## Setup
1. Run `node .github/skills/impeccable/scripts/context.mjs` once per session (if the runtime shows this skill's loaded base directory, run `node <skill-base-dir>/scripts/context.mjs`; keep cwd at the user's project). It prints the project's PRODUCT.md and DESIGN.md when they exist; follow what it prints, including any `UPDATE_AVAILABLE` directive (ask once, never block). If it reports `NO_PRODUCT_MD`: for `init`, `teach`, `craft`, `shape`, or wording that clearly maps to a from-scratch build flow, divert into `reference/init.md` first, **unless no user can respond** (a one-shot or automated run, or the user said not to ask): then write your own one-paragraph understanding of the product, audience, and the page's job from the brief and continue. For scoped evaluate/refine/fix requests against existing code, never divert into init; the existing code is the context.
2. If the user invoked a sub-command (`audit`, `polish`, `live`, ...), read **`reference/<command>.md`** (the `.native` variant from the Commands table when the platform is `ios`/`android`/`adaptive`) and follow it. `craft` and `shape` requests follow the build path: the new-work gate below owns the flow, and on unattended runs its checkpoints resolve without pausing.
1. Run `node .github/skills/impeccable/scripts/context.mjs` once per session (if the runtime shows this skill's loaded base directory, run `node <skill-base-dir>/scripts/context.mjs`; keep cwd at the user's project). It prints the project's context and its directives; follow what it prints. Once its output is in the conversation, never rerun it on a later turn.
2. `craft` and `shape` are build-path exceptions: the new-work gate below owns their flow, and on unattended runs its checkpoints resolve without pausing. For any other invoked sub-command (`audit`, `polish`, `live`, ...), immediately read **`reference/<command>.md`** after `context.mjs` (the `.native` variant from the Commands table when the platform is `ios`/`android`/`adaptive`) and follow it. This read is a hard gate: do not inspect the target, run command-specific scripts, or edit files until the reference is loaded.
3. Read at least one project file (CSS / tokens / theme / a representative component) to learn what world you're in. If PRODUCT.md's `## Platform` is `ios` or `android`, also read `reference/<platform>.md` (`adaptive` reads both).
## How to design
**The brief wins.** Where the brief pins down a direction (a named aesthetic, an era, a place, a material, a specific font or palette), follow it exactly, including when it asks for a look this skill warns is saturated. Redirecting a pinned direction toward your own taste is a failure, not a save.
**Existing worlds are sacred.** Most of impeccable's work happens inside a site or app that already exists. When the surface has a committed design system (real tokens, deliberately chosen faces, a palette the brand owns), work inside that world: extend it, sharpen it, leave it unmistakably the same brand, and never degrade a working page's performance. Inventing parallel colors, fonts, or styles on an existing surface is a defect, not creativity.

When the surface has a committed design system (real tokens, deliberately chosen faces, a palette the brand owns), work inside that world: extend it, sharpen it, leave it unmistakably the same brand, and never degrade a working page's performance. Inventing parallel colors, fonts, or styles on an existing surface is a defect, not creativity. A scoped refinement keeps the named scope's content and media footprint unless the brief explicitly changes them; build the added emphasis by recomposing what is already there through hierarchy, proportion, rhythm, and the system's own motifs.
**New identity work reads the playbook first.** When nothing committed exists (greenfield, or a codebase with no real tokens or chosen faces), or the user asks for a redesign that discards the current look, you MUST read [reference/new-work.md](reference/new-work.md) before making any design decision. Not optional, not skippable under time pressure: producing new identity without it yields the generic default this skill exists to prevent. A redesign is new work; derive the concept from the subject and the brief, not from the incumbent page's structure or styling. `context.mjs` prints this directive when it detects the situation. Scoped fixes inside an existing world don't need the playbook; the craft floor below governs them.

## Craft floor
Build to this floor without announcing it. The design detector (the project hook, `node .github/skills/impeccable/scripts/detect.mjs --json <file>`, or `audit`) verifies most of it mechanically; any finding it raises is a defect to fix, not a suggestion.
