--- name: design-rationale-writer description: "Converts bullet-point design decisions into clear, business-framed rationale for stakeholder presentations or async updates — connecting each creative choice to user needs, brand strategy, and business outcomes in language non-designers trust. Use when defending a design direction, writing up creative decisions for leadership, preparing presentation talking points, or explaining why a design looks the way it does to non-design stakeholders." argument-hint: "[design-decisions] [audience]" allowed-tools: ["Read"] --- # Design Rationale Writer ## Purpose Turn a designer's shorthand decision notes into structured, business-framed rationale that non-design stakeholders can read, believe, and repeat — so creative work gets approved on its merits instead of dying in subjective "I just don't love it" feedback loops. ## When to Use Invoke this skill when the user asks to: - Write up the reasoning behind a design direction for leadership or clients - Prepare talking points to defend design choices in a review meeting - Explain why a logo, layout, color, or UI decision was made to non-designers - Turn bullet-point design notes into a polished async Slack or Notion update - Justify a creative decision that's getting subjective pushback - Document design rationale for a case study or handoff ## Inputs Required Before starting, collect: - **Design decisions**: The choices made, in whatever bullet/shorthand form the designer has (e.g., "went warmer palette, dropped the drop shadows, single CTA") - **What was designed**: The artifact — brand identity, landing page, app screen, packaging, campaign, etc. - **Audience**: Who reads this — executives, clients, cross-functional PMs, marketing lead - **Business goal**: What this design is meant to achieve (conversion, trust, differentiation, clarity, launch readiness) - **Constraints or context**: Brand guidelines, prior feedback, technical limits, or the problem the design solves - **Delivery format**: Presentation talking points / async written update / formal doc If business goal is missing, infer the most likely one from the artifact type and note the assumption. If audience is missing, default to cross-functional stakeholders (non-designers who care about outcomes, not craft). ## Instructions ### Step 1: Translate Each Decision Through the Rationale Chain For every design decision provided, run it through this four-link chain — this is the core mechanism that turns aesthetic choices into business arguments: 1. **The decision** (what was done) — stated plainly 2. **The reason** (why, in design terms) — the craft logic 3. **The user/business connection** (so what) — how it serves the person using it or the goal 4. **The outcome** (what it produces) — the measurable or observable result Example transformation: - Shorthand: "dropped the drop shadows" - Rationale: "We removed the drop shadows on cards and buttons. Flat surfaces read as more modern and reduce visual noise, which lets the primary action stand out. Fewer competing visual cues means users spot the 'Get Started' button faster — supporting the goal of a cleaner path to signup." Never stop at link 2. Non-designers don't need to be convinced the choice is *pretty* — they need to see it serves the *goal*. ### Step 2: Frame in the Audience's Language Rewrite craft vocabulary into stakeholder vocabulary: - "Whitespace / negative space" → "breathing room that keeps attention on the offer" - "Visual hierarchy" → "the order people notice things in" - "Kerning / leading / type scale" → "readability" or "how easy the text is to scan" - "Reduced the palette" → "tightened the color system so the brand feels consistent" - "Grid alignment" → "structure that makes the page feel trustworthy and organized" Keep one or two craft terms *if* the audience is designers or a mixed group — otherwise translate everything. Match register: executives want outcomes and confidence; clients want reassurance and clarity; PMs want tradeoffs and reasoning. ### Step 3: Lead With the Strategic Frame Open with 1–2 sentences that name the problem the design solves and the goal it serves — before any individual decision. This positions the rationale as strategy, not taste. Stakeholders should understand *what you were trying to accomplish* before they hear *what you did*. ### Step 4: Handle Tradeoffs and Rejected Alternatives Where relevant, acknowledge what was considered and set aside. This preempts the "why didn't you just do X" question and signals rigor: - "We tested a bolder red but it competed with the brand's existing warning states, so we held the accent color to the CTA only." - State the tradeoff honestly — never pretend a choice was cost-free. ### Step 5: Close With Confidence, Not a Question End by restating how the design serves the goal — a summary the reader can repeat to *their* stakeholders. Do not end with "let me know your thoughts!" unless the delivery format is an async update inviting feedback, in which case pose one specific, decision-oriented question rather than an open invitation to critique. ## Output Format - **Structure**: Strategic frame → decision-by-decision rationale → tradeoffs (if any) → confident close - **Length**: 250–500 words for async updates; 400–700 words for presentation/doc format - **Format**: Prose for narrative sections; each design decision as a short paragraph or a labeled block (**Decision → Rationale**), matched to the delivery format requested - **Sections**: The Goal / What We Were Solving → The Decisions (one block per decision) → What We Considered and Set Aside (if applicable) → How This Serves the Goal - **Tone**: Confident, plainspoken, outcome-first. The voice of a designer who respects the reader's time and speaks their language — never defensive, never jargon-heavy, never apologetic about the work. ## Quality Checklist Before delivering output, verify: - [ ] Every design decision provided is addressed — none dropped or merged silently - [ ] Each decision runs the full chain to a user or business outcome (link 4), not just craft logic (link 2) - [ ] No unexplained design jargon remains for a non-design audience - [ ] The opening names the goal or problem before listing any decisions - [ ] The close is a confident restatement, not an open "thoughts?" plea (unless async feedback was requested) - [ ] Length matches the requested delivery format ## Notes - The single most common failure in design rationale is stopping at "because it looks cleaner." Craft reasoning convinces other designers; outcome reasoning convinces the people who approve budgets. - For subjective pushback ("I just don't love the color"), the rationale should reframe the conversation from preference to purpose — give the stakeholder a *goal* to evaluate against instead of their gut. - Async Slack/Notion versions should be scannable: bold the decision, keep each rationale to 2–3 sentences, and skip the formal doc framing. - When the design is genuinely a judgment call with no hard data, say so honestly and anchor it to brand strategy or precedent — invented metrics erode trust faster than an honest "this is a craft judgment aligned with our brand direction." --- ## How to use this skill This file is a Claude Code skill in [Anthropic's standard format](https://docs.anthropic.com/en/docs/claude-code/skills) — markdown with YAML frontmatter at the top. **Installing in Claude Code:** - `~/.claude/skills//SKILL.md` — auto-loads in every session anywhere on your machine (recommended for skills you'll use across multiple projects) - `/.claude/skills//SKILL.md` — auto-loads only when working in that project (recommended for project-specific skills) Restart Claude Code or open a new session to register. **Using in Claude.ai, ChatGPT, Gemini, or other AI tools:** 1.
