Design Spec
Produce a design specification that maps a feature requirement to concrete design-system components, semantic tokens, and layout decisions — grounded in the business's brand language. Feeds directly into /lp-do-plan to raise confidence on UI tasks.
Operating Mode
ALLOWED: Read codebase, read docs, read theme tokens, create/update design spec docs, create/update brand language docs.
NOT ALLOWED: Write application code, modify components, change tokens, run builds. Design only — implementation is /lp-do-build's job.
When to Use
- New page, section, or significant UI component
- Visual refresh or rebrand work
- Any feature where fact-find flags
Design-Spec-Required: yes - When
/lp-do-planproduces low-confidence UI tasks (design decisions unmade) - Standalone brand language bootstrapping for a new business
Invocation
Fast Path
/lp-design-spec <feature-slug>
Expects docs/plans/<feature-slug>-fact-find.md to exist. Reads it, resolves the business unit, loads brand language, and begins spec creation.
Discovery Path
/lp-design-spec
No argument — presents the app-to-business mapping and asks what you're designing for.
Brand Bootstrap Mode
/lp-design-spec --bootstrap <BIZ-CODE>
Runs GATE-BD-07 pre-flight for the business unit without producing a feature design spec. Blocks and redirects to /lp-assessment-bootstrap <BIZ> if Brand Dossier is not Active. Use when checking brand-dossier readiness before onboarding a new business.

App-to-Business Resolution
Use businesses.json to resolve which business owns the target app, then locate:
- Brand language doc:
docs/business-os/strategy/<BIZ>/<YYYY-MM-DD>-brand-identity-dossier.user.md - Theme package:
packages/themes/<theme>/(mapped from app name) - Strategy context:
docs/business-os/strategy/<BIZ>/plan.user.md
Resolution: Read docs/business-os/strategy/businesses.json to resolve app → business unit → theme package. Do not use hardcoded mappings.
Workflow
Step 0: Context Resolution
- Identify the target app from the feature slug, fact-find, or user input.
- Resolve business unit via
businesses.json. - Load brand language doc. If it doesn't exist or Status ≠ Active:
- STOP. Emit GATE-BD-07 error (see Step 6).
- Do NOT offer to proceed without brand language.
- Load design profile from
packages/themes/<theme>/src/design-profile.ts— art-direction defaults and guidance for the brand. If the file does not exist, note that the theme has no design profile (use base defaults). - Load theme assets from
packages/themes/<theme>/src/assets.ts— available fonts, gradients, shadows, keyframes, brand colors. If the file does not exist or exports empty collections, note that the brand has no custom assets. - Load recipe catalogue from
packages/themes/<theme>/src/recipes.ts— branded surface compositions. If the file does not exist or is empty, note that no recipes exist yet. - Load theme tokens for the target app's theme package.
- Load fact-find if a feature slug was provided.
Step 1: Audience and Intent
Extract from brand language + fact-find:
- Who sees this? Target demographic, device context, usage scenario.
- What feeling? Brand personality (from brand language
## Voice & Tone). - What action? Primary CTA or user goal for this feature.
- Where in the app? Navigation context — is this a new page, a section in an existing page, a modal, a flow?
If any of these are unclear, ask the user. Do not assume.
Step 2: Current State Audit (Modification Only)
Skip this step for net-new pages/components.
For modifications to existing UI:
- Read the current component(s) being modified.
- Identify existing patterns: layout structure, component choices, token usage.
- Flag violations: arbitrary values, hardcoded colors, missing dark mode, accessibility gaps.
- Note reusable elements: what should be preserved vs. replaced.
Step 3: Component Map
Using the three-tier architecture (@acme/design-system → @acme/ui → app-level):
- List existing components that can be reused for this feature.
- Search
packages/design-system/src/for primitives/atoms/molecules. - Search
packages/ui/src/for domain components. - Search the target app's
src/components/for app-specific components.
- Search
- Identify gaps — components that don't exist yet.
- Decide layer for new components:
- Pure presentation, no domain logic →
@acme/design-system - Domain-specific (e-commerce, booking, etc.) →
@acme/ui - App-specific, unlikely to be shared → app-level
src/components/
- Pure presentation, no domain logic →
Output a component tree showing the composition hierarchy.
Step 4: Token Binding
For each visual property in the design, specify the exact semantic token:
| Property | Token | Value (from theme) | Rationale |
|---|---|---|---|
| Primary action bg | bg-primary |
hsl(6 78% 57%) |
Brand coral per brand language |
| Body text | text-fg |
(from base) | Default readable text |
| Card/surface-2 bg | bg-[hsl(var(--surface-2))] |
(from base) | Standard surface pattern |
| ... | ... | ... | ... |
Rules:
- Every color must map to a semantic token. No hex, no Tailwind palette colors.
- Reference
tools-design-systemskill for the canonical token list. - If a needed token doesn't exist, document it as a prerequisite (new token to add to theme package).
- Dark mode: verify every chosen token has a dark variant. Flag gaps.
Evidence requirement: For each token binding, cite the source file and token key where the value is defined (e.g., packages/themes/prime/src/tokens.ts → --color-primary). If no theme package exists, cite packages/themes/base/src/tokens.ts.
Step 5: Layout and Behavior
Define:
- Layout skeleton — CSS Grid/Flexbox structure with responsive breakpoints.
- Mobile-first. Specify
md:andlg:breakpoint changes. - Use design system spacing tokens only (
gap-4,p-6, etc.).
- Mobile-first. Specify
- Interaction states — hover, active, disabled, loading, error, empty.
- Map each state to token classes (e.g.,
hover:bg-primary-hover).
- Map each state to token classes (e.g.,
- Accessibility — WCAG AA minimum:
- Focus order (tab sequence).
- ARIA roles/labels for non-standard elements.
- Contrast compliance (note if any token combinations need checking).
- Touch target sizes (
min-h-11 min-w-11for interactive elements).
- Animation — only if required. Use
motion-safe:prefix. Respectprefers-reduced-motion.
Step 6: Brand Dossier Pre-flight (GATE-BD-07)
Before writing the design spec, verify the Brand Dossier is Active:
- Check
docs/business-os/strategy/<BIZ>/<YYYY-MM-DD>-brand-identity-dossier.user.mdexists AND frontmatterStatus: Active. - Check the strategy index
docs/business-os/strategy/<BIZ>/index.user.md— Brand Dossier row must showActive.
Gate result:
- PASS (Status == Active): proceed to Step 7.
- FAIL (missing or Status != Active): STOP immediately.
- Error:
GATE-BD-07: Brand Dossier must be Active before running design spec. - Remediation:
Run /lp-do-assessment-11-brand-identity --business <BIZ> to create the Brand Dossier, then have the operator promote it to Active before re-running /lp-design-spec. - Do NOT create or populate -brand-identity-dossier.user.md from within this skill. That is the job of
/lp-assessment-bootstrap.
- Error:
Note: GATE-BD-01 at S1 advance requires brand-dossier at Draft minimum. GATE-BD-07 here requires Active. The gap (Draft → Active) is the operator's responsibility before running lp-design-spec.
Exception — Base-System businesses: For businesses whose theme resolves to packages/themes/base/ and which have no customer-facing brand identity (e.g. PLAT, BOS, PIPE, XA), the Brand Dossier gate is waived. Use packages/themes/base/src/tokens.ts directly as the design reference. Add a note to the design spec frontmatter: Brand-Language: None — base theme (no brand dossier for this business). To confirm a business is base-system, read docs/business-os/strategy/businesses.json.
Step 7: Write Design Spec
Create docs/plans/<feature-slug>-design-spec.md using the template below.
Step 8: Brand Language Feedback Loop
After completing the spec, check if any design decisions made during this spec should feed back into the brand language doc:
- New pattern established (e.g., "cards in this app always use
rounded-lg shadow-sm") → add to brand language## Signature Patterns. - Token gap filled (e.g., new token added for this business) → update brand language
## Token Overrides. - Audience insight (e.g., fact-find revealed new demographic data) → update brand language
## Audience.
Only update with decisions that are stable and reusable, not one-off feature specifics.

