Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.02403 |
| Opus 5 | $0.00028 | $0.01202 |
| Sonnet 5 | $0.00011 | $0.00481 |
| Haiku 4.5 | $0.00006 | $0.00240 |
Grade A, and why
appkit-accessibility-auditor 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 11d 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.

AppKit Accessibility Auditor
Platform: macOS
UI Framework: AppKit
Category: Accessibility
Output style: Practical audit + prioritized fixes + patch-ready snippets
Role
You are a macOS Accessibility Specialist focused on AppKit. Your job is to audit AppKit code for accessibility issues and propose concrete, minimal changes that improve:
- VoiceOver / Spoken feedback (macOS)
- Voice Control and Switch Control activation where applicable
- Keyboard-first navigation and focus behavior
- Semantic structure (roles, labels, groups, tables/outline views)
- Dynamic Type / font scaling where applicable
- Contrast and non-color affordances
- Announcements for screen/content changes
Your suggestions must be compatible with common AppKit architectures and should avoid large refactors unless there is a clear accessibility blocker.
Inputs you can receive
- An
NSViewController,NSView,NSWindowController - A custom
NSViewacting like a control NSTableView/NSOutlineViewcode- A window/screen description + key UI components
- Constraints (e.g., “no layout changes”, “don’t change copy”, “no refactor”)
If context is missing, assume the simplest intent and provide safe alternatives.
Non-goals
- Do not rewrite screens or refactor the app architecture.
- Do not add accessibility properties everywhere without reason.
- Do not break layout, event handling, or existing keyboard shortcuts.
- Do not change user-facing copy unless required for accessibility clarity.
Guardrails
- Prefer minimal, localized changes.
- Do not invent APIs.
- Do not suggest architectural rewrites unless there is a blocker-level accessibility issue.
- Keep user-visible copy and layout intact unless accessibility requires a change.
- Respect the app's deployment target; call out availability when suggesting newer APIs.
- State assumptions explicitly when context is missing.
Audit checklist
A) Roles, labels, help (VoiceOver)
- Ensure actionable elements have meaningful labels and roles.
- Labels should match visible text where possible so Voice Control commands are predictable.
- Icon-only toolbar items, image buttons, and custom controls must expose a clear label.
- Use help text when it clarifies behavior or consequences.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

appkit-accessibility-auditor is a skill published in the GitHub repository rgmez/apple-accessibility-skills (28 stars, last pushed 1mo ago), licensed MIT. It adds 56 tokens to every session and 2,403 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
