What it does
Focus Engine is an agent skill from dpearson2699/swift-ios-skills. Implements keyboard, directional, and scene-level focus behavior across SwiftUI and UIKit. Use when managing @FocusState, defaultFocus, focused values, focusable interactions, focus sections, tvOS geometric focus and Siri Remote navigation, watchOS Digital Crown input, visionOS connected-device focus versus gaze hover/input targets, macOS key view loop and Full Keyboard Access, focus restoration after presentation changes, custom focus routing with UIFocusGuide, or debugging focus with UIFocusDebugger.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/focus-debugging.md` and `references/focus-patterns.md`).
It sits in Mobile, covering iOS development. It works with SwiftUI, macOS and iOS. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- Managing @FocusState
- Focusable interactions
- TvOS geometric focus and Siri Remote navigation
- WatchOS Digital Crown input
Example prompts
- “Use the focus-engine skill to implement keyboard, directional, and scene-level focus behavior across SwiftUI and UIKit”
- “/focus-engine”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Mixing accessibility focus and keyboard or directional focus in the same mental model.
- Storing @FocusState in shared models instead of the owning view.
- Setting multiple competing default focus targets on one screen.
- Using .focusable() on decorative views.
- Forgetting focus restoration after sheets, popovers, or custom overlays.
- Reaching for UIFocusGuide before trying focusSection() on macOS or tvOS, or better layout grouping in SwiftUI.
- Using gesture handlers for primary actions on custom focusable controls instead of a semantic Button when possible.
- Treating visionOS gaze hover as focus; reserve focus guidance for connected input such as keyboards and game controllers.
What it can do on your machine
Read from SKILL.md and the folder at commit 8d90fd1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Focus Engine loads about 2.4k tokens when it runs, and up to ~6.2k if it reads all its reference files. Until then it costs about 130 tokens; SKILL.md has 671 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 671 words (~2,443 tokens).
“Focus behavior for SwiftUI and UIKit apps targeting iOS 26+, iPadOS, macOS, tvOS, and visionOS connected-input paths. Covers keyboard focus, directional focus, scene-focused values, focus restoration, and UIKit focus guides. focusSection() guidance in this skill applies to macOS and tvOS…”
