AvdLee/SwiftUI-Agent-Skill is a portable set of expert guidance for AI coding tools that work with SwiftUI, Apple’s framework for building app interfaces. It helps teams and developers review, refactor, and write SwiftUI code involving state, view structure, performance, and newer visual APIs. The catalogue entries provide the skill and plugin instructions that agents use to apply this guidance.

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 | $0.00077 | $0.01079 |
| Opus 5 | $0.00039 | $0.00540 |
| Sonnet 5 | $0.00015 | $0.00216 |
| Haiku 4.5 | $0.00008 | $0.00108 |
Grade A, and why
update-swiftui-apis 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 10d 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.

Update SwiftUI APIs
Systematically scan Apple's developer documentation via the Sosumi MCP, identify deprecated SwiftUI APIs and their modern replacements, and update skills/swiftui-expert-skill/references/latest-apis.md.
Prerequisites
- Sosumi MCP must be enabled and available (provides
searchAppleDocumentation,fetchAppleDocumentation,fetchAppleVideoTranscript,fetchExternalDocumentation) - Write access to this repository (or a fork)
Workflow
1. Understand current coverage
Read skills/swiftui-expert-skill/references/latest-apis.md to understand:
- Which deprecated-to-modern transitions are already documented
- The version segments in use (iOS 15+, 16+, 17+, 18+, 26+)
- The Quick Lookup Table at the bottom
2. Load the scan manifest
Read references/scan-manifest.md (relative to this skill). It contains the categorized list of API areas, documentation paths, search queries, and WWDC video paths to scan.
3. Scan Apple documentation
For each category in the manifest:
- Call
searchAppleDocumentationwith the listed queries to discover relevant pages. - Call
fetchAppleDocumentationwith specific documentation paths to get full API details. - Look for deprecation notices, "Deprecated" labels, and "Use ... instead" guidance.
- Note the iOS version where the modern replacement became available.
- Optionally call
fetchAppleVideoTranscriptfor WWDC sessions that announce API changes.
Batch related searches together for efficiency. Focus on finding new deprecations not yet in latest-apis.md.
4. Compare and identify changes
Compare findings against existing entries. Categorize results:
- New deprecations: APIs not yet documented in
latest-apis.md - Corrections: Existing entries that need updating (wrong version, better replacement available)
- New version segments: If a new iOS version introduces deprecations, add a new section
5. Update latest-apis.md
Follow the established format exactly. Each entry must include:
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.

update-swiftui-apis is a skill published in the GitHub repository AvdLee/SwiftUI-Agent-Skill (3,508 stars, last pushed 28d ago), licensed MIT. It adds 77 tokens to every session and 1,079 once invoked, about $0.0004 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.
