Jev in Blender — operator search

A Blender extension (4.2+) that adds a Jev tab to the 3D Viewport sidebar, opened with N. Type what you want to do in plain language, press Enter, and TypeSafe's Jev ranks every registered bpy.ops operator against the request; click a result to run it, or copy its bpy.ops call.

Blender exposes roughly 2,500 operators and a Choice question holds at most 255 options, so the search is hierarchical: first a Choice over bpy.ops modules with hand-written descriptions, then Choices over ≤250-operator chunks for the top-3 modules in one request, each carrying a none_of_these option. Results combine P(module) · P(op | chunk).

The README estimates 5–15k input tokens for a hierarchical search, about $0.0005 at jev-1.13 pricing. A flat strategy skips the module stage and ranks every operator in one request — fewer round trips but roughly 4x the tokens.

Symlink jev_operator_search into Blender's extensions user_default directory, then use Edit › Preferences › Get Extensions › refresh local, enable Jev Operator Search, and paste a key from console.typesafe.ai. The key saves when you confirm the field into config.json (mode 600), survives reinstalls, and TYPESAFE_API_KEY is the fallback.

Yes — the request state includes a summary of the current Blender context: mode, active object type, selection count and editor. That is why 'delete' can resolve to mesh.delete in Edit Mode and object.delete in Object Mode, and modules are only expanded until their combined probability reaches 0.9.

Yes: export TYPESAFE_API_KEY and run `blender -b --factory-startup --python scripts/test_search.py -- "bevel the selected edges" "add a cube"`. To build a distributable zip, run `blender --command extension build --source-dir jev_operator_search`.

It ranks and executes existing bpy.ops operators; it does not write new scripts or edit scenes beyond the operator you pick. It needs a TypeSafe key and network access, and the README shows demo videos rather than published accuracy benchmarks.
