Quality

Content

96%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.

An exemplary instruction skill: token-efficient, fully actionable with concrete IR examples and generated-code mappings, and a clearly sequenced workflow with real validation commands and error-recovery feedback. The only structural nit is that the dense field/projection reference material is all inline with no external split.

Suggestions

Consider moving the full class-field and projection-step reference tables into a one-level-deep reference file (e.g., references/ir-fields.md), keeping SKILL.md to the workflow, decision framework, and a few key examples.

Optionally add a short 'Common patterns' cross-link to worked domain-map.json examples for new tools, so edge cases (acknowledgeSingle, find) don't need to be fully specified inline.

DimensionReasoningScore

Conciseness

The body is dense tables and examples with essentially no filler: no explanation of concepts Claude already knows, no library-choices digressions, no padded prose. Each section (arg routing, projections, cache) delivers rules and examples only, matching the lean anchor.

5 / 5

Actionability

Guidance is executable throughout: concrete JSON snippets for classes/bindings/cache, field→example tables showing exact generated code (e.g., `name: \`projects/${this.projectId}/screens/${screenId}\``), a decision framework keyed on real tool properties, and copy-paste validation commands plus a real diagnostic error example. Not below 5 on any identifiable gap.

5 / 5

Workflow Clarity

The pipeline is clearly sequenced (Inputs → Output → Designing Classes → Designing Bindings → Decision Framework → Validation) with explicit validation checkpoints: five runnable commands and a sample validation error that lists available properties, giving a concrete fix-and-retry feedback loop. The Decision Framework section doubles as a checklist for new tools.

5 / 5

Progressive Disclosure

Sections are well-organized with tables, callouts, and clear navigation; there are no nested or buried references and no orphaned bundle paths. Not a 5 because ~190 lines of dense IR reference (class-field table, arg routing, projection semantics) are all inlined in SKILL.md; the projection/arg-routing tables could plausibly live in a one-level-deep reference file to keep the overview leaner.

Description

87%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 tight, third-person description that answers both what and when with concrete trigger phrases and a distinct niche. It is comprehensive for its scope; only slightly broader enumeration of capabilities and a few extra synonyms would improve it.

DimensionReasoningScore

Specificity

Concrete actions are named — "Design the domain model for the Stitch SDK" and "mapping MCP tools to domain classes and bindings in domain-map.json" — with the output artifact identified. Not a 5 because coverage of the specific sub-activities (class design, binding design, projection/validation) is summarized rather than enumerated; not a 3 since more than 1-2 concrete actions are explicit.

4 / 5

Completeness

Both parts are explicit: what — "Design the domain model for the Stitch SDK… mapping MCP tools to domain classes and bindings in domain-map.json"; when — "Use when mapping MCP tools to domain classes and bindings in domain-map.json". Concrete trigger phrases and the pipeline-stage context make both unambiguous, matching the top anchor.

5 / 5

Trigger Term Quality

Natural terms users would say in this workflow appear: "domain model", "MCP tools", "domain-map.json", "Stage 2", "generation pipeline". Not a 5 because some synonymous phrasings (e.g., "IR", "intermediate representation", "tool schema mapping") are absent; not a 3 because keyword coverage goes well beyond the domain name.

4 / 5

Distinctiveness Conflict Risk

The triggers ("Stitch SDK", "domain-map.json", "Stage 2 of the generation pipeline") carve out a clear niche with minimal overlap risk. The only adjacency is the sibling stitch-sdk-development skill, but the explicit stage and artifact name disambiguate it.
