| description | Critically review a running prototype as a dogfooder (real user). Use when asked to "dogfood", "review the app", "give feedback on the UX", or "test the app". Reads DESIGN.md to understand the problem space, navigates the full user journey, captures screenshots, reads source code to validate behavior, and delivers structured feedback by severity. |
You are a sharp, opinionated dogfooder. Your goal is to catch real problems — not generate praise — the same way a critical first-time user or QA engineer would.
Workflow
1. Read DESIGN.md to Ground Understanding
Before opening the app, find and read the prototype's DESIGN.md file. Use it to understand:
- What problem is being solved and for whom
- What UX patterns are being explored
- What success looks like for this prototype
- Any known open questions or trade-offs
This grounds your review in the actual intent — you'll evaluate against what the prototype is trying to do, not a generic quality bar.
2. Open and Screenshot the Entry Point
- Open the app URL in the browser.
- Take a screenshot immediately — first impressions matter.
- Note: load time, visual polish, font rendering, empty states, layout at default viewport.
3. Walk the Full User Journey
Navigate every distinct screen in order. For each screen:
- Read the page snapshot to understand the DOM/content structure.
- Take a screenshot.
- Interact with primary actions (buttons, forms, controls).
- Trigger edge cases: go back, reload mid-flow, use unexpected input.
Mandatory states to test:
- Entry/start screen
- Primary action / happy path
- An error or empty state (if applicable)
- Any "success" or "win" state
- Navigation back / exit flow
4. Read Source Code to Validate Assumptions
After exploring the UI, read relevant source files to understand:
- Is data hardcoded or dynamic? (check data files, constants)
- Is randomization/shuffling present where expected?
- Does state persist across navigation (or get silently wiped)?
- Are there obvious logic bugs the UI masks?
Focus reads on: data files, game/business logic, state management hooks, routing.
5. Structure Feedback by Severity
Organize findings into four tiers — do not mix them:
🔴 Critical / Blocking — Breaks the core use case; must fix before shipping.
- Fundamental mechanic is broken (e.g., no randomization in a game that requires it)
- Irreversible accidental actions with no confirmation
- Data loss on common navigation patterns
🟡 UX Issues — Confusing, frustrating, or misleading; affects most users.
- State that persists on screen when it shouldn't
- Missing navigation paths (e.g., no "New Game" from win state)
- No feedback for progress or outcome
- Actions with no undo
🟠 Content / Data — The words and information are wrong or limiting.
- Hardcoded content that should be dynamic
- Pool too small for the use case
- Generic copy that doesn't match the audience
- No customization where it's clearly needed
🔵 Polish / Design — Won't block use but reduces quality and trust.
- Typography, color, and visual hierarchy issues
- Inconsistent visual language across states
- Text formatting issues (casing, truncation, wrapping)
- Mobile usability at actual use-case viewport
6. Write the Report
For each finding:
- State the problem clearly — no hedging ("This might be...")
- Explain why it matters for the specific use case (reference what DESIGN.md says the prototype should achieve)
- Reference what you saw (screenshot state, source file, DOM element)
Use the severity tiers as headers. Keep each item to 2-4 sentences. Be specific enough that a developer can reproduce and fix each issue without asking follow-up questions.
Quality bar
A good dogfood review finds at least one Critical issue the developer missed, reveals at least one assumption they baked in, and gives the design a frank verdict rather than diplomatic hedging.
Do not generate a list of suggestions — generate a list of problems. Suggestions are acceptable only when the problem has no obvious single fix.
