Tools (13)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • annotatePin a comment on the board

    Pin an interviewer comment bubble on the board, pointing at a component (by id or label) or at a position. Great for "what if this fails?" style probes.

  • clear_annotationsRemove interviewer commentscan change or delete data

    Remove your pinned comments (all, or specific ids).

  • draw_on_boardDraw on the board

    Description is built at runtime.

  • end_interviewEnd the interview with feedback

    Close the session and show a feedback card on the board. Scores are 1-5.

  • get_boardRead the boardread-only

    Structured description of the board: components (type, label, id, position, zone), connections (from -> to, label, dashed=async), zones, notes and text, freehand strokes, plus what changed since you last looked.

  • get_board_imageLook at the boardread-only

    A PNG picture of the whole board as the candidate sees it (handwriting, sketches, layout). Use when get_board mentions freehand strokes or you need visual context.

  • get_transcriptConversation transcriptread-only

    Full chat/voice transcript of the current session.

  • highlightPoint at components

    Make components glow on the candidate’s board (e.g. while asking about them). Optionally scroll/zoom their view to them.

  • open_boardOpen the board

    Open the sketch board in the user’s browser and return its URL.

  • saySpeak to the candidate

    Send a message to the candidate. It appears in the board chat and is read aloud. Keep it short and conversational (no markdown).

  • set_phaseMove to an interview phase

    Description is built at runtime.

  • start_interviewStart a system design interviewcan change or delete data

    Start a new interview session on the board: sets the problem statement, timer and phase, opens the board, and posts your opening message (spoken aloud to the candidate).

  • wait_for_candidateListen to the candidateread-only

    Block until the candidate says something (typed or by voice), the board changes and then settles, or the timeout passes. Returns what they said, what changed on the board, and interview timing. Call this in a loop between your replies.