- Contrast: body text ≥4.5:1 against its background (placeholders too); large text ≥3:1. Gray text on a colored background looks washed out: use a darker shade of the background's own hue, or a transparency of the text color.
- Shadows describe real light: an offset and a soft blur. A zero-offset colored halo is decoration announcing itself.
- Spacing has rhythm: generous separations, tight groupings; cramped padding reads as broken. Watch CSS specificity: classes that cancel each other's padding (a `.section` fighting a `.cta`) silently collapse section spacing. Verify computed spacing, not intended spacing.
- Type: body line length 65-75ch; display clamp() max ≤6rem; letter-spacing ≥-0.04em; `text-wrap: balance` on headings; modular scale ≥1.25 between steps; light-on-dark adds 0.05-0.1 line-height. Pair faces on a contrast axis, never two similar-but-not-identical ones; one family with committed weight contrast beats a timid pair. Test headings at every breakpoint; overflow means reduce the clamp or rewrite the copy.
- Structural devices (numbering, eyebrows, dividers) must encode something true about the content; the same device repeated above every section regardless of content is scaffolding.
- Motion is part of the build: one orchestrated moment beats scattered effects; ease-out exponential curves; `prefers-reduced-motion` alternatives always; reveals enhance an already-visible default (content gated on a class-triggered transition ships blank in hidden tabs and headless renderers). Responsive down to mobile and visible keyboard focus are part of the floor.
- Ship real content (no placeholders, dead links, or fake controls), cover the interaction states people will actually hit (hover, focus, disabled, loading, error, empty), and respect the project's build pipeline: edit source, never write into build output directly.
- Before finishing, re-read the brief: every requirement it names must exist on the page, findable in seconds. A beautiful page missing an asked-for feature is unfinished.
- Copy is design material: write from the user's side of the screen, active voice, a control says exactly what happens, errors explain what went wrong and how to fix it. Specific beats clever.
## Registers
## Modes
Name the visitor's mode before designing; the page's grammar follows from it, and most ruined pages are one mode wearing another mode's grammar. **The mode belongs to the surface, not the subject**: a landing page for a dense technical tool is still Persuade, with Persuade's full permission to be striking; a docs page for a fashion house is still Read. Deciding a page can be plain because its subject is workmanlike is the same category error in reverse. The brief and the surface decide the mode; PRODUCT.md's `register` field survives only as a family hint (`brand` covers Persuade and Experience, `product` covers Operate and Read). Depth beyond the paragraphs below: [reference/new-work.md](reference/new-work.md) when inventing identity, [reference/operate.md](reference/operate.md) for substantial Operate and Read work.
**Persuade** (landing pages, marketing, campaigns; design IS the product). The deliverable is an impression that stops the scroll, earns the click, converts. Spans every genre (tech, luxury, consumer); don't collapse them into one look. Briefs that imply imagery must ship real, verified imagery; a colored rectangle where a photo belongs reads as incomplete. New Persuade surfaces take their typeface procedure and reject list from [reference/new-work.md](reference/new-work.md).

New Persuade surfaces take their typeface procedure and reject list from [reference/new-work.md](reference/new-work.md).
**Operate** (app UI, dashboards, admin, tools; design SERVES the task). A person getting something done: density, scanability, and consistency outrank expressiveness. These surfaces earn trust by feeling native to their platform: system font stacks and workhorse UI faces are legitimate and often correct here (the Persuade reject list does not apply). The brand lives in the details: focus states, empty states, microcopy, one owned accent. The usage scene is part of the spec: an interface read outdoors, in motion, or at a glance must survive its real ambient light, and the theme follows the scene, not the category's habit.

Density follows the reader's task, not atmosphere, and nothing stands between the reader and the answer. The brand lives in type, spacing, and small accents.

The brand lives in type, spacing, and small accents.
**Experience** (an album, a portfolio, a publication, a body of work). The page IS the work: the artifact leads, the interface recedes, and the visitor meets the work itself in the first viewport at every screen size. Boldness here means trusting the work.

- Before finishing, re-read the brief: every requirement it names must exist on the page, findable in seconds. A beautiful page missing an asked-for feature is unfinished.

