Provides guidelines for directly editing Unity YAML-serialized asset files for Unity projects. Make sure to use this skill whenever creating, editing, or modifying simple YAML asset files (ScriptableObjects, Materials, etc.) via Edit/Write tools without going through the Unity Editor. This includes adjusting ScriptableObject field values, modifying material shader properties, or any task that results in direct changes to allowlisted Unity YAML asset files. Even for small edits or one-line…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Guide for directly editing Unity YAML-serialized asset files for Unity projects. ## Rules - **Edit only the following allowlist of simple YAML asset types.** Other YAML assets (`AnimationClip`, `AnimatorController`, `Texture2D`, `Mesh`, `AudioClip`, `LightingDataAsset`, etc.) carry binary-derived data or complex internal structure — open them in Unity Editor instead. - ScriptableObject (`MonoBehaviour`, class ID 114) — files `*.asset` - Material (`Material`, class ID 21) — files `*.mat` - **Never directly edit `.unity` or `.prefab` files.** Use `edit-scene` skill — those carry GameObject/Prefab-instance structure that is unsafe to author by hand. - **Never touch `.meta` files.** Unity owns `.meta` content (GUIDs, importer settings); hand-edits corrupt asset references project-wide. - **Preserve the mandatory two-line header exactly.** Lines 1–2 must be `%YAML 1.1` and `%TAG !u! tag:unity3d.com,2011:` — these are not stylistic, and Unity will fail to load the asset if they drift. - **Preserve the document marker.** `--- !u!<classID> &<fileID>` — for ScriptableObject use `--- !u!114 &11400000`, for Material use `--- !u!21 &2100000` (canonical local anchors). …

How to install
mdr add nowsprinting/unity-coding-skills/unity-yaml-editing-guide@sha256:705a6a857b60138fThe line at the top of this page pins the label git:20261016.6369daa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
