Content

85%

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

This is a well-structured, concise conventions skill that efficiently communicates project-specific TypeScript rules and branded type mappings. Its main weakness is the lack of concrete code examples showing correct usage patterns (e.g., a before/after example of branded type usage or the function declaration preference). The reference table is an excellent format for the branded types information.

Suggestions

Add a brief code example showing correct branded type usage (e.g., `const id: VertexId = createVertexId(rawString)` vs incorrect `const id: string = rawString`)

Add a concrete example contrasting the preferred named function syntax with the discouraged arrow function pattern at module level

DimensionReasoningScore

Conciseness

The content is lean and efficient. It avoids explaining what branded types are conceptually (Claude already knows) and instead provides a direct reference table of types, creator functions, and locations. The brief intro sentence is justified as project-specific context. Every token earns its place.

3 / 3

Actionability

The branded types table is concrete and useful as a reference, and the general rules are specific. However, there are no executable code examples showing correct vs incorrect usage of branded types, and no example of the named function syntax preference in context. The guidance is specific but not fully copy-paste ready.

2 / 3

Workflow Clarity

This is a conventions/reference skill rather than a multi-step workflow skill. The single-purpose nature (TypeScript conventions) is clearly communicated with unambiguous rules. No destructive or batch operations are involved, so no validation checkpoints are needed.

3 / 3

Progressive Disclosure

For a simple, focused conventions skill under 50 lines with no need for external references, the content is well-organized with clear sections (General Rules, Branded Types) and a well-structured table. No bundle files are needed for this scope.

Description

32%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description identifies its domain (TypeScript conventions for Graph Explorer) and mentions a few specific pattern categories, but lacks concrete actions and completely omits trigger guidance. It reads more like a topic label than a skill description that would help Claude distinguish it from other TypeScript or coding convention skills.

Suggestions

Add an explicit 'Use when...' clause, e.g., 'Use when writing or reviewing TypeScript code in the Graph Explorer project, or when the user asks about coding conventions, type patterns, or style rules for Graph Explorer.'

List specific concrete actions the skill enables, such as 'Enforces branded type patterns, applies function declaration style rules, validates type-safe API boundaries, and reviews code for convention compliance.'

Include natural trigger terms users might say, such as 'code style', 'coding standards', 'TS conventions', 'type patterns', or 'code review' to improve discoverability.

DimensionReasoningScore

Specificity

Names the domain (TypeScript/Graph Explorer) and some actions (branded types, function style preferences, type safety patterns), but these are more like categories than concrete actions. It doesn't list specific things the skill does, like 'enforce branded type usage' or 'convert interfaces to type aliases'.

2 / 3

Completeness

Describes what the skill covers at a high level but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per rubric guidelines, a missing 'Use when...' clause should cap completeness at 2, and the 'what' is also weak, so this scores a 1.

1 / 3

Trigger Term Quality

Includes relevant keywords like 'TypeScript', 'branded types', 'type safety', and 'Graph Explorer', but misses common variations users might say such as 'coding conventions', 'style guide', 'linting rules', 'TS patterns', or 'code review'.

2 / 3

Distinctiveness Conflict Risk

The mention of 'Graph Explorer' provides some specificity, but 'TypeScript conventions and rules' could overlap with general TypeScript coding skills or other project-specific convention skills. The branded types mention adds some distinctiveness.