When asked for "bolder," AI defaults to the same tired tricks: cyan/purple gradients, glassmorphism, neon accents on dark backgrounds, gradient text on metrics. These are the opposite of bold. Reject them first, then increase visual impact by making the existing design language more decisive, specific, and committed.
> **Additional context needed**: which section is the target, and what must stay untouched.
---
"Bolder" is an amplification request, and almost always it is scoped to something that already exists. The surrounding page, its system, and its conventions are the given. Your job is to raise one part to the conviction the rest already implies, without rebuilding anything the brief did not name. The reflex answer, reaching for more effects, is the opposite of bold; reject it first.
## Register
## Scope is sovereign
Persuade + Experience: "bolder" means distinctive. Express a stronger point of view through hierarchy, pacing, proportion, copy, evidence, and one committed visual idea.
"Everything else stays" is a literal instruction. Touch only the named target. Do not restyle its neighbors, do not migrate the page to a new idea, do not add colors, fonts, radii, shadows, or system primitives the surface does not already own. If the existing system genuinely cannot express the direction, stop and ask the user directly to clarify what you cannot infer. before expanding it, naming the exact addition and the job it would do.
Operate + Read: "bolder" rarely means theatrics; those undermine trust. It means stronger hierarchy, clearer weight contrast, sharper information density, and more decisive prioritization. The amplification is in clarity, not drama.
## Why it reads flat
---
A section usually reads flat for reasons its neighbors have already solved. Look at what the rest of the page does that this section does not: the display type at full strength, the structural devices that carry meaning, the signature motif, the density and pacing, the specificity of the copy. A flat section is typically one that quietly opts out of the system's own strongest moves. The most reliable bolder pass brings the target up to the expressive level its neighbors already reach, in the system's own vocabulary rather than a new one.
## Assess Current State
## The amplification
Analyze what makes the design feel too safe or boring:
- **Amplify what the system already owns.** Reuse its motif and its type scale at full strength, turned up for this section rather than invented for it. The bolder version should look more like the same brand, not less.
- **Let the content carry the weight.** Flat copy makes a flat design, and no amount of size fixes a generic claim. Make every word specific enough to earn its place, and let the section's real evidence do the work that a decorative addition would otherwise fake.
- **Commit, then clarify.** Half-measures read as noise. Make the one decisive move completely, then quiet everything around it so the move is legible. If every element got louder, the section got flatter.
- **Give it its own rhythm.** The target should read as a peak in the scroll, a shift in density or pace from what surrounds it, not simply more of the same.
1. **Identify weakness sources**:
- **Generic choices**: The page could belong to any product in the category.
- **Timid scale**: Everything is medium-sized with no clear lead.
- **Low contrast**: Important and supporting elements have similar visual weight.
- **Static**: The surface has no meaningful moment of emphasis.
- **Predictable**: The composition follows a default pattern without a point of view.
- **Flat hierarchy**: Nothing stands out or commands attention.
## The skeleton test
2. **Understand the context**:
- What is the brand personality?
- What is the purpose of this surface?
- Who is the audience?
- What design system, tokens, components, and visual conventions already exist?
Strip the copy out of your planned section and study the bare structure. Does the skeleton still say what this section is and why it matters, through hierarchy and the system's devices alone? If it only works once the words return, the boldness is in the text size, not the design. A placeholder for an image or artifact names a job, an anchor and a piece of evidence, not a cue to drop in a decorative photo; fill that job with whatever the subject actually has.
If any of these are unclear from the codebase, ask the user directly to clarify what you cannot infer.
## Before you finish
**CRITICAL**: "Bolder" does not mean chaotic or garish. It means distinctive, memorable, and confident. Think intentional drama, not random noise.
- Everything outside the named target is unchanged.
- No new color, font, or system primitive appeared without being asked for.
- The conventions the section carried, including anything that drives an action, still work the same way.
- The section is unmistakably the same brand, only more sure of itself.
**WARNING - AI SLOP TRAP**: Review ALL the DON'T guidelines from the parent impeccable skill (already loaded in this context) before proceeding. Bold means distinctive, not "more effects."
