Agentic eyes for Godot work: cross-platform screenshot CLI (asset/region/window/screen) to budgeted WebP, TEMP editor viewport bridge under .gdskills/, and Taste Receptor Atlas v2 (~237 micro-receptors × 0–2: hierarchy, contrast, typography×41, affordance, space, color, icon, composition, light/FX, motion-tells, anti-slop, originality, identity). Use when agents must see UI, assets, or the editor — not for in-game screenshot Autoloads. Keywords: agent vision, screenshot, WebP, visual QA, taste receptors, typography, UI review, asset sheet, editor viewport, anti-slop.
Consolidated expert library for professional Godot 4.7+ game and application development. Orchestrates 92 Domain Skills through architectural workflows, anti-pattern catalogs, performance budgets, and Server API patterns. Use when: (1) starting a new Godot project, (2) designing game or app architecture, (3) building entity/component systems, (4) debugging performance or physics issues, (5) choosing between 2D/3D approaches, (6) implementing multiplayer, (7) optimizing draw calls or script time, (8) porting between platforms, (9) migrating from 4.6 to 4.7. Primary entry point for ALL Godot development tasks. Keywords: Godot 4.7, AreaLight3D, HDR, Asset Store, godot-master.
Full-history Godot version migration hub. Use when upgrading any Godot project toward the library target (currently 4.7)—from 1.x/2.x legacy eras through 3→4 and hop-by-hop 4.x minors—or finding Domain Skill-scoped migration notes. Trigger keywords: upgrade Godot, migrate Godot version, Godot 3 to 4, Godot 2 to 3, upgrading_to_godot, version migration, breaking changes, convert-3to4, TileMapLayer, AnimationMixer, engine.cfg, project.godot.

A Master implementation treats Time Trials as a State-Validated Sequence. Recording a time is easy; ensuring the player didn't cheat via shortcuts requires a strictly ordered CheckpointManager.
Prevent "Shortcut Cheating" by requiring checkpoints to be cleared in numerical order.
Wire Area body_entered (physics) → TimeTrialManager.pass_checkpoint(index). The manager owns usec timing — see script.
Sample at a fixed rate (e.g. 10 Hz). Lerp position; slerp Quaternion rotation (ghost_recorder.gd / ghost_replayer.gd). Never Euler-lerp ghost heading.
| Format | Best For | Implementation |
|---|---|---|
| Dictionary Array | Prototyping | Simple [{t: 0.1, p: pos}, ...] |
| Typed Array | Performance | PackedVector3Array for positions. |

Central clock. Accumulates Time.get_ticks_usec() (or physics-frame counts). Finish checks must come from physics overlaps.
Captures transform samples with Quaternion "q" fields for slerp-safe playback.
MANDATORY with recorder. Replays samples via position lerp + Quaternion.slerp.
Jitter-buffer for smooth ghost playback during network streaming.
Formatting utility for converting raw time data to human-readable strings.
Store a keyframe only when position/rotation changes beyond a threshold. Persist with FileAccess.open_compressed() + ZSTD; prefer binary floats over JSON.
Store records as int usec/msec. Format with %02d:%02d.%03d for stable UI (e.g. 01:24.450).
LLM-ignorance rule: If a general agent would not know it before reading, load the reference — never delete expert deltas.
Progressive disclosure: open Official Documentation links only when researching a specific API; load Related Skills when routing to a peer domain — do not preload the whole lattice.
