What is it for?
Use it when creating or changing AetherPane frontend pages. It helps guide decisions about page structure, typography, spacing, media, motion, and high-level glass-style surfaces.

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

aetherpane AGENTS.md 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 6d 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.

AetherPane Project Guidance

Scope

  • This project currently focuses only on web UI.
  • Do not add non-web integrations, native app work, CLI packaging, MCP, or A2A in this repo unless explicitly requested.

Project Identity

  • The project name is AetherPane.
  • AetherPane is a web-focused UI system for building premium, polished frontend pages.
  • The style direction combines:
    • Tahoe / Liquid Glass-inspired surface treatment
    • Apple.com-inspired module structure
    • Apple.com-inspired typography rhythm
    • Apple.com-inspired restrained transitions
    • strong readability and maintainable frontend structure

Core Goals

  • Help produce beautiful, premium-looking web interfaces.
  • Build a system that is directly usable for real frontend pages, not just static visual experiments.
  • Focus on structure, rhythm, spacing, hierarchy, media usage, and restrained motion.

Core Principles

  • Fix structure before decoration.
  • Prioritize hierarchy, spacing, readability, and layout rhythm before visual effects.
  • Avoid cheap glassmorphism.
  • Use glass effects only on high-level surfaces such as topbars, sidebars, floating panels, modals, hero foreground panels, and selected premium cards.
  • Keep the overall aesthetic restrained, calm, premium, and highly legible.
  • Prefer one focal point per section.
  • Prefer large visual rhythm, strong spacing, and obvious section hierarchy.
  • Media must support storytelling, not distract from it.
  • Motion must support clarity and premium feel, not showmanship.

Priority Page Types

  • landing / marketing pages
  • product showcase pages
  • dashboard shell / overview pages
  • settings / profile / panel pages

Motion Guidance

  • Use subtle motion only.
  • Prefer fade, slight translate, slight scale, reveal, and gentle hover shifts.
  • Avoid flashy 3D, exaggerated motion, bounce-heavy animations, and noisy scroll gimmicks.

Media Guidance

  • Use large images, short looping demos, screenshots, and small videos only when they improve clarity or premium feel.
  • Do not overload pages with multiple competing media focal points.
  • Keep media containers visually consistent.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
