Quality

Content

65%

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

The body is highly actionable with complete, runnable code across many AWS serverless patterns, but it is verbose and monolithic. Splitting it into referenced files and adding a validated deploy workflow would lift its weaker dimensions.

Suggestions

Split large sections (Patterns, Sharp Edges, Validation Checks) into referenced files (e.g., PATTERNS.md, SHARP_EDGES.md) so SKILL.md becomes a navigable overview with one-level-deep references.

Add an explicit deployment workflow with a validation checkpoint (e.g., `cdk synth` / `sam validate` before `deploy`) and a validate->fix->retry feedback loop.

Remove redundancy: drop the verbatim description repetition at the top and consolidate the duplicated SnapStart guidance.

DimensionReasoningScore

Conciseness

Mostly efficient with concrete code, but ~1300 lines with redundancy (SnapStart shown twice, description repeated verbatim at top) and some explanation that could be tightened; not the lean 'every token earns its place' level 3.

2 / 3

Actionability

Provides fully executable SAM/CDK templates, working Lambda handlers in Node.js/Python, and concrete CLI commands (sam build/deploy, cdk synth) that are copy-paste ready.

3 / 3

Workflow Clarity

Patterns are labeled with 'When to use' and Sharp Edges give diagnose-fix flows, but deployment lacks an explicit validation checkpoint (e.g., validate/synth before deploy) and no validate->fix->retry loop, capping this at 2.

2 / 3

Progressive Disclosure

Content is well-sectioned but entirely monolithic in one ~1300-line file with no bundle files or one-level-deep references; content that should be split (e.g., patterns, sharp edges, validation checks) is inline, matching the 2 anchor.

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.

The description is specific and trigger-term-rich, clearly staking out an AWS serverless niche. Its main weakness is the absence of an explicit 'Use when' trigger clause, which caps completeness.

Suggestions

Add an explicit 'Use when...' clause naming common user phrasings (e.g., 'Use when building serverless APIs, event-driven functions, or deploying with SAM/CDK on AWS').

Mention when to delegate to adjacent skills in the description (e.g., GCP/Azure serverless) to reduce conflict risk further.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities ('Lambda functions, API Gateway, DynamoDB, SQS/SNS event-driven patterns, SAM/CDK deployment, and cold start optimization'), matching the multiple-specific-actions anchor rather than the partial single-domain anchor at 2.

3 / 3

Completeness

Clearly answers 'what' (building production-ready serverless apps on AWS with listed services) but provides no explicit 'Use when...' trigger clause, which caps completeness at 2 per the guideline.

2 / 3

Trigger Term Quality

Contains natural terms users actually say ('AWS', 'serverless', 'Lambda', 'API Gateway', 'DynamoDB', 'SQS/SNS', 'SAM/CDK') with good coverage; not just generic or overly-technical jargon, so it sits above the 2 anchor.

3 / 3

Distinctiveness Conflict Risk

Targets a clear AWS-serverless niche with distinct triggers and is unlikely to conflict with other skills; it is more specific than the overlapping-skill anchor at 2.
