75%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-engineered reference body: dense domain directives, a concrete MCP-driven workflow with validation, an implicit-parameter table, and an unusually well-signaled reference index. The main weaknesses are the absence of the referenced bundle files in the evaluated skill directory, no inline minimal blueprint example, and a small amount of loader/related-skills boilerplate.
Suggestions
Include the referenced files in the bundle (or trim the reference index to files that actually ship), since seven `references/*.md` paths are cited but none exist in the skill directory.
Inline one minimal executable example — a `NodeFactories` root JSON blueprint or a complete setup-function body — so the most common case is copy-paste ready without opening a reference file.
Add an explicit feedback loop after step 5 ("if `mps_mcp_check_root_node_problems` reports problems, fix them and re-check before rebuilding") to close the workflow's validation gap.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes competence ("The setup function runs **before** `newNode` is attached to the model... Use the `enclosingNode` implicit parameter"), with no explanation of concepts Claude already knows. However, the "Loading companion skills" paragraph is host-mechanics boilerplate, and the Related Skills and Reference Index sections partially overlap, so a few tokens could be trimmed. | 4 / 5 |
Actionability | Guidance is mostly executable: exact MCP tool names with parameters ("`mps_mcp_insert_root_node_from_json`", "`featureKind: "STATEMENTS"`", "`moduleName: "<lang>"`") and a concrete body pattern "`ifInstanceOf (sampleNode is <Concept> original) { newNode.<prop> = original.<prop>; ... }`". It falls short of fully copy-paste-ready because the complete JSON blueprint and full code examples are deferred to reference files rather than shown inline. | 4 / 5 |
Workflow Clarity | The five-step Common-Path Workflow is clearly sequenced with an explicit validation checkpoint ("Validate with `mps_mcp_check_root_node_problems`, rebuild the language, exercise in a sandbox") reinforced in Critical Directives. It lacks an explicit fix-and-re-validate retry loop — error recovery is delegated to `references/common-failures.md` — so it matches anchor 4 rather than 5. | 4 / 5 |
Progressive Disclosure | Structure is good: a "Start here — most common case" pointer plus per-file triggers ("Open `references/node-factories-and-triggers.md` when you need...") with one-level-deep, clearly signaled references. Scored against the actual bundle, however, none of the seven referenced `references/*.md` files exist in the bundle, so the navigation cannot be fully verified and the split cannot be confirmed as appropriately placed. | 4 / 5 |
