tinyworld-tool-icons-and-modesA skill your agent uses when changing Tiny World Builder's mode indicator, boot tool selection, or Esc-to-Select behaviour.
Tinyworld Tool Icons And Modes is an agent skill from jasonkneen/tiny-world-builder. Use when changing Tiny World Builder's mode indicator, boot tool selection, or Esc-to-Select behaviour.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design. The licence is AGPL-3.0.
Read from SKILL.md and the folder at commit 49e8abd. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
npmFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Tinyworld Tool Icons And Modes loads about 1.5k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 741 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.
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.

.claude/skills/tinyworld-tool-icons-and-modes/SKILL.md (or your agent's skills folder).bootApp calls
selectTool(DEFAULT_TOOL) after loadState(), so a restored world's saved
toolId never leaves a fresh session "armed" for building.#build-play-mode toggles
body.tw-play-mode, persists tinyworld:build-play-mode.v1, and exposes
window.__tinyworldIsPlayMode() / window.__tinyworldMode. In PLAY mode,
build panels and edit radials are hidden, selection/sub-edit state is cleared,
and mutation paths should be gated through the same edit checks that call
mpEditAllowed().#welcome-modal: the rounded .launch-modal shows
assets/twlogo.png with Tinyverse, Battleworlds, Build, and Play buttons,
includes the compact "Created by Jason Kneen" footer with @jasonkneen and
@tinyworldsapp links, and hides app chrome via body.welcome-launch-open.
Build/Play call window.__tinyworldMode; Tinyverse waits for
window.__tinyworldWorlds.open() (or the tinyworld:worlds-ready signal)
and opens the Worlds frontend rather than silently falling back to Build.
Battleworlds calls window.__tinyworldBattleworlds.open() when present and
otherwise falls back to Play. Do not bring back the old farm/vehicle welcome
picker for this path, and keep publish.sh copying the assets/ directory
into dist/assets/.#showcase-exit X
button visible. Do not turn it back into a wide "Exit Showcase Esc" text pill;
keep aria-keyshortcuts="Escape" and the existing Escape handler that calls
setShowcaseActive(false).#mode-indicator (HUD chip, updated in updateModeIndicator in
19-tools-toolbar.js) names the current mode and colours itself: calm
mode-select, amber mode-build, red mode-erase. Keep it
pointer-events:none.Esc disarms any build/paint/erase tool back to Select (handler in
20-input-place-erase.js, skipped in first-person walk mode).tp), and first-person walk (fp). Both walk modes are
driven by the same fp controller in 20-input-place-erase.js; tp shows a
chase camera behind the voxel avatar, while fp uses the avatar rig's
getEyeWorldPosition() and hides the head via setFirstPerson(true).
Keep tp in camera-mode schema/import allowlists when touching saved camera
validation.fp avatar is added to the
shared worldGroup, so it must never coexist with a Tinyverse room's own
networked avatar or the player sees two copies of themselves. setCameraMode
redirects fp/tp to perspective while window.__tinyworldInWorldRoom is
set, and 47-worlds-room.js enterRoom calls window.__tinyworldExitWalkMode
(exposed from 20-input-place-erase.js) to dispose any active walk avatar
before spawning the room avatar. The room's own first-person is the surface
roam zoom-in (v key, _sr* in 47), not the builder fp controller.npm test (tools/check.js / smoke-static.js) reconstructs the split app
from tiny-world-builder.html plus engine/**/*.js. Update those static guards
when changing boot mode, launcher chrome, or mode persistence.
.toolbar is the default. The "Show groups" checkbox in
Settings → App (#toolbar-show-groups, persisted as tinyworld:showGroups,
default on) switches modes. When off, body.hide-groups hides only the
bottom toolbar's block tools/group buttons and a floating, resizable,
draggable #tool-palette shows every placeable block (select + all
TOOL_GROUPS tools with house variants expanded + erase). The bottom
toolbar itself must stay visible for utility controls such as Build/Play,
Home, Shield, View modes, Time/weather, Sound, Layers, Settings, and Account.engine/world/35-tool-palette.js.
Blocks are built with buildToolButton(t, { flyout: true }), so they keep
their colors and are highlighted by the same updateToolActiveStates() loop.showGroupsEnabled() returns true on
<=700px regardless of the stored pref (isSmallScreenForGroups()), the
checkbox is disabled there, and a resize listener re-applies across the
breakpoint. The floating palette is unusable on phones, so never let it open
there. The phone toolbar is also compacted to icon-only (labels/chevrons
hidden, smaller buttons) in the @media (max-width: 700px) block.
The grid uses fixed 64px square cells (repeat(auto-fill, 64px)), so resizing
the panel reflows blocks to the nearest square. buildToolbar() calls
rebuildToolPaletteIfActive() so toolbar rebuilds refresh an open palette..flyout.tool-menu) lays its icons out as a
2-row grid block (gridTemplateColumns: repeat(ceil(n/2), auto) set in
renderToolGroupFlyout)..controls rail is no longer visible. Keep its element IDs
in the DOM as stable wiring targets, but put everyday chrome in the bottom
toolbar: Build/Play, Home, Shield, View modes, Time/weather, Settings, and
Account. Import/export must remain owner-gated and should not be added to the
normal user toolbar.#mode-indicator HUD chip has been removed from the DOM;
updateModeIndicator() still runs but no-ops on the missing element.leave icon. The in-world exit that returns to the
world picker uses tw-hud-back-worlds, the reply glyph, and
worlds.backToWorlds so it is not confused with logging out.© jasonkneen, AGPL-3.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
