aws-sdk-js-v3-usage

AWS SDK for JavaScript v3 development patterns. Use when writing JavaScript or TypeScript code that uses AWS services via @aws-sdk/* packages (aws-sdk-js-v3), or when asked about schemas, runtime validation, serialization, or code generation in the context of the JS/TS AWS SDK.

Quality

Content

87%Weight 40%Scale 1-5

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

Excellent, lean, highly actionable reference skill with strong progressive disclosure to real bundle files. The only gap is the absence of explicit validation/verification checkpoints for batch and destructive operations, which caps workflow clarity.

Suggestions

Add an explicit verify/validate step after destructive or batch operations (e.g. confirm a PutCommand succeeded before continuing, or validate an Upload.done() result) to lift workflow clarity above the cap.

Include a short validate→fix→retry feedback loop in the error-handling section rather than only a catch-and-log example.

DimensionReasoningScore

Conciseness

The body is lean: each section is a short directive plus one tight executable example, with no concept lectures, library-comparison chatter, or padding; every token earns its place and it assumes Claude's competence.

5 / 5

Actionability

Every section provides copy-paste-ready, executable code covering the common cases (client construction, credentials, streams, paginators, DynamoDB DocumentClient, S3 presigned/multipart/waiters, error handling, middleware, abort, Lambda, SigV4a).

5 / 5

Workflow Clarity

Each topic gives an unambiguous single action, but batch/destructive-adjacent operations (DynamoDB writes, S3 multipart upload, streaming under socket limits) lack explicit validate/verify checkpoints or error-recovery feedback loops in the body, which caps workflow clarity at 3 per the rubric guidance.

3 / 5

Progressive Disclosure

The body is a clear overview that splits detailed material into 11 one-level-deep references/*.md files, each clearly signaled ("For … → see references/x.md"); all referenced paths resolve to real bundle files, making navigation easy.

Description

68%Weight 40%Scale 1-5

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 has strong, explicit trigger guidance and a clear, low-conflict niche, but its capability statement is generic ("development patterns") and the concrete actions live only in the when-clause. Tightening the "what" into specific capabilities would raise it.

Suggestions

Replace the generic "development patterns" with concrete capabilities, e.g. "Construct service clients, configure credentials, handle streams, paginate results, and run DynamoDB/S3 operations".

Add common service-level trigger terms (S3, DynamoDB, Lambda, STS) so users who name a specific service still match.

DimensionReasoningScore

Specificity

The phrase "AWS SDK for JavaScript v3 development patterns" names the domain but the capability is generic ("development patterns"); the concrete actions (schemas, validation, serialization, code generation) appear only in the when-clause, not as stated capabilities.

2 / 5

Completeness

Both what ("AWS SDK for JavaScript v3 development patterns") and when (explicit "Use when…" clause with concrete triggers) are present, but the "what" is thin and vague relative to the rich when-clause, placing it just below the top anchor.

4 / 5

Trigger Term Quality

Good natural-term coverage including "JavaScript or TypeScript code", "@aws-sdk/* packages", "aws-sdk-js-v3", and task keywords (schemas, runtime validation, serialization, code generation); a few common service-level synonyms (e.g. S3, DynamoDB) are missing.

4 / 5

Distinctiveness Conflict Risk

Scoped tightly to "@aws-sdk/* packages (aws-sdk-js-v3)" / "JS/TS AWS SDK" with distinct, package-anchored triggers and minimal overlap risk with non-AWS skills.
