+## [1.4.0]
+
+### Added
+
+- Add `--allow-dirs` flag to accept specific non-standard directories without
+  warnings ([#39]). Allowed directories are exempt from deep-nesting checks
+  and skipped for orphan detection (with an informational note). Useful for
+  development directories like `evals/` or `testing/` that aren't part of the
+  spec but are needed during skill development.
+
+### Changed
+
+- Refactor `--only` and `--skip` flags from manual comma-separated string
+  parsing to `StringSliceVar`, matching the `--allow-dirs` flag style. Both
+  comma-separated (`--only=structure,links`) and repeated
+  (`--only=structure --only=links`) syntax are now supported. Existing
+  comma-separated usage is unaffected.
+- Restructure `validate structure` and `check` flag documentation in the
+  README from dense prose paragraphs into scannable tables.
