ValkurAssetPostprocessor.cs — auto-applies import rules on every reimport.CharacterAtlasBuilder.cs / TileAtlasBuilder.cs / SpriteAtlasBuilder.cs — build atlases.TilePaletteBuilder.cs — generate Unity TilePalette from imported tiles.BulkReimportTool.cs — force-reimport a folder applying current postprocessor rules.tools/atlas/ (Python) — standalone audit/normalize utilities (Pillow + stdlib).Assets/_Project/Art/<category>/ folder. The postprocessor applies the right PPU/pivot/filter automatically.mcp_unity_manage_asset(action="search", page_size=25, generate_preview=false).Valkur > Atlas > Build *).Valkur > Audio > Music Scanner (music) or just drop SFX into Audio/SFX/ (postprocessor handles import).Performance diagnosis + optimization for Valkur — Profiler/Recorder API workflow, three-axis bottleneck model (CPU main / CPU render / GPU), URP HDR/shadow/post-process tuning, UGUI canvas pipeline, GC reduction patterns (hoisted buffers, no per-frame allocations), tick-rate throttling, and the catalog of optimizations already applied. Load whenever chasing low FPS, frame-time spikes, GC pauses, or memory pressure.
Performance diagnosis and optimization for the Valkur Unity project. Use when chasing low FPS, frame-time spikes, GC pauses, expensive Updates, GPU bottlenecks, render-thread stalls, or memory pressure. Covers Profiler/Recorder API workflow, hot-path patterns, URP/UGUI specifics, GC reduction, and Valkur's catalog of previously-applied optimizations.
Manage the Valkur Unity asset import pipeline — sprite import policies, atlas building, PPU configuration, pivot normalization, audio import. Covers ValkurAssetPostprocessor, CharacterAtlasBuilder, TileAtlasBuilder, TilePaletteBuilder.
One-stop quick reference for Valkur conventions — assemblies, layers, sorting, code style, the cardinal "console must be clean" rule, key gotchas. Load this skill at the start of any non-trivial task to keep the rules close to hand.
General Unity development for the Valkur project. Use when writing or refactoring Unity C# scripts, designing systems, working with MCP for Unity tools, debugging runtime issues, configuring assemblies/layers/ScriptableObjects, or troubleshooting domain-reload, Cinemachine, URP 2D, Tilemap, UI Toolkit/uGUI, or input issues. Covers MCP workflow, console verification, performance patterns, hot-reload safety, and project conventions.
Markdown documentation conventions for Valkur — markdownlint config, MD028 (no blank lines inside blockquotes), MD029 disabled globally for ordered lists, frontmatter style, table layout. Load when creating or editing any `.md` file (roadmaps, audits, checklists, migration guides) so lint warnings stay at zero.
