Arcane v0.16.1

[0.16.1] - 2026-02-24

Added

• arcane check command — fast type-checking without running tests; catches silent hot-reload failures
• /check skill — scaffolded projects include skill for proactive type checking
• PostToolUse hook — auto-runs type check after file edits in scaffolded projects

Changed

• Scaffold files now self-contained — no cross-file import dependencies that break when agents modify code
  • game.ts: minimal GameState with just rng, no external imports
  • visual.ts: inlined ZOOM/BG_COLOR, commented camera follow
  • config.ts: all exports commented (template examples only)
  • game.test.ts: minimal test without signature assumptions
• AGENTS.md visual guidance — enriched Quick Start with starfield, layered glows, particle trails; added Visual Depth Techniques and Visual Composition sections with shape variety examples
• Tips section deduplicated — removed advice that overlapped with Common Mistakes

Fixed

• AGENTS.md accuracy errors — setBackgroundColor example no longer divides by 255 (rgb() already returns 0-1 floats); rgb() call moved outside onFrame to avoid GC
• Iteration cycle numbering — was 1,2,4,5; now correctly 1,2,3,4,5
