What it does

Gridgeist is an agent skill from ohmiler/gridgeist. Use when creating, redesigning, or reviewing web interfaces that need product-specific structure, clear hierarchy, responsive composition, accessible interaction, or relief from generic AI-generated SaaS aesthetics. Adapt grid, typography, imagery, motion, and product evidence to the established brand—including technical, editorial, image-led, warm, playful, and utilitarian directions—across React, Next.js, Tailwind CSS, HTML/CSS, landing pages, dashboards, documentation, portfolios, and interactive tools.

Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files and assets (for example `agents/openai.yaml`, `references/design-language.md` and `references/review-checklist.md`).

It sits in Frontend & Design, covering Frontend development, Landing pages and Typography. It works with Next.js, React and Tailwind CSS. The repository describes itself as: Gridgeist turns product intent into a rigorous visual system—without the generic AI SaaS aftertaste. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 1c4aa94. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gridgeist loads about 2.6k tokens when it runs, and up to ~7.2k if it reads all its reference files. Until then it costs about 130 tokens; SKILL.md has 1,242 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~130
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when creating, redesigning, or reviewing web interfaces that need product-specific structure, clear hierarchy, responsive composition, accessible interaction, or relief from generic AI-generated SaaS aesthetics.

Gridgeist

Overview

Craft distinctive, product-native interfaces from audience, content, behavior, and brand intent. Use grid as structural logic; make it visible only when it serves the product.

Select a mode

Intent and authorizationModeStart with
Build an interface without an existing designCreateAudience, primary task, content, and evidence
Change an existing interface with permission to editRedesignPreserved behavior, brand signals, and state inventory
Diagnose without changing filesReviewPrioritized findings grounded in rendered evidence

Let user authorization determine whether files change. Permission to redesign does not authorize choosing among materially different visual theses. Derive direction from explicit user intent or established brand evidence; audience, task, product category, and content may inform hierarchy but do not alone confirm a visual thesis. Use the alignment gate below whenever thesis-level ambiguity remains.

Workflow

  1. Inspect — Understand the audience, primary tasks, brand signals, content, product evidence, routes, components, tokens, and rendered desktop/mobile UI. Inspect existing design-system sources, including DESIGN.md when present, and reconcile them with the implementation and rendered evidence rather than assuming they agree. Inventory important interaction states and constraints. Do not invent customers, metrics, outcomes, research, or compliance.
    • Align direction before editing — Classify the direction as user-confirmed, brand-derived, or provisional. Treat a coherent user direction as confirmed even when it leaves implementation choices open; variations within the same thesis are not material ambiguity. Classify a direction as brand-derived only when existing visual implementation, assets, documented rules, or repeated brand conventions converge on one thesis; product subject matter or copy alone is not enough. When a broad Create or Redesign still supports materially different theses that would change core brand expression, hierarchy, imagery, color, or motion, offer two or three evidence-grounded directions with trade-offs and a recommendation, then ask the user to choose or authorize the recommendation. While the direction is provisional, do not define the replacement system or edit implementation files. Proceed without redundant questions when intent or coherent brand evidence is clear. Do not block Review or narrow repairs; label an unconfirmed Review replacement direction provisional.
    • Hard stop for provisional broad work — A provisional direction is not an implementable direction. End the turn after the options, trade-offs, recommendation, and alignment question. Do not set a thesis, read the system contract, create tokens, edit files, start implementation, or verify a redesign until the user selects a direction or explicitly authorizes the recommendation.
  2. Set a thesis — Write one governing sentence combining audience, primary task, structural logic, brand expression, and a product-native motif. Read design-language.md before choosing the direction, especially for image-led, warm, playful, or otherwise nontechnical brands.
  3. Define the system — Read system-contract.md before making new or changed system decisions. Establish the relevant color, typography, layout, spacing, shape, surface, component, state, media, motion, and responsive rules as one compact contract. Decide whether the grid should be visible, quiet, or invisible. Reuse semantic tokens and existing primitives; keep narrow repairs proportional and do not create a persistent design artifact unless authorized.
  4. Compose — Build hierarchy before detail. Make one area dominant, align related content, vary sections within shared logic, and let the most authentic material—product UI, data, prose, imagery, artwork, code, or the primary tool—carry visual weight.
  5. Implement — Preserve required behavior and states. Follow repository conventions, semantic HTML, keyboard and touch behavior, and existing primitives. Recompose mobile layouts rather than shrinking desktop. Avoid dependencies for simple CSS effects.
  6. Verify — Use review-checklist.md. Render representative widths and exercise primary flows, states, focus behavior, reduced motion, overflow, and dynamic content. Fix clarity and hierarchy before polish. Report what was observed separately from what remains inferred or untested.

