Design Method

Read this first — before design-system, any register/*.md file, or any moves/*.md file. This skill owns the gate and the routing table, not the move procedures themselves.

Design Method — The Core

This is the one place the design pipeline is defined. The agent (agents/design-expert.md) always loads this file before dispatching to a move; every references/register/*.md and references/moves/*.md file assumes you've read this first and references it instead of restating it — if a rule elsewhere contradicts this file, this file wins.

Setup

How this core gets loaded, every time, no exceptions:

1. Read this file once per task — not once per move. Skip the re-read for a later move in the same task if neither the Register nor the codebase changed.
2. Read ../design-system/SKILL.md — always, unconditionally, before anything else below. Thin pointer file, cheap to reload, and the harness's phase-1 trigger, so it runs even on a task needing no new token. Existing design-system.md tokens still win over its defaults once resolved.
3. Resolve Register (below), then write the Design Read + 3 dials one-liner.
4. Pass Gate 0 — Brief Lock (below) before touching any HTML/CSS/tokens.
5. Read the ONE matched references/moves/<move>.md from the Routing table — not two, not a skim of several to "compare." The move file owns the how; this file owns the gate and the pointer.
6. If the move builds or touches code, read the matching references/register/{brand,product}.md floors too, once.

Register

Resolve before anything else downstream — brand vs product gates every floor (Signature Dominance, Focal-Block Floor, tone bounds, motion budget, dial presets). Never default silently.

• brand — one dominant, expressive message: marketing site, launch page, identity.
• product — dense, predictable, motion stays discreet: dashboard, SaaS tool, utility screen.

Priority order (fixed, first match wins):

1. The owner states it explicitly.
2. An existing design-system.md/PRODUCT.md already classifies it.
3. Inferable from the concrete surface (dashboard/settings/internal tool → product; landing/marketing/campaign/identity → brand).
4. Still unclear → ask ONE question. Never guess past this point.

Once resolved, load references/register/brand.md or references/register/product.md — each carries the floors, tone bounds and motion budget for that lane. For copy/microcopy tone, load references/register/copy.md (any move touching user-facing text, plus ux-copy).

Design Read + the 3 dials

Before any palette/font/layout choice, state one line:

Design Read: {page kind} for {audience}; vibe = {2-4 adjectives}; assets = {existing brand assets or "none"}; constraints = {quiet constraints or "none"}.

Then set the 3 numeric dials it implies — contractual inputs for every step after this one, not decoration:

Preset-by-use-case table, partial-brief fallbacks and MOTION_INTENSITY bands (calm <4 / expressive 4–7 / cinematic >7) live in ../design-system/references/design-read-dials.md — don't restate them here. The brief always overrides any default; an unresolvable dial uses the documented fallback and says so in the Design Read line, never a silent guess.

What each number means — anchored on the corpus

Poles alone are unusable: nobody knows what a 7 looks like, so an unanchored dial drifts to the middle and the middle is where every generated page already lives. The scales below are anchored on the fifteen reference pages, each value read from that page's own design-system.md under ../design-web/references/refs-design/ (short names below are those directories). These are not scores. All fifteen pages were judged good; the numbers say what kind of page it is, never how well it was done.

DESIGN_VARIANCE — how far the composition departs from the canonical skeleton.

VISUAL_DENSITY — how much is on screen per unit of scroll.

Read the fourth column before you copy a number from the first. Not one of the fifteen holds a low density with an empty screen. reve and supercommon sit at the corpus floor and still put fifty-one images and four media files in front of the reader; stripe holds the corpus's highest density on four images and zero <svg>, because it draws seven product screens in markup instead of capturing them — the same trick xai runs at 7. A density value says how much scroll a given quantity of matter is spread over. It never says how much matter there is. Copying 2 from reve onto a page with nothing to show does not reproduce reve — it reproduces the number and drops the page.

The screen-holding floor — checked at Gate 0, not after the build

A dial triple says how a page is composed. It says nothing about whether there is anything to compose. Three facts together leave the reader with nothing to look at:

• VISUAL_DENSITY ≤ 3, and
• DESIGN_VARIANCE ≥ 6, and
• no visual asset available — no photography, no video, no product UI, no data, no map, no document, no object.

Each is legitimate on its own. Together they are not a direction, they are an empty page: high variance drops the canonical furniture (card grids, logo walls, metric bands, testimonials) that would otherwise have filled the screen; low density spreads what remains over a long scroll; and with no asset there is nothing to put in the space the other two just cleared. The corpus contains no such page. supercommon, its closest point at 7 · 2, still ships three photographs, a video and a metallic band.