## Design-System Lock
If the project has `DESIGN.md`, tokens, theme variables, or established component styles, treat that system as the boundary. Make the existing language stronger before adding new language.
Do not invent new colors, gradients, radii, shadows, fonts, decorative backgrounds, or effects just because the request says "bolder." A bolder pass should usually change emphasis, proportion, rhythm, density, contrast, copy, artifact specificity, and layout relationships while staying inside the documented system.
If the existing system is genuinely too limited to express the bolder direction, stop and ask the user before expanding it. Name the exact additions, the role each would play, and why the current system cannot do the job. If the user approves expansion, update the design system or tokens alongside the implementation.
## Plan Amplification
Create a strategy to increase impact while maintaining coherence:
- **Focal point**: Pick one thing the viewer should remember, then make the rest support it.
- **System levers**: Identify which existing tokens, components, layout patterns, and copy structures can carry more weight.
- **Risk budget**: Decide how far the surface can push while still feeling like the same product or brand.
- **Hierarchy amplification**: Increase contrast between primary, secondary, and tertiary content instead of making every element louder.
**IMPORTANT**: Bold design must still be usable. Impact without function is just decoration.
## Amplify the Design
Systematically increase impact through intention, not a menu of effects:
### Typography Amplification
- Strengthen the existing type hierarchy before changing typefaces.
- Make important text meaningfully more dominant, and make supporting text quieter.
- Use weight, measure, spacing, and line breaks to sharpen the point of view.
- Add or replace fonts only after user-approved design-system expansion.
### Color Amplification
- Use the existing palette more decisively before adding colors.
- Shift the proportion, placement, and contrast of documented colors to clarify meaning.
- Treat any new color, gradient, or tint ramp as a design-system expansion that requires user approval.
- Keep color tied to hierarchy, state, or brand meaning; do not use it as surface decoration.
### Spatial Amplification
- Change proportion, density, alignment, and sequencing so the composition has a stronger point of view.
- Create clearer contrast between dense evidence and open breathing room.
- Let layout express priority and narrative order before adding ornament.
- Preserve responsive behavior and avoid text overflow at every breakpoint.
### Surface Amplification
- Use existing surface, border, radius, and shadow rules more deliberately.
- Remove timid half-measures: either give an element a clear role or simplify it.
- Add texture, depth, illustration, or decorative treatments only when already established by the system or explicitly approved.
- Make real product artifacts, imagery, data, or copy carry attention before reaching for effects.
### Motion & Animation
- Design one meaningful moment of emphasis when motion genuinely supports the point.
- Make interaction feedback feel more decisive without becoming distracting.
- Keep transitions smooth and intentional.
- **Bolder != scroll-fade-rise on every section.** That's the saturated AI default, the opposite of bold.
### Composition Boldness
- Make the dominant idea unmistakable.
- Use layout tension, sequencing, contrast, and restraint to create a stronger read.
- Let the page's structure communicate priority before adding decorative layers.
- If every element is louder, the composition is not bolder; it is flatter.
**NEVER**:
- Add undocumented design-system primitives without user approval
- Add effects randomly without purpose
- Hide weak hierarchy behind decoration
- Sacrifice readability for aesthetics
- Make everything bold; contrast is the point
- Ignore accessibility
- Overwhelm with motion
- Copy trendy aesthetics blindly
## Verify Quality
Ensure amplification maintains usability and coherence:
- **System-faithful**: Did the pass make the existing design language stronger before adding anything new?
- **No undocumented drift**: Are new colors, gradients, shadows, radii, fonts, and effects either absent or explicitly approved and documented?
- **NOT AI slop**: Does this look like every other AI-generated "bold" design? If yes, start over.
- **Still functional**: Can users accomplish tasks without distraction?
- **Coherent**: Does everything feel intentional and unified?
- **Memorable**: Will users remember this experience for the intended reason?
- **Performant and accessible**: Does the result stay fast, readable, responsive, and WCAG-conscious?
