auditing-cloud-with-cis-benchmarks

Audit AWS, Azure, and GCP environments against the CIS Foundations Benchmarks by running automated scans with tools like Prowler and ScoutSuite, interpreting failed controls, and tracking remediation for continuous compliance. Use when conducting a cloud security audit, validating CIS benchmark compliance (CIS v5 AWS, v4 Azure, v4 GCP), or setting up continuous cloud compliance monitoring.

Quality

Content

65%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-structured workflow skill with strong concrete commands, but it loses points for missing validation checkpoints in its destructive remediation steps, some avoidable verbosity, and bundle files that are never linked from the body.

Suggestions

Add explicit validation/verification checkpoints to Step 4 (e.g., re-run the relevant Prowler check or the matching boto3 call after each remediation to confirm the control now passes), since the batch/destructive operations currently lack feedback loops.

Link the existing bundle files from the body (e.g., 'For boto3 check snippets see references/api-reference.md' and 'For a runnable single-account audit see scripts/agent.py') so the inlined commands can be trimmed and the skill uses real progressive disclosure.

Remove or move the ASCII coverage-areas table and the 'Key Concepts' glossary; these largely restate CIS structure Claude already knows and pad the token budget.

DimensionReasoningScore

Conciseness

Mostly high-signal commands and pipelines, but the ASCII coverage-areas table and the 'Key Concepts' glossary explain concepts Claude largely already knows and could be trimmed. Not a 3 because some unnecessary explanation remains; not a 1 because it is not padded with basic filler.

2 / 3

Actionability

Provides fully executable, copy-paste-ready commands throughout (prowler scans, aws iam/s3api/cloudtrail/securityhub calls, jq parsing pipelines), matching the 'fully executable code/commands' anchor.

3 / 3

Workflow Clarity

A clear 5-step sequence exists, but Step 4 performs batch/destructive remediation (deleting root keys, bulk-enforcing encryption) with no validation or verification checkpoint, which caps workflow clarity at 2 per the destructive-operations guideline.

2 / 3

Progressive Disclosure

The body is well-sectioned but never references the provided bundle files (references/api-reference.md and scripts/agent.py), while inlining detail that could live in them. References present but not signaled and content that should be separate is inline.

Description

100%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that names specific tools and concrete actions, includes natural 'Use when' triggers, and is clearly distinguishable from neighboring skills. No fluff or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('running automated scans with tools like Prowler and ScoutSuite, interpreting failed controls, and tracking remediation') plus named tools, matching the 'lists multiple specific concrete actions' anchor.

3 / 3

Completeness

Clearly answers both what (audit AWS/Azure/GCP against CIS Benchmarks, interpret failures, track remediation) and when via an explicit 'Use when...' clause with multiple triggers.

3 / 3

Trigger Term Quality

Natural trigger phrases users would say ('conducting a cloud security audit', 'validating CIS benchmark compliance', 'setting up continuous cloud compliance monitoring') give good coverage of natural terms.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (CIS benchmark cloud compliance auditing) with distinct triggers and named tools, making it unlikely to fire for unrelated skills.
