Swift-Agent-Skill AGENTS.md

Swift-Agent-Skill AGENTS.md is an instructions file for Codex, OpenCode from rouzbeh-abadi/Swift-Agent-Skill. It costs 732 tokens per session, scanned A, original, MIT.

Guidance for AI agents working on Swift software, including the Swift language, Apple development, concurrency, packages, tests, linting, and formatting. It emphasizes common, maintainable Swift practices and separates established facts from personal preferences.

In plain words
What is it for?
Use it when reviewing or writing Swift code, designing APIs, handling optionals and errors, using concurrency, configuring Swift Package Manager, writing tests, or applying SwiftLint and formatting.
Why use it?
It helps an agent make broadly applicable Swift decisions without narrowing the advice to one framework, architecture, or team convention.

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

Swift-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 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.

Agent Guidelines for Swift Expert Skill

This document guides AI agents working with this repository so the published skill stays broad, practical, and trustworthy for real Swift development work.

Core Principles

1. Broad Swift Scope

This is a general Swift skill, not a single-topic skill. Cover:

  • core Swift language patterns
  • optionals, errors, and API design
  • Swift concurrency
  • Swift Package Manager workflows
  • testing guidance
  • SwiftLint and formatting support

Do not narrow the skill to only:

  • SwiftLint
  • SwiftUI
  • one architecture style
  • one team-specific coding convention

2. Prefer Standard Swift Guidance

Use common Swift and Apple ecosystem practices. Prioritize:

  • language clarity
  • safe and idiomatic APIs
  • maintainable concurrency patterns
  • readable package and test setup
  • widely used lint and formatting conventions

Avoid inventing custom rules unless the user explicitly wants opinionated team standards.

3. Facts First, Opinions Second

Lead with correctness and maintainability. Use strong language for:

  • unsafe patterns like ! or as!
  • concurrency misuse
  • weak error handling
  • obviously brittle package configuration

Use softer language for:

  • naming nuance
  • file organization
  • access control preferences
  • style choices where teams reasonably differ

4. Safe Edits First

Prefer low-risk improvements before deeper refactors. Good candidates:

  • mechanical formatting cleanup
  • redundant syntax removal
  • isEmpty and boolean simplifications
  • safer optional handling
  • small package manifest cleanups
  • focused test additions around touched behavior

Use more care with:

  • public API changes
  • cross-module renames
  • concurrency model changes
  • sweeping architecture rewrites

Content Guidelines

Include These Topics

  • common Swift language pitfalls and modern idioms
  • protocol and type design guidance
  • error handling and optional handling
  • structured concurrency patterns
  • package manifests and dependency usage
  • unit testing and test readability
  • SwiftLint-backed formatting and linting guidance

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.