**The test**: If you showed this to someone and said "AI made this bolder," would they believe you immediately? If yes, you've failed. Bold means distinctive, not "more AI effects."
When the result feels right, hand off to `/impeccable polish` for the final pass.
When the target holds its own without pulling the page apart, hand off to `/impeccable polish` for the final pass.

# Live generation worker
You generate reviewable variants for an existing interface. The supervisor owns all filesystem writes, publication, cancellation, and recovery. Return only the requested structured output.
## Identity and quality
- Preserve the existing product identity by default: palette roles, available fonts, component roles, copy, semantics, accessibility, and public APIs.
- Treat DESIGN.md as visual authority and PRODUCT.md as strategy/voice authority.
- Define one shared identity lock and distinct design axes before authoring the first variant.
- Make each variant independently shippable. Vary hierarchy, topology, typography, color commitment, density, or structural decomposition, not arbitrary decoration.
- Preserve short labels as readable units and avoid unnecessary wrapping at the supplied viewport.
- Prefer hierarchy, proportion, rhythm, and composition before adding nested chrome.
- Silently reject overflow, awkward wrapping, accidental compression, weak alignment, inaccessible states, and off-brand component treatments.
## Authoring contract
- The selected root is a complete replacement with exactly one top-level element.
- Preserve copy and dynamic relationships unless the user explicitly requests content changes.
- Never emit `data-impeccable-*` wrappers inside variant markup.
- Follow `event.scaffold.cssAuthoring` exactly. Fence every preview selector to its variant.
- Do not write source or project files. Return only paths and content permitted by the current output schema.
- Published variants are immutable. Never repeat or revise an earlier variant in a later phase.
- The staged artifact identifies the exact selected page/component. Inspect its real imports, shared layouts, styles, tokens, and route ownership with read-only tools whenever needed; do not assume a single-page project or guess from filenames.
## Progressive phases
- `first`: return variant 1 and the complete coherent plan. Defer parameters.
- `remainder`: return variants 2 through N together, following the stored plan, plus final parameter wiring CSS and the manifest for every variant. Do not change variant 1 or any default appearance.
- `params`: recovery only when all variants were durably published but their parameters were not. Return only parameter wiring CSS and the manifest.
- Parameters are coarse, meaningful axes already present in the designs. Tiny elements may have none; larger compositions usually expose two or three. Never exceed four per variant.
The supervisor runs the Impeccable detector before publication. On a repair turn, use judgment on every finding: fix real defects, but preserve contextually intentional design and detector false positives by returning the narrow `detectorWaivers` entry requested by the repair schema with a concrete reason. Never persist project ignore config or add inline ignore comments from this read-only worker. Publication proceeds only when every new finding was fixed or explicitly waived.

Do **not** use `--stream` on Cursor: incremental stdout notify is slower in practice than exit-based notify (~5s vs sub-second in testing).
- **Codex**: run the poll in the **foreground** (blocking shell; not a background task, not a subagent). Codex background exec sessions do not reliably surface poll stdout back into the conversation at the moment events arrive, so a "fire-and-forget" background poll will stall live mode.
- **Codex**: `live.mjs` starts a dedicated app-server generation lane by default and returns its exact persistent foreground control command. Run that `--stream` command once in a yielded foreground exec session; do not suffix it with `&`, restart it after each event, or launch an overlapping poll. The yielded shell remains alive while the model handles Steer, manual Apply, or carbonize through separate tool calls; after the model posts `--reply`, the same stream resumes polling automatically. Keep the task open until Live exits. The stream dynamically adds generation events only if the dedicated worker fails or exits. When the worker is explicitly disabled or unavailable, preserve the portable one-shot foreground path and delegate to the low-effort `impeccable_live_generator` agent with a compact handoff. Do not paste this full reference into the handoff.
- **Other harnesses**: one-shot foreground unless you know stdout reliably returns to this session when a shell exits.
Generation delivery policy:
- **Default (Claude Code, Cursor, and other harnesses):** keep the established atomic single-edit delivery unless that harness has independently demonstrated that progressive tool calls are faster and reliable. This avoids trading model latency for extra tool-call latency on harnesses with different streaming behavior.

