mps-language-inheritance

Investigate inheritance between MPS languages and between concepts — extended languages, superconcepts, implemented interfaces, sub-/assignable concepts, and cross-language specialization. Use when tracing language hierarchies, finding extension points, or checking concept assignability.

Quality

Content

93%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 tight, highly actionable reference skill that maps each inheritance question to exact MPS tools, enums, and response fields with minimal padding. The only soft spot is the absence of explicit validation/feedback steps, though none are strictly required for read-only operations.

DimensionReasoningScore

Conciseness

The body is lean and tool-name-dense, assuming Claude's MPS knowledge; it avoids explaining what MPS/concepts are and every section earns its tokens with actionable specifics. Only one or two orienting sentences are mildly trimmable, not enough to drop from the lean anchor.

5 / 5

Actionability

Guidance is fully actionable via exact tool names (`mps_mcp_get_project_structure`, `mps_mcp_query_structure`), specific enum values (`GET_ALL_SUPERCONCEPTS`, `IS_SUBCONCEPT_OF`), and concrete response fields (`extendedLanguages`, `superConcept`, `languageReference`) — Claude knows precisely what to call and read.

5 / 5

Workflow Clarity

Tasks are clearly sequenced by question type with a numbered module-level procedure and a Best-Practice recommended order, but there are no explicit validation/feedback-loop checkpoints; this is acceptable for a read-only investigation skill yet caps below the anchor that requires explicit validation steps.

4 / 5

Progressive Disclosure

The body is under 50 lines, needs no bundle files, and is organized into well-signaled sections (Critical Directives, Module-Level, Concept-Level, Strategic Analysis, Best Practice, Related Skills) with one-level-deep cross-skill references — matching the simple-skill exception for a clean reference structure.

Description

92%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 strong, well-scoped description that concretely lists the inheritance capabilities and provides explicit "Use when..." trigger guidance tied to natural MPS user phrasing. The only minor gap is a lack of synonym/variant trigger terms.

DimensionReasoningScore

Specificity

The description names the domain and enumerates multiple concrete capabilities — "extended languages, superconcepts, implemented interfaces, sub-/assignable concepts, and cross-language specialization" — giving comprehensive coverage of the inheritance investigation surface.

5 / 5

Completeness

It explicitly answers both what ("Investigate inheritance between MPS languages and between concepts — ...") and when ("Use when tracing language hierarchies, finding extension points, or checking concept assignability.") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Natural trigger phrases are present ("tracing language hierarchies", "finding extension points", "checking concept assignability") that an MPS user would say, but coverage lacks synonyms/variants beyond the core MPS-specific terms.

4 / 5

Distinctiveness Conflict Risk

The MPS + concept-inheritance niche is sharply scoped with distinctive triggers, and the body even delineates adjacent skills, so conflict risk with other skills is minimal.
