Design System Architecture Decisions Record with Claude Desktop
Document design system decisions that last. Use Claude Desktop to create Architecture Decision Records that explain the why behind every component choice.
Why ADRs for Design Systems?
Design systems accumulate decisions over time: why this spacing scale, why these breakpoints, why this component API, why this color naming convention. Six months later, nobody remembers WHY — they only know WHAT exists.
When someone proposes changing a decision, the team can't evaluate whether the change is good because they've lost the original context. They either reject changes reflexively ('we've always done it this way') or accept them without understanding the trade-offs.
Architecture Decision Records (ADRs) solve this by documenting decisions as they're made: the context, the options considered, the decision, and the consequences. Originally from software architecture, ADRs work beautifully for design systems.
Claude Desktop is uniquely suited for this task: it can analyze your existing design system, ask clarifying questions about decisions, and generate structured ADR documents that capture the full context.
ADR Structure for Design
Each ADR follows a standard structure adapted for design decisions.
Title and Status
A descriptive title ('ADR-007: Use 8px spacing grid') and status (Proposed, Accepted, Superseded). Status tracking prevents confusion about which decisions are current.
Context
Why is this decision being made now? What problem exists? 'Our spacing is inconsistent across components. Some use 4px base, others 5px, others arbitrary values. This causes visual discord and makes responsive design unpredictable.'
Options Considered
List 2-3 alternatives that were evaluated. For each: brief description, pros, and cons. '4px grid (more granular, complex), 8px grid (simpler, occasionally constraining), arbitrary (flexible, inconsistent).'
Decision and Consequences
The chosen option and its expected impact. 'We chose 8px grid. Consequence: simpler to maintain, but some fine-grained adjustments require half-step (4px) exceptions documented per-component.'
Using Claude Desktop for ADRs
Decision Interview
Describe the decision to Claude: 'We need to decide on a spacing system for our design system.' Claude asks clarifying questions about your constraints, team size, existing patterns, and goals. The conversation naturally surfaces the decision context.
Options Analysis
Ask Claude to analyze trade-offs: 'Compare 4px vs 8px spacing grids for a design system used by 15 designers and 30 engineers.' Claude provides structured analysis considering factors you might not think of (developer experience, CSS output size, responsive scaling).
ADR Generation
After the conversation, ask Claude to 'format this decision as an ADR.' Claude generates a structured document from the discussion, capturing context and reasoning that would otherwise be lost.
Historical ADR Recovery
For existing decisions without documentation: 'Our design system uses an 8px grid. Help me write a retrospective ADR that captures likely reasons for this decision based on common design system practices.' Claude infers reasonable context even for undocumented historical decisions.
Real ADR Examples
ADR-001: Color Token Naming Convention
Decision: Use semantic names (--color-primary, --color-surface) over raw names (--blue-500, --gray-100).
Context: Raw names break when themes change. 'blue-500' is meaningless in a dark theme where the primary color is purple.
ADR-003: Component API Pattern
Decision: Use compound components (Dialog.Root, Dialog.Content, Dialog.Close) over prop-heavy single components.
Context: Prop-heavy components become unmanageable past 10 props. Compound components are more verbose but more flexible and composable.
ADR-005: Animation Library Choice
Decision: Use Framer Motion over CSS animations.
Context: CSS animations are simpler but don't support layout animations or gesture-driven interactions. Framer Motion's bundle size is justified by the animation fidelity it enables.
Each ADR is 200-400 words. Short enough to read in 2 minutes, detailed enough to reconstruct the decision reasoning.
