Compose Focus Navigation

What it does

When your agent uses it

• Reviewing Jetpack Compose UI for TV
• Accessibility focus
• D-pad navigation
• FocusProperties

Example prompts

• “/compose-focus-navigation”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Request initial or restored focus from LaunchedEffect, keyed to the condition that makes the target present. For lazy content, keep…
2. 2Keep default spatial search unless a concrete edge, jump, or trap is wrong. Encode only those exceptions with focusProperties.
3. 3Handle keys only for behavior that is not normal click or traversal. Consume exactly the handled event; throttle rapid D-pad work at its…
4. 4Restore by semantic identity after refresh: retain the focused id when it exists, otherwise choose a deterministic fallback.
5. 5Test with one concrete key/D-pad interaction and focused semantics. When the behavior under review is user-triggered, do not substitute…
6. 6Finish when all intentional targets and exceptional edges are encoded, loading/refresh behavior has a stable focus policy, and tests use…

What it can do on your machine

Read from SKILL.md and the folder at commit f872f97. 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 kotlin).

  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

Compose Focus Navigation loads about 994 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~53

When it runs · the whole SKILL.md, loaded when a task matches

~994

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

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.

description

Use when writing or reviewing Jetpack Compose UI for TV, keyboard, desktop, accessibility focus, D-pad navigation, FocusRequester, focusProperties, key events, or initial focus behavior.

val requester = remember { FocusRequester() }

Button(
    onClick = onClick,
    modifier = Modifier
        .focusRequester(requester)
        .onFocusChanged { state -> isFocused = state.isFocused },
) {
    Text("Play")
}

val initialFocus = remember { FocusRequester() }

LaunchedEffect(initialFocus) {
    initialFocus.requestFocus()
}

LaunchedEffect(items.isNotEmpty()) {
    if (items.isNotEmpty()) {
        firstItemRequester.requestFocus()
    }
}

Modifier.focusProperties {
    up = headerRequester
    down = firstRowRequester
    left = FocusRequester.Cancel
}

Modifier.onPreviewKeyEvent { event ->
    if (event.type == KeyEventType.KeyUp && event.key == Key.Back) {
        onBack()
        true
    } else {
        false
    }
}
