Azure Architecture Decision Records (ADR) Skill

Create formal Architecture Decision Records that document significant infrastructure decisions with Azure-specific context, WAF pillar analysis, and implementation guidance.

Output Naming

ADRs are saved to agent-output/{project}/ with one of two phase prefixes:

Phase	Prefix	Status default	Trigger
Step 3 (Design)	03-des-adr-	Proposed	Architect agent, design/planning language
Step 7 (As-Built)	07-ab-adr-	Accepted	After deploy, implemented/current-state language

Full filename: {prefix}NNNN-{kebab-title}.md (e.g., 03-des-adr-0001-use-cosmos-db-for-state.md). NNNN is 4-digit sequential per project.

The 07-ab-adr- ADR may differ from 03-des-adr- if implementation required changes — document deviations in the "Implementation Notes" section.

Rules

1. One decision per ADR — keep ADRs focused on a single decision
2. Include alternatives — always document at least 2-3 considered and rejected
3. Map to WAF pillars — show impact on each of the 5 Well-Architected pillars
4. Link to requirements — reference the requirement that drove the decision
5. Keep it concise — ADRs should be readable in 5 minutes
6. Document both consequences — at least 1 positive and 1 negative

Steps

1. Gather context — decision context, alternatives, stakeholders
2. Determine number — check existing ADRs in agent-output/{project}/ for next sequence
3. Determine phase — design (03-des-) or as-built (07-ab-)
4. Generate document — follow references/adr-template.md
5. Include WAF analysis — map decision impact to all 5 pillars
6. Document alternatives — list 2-3 with rejection reasons
7. Self-check — run through references/quality-checklist.md