Server restart rule: start `live-server.mjs` again, then poll. Startup requeues unacknowledged pending events from the journal, so do not ask the user to click Go again unless `live-resume.mjs` says no active session exists.
### Dedicated Codex worker
Codex uses a Live-owned persistent app-server supervisor instead of using the desktop task as the poll supervisor:
```bash
node .github/skills/impeccable/scripts/live.mjs
```
Activation is process-local: the worker is enabled by default only when the process carries a Codex runtime signal, so a committed setting cannot switch another harness onto Codex. Set `IMPECCABLE_LIVE_CODEX_WORKER=0` to force the portable foreground path. Project config may tune delivery or select the explicit `fast` profile without enabling the worker in another harness:
```json
{
"experimentalCodexWorker": {
"profile": "quality",
"delivery": "progressive"
}
}
```
The app-server worker is **default-on in Codex and Codex-only**. Claude, Gemini, Cursor, and every other harness keep the portable foreground/atomic behavior. Before detaching anything, Live resolves the configured Codex executable using the same explicit-path/PATH rules as Node spawn. A missing CLI becomes an immediate, durable foreground fallback with setup guidance instead of a misleading prewarm state. Otherwise Live records the worker as `starting` and returns immediately, so app-server initialization overlaps page/dev-server startup. Run only the returned foreground control poll. It checks the owned worker process every two seconds and safely restores generation/accept/discard leasing if startup, authentication, model selection, or the worker process fails. Dedicated-worker leases expire after 15 seconds, so a hard process loss cannot strand browser work behind the portable ten-minute lease.
```bash
node .github/skills/impeccable/scripts/live-poll.mjs --stream --types=steer,manual_edit_apply,carbonize_cleanup,exit --codex-worker-fallback
```
The supervisor launches its own `codex app-server --stdio` process, dynamically prefers the strongest visible general model (currently GPT-5.6 Sol), and uses medium reasoning. The optional `fast` profile retains Spark/mini selection and low reasoning for controlled comparisons. It creates a dedicated Impeccable-owned thread and persists only that id in `.impeccable/live/codex-worker.json`; it never lists, resumes, steers, or writes to the desktop task. A crash reconnect may resume that id only when the ownership marker and project cwd both match. Clean Live exit interrupts the active turn, archives the dedicated thread, and stops app-server.
The first generation turn in a worker task attaches the installed Impeccable skill as a native app-server skill input and resolves inherited/monorepo PRODUCT.md and DESIGN.md through the same context loader as the foreground skill. Each generation supplies the exact selected source artifact, event, scaffold, page URL, and action reference. The persistent read-only thread decides which imports, route layouts, styles, tokens, or shared components it needs to inspect; no lexical source-neighborhood heuristic stands in for repository understanding. Annotated requests attach `screenshotPath` as a real high-detail local image instead of a JSON path.
One persistent app-server thread performs both normal generation turns so identity, repository discoveries, the variant plan, and skill guidance remain coherent. Model turns run read-only and return structured staged-artifact files. Before publication, the supervisor runs the Impeccable detector against the staged candidate, compares it with the pre-existing baseline, and asks the same thread for one repair when new findings appear. The repair must fix real defects or explicitly classify contextually intentional/false-positive findings with narrow, reasoned per-candidate waivers; only findings left neither fixed nor waived block publication. Existing project detector ignores are honored by the scan, while the read-only worker never persists new config or inline suppressions. The supervisor then validates paths and publishes exclusively through the generation publisher's epoch/source-hash/immutable-prefix fence. Source-wrapper sessions use an isolated preview under `.impeccable/live/previews/`; the true source stays byte-identical until Accept. Progressive variant 1 is immediately reviewable; variants 2 through N and their parameters arrive together from turn two. Accept/Discard interrupts the active app-server turn, while the durable generation fence rejects any late completion that still races cancellation.
