The skill is reasonably efficient with executable DQL examples and structured sections, but includes some redundancy — the 'When to Load References' section is very verbose, listing 12 reference files with bullet-pointed trigger conditions that could be condensed into a table. The entity type listings and common fields sections are useful reference material but add bulk. Some sections like 'Best Practices' include guidance Claude would likely infer (e.g., 'filter early', 'limit results for exploration').

The skill provides fully executable DQL queries for every workflow — resource discovery, VPC analysis, database monitoring, load balancer topology mapping, cost optimization, and security auditing. Each query is copy-paste ready with realistic field names and filter conditions. The config parsing pattern (`parse aws.object, "JSON:awsjson"`) is consistently demonstrated with concrete field paths.

The workflows are clearly sequenced and cover diverse use cases, but they lack validation checkpoints. For potentially impactful operations like security audits or cost optimization (identifying resources for deletion), there are no verification steps — e.g., confirming an EBS volume is truly unattached before recommending deletion, or validating that a 'publicly accessible' database finding is accurate. The workflows are more query catalogs than guided processes with feedback loops.

Excellent progressive disclosure structure. The main SKILL.md provides a comprehensive overview with working examples for the most common use cases, then clearly signals 12 reference files with specific trigger conditions for when to load each one. References are one level deep, well-organized by domain, and the 'When to Load References' section provides clear decision criteria. The reference links are consistently formatted and appear throughout the relevant workflow sections.

Lists multiple specific concrete actions and resources: EC2, RDS, Lambda, ECS/EKS, VPC networking, load balancers, S3, DynamoDB, SQS/SNS, cost optimization, security compliance, capacity planning, and resource inventory.

Clearly answers both 'what' (AWS cloud resource monitoring across many services) and 'when' (explicit 'Use when' clause plus a detailed 'Trigger' list and 'Do NOT use' exclusions that further clarify scope).

Excellent coverage of natural trigger terms users would actually say, including 'show EC2 instances', 'find RDS databases', 'VPC resources', 'AWS cost optimization', 'unattached EBS volumes', 'publicly accessible databases', and many more specific phrases.

Highly distinctive with explicit boundary-setting via 'Do NOT use' clauses that redirect to specific alternative skills (dt-obs-hosts, dt-obs-tracing, dt-obs-logs), making it very unlikely to conflict with neighboring skills.
