 This principle ensures AI assistant capabilities remain available even when individual providers experience issues, supporting continuous development workflow with triple redundancy.
+
+## Implementation Example: MLflow Session Tracking
+
+The MLflow tracking system demonstrates provider agnosticism by extracting actual commands from transcripts rather than maintaining provider-specific patterns:
+
+**Anti-pattern (N×M complexity):**
+- Different regex patterns for each provider
+- Provider detection logic
+- Maintenance burden grows with each new AI assistant
+
+**Correct pattern (provider-agnostic):**
+- Single parser looks for actual `git`, `gh`, and bash commands
+- No provider detection needed
+- Works automatically with any AI assistant