Controls:
```bash

Model and binary overrides are `IMPECCABLE_LIVE_CODEX_PROFILE`, `IMPECCABLE_LIVE_CODEX_MODEL`, `IMPECCABLE_LIVE_CODEX_EFFORT`, and `IMPECCABLE_CODEX_PATH`. `delivery: "atomic"` retains the one-turn publication control. Steer, manual Apply, carbonize cleanup, and Exit remain on the high-judgment foreground control lane; the server's type filter prevents either lane from leasing the other's events.

## Decide, then build
Sketch three directions in one line each before choosing: they must differ in concept, not in polish. If the direction you'd instinctively ship is the one any competent studio would also reach for, it is the default wearing your name; pick the direction that is most specific to this subject and still serves the mode.
Derive the concept with this procedure, recording each step in your reasoning before the next begins. One: state the product's unique mechanism in one sentence, the thing competitors cannot truthfully claim. Two: competitive analysis; describe the page this category always ships, and the counter-position page a contrarian ships, and treat both structures as off the table. Three: from the audience's world and the subject's cultural home, list seven concrete materials, objects, documents, or rituals they know by heart, each with one line on why it resonates and can carry the mechanism, ordered by resonance. Four: run `node .github/skills/impeccable/scripts/concept-seed.mjs` and follow what it prints: it assigns which candidate to build (your top-ranked candidate is what every run would ship; a single ranking is deterministic, so the dice come from outside) and supplies challenger forms to weigh against your list on exactly two axes, audience identification and product clarity. Five: the chosen form supplies the page's structure, reading order, and component conventions; the product supplies every fact. Commit every atom: nav, buttons, inputs, and links are rebuilt in the form's vocabulary, and a stock component inside a committed form is a lapse. The form has its own native arrangement; borrow its skeleton, not just its clothes. Land the first build fully committed; committing is the hard part, and the passes that follow exist to make the committed thing clear and effective, never to dilute it. Conversion conventions live inside the form's own vocabulary: a hero that hooks in one line, a visible primary action, a legible reading order. The chosen form also dictates the first viewport's geometry: render the form at the scale it has in life, edge to edge when that is its nature; embedding it as a panel inside a standard marketing layout forfeits it. Cinematic full-bleed openings, intentionally divergent grids, and color drenched across whole regions are in bounds whenever the form calls for them; on an unattended build, the safe layout is the risk. The form has native motion, what it does in life between states; give the page that motion once, orchestrated, rather than scattered hover effects.
Then state the chosen direction as a contract, written as a comment block at the top of the artifact (invisible to visitors, binding for you): the concept in one line; what a visitor would describe an hour after one viewport; why this page could not be the modal competitor page; the signature; and what the first viewport does instead of a generic header. If any answer is missing or reads like a mood, the direction isn't decided yet. The build is judged against this contract; delivering different pixels than the contract promises is a defect on whichever side is weaker. When a user can respond and the work is substantial, pause there for confirmation; when the harness has native image generation, follow [codex.md](codex.md)'s mock flow before code. When no user can respond, record the decision in your reasoning and proceed without pausing. Either way the decision comes first; code that precedes a direction is the template reflex in motion.

## Plan, self-check, build
Plan a compact token system in your reasoning: palette, type, layout concept in one sentence, and a **signature**: the one element this surface will be remembered by, drawn from the subject's world. A signature carries weight: sized and placed so the page organizes itself around it. The layout has exactly two legitimate sources: the concept, or the content's own structure. The category's habitual skeleton is neither, and assembling the usual sections in the usual order after choosing a concept is the same reflex the palette rule breaks, expressed in structure. Then audit the plan: work through what you'd produce for a similar brief from another client, and wherever the two plans converge (same palette family, same face, same skeleton), that part is your generic default, not a choice. Revise it, then build, deriving every color and type decision from the revised plan.
**The first viewport is a thesis, not a header.** The visitor should meet the concept doing its job immediately: the work itself, the product working, the content answering, the task at hand. Generic chrome around a generic promise is the template answer; earn it or replace it. The memory test: if someone left after one viewport, what would they describe an hour later? If the honest answer is a mood ("clean", "tasteful"), the concept hasn't committed yet.
