+### Obsidian Integration
+
+When `stamp` runs inside an Obsidian vault it mirrors your existing date formats.
+
+- **Vault detection**: the CLI walks up from the current working directory until it finds a `.obsidian/` folder.
+- **Daily Notes**: if the core plugin is enabled in `.obsidian/core-plugins.json`, `stamp` reads `daily-notes.json` (or `dailyNotes.format` within `app.json`) and translates the Moment-style string to Go's layout before emitting daily filenames.
+- **Unique Note Creator**: when the community plugin is enabled (or its folder exists) the tool inspects `.obsidian/plugins/unique-note-creator/data.json` for filename patterns and uses them for the default command.
+- **Graceful fallback**: missing files or unsupported tokens leave `stamp` on its built-in formats, and any read/parse issues are emitted as warnings on stderr without interrupting execution.
