Instructions file for CodexOpenCode

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

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

iOS-Design-Agent-Skill 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 7d 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

Agent Guidelines

This repository contains the iOS Design Agent Skill — a design-critique skill for iOS/SwiftUI apps.

In Scope

  • iOS/SwiftUI UI design review and critique
  • Typography, color systems, spatial composition, motion, and atmospheric depth
  • SwiftUI modifier suggestions and code examples
  • Accessibility (Dynamic Type, dark mode, VoiceOver, reduced motion)
  • Apple Human Interface Guidelines alignment

Out of Scope

  • General Swift language guidance (use a Swift skill instead)
  • Architecture patterns (MVVM, VIPER, TCA, etc.)
  • Backend, networking, or data layer code
  • Non-Apple platforms
  • Build system, CI/CD, or tooling configuration
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.
