What it does

Kototoro Glass Panel Artifacts is an agent skill from Kototoro-app/Kototoro. Diagnose and fix Kototoro Compose Material3 sheet, dialog and popup glass-panel artifacts — an extra light or gray rectangle, a pale plate, rectangular bounds around rounded glass panels, or a background that appears to grow while dragging the display options sheet — by finding which stacked layer draws it.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

The repository describes itself as: Manga, Novel, and Video reader for Android. The licence is Apache-2.0.

Example prompts

  • “/kototoro-glass-panel-artifacts”

Workflow steps

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

  1. Locate the exact composable — usually DisplayOptionsSheet, a top-bar menu, the search sheet, or a details popup — then find its…
  2. Inspect every enclosing Material container. This is the sheet pattern the codebase settled on
  3. Keep the rounded panel in one place — the inner glass surface, never both the Material sheet and the glass content.

What it can do on your machine

Read from SKILL.md and the folder at commit 74bd979. 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

Kototoro Glass Panel Artifacts loads about 1.2k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 533 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Diagnose and fix Kototoro Compose Material3 sheet, dialog and popup glass-panel artifacts — an extra light or gray rectangle, a pale plate, rectangular bounds around rounded glass panels, or a background that appears to grow while dragging the display options sheet — by finding which stacked layer draws it.

Kototoro Glass Panel Artifacts

For glass panels inside a Material sheet, dialog or popup. Chrome — top-bar pills, the search button, bottom nav — has its own notes in kototoro-artwork-chrome-artifacts, and the liquid path belongs to backdrop.

Core Lesson

Do not assume the glass layer is broken. These artifacts come from stacked drawing layers:

  • Material3 ModalBottomSheet, Dialog, DropdownMenu, Surface or Card default container and elevation.
  • Two layers tinting one area: the glass container colour plus a same-shape Material Surface colour.
  • Shape mismatch: a rectangular elevation or tint layer behind rounded content.
  • A Surface shadow reading through a translucent fill. kototoro-artwork-chrome-artifacts owns the general form of that rule.
  • GlassSurface(dialogSurface = true) still carrying prominentStyle() elevation. In the display options issue that was the last remaining rectangle, and zeroing the dialog surface elevation removed it.

First Checks

  1. Locate the exact composable — usually DisplayOptionsSheet, a top-bar menu, the search sheet, or a details popup — then find its GlassSurface caller. Feature-owned ModalBottomSheet content goes through KototoroSheetSurface.
  2. Inspect every enclosing Material container. This is the sheet pattern the codebase settled on:
kotlin
ModalBottomSheet(
    onDismissRequest = onDismissRequest,
    sheetState = sheetState,
    dragHandle = null,
    shape = RoundedCornerShape(0.dp),
    containerColor = Color.Transparent,
    tonalElevation = 0.dp,
) {
    KototoroSheetSurface(
        modifier = Modifier.padding(horizontal = 12.dp, vertical = 8.dp),
    ) { /* content */ }
}
  1. Keep the rounded panel in one place — the inner glass surface, never both the Material sheet and the glass content.

GlassSurface Rules

dialogSurface = true, which is what KototoroSheetSurface passes, must differ from inline cards and bars in core/ui/glass/GlassSurface.kt:

  • It skips the liquid path outright (isIosStyle && glassEnabled && backdrop != null && !dialogSurface).
  • It forces tonalElevation = 0.dp, draws no hairline border, and resolves shadowElevation to 0.dp through resolveFallbackShadowElevation(..., flat = true).
  • Over artwork it forces an opaque surfaceContainer fill; the iOS path without a backdrop uses 0.98 alpha.
  • prominentStyle() elevation must not reach a sheet or dialog without that override.

Diagnosing ambiguous cases

Log bounds on both the Material content slot and the inner glass surface, then compare them. DisplayOptionsSheet.kt keeps a BuildConfig.DEBUG-gated DebugBoundsBox that only logs changed values; copy that shape instead of adding ad-hoc logging.

  • Outer slot grows while the inner glass does not ⇒ suspect the Material sheet/dialog container or the window background.
  • Inner glass bounds match the artifact ⇒ suspect the glass container colour, its tint, shape clipping, or Surface elevation.
  • Coordinates change while sizes stay fixed ⇒ the artifact is a fixed layer being moved; drag motion is not the cause.
  • The artifact grows while dragging and the inner glass is already tall ⇒ check whether the panel content itself is taller than expected.

From the fixed display options issue:

text
modal_content_slot size=1272x1370
display_options_glass surface size=1188x1314

Both sizes held steady while dragging, so the rectangle belonged to the inner glass surface, and zeroing dialog Surface elevation fixed it.

Fix Order

Apply in this order so the real cause is not masked:

  1. Make the outer Material containers transparent and zero their elevation.
  2. Give the rounded shape to exactly one layer.
  3. Match the glass clipping and edge treatment to that same shape.
  4. Drop the glass tint where a same-shape Surface colour already supplies the container.
  5. Zero Surface elevation for dialog surfaces.
  6. Only then disable the runtime glass path as a diagnostic, and restore it before finishing.

Cleanup

  • Remove the logging you added unless the user wants it kept. Reusable improvements such as dialogSurface and resolveFallbackShadowElevation stay, because they prevent recurrence.
  • Confirm with ./gradlew :app:compileDebugKotlin --no-daemon, and pin extracted policy with a unit test.