The check is countable, and it runs before code. List what will physically be on screen, block by block: every image, video, mockup, drawn interface, chart, table, full-bleed colour field, and every type object large enough to be a composition in itself. If that list holds fewer than one entry per planned section, one of three things has to change, and the plan says which:

1. Raise the density — bring back the furniture the variance dropped, and treat it (per-section padding rhythm, a rule crossing section boundaries) instead of leaving it plain. fora at variance 3 is a corpus reference precisely for this.

2. Manufacture the matter. Drawn matter counts, and it is the answer when the brief supplies no photography: xai holds density 7 on seven images by building its interface out of markup; supercommon makes a whole band out of a gradient and one 56px line; mainframe makes two halos out of a single image cut by opposite alpha masks.

   When the brief does supply usable photography, manufacturing matter instead is not a neutral choice — it is refusing what the subject actually has, and a page that then labels a section "photographed" over nothing but drawings contradicts itself in public. Drawing is a way of filling a screen; it is never a way out of using the client's images. Use them, and draw around them. And where the brief supplies none, a free-stock image is still reachable before a drawing is — sourcing rules live in design-web/references/photos-images.md, the source hierarchy is enforced at design-review/references/pre-flight-checklist.md check 15.

   Better still, carry both — they reinforce each other. Drawing and photography are not competitors, and a page holding both holds better than a page holding either alone. The division of labour is clean: the photograph carries matter, light, the real thing; the drawing carries structure, measure, and what the eye cannot see on its own — a section, a survey line, a scale, a before/after. Real estate and architecture are the plain case: a plan or a cross-section set beside a photograph of the place says what neither says alone, the photograph showing what it is like and the drawing how it is made. One limit, and it is intention: an SVG pictogram parked next to a photo is not this — this is a drawing that tells the reader something the photograph cannot.

3. Lower the variance — a canonical skeleton at least arrives with its own blocks.

What is never an answer is shipping the triple and letting body copy carry three screens on its own. Type at scale is matter — but only when it is the declared signature and treated as an object, the way supercommon's solitary display line opens the page, then every band after it, then returns split in two. Type left at body scale over an empty band is not a composition; it is a page that failed to get made.

MOTION_INTENSITY — how much of the page moves, and how far.

Read the corpus honestly on one point: at 6, motion is coverage, not amplitude — mainframe and harness earn a 6 because every state is covered by a documented system, not because anything is spectacular. 7 is now the corpus ceiling, and it was 6 until dispatch landed. Read what moved that number, because it is not what the scale's poles suggest: dispatch earns a 7 by adding three periodic animations and four scripted behaviours — including a genuine parallax at 0.18 × scrollY — on top of the same total, low-amplitude coverage the 6s have. Still no page on disk plays a pinned or scrubbed sequence. So 7 has one anchor and it is a modest one; from 8 up the scale has poles but no anchor at all. A brief that lands at 8 is not thereby wrong — it is unanchored, and the obligations under A high value commits you to producing something below are the only thing holding it. Say in the plan that nothing in the corpus demonstrates the value you claimed.

Notches nobody occupies — 1, 2, 8, 9, 10 on variance; 1, 3, 10 on density; 1, 2, 8, 9, 10 on motion — are not forbidden. Where the notch sits between two occupied ones, interpolate and say what the in-between buys you; where it sits above everything (variance 8+, density 10, motion 8+), there is nothing to interpolate from and the number is a promise with no precedent — treat it accordingly. And note what the corpus does not contain: no page is high on all three axes. Every one of the fifteen gives something up — harness is a 9 in density but a 4 in variance; supercommon is a 7 in variance but a 2 in density; stripe reaches 9 in density and pays for it at 6 · 6 on the other two; reve sits at the corpus floor on two axes at once, 5 · 2 · 3, and is the only page that does. The closest thing to an exception is dispatch at 7 · 7 · 7, and it is worth naming as such: it is the only page that refuses to give an axis up, and the price is visible — it carries the corpus's most complex motion budget on a page that also has to keep four recreated interfaces legible. A brief that arrives at 8/8/8 has not made a choice, it has made a wish.

