AWS Batch Skill

Analyze AWS Batch compute environments and jobs with parallel execution and anti-hallucination guardrails.

Relationship to other AWS skills:

• aws-batch/ → Batch-specific analysis (compute environments, job queues, jobs)
• aws/ → "How to execute" (parallel patterns, throttling, output format)

CRITICAL: Parallel Execution Requirement

ALL independent operations MUST run in parallel using background jobs (&) and wait.

#!/bin/bash
export AWS_PAGER=""

for ce in $compute_envs; do
  describe_compute_env "$ce" &
done
wait

Helper Functions

# List compute environments

  aws batch describe-compute-environments \
    --output text \
    --query 'computeEnvironments[].[computeEnvironmentName,state,status,type,computeResources.type,computeResources.minvCpus,computeResources.maxvCpus,computeResources.desiredvCpus]'
}

# List job queues
list_job_queues() {
  aws batch describe-job-queues \
    --output text \
    --query 'jobQueues[].[jobQueueName,state,status,priority,computeEnvironmentOrder[].computeEnvironment]'
}

# List jobs by status
list_jobs() {
  local queue=$1 status=$2
  aws batch list-jobs --job-queue "$queue" --job-status "$status" \
    --output text \
    --query 'jobSummaryList[].[jobId,jobName,status,createdAt,startedAt,stoppedAt,statusReason]' | head -20
}

# Describe jobs (batch)
describe_jobs() {
  local job_ids="$@"
  aws batch describe-jobs --jobs $job_ids \
    --output text \