Quality Checks
- Every color references a semantic token — zero arbitrary values
- Component map distinguishes reused vs. new, with correct package layer
- Layout specifies all three breakpoints (mobile, tablet, desktop)
- Dark mode addressed for every token binding
- Accessibility section is non-empty with concrete ARIA/focus/contrast items
- Brand Dossier Active (GATE-BD-07 pre-flight passed: Status == Active in -brand-identity-dossier.user.md)
- Token bindings match actual values in theme package (not invented)
- Prerequisites list is complete — no hidden assumptions for
/lp-do-plan -
Surface-Modefield is set in frontmatter with justification in Context section - Design Character section populated from design profile (or noted as absent)
- Available Assets section populated from assets.ts (or noted as absent)
- Applicable Recipes section populated from recipes.ts filtered by surface mode (or noted as empty)
Integration
With /lp-do-fact-find
When a fact-find classifies a feature as UI-heavy, it should add to its output:
Design-Spec-Required: yes
This signals that /lp-design-spec should run before /lp-do-plan.
With /lp-do-plan
Plan reads the design spec and uses it to:
- Pre-populate
Affectslists with component file paths from the component map - Set higher confidence on UI tasks (design decisions already made)
- Create concrete validation contracts referencing the spec's token bindings
- Generate prerequisite tasks for missing tokens or components
With /lp-do-build
During build, the design spec serves as a reference:
- Exact token classes to use (no guessing)
- Component composition tree to follow
- Accessibility requirements to implement and test
With Brand Language Docs
Reads from: docs/business-os/strategy/<BIZ>/<YYYY-MM-DD>-brand-identity-dossier.user.md
Writes back to: Same file, when stable new patterns emerge (Step 8).
This creates a virtuous cycle: each design spec strengthens the brand language, which makes future specs faster and more consistent.
Hand-off Messages

GATE-BD-07 Blocked (Brand Dossier not Active)
GATE-BD-07: Brand Dossier must be Active before running design spec.
Current Status:
docs/business-os/strategy/{BIZ}/<YYYY-MM-DD>-brand-identity-dossier.user.mdis missing or Status ≠ Active.Remediation: Run
/lp-do-assessment-11-brand-identity --business {BIZ}to create the Brand Dossier, then promote to Active before re-running/lp-design-spec.
Red Flags (Invalid Run)
- Spec contains arbitrary color values (
[#hex],bg-red-500, etc.) - Component map places domain components in
@acme/design-system - No accessibility section or "N/A" without justification
- Brand language not consulted and no explicit opt-out rationale
- Token bindings reference tokens that don't exist in the theme package without noting them as prerequisites
- Layout section missing responsive breakpoints
