apple-dev-skills CLAUDE.md

apple-dev-skills CLAUDE.md is an instructions file for coding agents from markdavidgan/apple-dev-skills. It costs 2,292 tokens per session, scanned A, a copy of apple-dev-skills AGENTS.md, MIT.

Repository instructions for maintaining a collection of Apple development skills across coding-agent platforms. Source files are validated and then used to generate platform-specific bundles.

In plain words
What is it for?
Use it when changing Apple development skills, agents, commands, MCP configuration, validation, builds, or local installation.
Why use it?
It prevents edits from being made to generated files and keeps source, generated outputs, metadata, and platform rules aligned.

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

apple-dev-skills CLAUDE.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 5d 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.

Origin

This is a copy

94% identical to apple-dev-skills AGENTS.md — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Apple Dev Skills — Agent Guide

This is the standalone Apple development skill repository. It is not part of aether-agent-plugins.


Quick Reference

Task Command
Validate source node scripts/validate.js
Build platforms node scripts/build.js
Install locally ./install.sh --platform claude --local
Install globally ./install.sh --platform claude

Repository Rules

  1. Edit source, not generated platform bundles — skill/agent/command changes begin in src/. Never hand-edit platforms/, .claude-plugin/, or .cursor-plugin/; they are generated by scripts/build.js.
  2. Run validation before committingnode scripts/validate.js must pass.
  3. Regenerate after source edits — After changing any src/ file, run node scripts/build.js and commit source + generated outputs together.
  4. Keep skills self-contained — Cross-reference other skills by name, not by installation-specific file path.
  5. YAML frontmatter is required — Every SKILL.md, agent, and command must have valid frontmatter.
  6. Stay machine-agnostic — Never commit absolute clone paths or credentials. src/mcp/*/mcp.json must keep placeholders/env-var references; real paths/keys belong in machine-local client config.
  7. Product repositories own their overlays. Generic methodology belongs here; consumer repos commit only their product/repository-specific binding layer.

Project-local consumer convention

For a product repository that commits its own Agent Skills, use one provider-neutral source:

AGENTS.md                       # canonical always-on operating contract
CLAUDE.md -> AGENTS.md          # compatibility alias when symlinks are supported
GEMINI.md -> AGENTS.md          # compatibility alias when symlinks are supported
.agents/skills/                 # canonical committed repo-owned Agent Skills
.claude/skills/<name>           # compatibility symlink or tiny Claude-only adapter
apple-overlays.json             # optional root descriptor for generated Apple overlays

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.
