Awsflow General

Awsflow is a VS Code extension that provides AI-assisted AWS management capabilities. It allows users to interact with AWS services using natural language prompts directly within VS Code.

When to Use This Skill

Use this skill when the user:

•Asks how to connect to AWS or configure credentials
•Wants to switch AWS profiles, regions, or endpoints
•Needs to test AWS connectivity
•Asks about awsflow extension capabilities or features
•Wants to perform local file operations (read, write, zip)
•Needs to understand cross-service relationships (e.g., which services produce CloudWatch logs)
•Asks about safety, permissions, or readonly mode
•Wants to manage session settings

Extension Capabilities

Natural Language AWS Management

•Ask questions about your AWS resources in plain English
•Execute AWS API calls through chat prompts
•Automatic pagination handling with "Load More" in chat

UI Features

•S3 Explorer: Interactive bucket browser via OpenS3Explorer command
•CloudWatch Log Viewer: Interactive log viewer via OpenCloudWatchLogView command
•Command History: Panel showing all API calls with responses
•Service Access View: Enable/disable individual tools per workspace
•Status Bar: Quick selectors for AWS profile and region

MCP Support

•Built-in for VS Code / GitHub Copilot (no setup needed)
•Stdio MCP bridge for Google Antigravity, Windsurf, Cursor, and other editors
•Up to 3 concurrent MCP sessions
•Tool availability controlled via awsflow.mcp.disabledTools setting

Safety Model

•Read-only operations (list, describe, get): Execute automatically without confirmation
•Mutating operations (put, post, upload, delete, create, update, invoke, start, execute): Require user confirmation before execution
•Readonly mode: Available via SetAwsReadonlyMode to block all write operations

AWS Connectivity & Session Management

How Credentials Work

Awsflow uses the standard AWS SDK credential provider chain:

•Environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
•AWS SSO (Single Sign-On) via aws sso login
•Shared credentials file (~/.aws/credentials)
•Shared config file (~/.aws/config)

Important: No credentials are ever sent to AI services. All API calls execute locally.

Quick Setup Steps

•Install the awsflow extension in VS Code
•Use TestAwsConnectionTool to verify connectivity
•Use SessionTool with ListProfiles to see available profiles
•Use SessionTool with SetSession to configure profile and region
•Start using any AWS service tool via chat

Cross-Service Discovery Guide

Many AWS services produce logs, metrics, and resources that can be found through other services. Use this guide to navigate between related services.

CloudWatch Log Group Naming Conventions

AWS Service	Log Group Pattern	How to Find
Lambda	`/aws/lambda/{functionName}`	Use `CloudWatchLogTool` with `DescribeLogGroups` prefix `/aws/lambda/`
API Gateway	`API-Gateway-Execution-Logs_{restApiId}/{stageName}`	Use `CloudWatchLogTool` with prefix `API-Gateway-Execution-Logs_`
Glue	`/aws-glue/jobs/output`	Use `CloudWatchLogTool` with prefix `/aws-glue/`
RDS	`/aws/rds/instance/{instanceId}/{logType}`	Use `CloudWatchLogTool` with prefix `/aws/rds/`
ECS	`/ecs/{serviceName}` or custom	Use `CloudWatchLogTool` with prefix `/ecs/`
Step Functions	`/aws/vendedlogs/states/{stateMachineName}`	Use `CloudWatchLogTool` with prefix `/aws/vendedlogs/states/`
CloudTrail	`aws-cloudtrail-logs-{accountId}`	Use `CloudWatchLogTool` with prefix `aws-cloudtrail-logs-`
VPC Flow Logs	Custom log group (check EC2 flow log config)	Use `EC2Tool` `DescribeFlowLogs` to find log group

Service Relationship Map

From Service	Related Service	How to Navigate
Lambda Function	CloudWatch Logs	Log group: `/aws/lambda/{functionName}`
Lambda Function	SQS/SNS/DynamoDB/Kinesis	Use `LambdaTool` `ListEventSourceMappings` to find event sources
Lambda Function	IAM Role	Check `GetFunctionConfiguration` for `Role` field
EC2 Instance	VPC, Subnet, Security Groups	Instance metadata contains `vpcId`, `subnetId`, `securityGroups`
EC2 Instance	CloudWatch	VPC Flow Logs → CloudWatch Log Group
API Gateway	Lambda	Integration targets in `GetIntegration` response
API Gateway	CloudWatch	Execution logs: `API-Gateway-Execution-Logs_{id}/{stage}`
Glue Job	CloudWatch Logs	Output logs: `/aws-glue/jobs/output`
Glue Job	S3	Job scripts and data stored in S3
Step Functions	Lambda/ECS/Glue/SNS/SQS/DynamoDB	Task states reference other services by ARN
CloudFormation	All Services	`DescribeStackResources` lists all managed resources
CloudFormation	Templates	`GetTemplate` returns the infrastructure definition
IAM Role	All Services	Roles are used by Lambda, EC2, Glue, Step Functions, etc.
RDS	RDS Data API	Use `RDSDataTool` for SQL execution on Aurora Serverless
RDS	CloudWatch	RDS logs → CloudWatch, Enhanced Monitoring → CloudWatch
S3	SNS/SQS/Lambda	Event notifications trigger other services
SNS	SQS/Lambda/HTTP	Subscriptions deliver to other service endpoints
SQS	Lambda	SQS queues as Lambda event sources
SQS	Dead Letter Queue	`ListDeadLetterSourceQueues` finds failed message sources
EMR	S3/EC2/CloudWatch	Clusters use S3 for data, EC2 for compute, CW for logs

Tips for Finding Related Resources

•Start with CloudFormation: If infrastructure is managed by CloudFormation, use DescribeStackResources to discover all related resources in a stack
•Check IAM roles: Use IAMTool GetRole and ListAttachedRolePolicies to understand what services a role can access
•Use tags: Many services support tags — use tag-based queries to find related resources across services
•Follow ARNs: When a service response includes ARNs to other resources, use the appropriate tool to inspect those resources
