Lists multiple specific concrete actions: detect infrastructure drift, identify unmanaged resources, identify manual changes, and identify configuration drift. These are clear, actionable capabilities.

Clearly answers both 'what' (detect infrastructure drift, identify unmanaged resources, manual changes, configuration drift) and 'when' with an explicit 'Use when:' clause listing five specific trigger scenarios.

Excellent coverage of natural terms users would say: 'infrastructure drift', 'unmanaged cloud resources', 'drift detection', 'Terraform drift', 'compare cloud state to IaC', 'audit infrastructure changes'. These are terms users would naturally use when needing this skill.

Highly distinctive with a clear niche: Terraform drift detection specifically. The combination of 'Terraform state', 'drift detection', 'unmanaged resources', and 'IaC' creates a very specific domain that is unlikely to conflict with other skills.

The skill is reasonably well-structured but includes unnecessary verbosity in several places. The prerequisites section explains basic cloud credential setup that Claude already knows, the report template in Phase 3 is overly detailed, and the error handling section states obvious solutions. The phased structure adds organizational overhead for what could be more concise.

The skill provides fully executable, copy-paste ready commands throughout — from basic snyk CLI invocations to remote state scanning, terraform import blocks, CI/CD YAML, and exclude policy generation. Each phase has concrete commands with real flags and arguments.

The five-phase workflow is clearly sequenced (Setup → Detect → Analyze → Remediate → Prevent) with explicit goals per phase. Phase 3 includes risk categorization and prioritization, Phase 4 offers multiple remediation paths with clear decision criteria (import vs delete vs revert vs adopt), and the CI/CD integration includes a validation gate that fails on drift.

References to SERVICES.md and EXAMPLES.md are well-signaled, but the main file is quite long with content that could be split out — the full error handling section, the detailed remediation examples, and the CI/CD integration could each be separate files. The report template and common scenarios sections add bulk that dilutes the overview nature of the skill.
