Blender Context Errors — Diagnosis and Resolution
Purpose
This skill enables diagnosis and resolution of Blender Python context errors. Context errors are the most common category of Blender scripting failures. They occur when code accesses bpy.context members or calls bpy.ops operators in situations where the required context is unavailable, restricted, or incorrectly configured.
Scope
- RuntimeError from restricted context access (handlers, timers, draw callbacks)
- Operator
poll()failures and incorrect context forbpy.opscalls - Context override removal in Blender 4.0+ and
temp_override()migration - Modal operator context issues
- Context-dependent attribute access (
bpy.context.active_object,bpy.context.edit_object) - Stale references after undo, data modification, or mode changes
Version coverage: Blender 3.x, 4.x, 5.x. Version-breaking changes are marked explicitly.
Dependencies: This skill builds on blender-core-api (context system basics) and blender-syntax-operators (operator patterns).

blender-core-api
Guides Blender Python API usage including bpy module structure, RNA data access, context system, dependency graph, and operator invocation. Activates when writing bpy scripts, creating Blender addons, or accessing Blender data blocks programmatically.
1blender-syntax-panels
Defines Blender UI panel creation including bpy.types.Panel, draw() method, UILayout API (row/column/box/split), bl_space_type, bl_region_type, bl_category, sub-panels, draw_header, menus, and UIList. Activates when creating custom Blender panels, building addon interfaces, or working with UILayout elements.
1ifcos-syntax-api
Documents the ifcopenshell.api module system with all 30+ API modules, invocation patterns via api.run() and direct module calls, parameter conventions, and module categorization. Activates when creating IFC entities, modifying properties, managing spatial structure, or using any ifcopenshell.api function.
1bonsai-impl-bcf
Guides implementation of BIM Collaboration Format (BCF) workflows in Bonsai including creating BCF topics, adding viewpoints with camera snapshots, managing comments, importing/exporting BCF files (v2.1 and v3.0), and integrating BCF issue tracking with IFC element references. Activates when working with BCF files, BIM issue tracking, clash report management, or collaboration workflows in Bonsai.
1ifcos-impl-mep
Guides MEP (Mechanical, Electrical, Plumbing) modeling in IFC using ifcopenshell.api.system including IfcSystem, IfcDistributionElement, ports, connections, flow segments, fittings, and MEP-specific property sets. Activates when creating HVAC systems, piping networks, electrical circuits, or MEP elements in IFC models.
1ifcos-impl-cost
Guides IFC cost management using ifcopenshell.api.cost including cost schedules, cost items, cost values, cost quantities, and 5D BIM workflows. Activates when implementing cost estimation in IFC models, creating cost schedules, or linking quantities to cost items.
