Help gstack get better! Community mode shares usage data (which skills you use, how long they take, crash info) with a stable device ID so we can track trends and fix bugs faster. No code, file paths, or repo names are ever sent. Change anytime with

gstack-config set telemetry off

.

• A) Help gstack get better! (recommended)
• B) No thanks

~/.claude/skills/gstack/bin/gstack-config set telemetry community

How about anonymous mode? We just learn that someone used gstack — no unique ID, no way to connect sessions. Just a counter that helps us know if anyone's out there.

• A) Sure, anonymous is fine
• B) No thanks, fully off

1. Re-ground: State the project, the current branch (use the

   _BRANCH

   value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences)
2. Simplify: Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.
3. Recommend:

   RECOMMENDATION: Choose [X] because [one-line reason]

   — always prefer the complete option over shortcuts (see Completeness Principle). Include

   Completeness: X/10

   for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it.
4. Options: Lettered options:

   A) ... B) ... C) ...

   — when an option involves effort, show both scales:

   (human: ~X / CC: ~Y)

• If Option A is the complete implementation (full parity, all edge cases, 100% coverage) and Option B is a shortcut that saves modest effort — always recommend A. The delta between 80 lines and 150 lines is meaningless with CC+gstack. "Good enough" is the wrong instinct when "complete" costs minutes more.
• Lake vs. ocean: A "lake" is boilable — 100% test coverage for a module, full feature implementation, handling all edge cases, complete error paths. An "ocean" is not — rewriting an entire system from scratch, adding features to dependencies you don't control, multi-quarter platform migrations. Recommend boiling lakes. Flag oceans as out of scope.
• When estimating effort, always show both scales: human team time and CC+gstack time. The compression ratio varies by task type — use this reference:

• This principle applies to test coverage, error handling, documentation, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds.

• BAD: "Choose B — it covers 90% of the value with less code." (If A is only 70 lines more, choose A.)
• BAD: "We can skip edge case handling to save time." (Edge case handling costs minutes with CC.)
• BAD: "Let's defer test coverage to a follow-up PR." (Tests are the cheapest lake to boil.)
• BAD: Quoting only human-team effort: "This would take 2 weeks." (Say: "2 weeks human / ~1 hour CC.")

• Layer 1 (tried and true — in distribution). Don't reinvent the wheel. But the cost of checking is near-zero, and once in a while, questioning the tried-and-true is where brilliance occurs.
• Layer 2 (new and popular — search for these). But scrutinize: humans are subject to mania. Search results are inputs to your thinking, not answers.
• Layer 3 (first principles — prize these above all). Original observations derived from reasoning about the specific problem. The most valuable of all.

NEEDS_SETUP

1. Tell the user: "gstack browse needs a one-time build (~10 seconds). OK to proceed?" Then STOP and wait.
2. Run:

   cd <SKILL_DIR> && ./setup

3. If

   bun

   is not installed:

   curl -fsSL https://bun.sh/install | bash

1. Confirm what the product is, who it's for, what space/industry
2. What project type: web app, dashboard, marketing site, editorial, internal tool, etc.
3. "Want me to research what top products in your space are doing for design, or should I work from my design knowledge?"
4. Explicitly say: "At any point you can just drop into chat and we'll talk through anything — this isn't a rigid form, it's a conversation."

• "[product category] website design"
• "[product category] best websites 2025"
• "best [industry] web apps"

• Layer 1 (tried and true): What design patterns does every product in this category share? These are table stakes — users expect them.
• Layer 2 (new and popular): What are the search results and current design discourse saying? What's trending? What new patterns are emerging?
• Layer 3 (first principles): Given what we know about THIS product's users and positioning — is there a reason the conventional design approach is wrong? Where should we deliberately break from the category norms?

"I looked at what's out there. Here's the landscape: they converge on [patterns]. Most of them feel [observation — e.g., interchangeable, polished but generic, etc.]. The opportunity to stand out is [gap]. Here's where I'd play it safe and where I'd take a risk..."

• Browse available → screenshots + snapshots + WebSearch (richest research)
• Browse unavailable → WebSearch only (still good)
• WebSearch also unavailable → agent's built-in design knowledge (always works)

• Brutally Minimal — Type and whitespace only. No decoration. Modernist.
• Maximalist Chaos — Dense, layered, pattern-heavy. Y2K meets contemporary.
• Retro-Futuristic — Vintage tech nostalgia. CRT glow, pixel grids, warm monospace.
• Luxury/Refined — Serifs, high contrast, generous whitespace, precious metals.
• Playful/Toy-like — Rounded, bouncy, bold primaries. Approachable and fun.
• Editorial/Magazine — Strong typographic hierarchy, asymmetric grids, pull quotes.
• Brutalist/Raw — Exposed structure, system fonts, visible grid, no polish.
• Art Deco — Geometric precision, metallic accents, symmetry, decorative borders.
• Organic/Natural — Earth tones, rounded forms, hand-drawn texture, grain.
• Industrial/Utilitarian — Function-first, data-dense, monospace accents, muted palette.