One more thing the comparison exposes, and it now cuts both ways. Where a preset row sits below what the subject supports, the corpus proves it: the "SaaS / product landing" default is 4 · 5 · 4 where harness-recode, a SaaS landing, ships 4 · 9 · 6 — and no preset row anywhere reaches the 9 that harness holds. But two rows sit above everything on disk — agency 8 · 4 · 7 and luxury 5 · 3 · 7 both claim a variance or a motion value no page here occupies. Those two are unanchored in this corpus, so a brief landing on one of them cannot check its number against anything. Either way the rule is the same: the presets are a safe starting point for a thin brief, never a target, and the dial is argued from the subject.

Setting a dial is a decision, not a field

Each dial is argued from the subject in the same breath as the register and the tone, appended to the Design Read line:

Dials: DESIGN_VARIANCE n · VISUAL_DENSITY n · MOTION_INTENSITY n — because {what in the subject demands it}.

A law firm at DESIGN_VARIANCE 8 owes exactly the sentence a fashion label at 3 owes. Neither number is wrong; an unargued one always is.

A low value is not a low score. fora at variance 3, cursor at 3, reve at density 2 — all judged good. What separates a chosen low value from a timid one is that it is executed to the end: fora commits to a single 1px rule and uses nothing else; reve gives one capability the whole screen and never crowds it. A low value assumed and carried through beats a high value claimed and not delivered, every time.

The middle is suspect. Three 5s across three axes is the signature of a decision not made. It is not banned — but it is worth knowing that no page in the corpus carries a 5 on more than one axis. The two pages closest to the middle each buy it with a named device: umbrel (5 · 6 · 4) with its solo/duet alternation, mainframe (5 · 4 · 6) with a brand page that argues in the product register. So: if two or more dials land at 5, the plan says in one line why the middle is the answer here, or moves one of them. Flag it as such — a silent 5/5/5 is the failure this rule exists to catch.

A high value commits you to producing something. The number is a promise the deliverable has to keep:

• DESIGN_VARIANCE ≥ 7 obliges a macrostructure that visibly departs from the canon and a signature procedure derived from the subject, applied more than once. supercommon is the only page here that clears 7, and it carries both: its solitary display line opens the page and then every band after it, then returns split in two as stillness. / motion.; and its voids are metered — each silence sized to the block behind it, the two largest (32vh, 40vh) reserved for the two blocks the page most wants read. Without both, high variance is novelty, not direction.
• VISUAL_DENSITY ≥ 7 obliges a counted inventory of what is on screen and two spacing regimes — dense inside blocks, airy between them. Every high-density page in the corpus splits this way. Density without the second regime is noise.
• VISUAL_DENSITY ≤ 3 obliges the same counted inventory, for the opposite reason: it has to show that something still holds each screen. See The screen-holding floor above, and the fourth column of the density table — both corpus pages at 2 are carrying real matter. A low density with nothing counted is not restraint, it is an empty page.
• MOTION_INTENSITY ≥ 6 obliges a documented motion system: the material list, the duration set, the curve set, and entrances differentiated by role rather than one blanket reveal. Above 7, add a named scroll mechanism and its prefers-reduced-motion path.

If the deliverable does not carry the obligation, lower the dial in the plan rather than ship the number — a claimed 8 that the page does not hold is the more expensive mistake, because every downstream move inherits it.

The macrostructure pick and DESIGN_VARIANCE must agree. A canonical skeleton is a 3; a rebuilt-but-legible one a 5; dropped sections and a bespoke order a 7, which is where the corpus stops — no page on disk shows what an 8 or a 9 costs to hold. A plan naming the canonical skeleton next to DESIGN_VARIANCE 8 has one of the two wrong — resolve it before Gate 0, not while coding.

Gate 0 — Brief Lock

Before routing to any target skill — before writing or modifying a single line of HTML/CSS/tokens — six artefacts must exist in writing, not just in your head:

0. Register — resolved above, stated explicitly (not defaulted).

1. Tone committed to ONE extreme — not an adjective that could also describe three competitors. Where it comes from depends on whether tone is one of the axes the Exploration Gate put in play:

   • Explored — the gate fans out 3 divergent, text-only direction sketches judged blind and comparatively by fuse-ai-pilot:challenger, and the winner's tone becomes this artefact. The gate runs before Step 1 of generate wherever that move has a page body to decide — it is no longer a single scope/register special case.
   • Not explored — either no gate ran, or it ran on a reduced axis list because tone was already arbitrated in writing. Tone is then stated directly: generate derives it from the brief, refinement moves inherit it from the existing surface and name it. Inheriting is not skipping — an inherited tone left unstated fails this gate exactly like a missing one.

