depsgraph-and-evaluated-data SKILL.md skillB
depsgraph-and-evaluated-data from tmhsdigital/blender-developer-tools is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Read the evaluated geometry the user actually sees through the dependency graph instead of raw obj.data: evaluated_depsgraph_get, evaluated_get, to_mesh and to_mesh_clear lifetimes. Use when the user writes an exporter, measurement or inspection script, reports that modifiers, shape keys, armatures or geometry nodes are missing from exported or measured geometry, or reads obj.data.vertices and gets the undeformed base mesh. Targets 5.2 LTS.
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
# Depsgraph and Evaluated Data
## Trigger
Use this skill when the user:
- Is writing an exporter, measurement script, or inspection tool
- Reports that "modifiers are missing from my export" or "the vertex positions don't match what I see"
- Mentions `evaluated_depsgraph_get`, `evaluated_get`, `to_mesh`, `to_mesh_clear`
- Reads from `obj.data.vertices` and gets unexpectedly raw geometry
- Needs final positions after armature deformation, shape keys, modifiers, or geometry nodes
## The core misunderstanding
`bpy.data.objects['Cube'].data.vertices` does not return what the user sees in the viewport. It returns the **mesh datablock as authored**, before any modifier, armature, shape key, or geometry nodes evaluation.
The viewport shows **evaluated** geometry: the result of running the full dependency graph. Anything that downstream code consumes (renderers, exporters, measurement tools) almost always wants the evaluated form, not the raw form.
```
authored mesh (obj.data)
|
v
modifier stack
shape keys
armature deform
geometry nodes
|
v
evaluated mesh (what you see)
```
## The canonical pattern

How to install
mdr add tmhsdigital/blender-developer-tools/depsgraph-and-evaluated-data@sha256:6f9d49b7b069fd42The line at the top of this page pins the label git:20261007.4636c25, 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.
