AWS CloudWatch Skill

Use this skill to fetch CloudWatch metrics for ECS / EC2 / RDS and return text summaries.

Entry

Preferred entry script:

node {baseDir}/src/skill.mjs --service ecs --metric cpu --resource <cluster-name> --hours 1

Environment

Required (AK/SK):

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY

Optional:

• AWS_REGION (default: us-west-2)

Usage (internal)

Run the CLI script in {baseDir}:

node {baseDir}/src/cli.js --service ecs --metric CPUUtilization --resource <cluster-name-or-arn> --hours 1
node {baseDir}/src/cli.js --service ecs --metric cpu --resource <cluster-name>

You can define metric aliases in {baseDir}/config.json (see config.example.json).

Supported services

• ecs (cluster-level metrics)
• ec2
• rds

Defaults

• Region: us-west-2
• Period: 300 seconds (5 minutes)
• Time window: 1 hour

Notes

• ECS metrics are cluster-level unless Container Insights is enabled.
• If the metric is unavailable, return a clear message.
• Text-only output (no chart rendering).
• Uses SigV4 signing via native crypto (no AWS SDK, no external packages).
