## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `HJARNI_CREATE_CONTAINER` | Create Container | Create a root or nested Hjarni container for organizing notes. |
| `HJARNI_CREATE_NOTE` | Create Note | Create a Markdown note in the inbox or a container. Tags named in tag_names are applied as part of creation. Free accounts are limited to 25 notes, so check account status if quota pressure is possible. |
| `HJARNI_CREATE_NOTES` | Create Notes | Create 1-25 Markdown notes in order and return one result per input. This batch is non-atomic: successful notes remain created if another item fails. |
| `HJARNI_CREATE_TAG` | Create Tag | Create a Hjarni tag for organizing notes. |
| `HJARNI_GET_ACCOUNT_STATUS` | Get Account Status | Return the connected Hjarni identity, token scope, plan, teams, and current resource usage and quotas. Use this before creating many notes or attachments; Free accounts allow 25 notes, 5 attachments, and 20 MB of attachment storage. |
| `HJARNI_GET_NOTE` | Get Note | Get one Hjarni note by ID with its Markdown body, tags, container, attachments, links, and optimistic-lock version. |
| `HJARNI_LIST_CONTAINERS` | List Containers | List Hjarni containers as active roots, archived roots, or all active containers in a flat view. Use next_cursor to page through results. |
| `HJARNI_LIST_NOTES` | List Notes | List and filter personal Hjarni notes, including active, inbox, archived, or favorited notes. Use next_cursor to page through results; use query for simple personal-note filtering. |
| `HJARNI_LIST_TAGS` | List Tags | List all Hjarni tags and their note counts. Use next_cursor to page through results. |
| `HJARNI_LIST_TRASHED_NOTES` | List Trashed Notes | List recoverable trashed Hjarni notes with their deletion and scheduled purge times. Use next_cursor to page through results. |
| `HJARNI_RENAME_TAG` | Rename Tag | Rename an existing Hjarni tag without changing its note associations. |
| `HJARNI_RESTORE_NOTE` | Restore Note | Restore a note from Trash before its scheduled purge and return the active note. |
| `HJARNI_TRASH_NOTE` | Move Note to Trash | Move a note to recoverable Trash. This is not immediate permanent deletion: Hjarni retains the note for about 30 days, and RESTORE_NOTE can recover it before purge. |
| `HJARNI_UPDATE_CONTAINER` | Update Container | Update a Hjarni container's name, description, parent, position, or container-specific AI instructions. |
| `HJARNI_UPDATE_NOTE` | Update Note | Update note metadata, placement, tags, or body. body replaces the entire Markdown body; append_body safely appends text. Provide expected_lock_version from GET_NOTE to prevent overwriting concurrent edits. |
