tomevault-io 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
OpenS3Explorercommand - CloudWatch Log Viewer: Interactive log viewer via
OpenCloudWatchLogViewcommand - 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.disabledToolssetting
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
SetAwsReadonlyModeto 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.

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
DescribeStackResourcesto discover all related resources in a stack - Check IAM roles: Use
IAMToolGetRoleandListAttachedRolePoliciesto 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
