Heptabase CLI

Prerequisites

• CLI installed from the desktop app. The command is heptabase on macOS/Linux; Windows installs heptabase.cmd for cmd/PowerShell and a heptabase shim for POSIX shells.
• Check version compatibility before use with heptabase --version. If the installed CLI version is outside this skill's compatibility range (0.7.x), you MUST stop and ask the user to update either the Heptabase desktop app or this skill package before continuing.

Command discovery

Run heptabase help to see all available top-level commands. This is always up to date. Each command supports --help for detailed usage:

heptabase help
heptabase note --help
heptabase note create --help

Common recipes

Use these as quick recipes for frequent requests. For less common flags or if a command fails, run heptabase help or <command> --help to discover the correct syntax.

• Recent cards: heptabase card list --sort createdTime --direction descending --limit 20
• Today's journal: heptabase journal read $(date +%Y-%m-%d)
• Search cards by keyword: heptabase card list -q "<keyword>" --limit 20
• Create a note from markdown: heptabase note create --content "# Title\n\nBody" (marks Created by AI by default; add --no-created-by-ai for human-owned content).
• Create today's journal from markdown: heptabase journal create --content "Body" (marks Created by AI by default; add --no-created-by-ai for human-owned content).
• Append markdown to a note: heptabase note append <cardId> --content "More content".
• Edit note content with JSON save: first read references/card-content-schema.md, then use heptabase note read <cardId>, modify the returned ProseMirror JSON, and save with heptabase note save <cardId> --content-md5 <contentMd5> --content-file <path>.
• Work with properties: use heptabase tag cards <tagId> --include-properties to list tagged cards with values, or heptabase card properties <cardIdOrDate> to inspect one card. Before writing, read references/property-values.md, inspect definitions with heptabase tag properties <tagId>, then use heptabase card set-property <cardIdOrDate> --property-id <propertyId> --value "Published" for strings/options or --json-value ... for typed JSON values.
• Read parsed PDF content: first read references/pdf-reading.md, then use heptabase pdf metadata <pdfCardId> to discover totalPages, and read a page range with heptabase pdf read <pdfCardId> --start-page N --end-page N.
• Read transcript content: first read references/transcript-reading.md, then use heptabase audio metadata <audioCardId> or heptabase video metadata <videoCardId> to discover transcriptStatus and durationSeconds, and read overlapping transcript entries in a time range with heptabase audio read <audioCardId> --start-seconds 0 --end-seconds 300 or heptabase video read <videoCardId> --start-seconds 0 --end-seconds 300.
• Read an attached file: first read references/file-reading.md. If needed, find its ID with heptabase file list --card-id <cardId>, then run mktemp -d and heptabase file export <fileId> --output-dir <scratchDir>. Read the returned path with your native file-reading tool.
• Add a local image to a note: first read references/image-import.md, then run heptabase file import <path> and add an image node through note read and note save: set fileId, and set originalWidth and originalHeight to the returned width and height.
• Inspect a whiteboard: heptabase whiteboard read <whiteboardId> --mode structure, then heptabase whiteboard read-layout <whiteboardId>.
• Read chat messages: Copy a chat ID from whiteboard read output, then use heptabase object read chat <chatId> --offset <n> --limit <n> to paginate non-removed messages with their displayed author, timestamp, quoted content, and message content. For a whiteboard chat-messages element, use heptabase object read chatMessagesElement <elementId> --offset <n> --limit <n>.
• Check or view whiteboard layout: run heptabase whiteboard lint <whiteboardId>. For visual review, first read references/whiteboard.md, then use heptabase whiteboard screenshot <whiteboardId> --output <existingDirectory>/whiteboard.png and inspect the returned local path.
• Change whiteboard layout or a mind map: first read references/whiteboard.md; for mind maps, also read references/mind-maps.md. Commands with nested or batch input use --input <path|-> and canonical JSON.

Heptabase URLs (Deep links)

When the user shares a Heptabase URL (aka. deep link), use the CLI to read it — do NOT open it in a browser if the user does not explicitly ask you to (the app requires authentication and browsers used by agents are typically not logged in).

URL patterns and how to handle them:

• Journal card: https://app.heptabase.com/<workspaceId>/card/<YYYY-MM-DD> → heptabase journal read <YYYY-MM-DD>
• Card by UUID: https://app.heptabase.com/<workspaceId>/card/<uuid> → first run heptabase card properties <uuid> to discover the card type, then read its content with the matching command (heptabase note read <uuid>, heptabase pdf metadata <uuid>, etc.).
• Whiteboard: https://app.heptabase.com/<workspaceId>/whiteboard/<uuid> → run heptabase whiteboard read <uuid> --mode structure and heptabase whiteboard read-layout <uuid>. Read references/whiteboard.md before any layout mutation or visual judgment.

The <workspaceId> segment in the URL is not needed by the CLI — extract only the card/whiteboard ID.

Note and journal card content editing

Use create / append with Markdown for ordinary writing. Before calling heptabase note save / heptabase journal save with ProseMirror JSON, you MUST read references/card-content-schema.md. Also read it before generating Markdown that uses Heptabase-specific extensions such as card mentions, whiteboard mentions, dates, videos, math, or toggle/todo lists.

Created by AI marking

note create and journal create mark content as Created by AI by default. Before deciding whether to pass --no-created-by-ai, you MUST read references/created-by-ai.md.

Property editing

Before setting a property value, you MUST read references/property-values.md and inspect the target property with heptabase card properties <cardIdOrDate> and/or heptabase tag properties <tagId>. Property formats vary by type, and relation writes replace the full relation value. For relation properties, use heptabase tag properties <sourceTagId> to get the property definition's relationTargetTagId, then list valid related cards before writing.

File reading

Before reading/listing files or exporting a file, you MUST read references/file-reading.md.

Image import

Before importing an image or adding it to a note, you MUST read references/image-import.md.

PDF reading

Before reading parsed PDF content, you MUST read references/pdf-reading.md.

Transcript reading

Before reading parsed media transcripts, you MUST read references/transcript-reading.md.
