ui-ux-guide: Instructions file for Codex

AGENTS.md

ui-ux-guide AGENTS.md is an instructions file for Codex, OpenCode from oil-oil/ui-ux-guide. It costs 868 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for maintaining a user-experience and interface design guide. They define shared usability rules separately from visual style choices, such as typography, colors, spacing, and motion.

In plain words
What is it for?
Use them when editing the related design guide, its documentation, examples, or style-family library, while keeping advice practical and style-neutral.
Why use it?
They prevent general usability principles from being confused with preferences for one visual style. This keeps the guide useful for different products and audiences.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is oil-oil/ui-ux-guide's own configuration. It tells Codex and OpenCode how to work on ui-ux-guide itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ui-ux-guide configures →

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

ui-ux-guide 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 8d 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.

oiloil-ui-ux-guide Agent Instructions

This repository uses AGENTS.md as the shared instruction entry for multi-agent tools.

Scope

  • Applies to the whole repository.
  • Used when maintaining skills/oiloil-ui-ux-guide/SKILL.md, README.md, index.html, reference files, and the style-family library.

Repository goals

  • Keep this Skill style-neutral. It is not a "modern minimal" advocacy tool — it's a consultation tool that supports multiple style families.
  • Keep outputs implementable, not generic slogans.
  • Keep design guidance applicable across products of very different audiences (B2B SaaS, education, hospitality, indie tools, etc.).

Two-layer rule architecture (do not collapse this)

The skill maintains a strict separation:

  • UX Hard Rules — perceptual / cognitive / task-level facts that hold across all visual styles. Examples: task-first hierarchy, state coverage, affordance, error prevention. These are global.
  • Style Lens — a chosen "style family" supplies font / color / spacing / radius / shadow / motion defaults for that family only. Each family has its own anti-patterns.

When editing the skill, never move a Style Lens preference into the Hard Rules layer, and never let one family's anti-patterns appear as a global rule. Specific things that belong in style families and not in hard rules:

  • Font allow/deny lists (Inter vs Plus Jakarta vs Spectral)
  • Pure black / pure white usage
  • OKLCH vs HSL preference
  • Specific radius ceilings or floors
  • Bounce / no-bounce motion
  • Lucide / Phosphor / Heroicons specifically

Behavioral rules for the consultant role

  • Listen before recommending. Open with questions, not opinions. Recommendations only when asked.
  • Neutral options. When presenting choices, no starred recommendation unless the user asks "what do you think?".
  • No loaded labels ("premium" / "efficient" steers the answer; use neutral descriptors and concrete references).
  • One question at a time with a default the user can accept silently.
  • Defer to the user's stated preference, unless it violates a UX Hard Rule. Even then, name the rule and offer one alternative — don't block.
  • Do not impose a style family the user hasn't chosen.

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.
