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.
Manage Unity tests for the Valkur project. Use when: creating new test files, fixing failing tests, reorganizing test folders, enforcing namespace conventions, diagnosing EditMode NRE/TMP issues, running the test suite via MCP, auditing test coverage, or deciding which folder/namespace a new test belongs to. Covers EditMode and PlayMode, NUnit patterns, MCP test workflow, folder→namespace mapping, and all known EditMode gotchas.
