AWS Cloud Operations Skill
Installation
The skill invokes the AWS CLI v2. Install and configure:
- Linux x86: Download AWS CLI v2, unzip, then
sudo./aws/install - macOS:
curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"then run the installer - Windows: Download MSI from AWS CLI v2 or use
msiexec; or install via package managers
Configure: aws configure (access key, secret, region). Verify: aws --version
Cheat Sheet & Best Practices
Identity & config: aws sts get-caller-identity — who am I; aws configure list-profiles — list profiles.
S3: aws s3 ls; aws s3 cp <local> s3://bucket/; aws s3 sync./dir s3://bucket/; aws s3 rm s3://bucket/key.
Lambda: aws lambda list-functions; aws lambda invoke --function-name X output.json; aws lambda get-function --function-name X.
CloudWatch: aws cloudwatch list-metrics; aws cloudwatch get-metric-statistics; aws cloudwatch describe-alarms; put-metric-alarm for alerts.
EC2: aws ec2 describe-instances; start-instances/stop-instances/terminate-instances with --instance-ids.
Best practices: Use IAM roles over long-lived keys; set AWS_REGION/AWS_PROFILE; use --output json and --query to limit response size; run destructive ops only after describe to confirm resources.
Certifications & Training
Free: AWS Skill Builder — exam prep, Cloud Quest, Cloud Essentials. Cloud Practitioner (CLF-C02): Cloud concepts, security/compliance, technology/services, billing (~6 months exposure). Solutions Architect Associate: Next step; prep on Skill Builder.
Skill data: Map to S3, Lambda, CloudWatch, EC2, IAM; security best practices; no hardcoded credentials.
Hooks & Workflows
Suggested hooks: Pre-deploy: validate credentials (aws sts get-caller-identity). Cost-tracking hook: optional CloudWatch/billing checks. No mandatory hook; use when devops is routed for AWS tasks.
Workflows: Use with devops (contextual: aws_project). Flow: detect AWS project → load aws-cloud-ops → run CLI via skill script. See operations/incident-response if debugging AWS resources.
Overview
Provides 90%+ context savings vs raw AWS MCP server. Multi-service support with progressive disclosure by service category.

Quick Reference
# List EC2 instances
aws ec2 describe-instances --output table
# Tail CloudWatch logs
aws logs tail /aws/lambda/my-function --follow
# List S3 buckets
aws s3 ls
# Invoke Lambda
aws lambda invoke --function-name my-func output.jsonConfiguration
- AWS_PROFILE: Named profile to use
- AWS_REGION: Target region (e.g., us-east-1)
- AWS_DEFAULT_OUTPUT: Output format (json/table/text)
Security
⚠️ Never hardcode credentials ⚠️ Use IAM roles when possible ⚠️ IAM write operations are blocked
Agent Integration
- devops (primary): Cloud operations
- cloud-integrator (primary): Multi-cloud
- incident-responder (secondary): Troubleshooting
Troubleshooting
| Issue | Solution |
|---|---|
| Access denied | Check IAM permissions |
| Region error | Set AWS_REGION |
| Credentials | Run aws configure |
Memory Protocol (MANDATORY)
Before starting: Read .claude/context/memory/learnings.md
After completing:
- New pattern ->
.claude/context/memory/learnings.md - Issue found ->
.claude/context/memory/issues.md - Decision made ->
