Discovery
82%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a solid description with a clear 'Use when' clause and good trigger term coverage for TypeScript-related queries. Its main weakness is that the 'what' portion is somewhat abstract ('apply modern TypeScript standards') rather than listing specific concrete actions the skill performs. The trigger terms are well-chosen and natural, making it easy for Claude to match user requests to this skill.
Suggestions
Add more specific concrete actions to the 'what' portion, e.g., 'Enforces strict typing, configures tsconfig compiler options, converts any-typed code to proper types, designs type-safe generics and utility types.'
Consider adding file extension triggers like '.ts', '.tsx' to catch additional natural user references.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (TypeScript standards) and mentions some areas (type safety, maintainability), but doesn't list specific concrete actions like 'define strict type guards', 'configure compiler options', or 'refactor any-typed code'. The actions are implied rather than enumerated. | 2 / 3 |
Completeness | Clearly answers both 'what' (apply modern TypeScript standards for type safety and maintainability) and 'when' (explicit 'Use when' clause listing specific trigger scenarios: working with types, interfaces, generics, enums, unions, or tsconfig settings). | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'types', 'interfaces', 'generics', 'enums', 'unions', 'tsconfig', 'TypeScript', 'type safety'. These cover a good range of terms a developer would naturally use when needing this skill. | 3 / 3 |
Distinctiveness Conflict Risk | While TypeScript-specific terms like 'tsconfig', 'generics', and 'enums' are fairly distinctive, the broad scope of 'types' and 'interfaces' could overlap with general coding skills or other language-specific type system skills. The phrase 'modern TypeScript standards' helps but doesn't fully eliminate overlap with general TypeScript development skills. | 2 / 3 |

Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, concise TypeScript patterns skill that efficiently communicates standards and anti-patterns without over-explaining. Its main weakness is that several bullet points are more descriptive labels than actionable instructions (e.g., 'Generics: Reusable, type-safe code' tells Claude what generics are for but not what to do). The verification step and progressive disclosure to reference files are strong points.
Suggestions
Expand terse descriptive bullets into actionable instructions with brief code examples, especially for generics, type guards, and discriminated union switch patterns (e.g., show a concrete type guard predicate function).
Replace label-style entries like 'Generics: Reusable, type-safe code' with specific guidance such as 'Use generics to parameterize container types and function signatures: `function parse<T>(raw: string): T`'.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. Every bullet point delivers actionable guidance without explaining what TypeScript is or how types work. No unnecessary preamble or padding—assumes Claude's competence throughout. | 3 / 3 |
Actionability | The code examples are executable and concrete, but most guidance is in terse bullet-point form (e.g., 'Generics: Reusable, type-safe code') that describes rather than instructs. More concrete examples for key patterns like type guards, discriminated union switch handling, or generic usage would improve actionability. | 2 / 3 |
Workflow Clarity | The verification step is explicit and specific—calling getDiagnostics via MCP tool after type changes that cross module boundaries. For a standards/patterns skill (not a multi-step destructive process), this level of validation guidance is appropriate and clear. | 3 / 3 |
Progressive Disclosure | Clean overview structure with well-signaled one-level-deep references to TESTING.md and REFERENCE.md for advanced content. Content is appropriately split between the main skill file and reference documents. | 3 / 3 |
