make-interfaces-feel-better: Instructions file for Codex

AGENTS.md

make-interfaces-feel-better AGENTS.md is an instructions file for Codex, OpenCode from jakubkrehel/make-interfaces-feel-better. It costs 397 tokens per session, scanned A, original, MIT.

Repository instructions for a documentation-only agent skill that reviews and improves the visual polish of user interfaces. They explain its files, authoring limits, and how guidance on typography, surfaces, animation, icons, and performance is organised.

In plain words
What is it for?
Use them when editing this interface-review skill, its guidance files, its quick-reference links, or its installation metadata.
Why use it?
They keep edits focused on interface polish instead of turning the skill into a full accessibility, layout, or writing audit. They also explain how the skill’s documentation and metadata must stay consistent.

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

make-interfaces-feel-better 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.

What it actually says

AGENTS.md

This file provides guidance to Codex (Codex.ai/code) when working with code in this repository.

What this repository is

A standalone agent skill for reviewing and improving interface polish, published for installation via npx skills add jakubkrehel/make-interfaces-feel-better. It is documentation-only; there is no build, lint, or test tooling.

Structure

The skill lives in skills/make-interfaces-feel-better/:

  • SKILL.md is the entry point. Its YAML frontmatter contains name and description. The body contains the philosophy, a Quick Reference table, numbered Core Principles, a Common Mistakes table, and a Review Output Format section.
  • typography.md, surfaces.md, animations.md, icons.md, and performance.md contain detailed guidance beyond the entry-point principles. Link to them from the Quick Reference table using relative paths.
  • agents/openai.yaml contains UI metadata and must stay aligned with the skill's scope.

Authoring conventions

  • Keep the skill focused on interface-polish details. Do not expand it into a complete accessibility, layout, color-system, or UX-writing audit.
  • Make principles prescriptive and specific, but scope them when context changes the correct answer. Avoid unconditional rules when reduced motion, interaction frequency, semantics, or an existing design system requires a different approach.
  • Match the target project's existing styling system (Tailwind vs. plain CSS vs. CSS-in-JS) rather than imposing one.
  • Keep detailed recipes and code examples in the reference files; keep only essential selection guidance in SKILL.md.
  • Update the frontmatter description and agents/openai.yaml when the skill's discovery scope changes.
  • Preserve the quick and full review modes, finding caps, evidence requirements, rejected candidates, verification, and verdict.
Changes

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.
