Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is a well-structured, executable skill body: tight code, clear sequenced workflow with verification, and clean one-level-deep references. Only minor conciseness trim is possible.

DimensionReasoningScore

Conciseness

The body is lean, defers detail to references, and assumes Blender/bpy competence; minor padding (the restated intro and the inline Pitfalls duplicating references/pitfalls.md) keeps it just below anchor 5.

4 / 5

Actionability

It provides copy-paste-ready bpy snippets (clear scene, add mesh, material, keyframe, render), exact CLI commands, and a concrete tool table covering the common cases, matching anchor 5.

5 / 5

Workflow Clarity

The numbered Procedure has explicit validation checkpoints (get_scene_info first, screenshot between steps, render to absolute path and report) plus error-recovery guidance and a dedicated Verification section, matching anchor 5.

5 / 5

Progressive Disclosure

The body is a clear overview with a well-signaled one-level-deep reference table (bpy-api.md, recipes.md, pitfalls.md, all verified present), organized by topic for easy navigation, matching anchor 5.

Description

56%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is distinctive and correctly names its domain, but it is thin on concrete actions and lacks any "Use when" trigger guidance, which caps completeness and trigger coverage.

Suggestions

Add a "Use when..." clause naming natural triggers (e.g., "Use when the user wants to create or modify meshes, materials, lighting, animation, or renders in a running Blender instance").

Replace the generic "Drive Blender" with 2-3 concrete actions (e.g., "Create and modify meshes, materials, and animations in a live Blender session via the blender MCP").

Include common synonyms/extensions users say (3D, rendering, modeling, animation) so the description matches natural phrasing.

DimensionReasoningScore

Specificity

It names the domain (Blender, MCP, bpy) but offers only one generic action verb ("Drive"); "recipes" is a noun, not a concrete action, so it lands at anchor 2 rather than the 1-2-action anchor 3.

2 / 5

Completeness

It gives a clear "what" (drive Blender via MCP with bpy recipes) but no "Use when"/trigger clause, so per the missing-trigger cap it stays at anchor 3 rather than 4.

3 / 5

Trigger Term Quality

"Blender", "bpy", and "MCP" are terms a Blender user would say, but it omits common natural variations (3D, modeling, animation, rendering) that the skill actually covers, fitting anchor 3 over 4.

3 / 5

Distinctiveness Conflict Risk

The narrow phrasing "Blender via the catalog blender MCP, with bpy recipes" carves a distinct niche with minimal overlap risk against any other skill, matching anchor 5.
