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

100%

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

An excellent reference skill body: token-efficient, packed with executable examples, clearly organized, and properly offloading advanced material to a well-structured references directory. It is a model of progressive disclosure with no significant weaknesses.

DimensionReasoningScore

Conciseness

The body is lean throughout: tight one-line lead-ins followed by executable code, assuming Claude already knows JS/TS, with no padding or restating of basic concepts; every section earns its tokens.

3 / 3

Actionability

Dense with fully executable, copy-paste-ready snippets (correct imports, real command objects, concrete config) across clients, credentials, streams, paginators, DynamoDB, S3, errors, and middleware.

3 / 3

Workflow Clarity

Each pattern is unambiguous and correctly sequenced where it matters (e.g. Lambda init outside the handler with lazy in-handler setup, stream read/discard guidance); this is a patterns reference rather than a fragile batch operation, so no validation checkpoint is required to score the top anchor.

3 / 3

Progressive Disclosure

SKILL.md is a concise overview that pushes advanced detail into 11 well-signaled, one-level-deep reference files (e.g. 'see `references/clients.md`'), all of which exist in the bundle; the single clients.md -> schemas.md cross-link is harmless since schemas.md is also directly reachable from the body.

Description

90%

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 strong, third-person description with an explicit 'Use when' trigger and a distinct AWS SDK v3 niche. The only weakness is that the capability statement leans on the abstract phrase 'development patterns' rather than enumerating concrete service actions.

Suggestions

Replace or augment 'development patterns' with concrete verbs, e.g. 'Create S3 presigned URLs, query DynamoDB with the DocumentClient, configure credentials and retry strategies'.

Consider trimming the niche tail ('schemas, runtime validation, serialization, or code generation') if those are secondary, to keep the lead capability statement crisp.

DimensionReasoningScore

Specificity

Names the domain and package ("AWS SDK for JavaScript v3", "@aws-sdk/* packages") and lists some actions ("schemas, runtime validation, serialization, or code generation"), but the core framing "development patterns" is abstract and it does not enumerate concrete service-level actions like the top anchor requires.

2 / 3

Completeness

Clearly answers both what ("AWS SDK for JavaScript v3 development patterns") and when via an explicit "Use when writing... or when asked about..." trigger clause.

3 / 3

Trigger Term Quality

Includes natural terms a user would say ("JavaScript or TypeScript code that uses AWS services", "@aws-sdk/* packages", "aws-sdk-js-v3") with good coverage of the JS/TS AWS SDK niche.

3 / 3

Distinctiveness Conflict Risk

A clear niche scoped to the v3 JS/TS AWS SDK with package-specific triggers, making it unlikely to fire for unrelated skills.
