Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gridgeist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 authorization Mode Start with
Build an interface without an existing design Create Audience, primary task, content, and evidence
Change an existing interface with permission to edit Redesign Preserved behavior, brand signals, and state inventory
Diagnose without changing files Review Prioritized 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.
