-# 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.