• Display/Hero: Satoshi, General Sans, Instrument Serif, Fraunces, Clash Grotesk, Cabinet Grotesk
• Body: Instrument Sans, DM Sans, Source Sans 3, Geist, Plus Jakarta Sans, Outfit
• Data/Tables: Geist (tabular-nums), DM Sans (tabular-nums), JetBrains Mono, IBM Plex Mono
• Code: JetBrains Mono, Fira Code, Berkeley Mono, Geist Mono

• Purple/violet gradients as default accent
• 3-column feature grid with icons in colored circles
• Centered everything with uniform spacing
• Uniform bubbly border-radius on all elements
• Gradient buttons as the primary CTA pattern
• Generic stock-photo-style hero sections
• "Built for X" / "Designed for Y" marketing copy patterns

• Brutalist/Minimal aesthetic + expressive motion → "Heads up: brutalist aesthetics usually pair with minimal motion. Your combo is unusual — which is fine if intentional. Want me to suggest motion that fits, or keep it?"
• Expressive color + restrained decoration → "Bold palette with minimal decoration can work, but the colors will carry a lot of weight. Want me to suggest decoration that supports the palette?"
• Creative-editorial layout + data-heavy product → "Editorial layouts are gorgeous but can fight data density. Want me to show how a hybrid approach keeps both?"
• Always accept the user's final choice. Never refuse to proceed.

• Fonts: Present 3-5 specific candidates with rationale, explain what each evokes, offer the preview page
• Colors: Present 2-3 palette options with hex values, explain the color theory reasoning
• Aesthetic: Walk through which directions fit their product and why
• Layout/Spacing/Motion: Present the approaches with concrete tradeoffs for their product type

1. Loads proposed fonts from Google Fonts (or Bunny Fonts) via

   <link>

   tags
2. Uses the proposed color palette throughout — dogfood the design system
3. Shows the product name (not "Lorem Ipsum") as the hero heading
4. Font specimen section:
   • Each font candidate shown in its proposed role (hero heading, body paragraph, button label, data table row)
   • Side-by-side comparison if multiple candidates for one role
   • Real content that matches the product (e.g., civic tech → government data examples)
5. Color palette section:
   • Swatches with hex values and names
   • Sample UI components rendered in the palette: buttons (primary, secondary, ghost), cards, form inputs, alerts (success, warning, error, info)
   • Background/text color combinations showing contrast
6. Realistic product mockups — this is what makes the preview page powerful. Based on the project type from Phase 1, render 2-3 realistic page layouts using the full design system:
   • Dashboard / web app: sample data table with metrics, sidebar nav, header with user avatar, stat cards
   • Marketing site: hero section with real copy, feature highlights, testimonial block, CTA
   • Settings / admin: form with labeled inputs, toggle switches, dropdowns, save button
   • Auth / onboarding: login form with social buttons, branding, input validation states
   • Use the product name, realistic content for the domain, and the proposed spacing/layout/border-radius. The user should see their product (roughly) before writing any code.
7. Light/dark mode toggle using CSS custom properties and a JS toggle button
8. Clean, professional layout — the preview page IS a taste signal for the skill
9. Responsive — looks good on any screen width

1. Propose, don't present menus. You are a consultant, not a form. Make opinionated recommendations based on the product context, then let the user adjust.
2. Every recommendation needs a rationale. Never say "I recommend X" without "because Y."
3. Coherence over individual choices. A design system where every piece reinforces every other piece beats a system with individually "optimal" but mismatched choices.
4. Never recommend blacklisted or overused fonts as primary. If the user specifically requests one, comply but explain the tradeoff.
5. The preview page must be beautiful. It's the first visual output and sets the tone for the whole skill.
6. Conversational tone. This isn't a rigid workflow. If the user wants to talk through a decision, engage as a thoughtful design partner.
7. Accept the user's final choice. Nudge on coherence issues, but never block or refuse to write a DESIGN.md because you disagree with a choice.
8. No AI slop in your own output. Your recommendations, your preview page, your DESIGN.md — all should demonstrate the taste you're asking the user to adopt.