For interactive products, inventory at least default, loading, empty, error, success, disabled, and destructive states when applicable. Preserve privacy, safety, data, and platform constraints as product behavior, not optional polish.

Coordinate companions

  • Keep Gridgeist as the sole owner of product and visual direction. Do not automatically combine it with another broad frontend-design or art-direction skill. If the user explicitly requests both, establish one direction owner before editing instead of silently blending their defaults.
  • Explicit overlap gate — When the user requests Gridgeist plus another broad visual-design skill, state the overlap and recommend one direction owner before selecting a thesis or editing; use Gridgeist by default for product-native, brand-adaptive work. Do not silently ignore the requested companion or run both visual theses. After ownership is clear, use only non-conflicting implementation or verification help from the other skill unless the user chooses it as owner.
  • Use context capabilities during Inspect, asset generation after the thesis, technical audits after implementation, and browser automation during Verify.
  • Treat companions as optional. Do not block work or add dependencies when they are unavailable.

Anti-slop contract

  • Use one thesis and one coherent system.
  • Preserve or deliberately evolve the brand instead of importing a house aesthetic.
  • Build hierarchy through scale, position, density, rhythm, and contrast.
  • Give grid visibility, borders, radii, shadows, gradients, and motion defined roles.
  • Prefer authentic product evidence; label sample or fictional material and never fabricate proof.
  • Give sections or workflows distinct compositions within shared structural logic.

Repeated rounded cards, centered hero copy, gradient blobs, excessive pills, uniform sections, arbitrary icon boxes, generic claims, and technical chrome on nontechnical brands are diagnostic signals, not automatic violations. Replace weak structure with a stronger product-specific idea.

Decision reference

DimensionDecide from
StructureInformation order, task flow, shared alignments, and the brand's degree of regularity
TypeBrand voice, reading needs, and role hierarchy; reserve mono for genuinely technical content
Visual leadProduct UI, data, prose, imagery, artwork, code, or a primary interactive surface
Shape and surfaceBrand geometry, containment, adjacency, state, and interaction—not fashion
ColorExisting brand palette and semantic roles; do not assume neutral plus one accent
ComponentsProduct tasks, shared anatomy, variants, density, state behavior, and repository conventions
MotionCausality, feedback, spatial change, and tone, with reduced-motion support
ResponsivePriority, order, density, input method, and content behavior at each range

Output contract

For user-confirmed or brand-derived Create or Redesign, provide Direction with the thesis and preserved constraints, complete responsive Implementation, and Verification evidence naming observed viewports, flows, states, and remaining gaps. When system decisions materially change, identify the relevant contract or where its tokens and component rules are implemented. For provisional broad Create or Redesign, output only the alignment options, trade-offs, recommendation, and question; do not include Implementation or redesign Verification claims. For Review, make no edits and provide a one-line Verdict, prioritized findings with location, evidence, impact, and the smallest coherent correction, plus one replacement Direction. Never claim verification without observation.

Common mistakes

MistakeCorrection
Treating Gridgeist as a visible-grid presetUse grid as underlying logic and expose it only when the brand benefits
Copying a reference literallyExtract principles and preserve the user's identity and content
Styling before understanding behaviorInventory tasks, constraints, and states before composing
Making minimalism emptyAdd useful evidence and controlled density
Styling components one at a timeDefine shared anatomy, tokens, variants, and states before polishing instances
Improving the default state onlyDesign loading, empty, error, success, disabled, and destructive paths
Stacking desktop UI on mobileRedesign order, density, navigation, media, and interaction
Reporting subjective taste aloneTie findings to comprehension, usability, consistency, brand, or accessibility
Reporting automated checks as user evidenceSeparate technical verification from usability, safety, and research claims

Contrasting examples

Redesign dense API documentation with a visible information grid, precise code states, and verified mobile navigation.

Redesign a warm image-led portfolio with an invisible alignment system, expressive type, artwork-led pacing, and accessible project narratives.
