Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00037 | $0.00546 |
| Opus 5 | $0.00018 | $0.00273 |
| Sonnet 5 | $0.00007 | $0.00109 |
| Haiku 4.5 | $0.00004 | $0.00055 |
Grade A, and why
apple-dev-research 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apple Developer Research
Bundled commands use $PLUGIN_ROOT ($env:PLUGIN_ROOT in PowerShell; same path suffix) for the plugin root. Set it once: use the host's plugin-root variable when defined (Claude Code: PLUGIN_ROOT="$CLAUDE_PLUGIN_ROOT"), otherwise the absolute path of this plugin's root directory.
Use Apple Dev Search for Apple-platform community content when the user wants articles, tutorials, or reading material rather than official docs or generic web results. Do not hard-code service counts; query --counts when counts matter.
Workflow
- Start with one focused query using the user's wording.
- Hard cap ordinary requests at 3 commands total: initial search plus 2 retries. Stop once 3 useful candidates are found.
- If broad/noisy, retry with
--title-onlyand tighter terms. - Use syntax when helpful: quotes,
|,-,*,~1, parentheses. - For fresh reading lists, inspect
--recent. - Verify selected article URLs with Crawl4AI only when snippets are insufficient or candidates are close. Avoid generic web search/Tavily/Firecrawl unless Crawl4AI fails.
- Return 3-8 links with title, blog, date, URL, and one-line relevance.
Commands
python3 "$PLUGIN_ROOT/skills/apple-dev-research/scripts/appledevsearch.py" --query 'build speed' --limit 5
python3 "$PLUGIN_ROOT/skills/apple-dev-research/scripts/appledevsearch.py" --query '"incremental builds" | "compile time"' --title-only --limit 5
python3 "$PLUGIN_ROOT/skills/apple-dev-research/scripts/appledevsearch.py" --query 'swift testing -uikit' --limit 5
python3 "$PLUGIN_ROOT/skills/apple-dev-research/scripts/appledevsearch.py" --recent --limit 8
python3 "$PLUGIN_ROOT/skills/apple-dev-research/scripts/appledevsearch.py" --counts
Use full text for errors/API/framework names; title-only for broad topics. Keep user terminology in at least one query before expanding synonyms.
Reusable search URL:

What ships with it
2 files 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-research is a skill published in the GitHub repository Xopoko/build-swift-apps (45 stars, last pushed 11d ago), licensed MIT. It adds 37 tokens to every session and 546 once invoked, about $0.0002 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.
