Implementation
38%This skill provides useful serverless patterns with concrete SAM templates and Lambda handler examples, but suffers from significant quality issues: truncated code blocks that are not executable, a completely broken Sharp Edges table, and no deployment workflow or validation steps. The skill description promises coverage of SAM/CDK deployment and cold start optimization, but the content doesn't deliver on these topics.
Suggestions
- Complete all truncated code blocks to make them fully executable - the Python handler, JavaScript get handler, and SQS processor all cut off mid-function
- Fix the Sharp Edges table - currently shows 'Issue' placeholders instead of actual issue names, and solutions are just section headers without content
- Add a deployment workflow section with explicit steps: sam build -> sam deploy -> validation/testing commands
- Add references to separate files for advanced topics mentioned in the description (CDK deployment, cold start optimization) or include that content
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is reasonably efficient with code examples, but includes some redundancy (both Node.js and Python versions for multiple patterns) and the code examples are truncated/incomplete, suggesting poor editing rather than intentional brevity. | 2 / 3 |
Actionability | Provides concrete code examples and SAM templates which is good, but multiple code blocks are truncated mid-function (e.g., Python handler cuts off at 'Parse i', JavaScript cuts off at 'const item ='), making them non-executable and incomplete. | 2 / 3 |
Workflow Clarity | No deployment workflow or validation steps are provided. The skill shows patterns but doesn't explain how to deploy, test, or validate the serverless application. Missing critical steps like 'sam build', 'sam deploy', or how to verify the deployment succeeded. | 1 / 3 |
Progressive Disclosure | Content is organized into logical sections (Patterns, Anti-Patterns, Sharp Edges) but the Sharp Edges table is malformed with 'Issue' repeated instead of actual issue names. No references to external files for deeper topics like cold start optimization or CDK deployment mentioned in the description. | 2 / 3 |

83%This is a strong description with excellent specificity and trigger term coverage for AWS serverless development. The main weakness is the absence of an explicit 'Use when...' clause, which would help Claude know exactly when to select this skill over others. The technical depth is appropriate and the scope is well-defined.
Suggestions
- Add a 'Use when...' clause with explicit triggers like 'Use when building serverless applications, deploying to AWS Lambda, or working with API Gateway, DynamoDB, or event-driven architectures.'
- Consider adding common user phrasings like 'deploy to Lambda', 'serverless API', or 'AWS backend' to capture more natural request patterns.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions and technologies: Lambda functions, API Gateway, DynamoDB, SQS/SNS event-driven patterns, SAM/CDK deployment, and cold start optimization. These are specific, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers 'what does this do' with specific AWS serverless capabilities, but lacks an explicit 'Use when...' clause or equivalent trigger guidance. The when is only implied through the technology names. | 2 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'serverless', 'AWS', 'Lambda', 'API Gateway', 'DynamoDB', 'SQS', 'SNS', 'SAM', 'CDK', 'cold start'. These cover common terminology developers use when discussing serverless architecture. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear AWS serverless niche. The specific combination of Lambda, API Gateway, DynamoDB, and deployment tools (SAM/CDK) creates a unique fingerprint unlikely to conflict with general coding or other cloud skills. | 3 / 3 |
