Lists multiple specific concrete capabilities: regions, tags, naming (CAF), AVM-first policy, security baseline, unique suffix patterns. These are distinct, actionable areas rather than vague abstractions.

Clearly answers both 'what' (Azure infrastructure defaults covering regions, tags, naming, AVM policy, security baseline) and 'when' (explicit WHEN clause with trigger terms, USE FOR clause, and even a DO NOT USE FOR clause to reduce false positives).

Includes highly natural trigger terms users would say: 'Azure naming convention', 'CAF naming', 'resource tags', 'AVM module', 'security baseline', 'region default'. These cover common variations of how users would phrase Azure infrastructure requests.

Highly distinctive with explicit boundary-setting via the DO NOT USE FOR clause, which differentiates it from azure-artifacts and pricing guidance. The specific Azure infrastructure niche with CAF/AVM terminology makes conflicts unlikely.

The skill is mostly efficient with good use of tables and compact summaries, but some sections (VNet Planning Baseline, Cost Monitoring Baseline) are dense prose blocks that could be tightened. The repeated restatement of rules already covered in Quick Reference (e.g., AVM-first appears in Quick Reference, AVM section, Rules, and Steps) adds redundancy. Some explanatory context (e.g., 'IaC-flavoured mirror of the canonical Azure defaults') is unnecessary.

The skill provides concrete naming patterns, tag requirements, and specific Bicep code for uniqueSuffix, plus specific validation commands. However, most guidance is declarative tables and rules rather than executable code blocks — there are no complete Bicep/Terraform module usage examples, and the AVM section tells you to check availability without showing how. The single code snippet (uniqueString) is good but insufficient for a skill covering this much ground.

The Steps section provides a clear 8-step sequence with explicit validation at step 8 (lint/validate commands), cross-check governance at step 2, and conditional gates (VNet planning at step 6). The workflow includes feedback loops via governance overrides and references to specific validation tooling. The output checklist provides a final verification gate before saving.

Excellent progressive disclosure with a clear Quick Reference section loaded first, then a well-organized Reference Index table with specific 'When to Load' triggers for each of 19 reference files. References are one level deep, clearly signaled with relative paths, and the skill explicitly instructs 'Load these on demand — do NOT read all at once.'
