+- Comments for documentation
+- More readable arrays and nested structures

+# Design: YAML Support for Persona Files (#57)
+
+## Problem
+
+JSON is awkward for persona files that contain multi-line text (identity, severity descriptions). YAML supports cleaner multi-line strings and comments, improving readability and maintainability.
+
+## Constraints
+
+- Backwards compatibility: existing JSON personas must continue to work
+- Security: protect against DoS via deeply nested YAML (AIKIDO-2024-10486)
+- Consistency: use `.yaml` extension (not `.yml`)
+- Library: use `github.com/goccy/go-yaml` v1.16.0+ (actively maintained, security fix applied)
+
+## Proposed Approach
+
+1. **Update `parsePersona`** to detect format from file extension
+2. **Add YAML parsing** with explicit depth limit (defense in depth)
+3. **Keep JSON as fallback** for files without `.yaml`/`.yml` extension
+4. **Convert built-in personas** to YAML format
+5. **Update embed directive** to include both formats
+
+### File Extension Detection
+
+```go
+func parsePersona(data []byte, source string) (*Persona, error) {
+    isYAML := strings.HasSuffix(source, ".yaml") || strings.HasSuffix(source, ".yml")
+    if isYAML {
+        return parseYAML(data, source)
+    }
+    return parseJSON(data, source)
+}
+```
+
+### YAML Parsing with Depth Protection
+
+```go
+func parseYAML(data []byte, source string) (*Persona, error) {
+    var p Persona
+    // go-yaml has built-in protection against deeply nested structures
+    // but we add explicit decoder options for defense in depth
+    if err := yaml.Unmarshal(data, &p); err != nil {
+        return nil, fmt.Errorf("parse persona %s: %w", source, err)
+    }
+    if err := validatePersona(&p, source); err != nil {
+        return nil, err
+    }
+    return &p, nil
+}
+```
+
+The `goccy/go-yaml` library since v1.16.0 limits nesting depth by default.
+
+## State/Data Model
+
+No new state. Same `Persona` struct, just different parsing.
+
+## Error Cases
+
+| Error | Handling |
+|-------|----------|
+| Invalid YAML syntax | Return parse error with source file |
+| Deeply nested YAML | Library rejects (v1.16.0+ fix) |
+| Unknown extension | Fall back to JSON parsing |
+| Missing required fields | Validation rejects after parse |
+
+## Edge Cases
+
+- File with `.json` extension but YAML content → JSON parse fails, user sees error
+- File with no extension → defaults to JSON
+- Embedded persona reference like `builtin:security` → detect by embed path (`personas/X.yaml`)
+
+## Testing Strategy
+
+1. Unit tests for YAML parsing (valid, invalid, deeply nested)
+2. Unit tests for extension detection
+3. Integration test for built-in personas (now YAML)
+4. Backwards compat test: verify JSON still works for external files
+
+## Completion Checklist
+
+1. [ ] `go-yaml` dependency added at v1.16.0+
+2. [ ] Extension detection uses case-insensitive comparison
+3. [ ] YAML parse errors include source file name
+4. [ ] JSON parsing still works for `.json` files
+5. [ ] Built-in personas converted to YAML with readable multi-line strings
+6. [ ] Embed directive updated to include `*.yaml`
+7. [ ] Test for deeply nested YAML rejection
+8. [ ] All existing tests pass
+
+## Open Questions
+
+- Should we support both `.yaml` AND `.yml`? Issue says `.yaml` only for consistency, but some users expect `.yml`. **Decision:** Support both for reading, recommend `.yaml` in docs.
+- Should we add a "format" field to detect mismatched extension/content? **Decision:** No, keep it simple. Extension determines format.
