Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00374 | $0.00374 |
| Opus 5.5 | $0.00150 | $0.00150 |
| Sonnet 5.5 | $0.00075 | $0.00075 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
agentic-engineering 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 1mo 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
Apple Developer Toolkit Agentic Engineering Rules
Apply these rules whenever Cursor works in this repository.
Route Tools Explicitly
- Apple docs and WWDC lookup: use
node cli.jsfrom the repo. - App Store Connect work: use
appledev store. - App scaffolding and fix loops: use
appledev build. - Design/platform rules: read only the relevant
references/,skills/ios-rules/, orskills/swiftui-guides/files.
Side Effects Need Approval
Read-only commands are safe by default: docs search, symbols, doc, overview, samples, WWDC lookup, status, validate, diff, docs, doctor, and reference reads.
Ask before any mutation: App Store Connect writes, uploads, TestFlight/App Store publish, pricing, IAP, subscriptions, signing, devices, webhooks, notarization, Xcode Cloud runs, local project writes, simulator launches, hook installation, commits, pushes, PRs, merges, releases, or tags.
Never post to X/Twitter from this repository or skill.
Memory and Observability
- Do not persist raw task logs, App Store state, generated code, build errors, credentials, or temporary decisions to long-term memory.
- Keep run artifacts in repo-local files when needed.
- Summarize what was checked, what changed, what did not change, and remaining risks.
Upstream Sync
After upstream sync commits, run:
bash scripts/apply-agentic-engineering.sh
Then check:
git diff --check -- README.md SKILL.md skills/apple-developer-toolkit/README.md
npx skills add . --list --full-depth
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.

agentic-engineering is a cursor rule published in the GitHub repository Abdullah4AI/apple-developer-toolkit (11 stars, last pushed 3d ago), licensed MIT. It adds 374 tokens to every session, about $0.0015 per session on Opus 5.5. 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 2026-08-31.