   Which case applies, and which axes each scope × register combination puts in play, is defined once, in the scope table of references/moves/generate.md (§Exploration Gate). Read it there. It is deliberately not restated here — two copies of one rule are two rules that drift apart, and that file also owns the mechanics, the "reduced is not lighter" rule, and the fallback.

   The fallback survives unchanged and is the only route back to an unexplored direction when the gate was due: Task/Agent unavailable at nesting depth 5 → the direct single pick, and the report marked "direction not explored / single-fiat". Never a silent one.

2. Signature element (brand register) or primary task (product register) named in one sentence.

3. The corpus actually seen, then read — in that order, and both halves are required:

   • at least two of the fifteen pages opened in a browser and scrolled through, named in the plan as {reference}-recode/index.html. They open by double-click, file://, no server, no build;
   • design-web/references/refs-design/README.md plus at least two tokens-*.md sections, cited by reference and section name.

   This is the evidence artefact, per design-web/references/design-inspiration.md. Sections cited with no page opened does not satisfy it. Measured values let you reproduce a procedure, never choose one, and a corpus of taste that is only ever read hands back conformity instead of judgment — the failure is documented at design-web/references/refs-design/README.md §Look before you read. A sector URL or a supplied screenshot is an addition to this artefact, never a substitute for either half.

4. What will be on screen, counted — one list, block by block, of the images, videos, mockups, drawn interfaces, charts, tables, full-bleed colour fields and display-scale type objects the page will actually carry. Required unconditionally, and decisive whenever VISUAL_DENSITY ≤ 3 or DESIGN_VARIANCE ≥ 6: see The screen-holding floor above for what to do when the count comes up short. A plan that names a dial triple but cannot say what fills the screen has not been made.

5. Structure named, both halves — one line in the plan:

   Macrostructure: {hero treatment from references/macrostructure-bank.md} + {body sequence from references/body-sequence-bank.md}
   

   Naming one without the other fails this gate. The two banks are separate on purpose: the hero bank owns the first screen only, the body-sequence bank owns everything after it. The body, not the hero, is the documented failure mode (references/register/brand.md intro) — a plan that names a hero treatment and stops has improvised the scroll, and improvised scrolls converge on the same feature-grid-then-testimonials default the corpus was assembled to break. So an unnamed body sequence is a missing artefact, not a detail to settle while coding.

   Restate the sequence's ordering principle in the brief's own terms, not the bank's label: "four chambers, one image transformation each" is a body sequence, "alternating" is a word. And the pick has to agree with DESIGN_VARIANCE (see the dial section above) — a canonical skeleton and a variance of 8 cannot both be true.

   Where the Exploration Gate ran, this pair is its output, not a fresh pick: the winning sketch's hero treatment + body sequence, carried forward with its principle line. Recording it satisfies this artefact; re-deciding it discards the comparison that was just paid for. Where no gate ran, pick both from the banks here.

This is a present/absent check on six named artefacts — structural, not a taste judgment. One missing ⇒ generation or modification is forbidden until it exists. Mechanics of artefacts 1–2 (the Exploration Gate and its scope table, brief questions, signature element, two-pass critique) live in references/moves/generate.md; the two banks own the vocabulary of artefact 5. This section is only the checkpoint every move respects before it's allowed to touch code — it says what must exist, never how it was produced.

Design guidance

Dense and general, applying whichever move is running — taste rules specific to one move live in that move's file.

Absolute bans

Match-and-refuse, unconditional across both registers — not a statistical reflex to weigh, a hard stop. If you're about to write any of these, rewrite the element with a different structure, never a variation on the same idea.

• Side-stripe borders — border-left/border-right >1px as a colored accent on cards, list items, callouts, or alerts. Rewrite with full borders, background tints, leading numbers/icons, or nothing.

• Gradient text — background-clip: text combined with a gradient background. Decorative, never meaningful. Single solid color; emphasis via weight or size.

• Glassmorphism as default — blurs/glass cards used decoratively rather than rare and purposeful, or nothing.

• The hero-metric template — big number, small label, supporting stats, gradient accent. SaaS cliché; see register/brand.md §2 "Ribbon 4-stats" furniture for the fix.

• Identical card grids — same-sized cards, icon + heading + text, repeated endlessly.

• Modal as first thought — modals are usually laziness. Exhaust inline/progressive alternatives first.

• Em dash in copy — commas, colons, semicolons, periods, or parentheses instead. Also not --.

