Decision Guardian automatically surfaces Architecture Decision Records (ADRs) directly in Pull Requests when developers modify protected files. How It Works 1) Create decision file with architectural choices 2) Add GitHub Action (10-minute setup) 3) Automatic PR comments with relevant context Example: Developer touches database config → Gets auto-comment: "⚠️ We chose Postgres for ACID compliance (PCI-DSS). Alternatives rejected: MongoDB. [Full context]" Results 1) 80% reduction in "why did we choose X?" questions 2) 40% faster onboarding for new developers 3) 87% of PRs include automated context 4) Zero repeated architecture debates
