mps-aspect-editor-menus-and-keymaps

Use when authoring the **non-layout** parts of the MPS editor aspect — what happens when the user types, presses a key, triggers completion, pastes, or invokes a context action. Covers action maps (`CellActionMapDeclaration`), cell keymaps (`CellKeyMapDeclaration`), transformation menus (`TransformationMenu_Default` / `_Named` / `_Contribution`), substitute menus (`SubstituteMenu_Default` / `SubstituteMenu` / contributions), side transforms (LEFT/RIGHT), legacy cell menus, paste wrappers and copy-paste handlers (in the actions language), completion styling, reference presentation, two-step deletion, and the editor selection API. Trigger terms: `actionMap`, `keyMap`, `delete_action_id`, `transformationMenu`, `substituteMenu`, `Ctrl+Space`, `Ctrl+Alt+B`, side transform, paste wrapper, completion styling, `PasteWrappers`, `CopyPasteHandlers`. For the **layout** side (cells, layouts, style sheets) use `mps-aspect-editor` instead.

Quality

Content

100%

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

A well-structured reference skill body: lean and dense, highly actionable with concrete tool calls and role names, a sequenced workflow with validation checkpoints, and an exemplary one-level-deep reference index. It avoids concept re-explanation and splits detail across real bundle files.

DimensionReasoningScore

Conciseness

The body is dense and assumes MPS competence — no padded explanations of what MPS or menus are — with every directive and index entry earning its place; it respects the token budget.

3 / 3

Actionability

Provides concrete, executable guidance: specific MCP tool calls (`mps_mcp_insert_root_node_from_json`, `mps_mcp_check_root_node_problems`), exact role names (`conceptDeclaration`, `applicableConcept`, `sections`), naming conventions, and smodel idioms rather than abstract direction.

3 / 3

Workflow Clarity

The nine-step Common-Path Workflow is clearly sequenced with explicit validation/rebuild checkpoints (steps 6–7: rebuild language, `mps_mcp_check_root_node_problems` on every touched root) and a diagnose step, giving a feedback loop for error recovery.

3 / 3

Progressive Disclosure

The body acts as a concise overview/index pointing to 15 real, one-level-deep reference files (all verified present under references/), each entry clearly signaled with an 'Open X when...' trigger, with detail appropriately split out rather than inlined.

Description

100%

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-triggered description that clearly delineates the non-layout MPS editor aspect scope and disambiguates it from the layout skill. It covers what, when, and the boundary with sibling skills concisely.

DimensionReasoningScore

Specificity

Lists multiple concrete artefact types and behaviours (action maps `CellActionMapDeclaration`, cell keymaps `CellKeyMapDeclaration`, transformation/substitute menus, side transforms, paste wrappers, completion styling, two-step deletion) rather than vague language.

3 / 3

Completeness

Explicitly answers both 'what' (the non-layout editor-aspect artefacts it covers) and 'when' via the opening 'Use when authoring...' clause plus a redirect for the layout side, satisfying the explicit-trigger requirement.

3 / 3

Trigger Term Quality

Includes a dense set of natural and technical trigger terms users would say (`Ctrl+Space`, `Ctrl+Alt+B`, side transform, paste wrapper, completion styling, `PasteWrappers`, `CopyPasteHandlers`, `actionMap`, `keyMap`), with good coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

Carves a clear non-layout niche with distinct triggers and explicitly routes the layout side to `mps-aspect-editor`, making conflict with sibling skills unlikely.
