Quality

Content

87%

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

A well-structured, highly actionable patterns catalog with lean code examples, held back only by the absence of an explicit validation-gated workflow sequence.

Suggestions

Add a short end-to-end build/verify workflow (e.g., bootstrap → validate env → run tests → start) with an explicit validation checkpoint to lift workflow_clarity.

Include a concrete feedback loop for risky operations like transactions or env validation (e.g., fail boot and report missing vars) so error recovery is explicit.

DimensionReasoningScore

Conciseness

The body is lean and pattern-focused: section headers, executable code blocks, and terse bullet rules, with no padding explaining what NestJS or basic TypeScript concepts are; every token earns its place.

3 / 3

Actionability

It provides multiple complete, copy-paste-ready examples (bootstrap, module/controller/service, DTO, guards, exception filter, test setup) plus concrete executable guidance, not pseudocode.

3 / 3

Workflow Clarity

Sections follow a sensible logical order (When to Activate → structure → bootstrap → production defaults), but there is no explicit sequenced multi-step workflow with validation checkpoints, and the testing section lacks a validate-fix-retry loop.

2 / 3

Progressive Disclosure

With no bundle files present, the skill is a single self-contained SKILL.md organized into clear, well-signaled sections with no nested references, which qualifies for a top score per the simple-skill guideline.

Description

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.

A concise, specific NestJS description with strong trigger terms and a clear niche, weakened only by the absence of an explicit "Use when..." trigger clause.

Suggestions

Add an explicit trigger clause such as 'Use when building or refactoring NestJS APIs, modules, controllers, providers, guards, or interceptors.' to fully answer the 'when' question.

Mention common user phrasings like 'NestJS services' or 'Nest modules' to broaden natural keyword coverage slightly.

DimensionReasoningScore

Specificity

The description enumerates concrete architectural elements ("modules, controllers, providers, DTO validation, guards, interceptors, config") plus the target ("production-grade TypeScript backends"), listing multiple specific actions rather than vague language.

3 / 3

Completeness

It clearly states what the skill does, but lacks any "Use when..." clause or equivalent explicit trigger guidance, so per the rubric guideline completeness is capped at 2.

2 / 3

Trigger Term Quality

It uses natural terms a user would actually say ("NestJS", "TypeScript backends", "controllers", "providers", "guards", "DTO validation", "interceptors") with good coverage of common phrasings.

3 / 3

Distinctiveness Conflict Risk

It targets a clear niche (NestJS-specific architecture) with distinct triggers unlikely to overlap with other skills' descriptions.
