Design Review

If unclear, ask the user which stage. Default to Interaction if they describe a flow, Visual/Detail if they describe a screen.

Step 1 — Understand the Decision

If the user hasn't provided enough context, ask ONE clarifying question. You need:

• What is being designed (screen, component, interaction, device detail, animation, layout)
• Which platform (iOS, web, device e-ink, watchOS, widget, VS Code, macOS menu bar, Android)
• What state (active use, idle/rest, transition, onboarding, error)

Step 2 — Run the Philosophy Filter

Evaluate against the 10 PomoFocus principles. Not all will be relevant — only address the ones that meaningfully apply. For each relevant principle, give a verdict: Aligned, Tension, or Conflict.

After scoring, identify the 2-3 principles most critical to this specific decision and weight your recommendation toward those. Not all principles are equally important for every decision.

Step 3 — Usability Hygiene

Check these heuristics (from Nielsen) that the philosophy doesn't cover:

• System status: Does the user always know what's happening? (timer state, sync, BLE connection)
• Error prevention: Does the design prevent mistakes before they happen?
• Recognition over recall: Can the user see options rather than remembering them?
• User control: Can the user undo, go back, or exit without penalty?

Step 4 — Accessibility Check

At minimum, verify:

• Color contrast meets WCAG 2.2 AA (4.5:1 text, 3:1 UI)
• Touch/click targets meet platform minimums (44pt iOS, 48dp Android)
• Screen reader support (labels, roles, traits)
• prefers-reduced-motion respected for any animations
• Cognitive load is appropriate (aligns with Emptiness principle)

Step 5 — Deceptive Design Check

Scan for manipulation patterns — especially important for a productivity app:

• Confirmshaming: Does declining/canceling use guilt language?
• Streak guilt: Does the app shame broken streaks or missed sessions?
• Nagging: Does it repeatedly ask for something the user declined?
• Obstruction: Is canceling as easy as subscribing?
• Loss aversion: Does messaging exploit fear of losing progress?
• Visual interference: Are decline/cancel buttons visually suppressed?

The PomoFocus test: if it makes the user feel guilty, anxious, or trapped — it's deceptive. See references/checklists.md for the full checklist.

Step 6 — Platform Compliance

If the platform is known, check against the platform-specific checklist in references/checklists.md. Call out any violations of platform conventions (iOS HIG, Material Design 3, watchOS guidelines, etc.).

Step 7 — Give Your Recommendation

Structure your response as:

Review stage: [Concept / Interaction / Visual / Pre-ship]

Verdict: One sentence — does this align with the philosophy, and how?

What's working:

• Bullet points on what aligns well (always lead with positives)

What needs attention:

• Bullet points on tensions or conflicts, each citing the specific principle and designer/movement

Recommendation:

• Your specific suggestion, with rationale tied to the philosophy

The reference: Name the designer, movement, or principle that most directly applies. Give a one-line quote or reference.

Guiding Behaviors

• Never say "it depends" without following with a specific recommendation. Always commit to a direction.
• Always cite the source principle. Don't say "this should be simpler." Say "this should be simpler — Hara's emptiness principle: the focus session screen should approach blankness."
• Favor the specific over the general. Don't say "consider the user's emotions." Say "the post-session moment is Norman's reflective level — the completion message should acknowledge effort, not just time elapsed."
• Be honest about tensions. When principles conflict, name the tension and recommend which should win for this case.
• Respect the platform. Reference the platform checklist in references/checklists.md. Don't give generic advice.
• Lead with what's working. Research shows positive anchoring improves receptivity to critique (Critical Design Strategy, Roberts et al. 2026).

The Short Version

When in doubt: Would Naoto Fukasawa look at this and say "Of course"?

If the answer is no — if it requires explanation, feels clever rather than obvious, or draws attention to itself — it needs more work.

The goal is not to win design awards. The goal is something people use every day without thinking about it, that makes them feel a little more in control, and that they'd miss if it were gone.
