Quality

Content

100%

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

The content is a tight, high-signal reference packed with executable commands and concrete patterns, well-organized into focused sections without padding. It assumes Claude's competence and avoids explaining basic WebAssembly concepts.

DimensionReasoningScore

Conciseness

The body is a lean, bullet-driven reference that assumes Claude already knows what WebAssembly is and skips basic concept explanations; every line (e.g., 'WebAssembly.instantiateStreaming(fetch("module.wasm"), importObject)') earns its place, matching the 'Lean and efficient; assumes Claude's competence' anchor.

3 / 3

Actionability

It gives fully executable, copy-paste-ready commands and APIs such as 'wasm-pack build --target web', 'cargo build --target wasm32-wasi', 'wasm-opt -Oz', and 'wasm-tools compose', matching the 'Fully executable code/commands; specific examples' anchor.

3 / 3

Workflow Clarity

This is a well-organized reference/knowledge skill (under 50 lines) rather than a procedural one, and its sections (Principles, Techniques, Common Patterns, Pitfalls) are clearly structured; per the simple-skill scoring note, well-organized single-purpose content can score 3 without explicit multi-step workflows.

3 / 3

Progressive Disclosure

The skill is a single self-contained file with no external bundle directories and no need for separate references; per the guideline that skills under 50 lines with no need for external references can score 3 via well-organized sections alone, the clear section structure satisfies this.

Description

50%

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 is specific about the WebAssembly domain but omits any 'Use when...' trigger clause, capping completeness and weakening trigger-term and distinctiveness scores. It reads as a capability statement rather than activation guidance.

Suggestions

Add a 'Use when ...' clause naming natural triggers (e.g., 'Use when compiling Rust or C to WebAssembly, building WASI modules, composing components with WIT, or integrating Wasm in the browser').

Include common user-facing phrasings like 'wasm', 'compile to wasm', and 'WIT interfaces' alongside the current jargon to broaden trigger-term coverage.

Add a concrete action verb list (compile, optimize, compose, integrate) to lift specificity from a domain label to enumerated capabilities.

DimensionReasoningScore

Specificity

The description names the domain ('WASI, component model, Rust/C compilation, and browser integration') and implies actions like compilation, but it does not list multiple concrete actions, matching the 'Names domain and some actions, but not comprehensive' anchor rather than the multi-action level-3 example.

2 / 3

Completeness

It states what the skill does but provides no 'Use when...' or equivalent trigger clause, so per the judging guidelines completeness is capped at 2 ('Has what, but when is missing or only implied').

2 / 3

Trigger Term Quality

It includes natural terms a user would say ('WebAssembly', 'WASI', 'Rust/C compilation', 'browser integration'), but lacks common variations like 'wasm' or 'compile to wasm', fitting 'Some relevant keywords but missing common variations' rather than full level-3 coverage.

2 / 3

Distinctiveness Conflict Risk

The WebAssembly/WASI niche is reasonably distinct and unlikely to conflict with most skills, but the absence of explicit trigger guidance leaves it relying on domain specificity, matching 'Somewhat specific but could still overlap with similar skills' rather than the fully-distinct level-3 anchor.