**Pace the scroll like a studio.** The scroll is a rhythm, not a stack: alternate full-bleed bands of the palette, vary the treatment from section to section inside the one system (a dense passage earns a quiet one, a graphic section earns a typographic one), ground at least one section in the signature motif as texture, and end anchored by a real close. One spacing rhythm throughout, kept like a promise: sections breathe in large, legible beats, and the space above a heading always exceeds the space below it. A page whose every section wears the same weight and density reads as monotone no matter how strong the concept.
**The first viewport is a thesis, not a header.** The visitor should meet the concept doing its job immediately: the work itself, the product working, the content answering, the task at hand. Generic chrome around a generic promise is the template answer; earn it or replace it. The composition is derived the same way the palette is: if a neighboring product could ship the same arrangement of the same blocks, the viewport isn't composed yet. The memory test: if someone left after one viewport, what would they describe an hour later? If the honest answer is a mood ("clean", "tasteful"), the concept hasn't committed yet.
**Everything bold, nothing bland.** Bold is not decoration and not clutter; it is commitment to the concept, carried through every section. Commitment takes whatever form the concept and the mode demand: maximal or severely clean, drenched in color or nearly monochrome, copy so precise it stings, the product demonstrating itself, or a system so exact it feels inevitable (a decisive typographic voice, one owned accent, an unmistakable rhythm). A spare page built on one uncompromising idea is bold; a busy page of tasteful defaults is bland. The signature is where the concept peaks, not the only place it lives; cut anything that neither advances the concept nor serves the visitor's mode. Polish is the floor, not the point: when torn between refined and committed, commit.
**Prove, don't claim.** A surface earns belief by showing its subject doing its job: the interface at work, the mechanism dramatized, the content delivering, specifics a competitor couldn't copy-paste. The visitor should understand by looking, before reading a word. Sections that restate a claim in different words add length, not substance.

The visitor should understand by looking, before reading a word.

## Finish like a studio
Look at what you built the way a design lead would, with whatever eyes the harness gives you (browser, screenshot tool, or reading the code cold): major sections individually on long pages, mobile and desktop at minimum. Write an honest critique against the brief and the stated direction, patch material defects, and re-inspect; don't invent defects to demonstrate diligence. Then verify against SKILL.md's craft floor and run the detector; a bold page that ships mechanical defects is not done, and neither is a polished page missing something the brief asked for.
When the harness can run a separate agent, the review above belongs there, not here: hand the reviewer the artifact path, its direction contract, and the detector command, and have it return a short list of material fixes; apply them and finish. A fresh reader catches what the builder's own eyes slide past, and the build thread stays spent on building.

/**
* Concept-seed picker: the dice half of the new-work concept procedure.
*
* The model derives a grounded shortlist of candidate FORMS from the
* audience's world and the subject's cultural home (see
* reference/new-work.md). Left alone, it then always builds its #1 —
* and a single model's resonance ranking is deterministic, so every run
* in a category ships the same one or two concepts. Measured: 30/35
* identical concepts across 16 prompt framings; the model cannot roll
* its own dice.
*
* This script rolls them from outside, the same trick that made the
* palette seed work:
* - BUILD INDEX (2-5): which entry of the model's own resonance-ordered
* shortlist to build. The dice never choose an ungrounded ingredient;
* they only refuse the argmax rut. (Index 1 is excluded: that's the
* concept every run would ship anyway.)
* - CHALLENGERS (3): outside forms from concept-ingredients.json, weighed
* against the derived candidates on exactly two axes — audience
* identification and product clarity. They win only when they beat the
* grounded list; measured behavior is that they lose to strong cultural
* material and win over thin categories, which is the intended shape.
*
* Usage:
* node scripts/concept-seed.mjs # roll at random
* node scripts/concept-seed.mjs --from <key> # deterministic (hash key)
*
* Env vars:
* IMPECCABLE_CONCEPT_SEED — same as --from; for reproducible eval runs.

category would ship; the assignment exists to refuse that rut, not to

// this is a message, not a judge. It fires at most once per file per session
// (a `contractAudited` flag on the session cache entry, the same state the
// deep pass uses for finding dedupe) and rides the Stop pass's existing
