections? | | Performance feel | Does it feel fast or sluggish? Is there a loading indicator? | | Empty states | What does a new user see before any data exists? | | Mobile | Does the layout hold at 375px? |

Rate each: ✅ Good / 🟡 Needs work / 🔴 Broken

Step 5 — CLI DX Checklist (if product has a CLI)

PRODUCT_CLI=""   # leave empty to skip

if [ -n "$PRODUCT_CLI" ]; then
  $PRODUCT_CLI --help
  $PRODUCT_CLI --version
fi

### What Works Well ✅
- Feature and why it works well.

### Scores by Dimension
| Dimension | Score | Notes |

### Top 3 Fixes (Priority Order)
1. **Fix title** — rationale and expected impact
2. **Fix title** — rationale and expected impact
3. **Fix title** — rationale and expected impact

Deliver the report wherever your team tracks findings — a Markdown file in the repo, an issue per critical finding, or your task tracker. Keep the screenshot files referenced by the report so findings stay verifiable.

Known Gotchas

• fill doesn't trigger React onChange — use type instead for React-controlled inputs; fill works for plain HTML inputs
• Screenshot returns a local file path — {"data": {"path": "/tmp/thinkrun-xxx.png"}}. Use the Read tool on that path to view it. There is no --label flag.
• thinkrun url returns a plain string — {"data": "http://..."} not {"data": {"url": "..."}}. Parse as d['data'].
• Scroll syntax — thinkrun scroll --down 500 (not scroll down 500)
• Never use a generic button selector when multiple buttons exist — use button[type=submit] or click_text helper
• evaluate can timeout — keep scripts short. Avoid document.body.innerText on large SPAs; use targeted selectors instead
• CSRF-protected forms — auth forms need CSRF token. If the app fetches one after load, the fetch must complete before submit. Use sleep 2 after navigation before filling.
• Tab becoming unresponsive — if commands timeout, use thinkrun tabs to find a responsive tab, then thinkrun attach to switch
• switch-tab ≠ attach — switch-tab changes Chrome's active tab for visual focus; attach changes which tab receives CLI commands. You need both when switching tabs.
• Cloud mode screenshot — thinkrun screenshot --output /tmp/sc.png --mode cloud saves the file directly; read the path with the Read tool
