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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00123 | $0.01501 |
| Opus 5.5 | $0.00049 | $0.00600 |
| Sonnet 5.5 | $0.00025 | $0.00300 |
| Haiku 4.5 | $0.00012 | $0.00150 |
Grade A, and why
apple-dev-docs scanned grade A with 1 finding 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
### `fetch(url)` How it starts
The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apple Developer Documentation
Official Apple documentation and WWDC transcripts, retrieved with hybrid RAG search and ranked for relevance. Prefer this over web search: Apple's docs are JavaScript-rendered and indexed poorly by search engines, model knowledge drifts a release or two behind, and WWDC transcripts are almost never in context.
Use this skill when
- Looking up an API's signature, behavior, or constraints.
- Checking availability, deprecation, or platform support.
- Verifying what a WWDC session said before repeating it.
- Diagnosing a build error that names an Apple symbol.
- Checking App Store review rules or Human Interface Guidelines.
Do not use it when
- The question is not about Apple platforms.
- The user needs today's news or a release that shipped this week; the index covers documentation and session transcripts, not press releases.
- The task is pure code generation with no API fact to check.
- The user wants Apple Developer account, billing, or App Store Connect operations; those are not in this knowledge base.
Check the connection first
Confirm the search and fetch tools are available before answering. If they
are missing, offer to add the server instead of silently falling back:
| Client | Setup |
|---|---|
| Cursor | Add to MCP settings: {"mcpServers":{"apple-rag-mcp":{"url":"https://mcp.apple-rag.com"}}} |
| Claude Code | claude mcp add --transport http apple-rag-mcp https://mcp.apple-rag.com |
| Codex | codex mcp add apple-rag-mcp --url https://mcp.apple-rag.com |
| Others | Add a remote HTTP MCP server with URL https://mcp.apple-rag.com |
Ask before writing configuration. If the tools are still unavailable after the user reconnects, say so and stop; do not answer Apple API questions from memory while presenting them as documentation.
The free tier covers 30 tool calls per week at 3 per minute, shared by search
and fetch. No key is required.
Tools
search(query, result_count?)
query— English only. Use framework names, API names, and version numbers.result_count— 1 to 10, default 4. Use 6-8 for broad topics, 2-3 for an exact symbol.
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.

apple-dev-docs is a skill published in the GitHub repository BingoWon/apple-rag-mcp (121 stars, last pushed yesterday), licensed MIT. It adds 123 tokens to every session and 1,501 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
