NIH grant research skill for clinical researchers. Grill-me intake (research idea + career stage + preliminary data + environment + submission posture + known institute targets) locks down the funding strategy before any search runs. Runs a 5-facet Consensus positioning analysis (with draft Significance/Innovation language), maps the research to the right NIH institutes and study sections via RePORTER, finds NOSIs and funded overlap, and produces an editable Word document (.docx) with budget/scope-aware mechanism recommendations, submission timelines, and a mandatory program officer recommendation. Use when the user asks about research funding or makes any grant-related request (e.g., 'grants for [topic]', 'find grants for my research idea', 'what grants match my research', 'help me find NIH funding', 'grant opportunities for my research'). NIH-only scope — non-NIH funders (PCORI, DOD CDMRP, VA, foundations) are out of scope and flagged at intake.

Use when reviewing, validating, or auditing Blender Python code for correctness. Runs systematic checks for deprecated API usage, context errors, version compatibility issues, threading violations, data reference invalidation, incorrect operator calls, and addon structure compliance. Prevents shipping code with silent version-dependent failures. Keywords: code review, validation, audit, deprecated API, context error, version compatibility, threading, addon structure, code quality, Blender Python, my addon has errors, check my code, why does my script fail.

Use when migrating, porting, or upgrading Blender Python scripts and addons across major versions (3.x to 4.x to 5.x). Provides a systematic migration process covering API renames, removed functions, changed parameters, extension system migration, BGL to GPU module conversion, and bone collection migration. Prevents incomplete migrations that compile but fail at runtime. Keywords: migration, porting, upgrade, version, 3.x to 4.x, 4.x to 5.x, API rename, bgl to gpu, extension migration, bl_info to manifest, bone collection, script stopped working after update, upgrade addon to new Blender.

Use when writing Blender Python scripts that access bpy module structure, RNA data, the context system, dependency graph, or operator invocation. Prevents the common mistake of accessing context attributes outside their valid scope or calling operators without checking poll(). Covers bpy.data, bpy.context, bpy.ops, depsgraph evaluation, and RNA property access patterns across Blender 3.x/4.x/5.x. Keywords: bpy, Blender Python, RNA, context, depsgraph, operator, bpy.data, bpy.ops, how to start scripting Blender, Blender Python basics, access objects in scene, get selected object.

Use when drawing custom overlays, viewport visualizations, or offscreen renders in Blender Python.

Use when implementing end-to-end BIM workflows that combine IfcOpenShell, Bonsai, and Blender -- such as IFC creation from scratch, model enrichment, validation pipelines, geometry extraction, or batch processing of building models. Prevents the common mistake of skipping unit and context setup before creating geometry, or directly modifying IFC attributes instead of using ifcopenshell.api.run(). Covers property set management across tools, spatial hierarchy patterns, and version compatibility for IFC2X3/IFC4/IFC4X3. Keywords: BIM workflow, IFC creation, model validation, property extraction, batch processing, spatial hierarchy, cross-technology, IfcOpenShell Bonsai Blender, pset management, how to create IFC model, step by step BIM, get properties from IFC.

Use when writing Blender Python code that must work across multiple versions (3.x/4.x/5.x), or when migrating scripts between Blender versions. Prevents breakage from renamed APIs, removed modules (bgl in 5.0), and changed function signatures. Provides the complete breaking changes matrix, deprecation timeline, and version-safe coding patterns. Keywords: Blender version, migration, deprecated, breaking change, bgl removal, bpy.app.version, version compatibility, 3.x, 4.x, 5.x, API changes, which Blender version, what changed in Blender 4.

GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server.

Use when debugging Blender ReferenceError from removed objects, undo-invalidated bpy.data references, or stale ID pointers. Prevents the common crash of caching bpy.data references across undo/redo operations (references become invalid). Covers safe data access patterns, ID reference caching pitfalls, data lifecycle management, and bpy.data collections. Keywords: ReferenceError, undo, stale reference, bpy.data, ID pointer, data invalidation, removed object, data lifecycle, StructRNA, Blender crash, object disappeared after undo, StructRNA has been removed.

Use when debugging Blender AttributeError from removed APIs, ImportError from deprecated modules (bgl in 5.0), or breaking changes in operator signatures between versions. Prevents silent failures from using APIs that were renamed or removed in newer Blender versions. Provides migration patterns from 3.x to 4.x to 5.x with complete replacement mappings. Keywords: AttributeError, ImportError, deprecated, version error, bgl, migration, breaking change, removed API, 3.x to 4.x, 4.x to 5.x, Blender upgrade, module has no attribute, addon not compatible.

Use when automating Blender workflows -- batch rendering, headless processing via blender --background, file format conversion, or pipeline integration.

Keywords: construction animation, camera walkthrough, solar study, phasing, NLA, keyframe, construction sequence, visibility animation, AEC visualization, animate building, show build sequence, camera fly-through.

Create advanced animations with GSAP. Use when building complex timelines, scroll-driven animations, SVG morphing, text animations, or high-performance web animations beyond CSS capabilities.

Academic literature orientation skill that searches papers via free keyless APIs (PubMed E-utilities + OpenAlex) by default — with the Consensus MCP as an optional enhancement lane when connected — builds a strategic search plan using PICO (default) or SPIDER / Decomposition / hybrid as fallbacks, and synthesizes findings into a formatted Word (.docx) research guide. Grill-me intake (research question specificity + framework hint + tentative depth) before the recon search; a second forcing checkpoint after Phase 2 confirms framework + sub-areas + depth before searches consume budget. Configurable depth (5/10/20 queries) controls coverage vs. speed. Output is a 'launching pad' — an orientation guide that lets a researcher dive in confidently, not a finished review. Use when the user starts literature-oriented research (e.g., 'litreview on [topic]', 'literature review on [topic]', 'I'm starting a literature review on X', 'I'm writing a paper on X', 'help me research X', 'I'm doing research on X', 'can you help me research X'). Do NOT use for single one-off paper searches wanting a quick list — that's a plain PubMed/OpenAlex (or Consensus) query.

Use when creating or modifying Blender materials and shader nodes via Python. Prevents the breaking change of using old Principled BSDF input names (e.g., "Subsurface" renamed to "Subsurface Weight" in 4.0). Covers material creation, node tree setup, Principled BSDF input mapping, UV assignment, texture loading, and material slot management. Keywords: material, shader, Principled BSDF, node tree, texture, UV map, material_slot, ShaderNodeBsdfPrincipled, node links, Blender materials, assign material to object, create material from code, change color.
