aws-patterns
Lambda best practices, S3 event patterns, SQS/SNS fanout, and DynamoDB access patterns for serverless AWS architectures.
npx skills add vibeeval/vibecosystem --skill aws-patterns --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# AWS Patterns Serverless and managed service patterns for AWS production workloads. ## Lambda Best Practices ```typescript // Cold start optimization: keep handler thin, initialize outside handler import { DynamoDBClient } from '@aws-sdk/client-dynamodb' import { DynamoDBDocumentClient, GetCommand } from '@aws-sdk/lib-dynamodb' // Initialized ONCE per container (reused across invocations) const client = DynamoDBDocumentClient.from(new DynamoDBClient({})) export const handler = async (event: APIGatewayProxyEvent) => { try { const userId = event.pathParameters?.id if (!userId) { return { statusCode: 400, body: JSON.stringify({ error: 'Missing user ID' }) } } const result = await client.send(new GetCommand({ TableName: process.env.USERS_TABLE!, Key: { pk: `USER#${userId}`, sk: `PROFILE` } })) if (!result.Item) { return { statusCode: 404, body: JSON.stringify({ error: 'User not found' }) } } return { statusCode: 200, headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(result.Item) } } catch (err) { console.error('Handler error:', err) return { statusCode: 500, body: JSON.stringify({ error: 'Internal server error' }) } } } ``` ## S3 Event Processing ```typescript // S

What does the aws-patterns skill do?
Lambda best practices, S3 event patterns, SQS/SNS fanout, and DynamoDB access patterns for serverless AWS architectures.
How do I install it?
Run `npx skills add vibeeval/vibecosystem --skill aws-patterns --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From vibeeval/vibecosystem, a repository with 521 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
