mps-aspect-editor

Use when creating or changing MPS editor definitions — the overall workflow from scaffolding a `ConceptEditorDeclaration` through componentizing reusable `EditorComponentDeclaration`s, refining cell models and cell layouts, applying style sheets and indent-layout style items, wiring smart references, leveraging inheritance via super-concepts and interfaces, inspecting (`print_node_json`, `show_node_representation`) and validating (`check_root_node_problems`). Covers `jetbrains.mps.lang.editor` cell models (`CellModel_RefNode`/`CellModel_RefNodeList`/`CellModel_RefCell`/`CellModel_Property`/`CellModel_Constant`), layout choices, and JSON blueprints for common editor shapes. For the non-layout side (action maps, keymaps, transformation/substitute menus) use `mps-aspect-editor-menus-and-keymaps`.

Quality

Content

71%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.

A dense, actionable reference body with a clear validated workflow and strong progressive-disclosure intent. Its main weakness is that every referenced bundle file (references/cell-models.md, indent-layout-styles.md, editor-patterns.md, editor-components.md, stylesheet-values.md) is missing, so the carefully signaled navigation leads nowhere.

Suggestions

Ship the five referenced files under references/ so the Reference Index links resolve; otherwise inline the most critical JSON blueprint (the minimal ConceptEditorDeclaration template) directly in the body.

Add an explicit validate→fix→re-validate feedback loop to the Common Workflow so the validation checkpoint matches the destructive/batch-operation standard.

Confirm the cross-skill relative link ../mps-mcp-workflow/references/aspect-model-stereotypes.md resolves, since the body depends on it for the create-model path.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's MPS knowledge — directives like 'Always use CellModel_RefNodeList for 0..n or 1..n children' earn their place without explaining basics. Only the dense empty-state directive could be tightened slightly, placing it just below a perfect 5.

4 / 5

Actionability

Gives concrete, executable guidance — exact style-class item names, readOnly flags, and specific MCP tool calls (mps_mcp_scaffold_editor, mcp_print_node, mcp_check_root_node_problems). It falls short of 5 only because the copy-paste JSON blueprints live in the references rather than inline in the body.

4 / 5

Workflow Clarity

A clear numbered sequence (step 0 check existence through step 5 validate) with an explicit validation checkpoint via mcp_check_root_node_problems. Not a 5 because the error-recovery feedback loop ('if validation fails, fix and re-validate') is only weakly implied rather than spelled out.

4 / 5

Progressive Disclosure

The structure is well-signaled with a one-level-deep Reference Index pointing to five references/*.md files, but none of those bundle files actually exist, so navigation is broken — this matches 'references present but not clearly signaled / could be better organized' when scored against the actual bundle.

Description

85%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.

A highly specific, well-scoped description that clearly states both what it does and when to use it, with strong boundary guidance against a sibling skill. Its only weakness is trigger-term naturalness: the bulk of the text is internal MPS jargon rather than phrases a user would naturally utter.

Suggestions

Lead with a few more user-natural trigger phrases (e.g. 'edit the projectional editor for an MPS concept', 'change how a concept is displayed') before the concept-identifier enumeration.

Add common synonyms or phrasings a user might say ('editor aspect', 'cell layout') to broaden natural keyword coverage.

DimensionReasoningScore

Specificity

Enumerates many concrete actions (scaffolding, componentizing, refining cell models/layouts, applying style sheets, wiring smart references, inspecting, validating) and names specific cell-model concepts, giving comprehensive coverage rather than vague abstraction.

5 / 5

Completeness

Explicitly answers both 'what' (the enumerated workflow and covered cell models) and 'when' ('Use when creating or changing MPS editor definitions') with concrete trigger phrasing, plus a scope boundary to a sibling skill.

5 / 5

Trigger Term Quality

Has the natural phrase 'creating or changing MPS editor definitions' but is otherwise dominated by internal concept identifiers users would not naturally say, with no synonyms or file extensions — matching 'some relevant keywords but missing common variations'.

3 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (the layout/projectional-editor side of MPS) and explicitly routes the non-layout side to 'mps-aspect-editor-menus-and-keymaps', minimizing conflict risk.