• The AI-slop signature triad — defined here and canonical here; every other file in the pipeline points back to this bullet instead of restating it. Three tells that each pass on their own and together fingerprint the page:

  1. a Tailwind blue/indigo primary or accent, hue range 200–290°;
  2. Inter as the primary typeface;
  3. rounded-2xl as the default radius.

  That palette/font/radius combination is shared by ~83% of sampled AI-generated pages (grounding: sailop ai-slop research). The figure belongs to this triad and to nothing else — never quote it for another ban, another detector, or a general anti-slop claim.

  Any two legs are survivable; the third is what makes the page identifiable. So if brand guidelines already fix 2 of the 3, the third MUST change — another hue, another radius, or another typeface (reflex-reject list and alternatives: design-system/references/forbidden-fonts.md). The corpus carries the counter-example: fora-recode and umbrel-recode both ship Inter and both read specific, because neither carries either of the other two legs.

Deterministic grep companions for the structural ones (side-stripe, identical grids, nested cards, icon-bento): design-review/references/anti-ai-slop-audit.md.

The AI-slop test — 2 levels

If someone could look at this interface and say "AI made that" without doubt, it's failed. Run at two altitudes — the second catches what the first misses. Cross-register failures are the Absolute bans above; register-specific failures live in each register/*.md.

First-order — category reflex. If someone could guess the theme + palette from the category alone, it's the first training-data reflex:

1. Cream #F4F1EA + a contrasted serif + terracotta accent — the default "editorial SaaS" look.
2. Near-black background + one acid accent color — the default "dark developer tool" look.
3. Broadsheet hairlines, zero border-radius, black/white only — the default "premium minimal" look.
4. Glassmorphism + rounded-2xl used globally — the default "2026 AI app" look, applied everywhere instead of gated (design-motion gates it deliberately).
5. Generic icon-bento — every cell centered text over a round colored-icon badge, zero image/gradient/pattern variation between cells.

Rework the Design Read's vibe words and the color strategy (design-system §Color strategy) until the answer isn't obvious from the category — "observability → dark blue", "healthcare → white + teal", "finance → navy + gold", "crypto → neon on black" are all this tier. Purple-on-white gradients are banned outright regardless of tier — the single most common tell.

Second-order — category-plus-anti-reference trap. The first reflex was avoided, but if someone could still guess the aesthetic family from category-plus-anti-references — "AI workflow tool that's not SaaS-cream → editorial-typographic", "fintech that's not navy-and-gold → terminal-native dark mode" — it's the trap one tier deeper. Rework until neither answer is obvious. Register-specific reflex-reject aesthetic lanes: register/brand.md and register/product.md.

Deterministic grep detectors cover the first-order clusters plus the Absolute bans; the second-order trap is judgment, checked at the challenger gate (design-review/references/review-procedure.md), not grep-lintable.

Macrostructure variety — hero AND body

Centered hero + 3-column icon-card grid is forbidden as a default skeleton. Before any plan is finalized, name two picks: a hero treatment from references/macrostructure-bank.md (first screen only) and a body sequence from references/body-sequence-bank.md (everything after it, with its ordering principle restated in the brief's own terms). A plan carrying only a hero treatment has improvised the scroll — the body is the documented failure mode.

Following the canon is a legitimate pick. fora-recode's "Bookended Canon" runs the canonical skeleton almost to the letter and does not read generic, because one device — a single 1px rule at white 10% — is carried through every edge, card and divider. endlesstools-recode keeps the same order and fills every slot with footage. Departing is equally legitimate: supercommon-recode's "Void-Metered Stack" drops the testimonials, the pricing table, the FAQ, the CTA band and the nav outright — the price is inline on one button and the exit is a single link with no headline above it. What is never legitimate is not choosing — the skeleton that arrived by default is the one that reads as generated.

Let each pick follow the subject, not habit: a treatment or a sequence reused by reflex across briefs becomes its own template, whichever one it is. A pick used on two consecutive briefs has to be argued from the second subject or replaced — the fact that it worked once is not an argument.

Non-negotiable floor

Regardless of tone, register, target, or move, every deliverable must have: responsive behavior across the target's breakpoints/size classes; visible keyboard focus on every interactive element (:focus-visible, never suppressed); prefers-reduced-motion respected wherever motion is added.

Generation approach

Generate HTML/CSS directly — the default and primary path, following the same method as Anthropic's official frontend-design skill (commit to a point of view, avoid templated defaults, verify with tools not vibes). Gemini
