5 tools

Can't be undone 2Claude Code: ask
  • nexus_npm_package_ws_has_241560546_weekly_down_close_websocket_sessionSends a WebSocket close frame with the specified status code, waits for the server close handshake, and removes the session from the registry.No findings

    Why it is in this group

    • The name "nexus_npm_package_ws_has_241560546_weekly_down_close_websocket_session" says "close": a word for a change.
    • The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
    Description, as the server wrote it
    Sends a WebSocket close frame with the specified status code, waits for the server close handshake, and removes the session from the registry. Returns a final telemetry snapshot. Use when a session is no longer needed. Do NOT use to temporarily pause a session -- the session_id is permanently deallocated after this call and cannot be reused.
  • nexus_npm_package_ws_has_241560546_weekly_down_send_typed_ws_frameSends a single text or binary frame over an open session and returns the frame's Shannon entropy delta relative to the session baseline.No findings

    Why it is in this group

    • The name "nexus_npm_package_ws_has_241560546_weekly_down_send_typed_ws_frame" says "send": a word for sending, and what is sent cannot be taken back.
    Description, as the server wrote it
    Sends a single text or binary frame over an open session and returns the frame's Shannon entropy delta relative to the session baseline. Use for request-response patterns or publishing commands to a WebSocket server. Do NOT use to send a sequence of frames in bulk -- call this tool once per frame. Fails if session_id does not exist or connection is not in OPEN state.
Changes things 1Claude Code: ask
  • nexus_npm_package_ws_has_241560546_weekly_down_open_websocket_sessionEstablishes a persistent WebSocket connection to a target URL and registers it in the stateful session registry.No findings

    Why it is in this group

    • The name "nexus_npm_package_ws_has_241560546_weekly_down_open_websocket_session" says "open": a word for a change.
    Description, as the server wrote it
    Establishes a persistent WebSocket connection to a target URL and registers it in the stateful session registry. Returns a session_id for all subsequent operations. Use when an agent needs to initiate a long-lived connection before sending or receiving frames. Do NOT use to reconnect an already-open session -- call close_websocket_session first, or use the session_id of an existing session.
Only reads 2Claude Code: allow
  • nexus_npm_package_ws_has_241560546_weekly_down_drain_ws_frame_bufferReturns up to max_frames buffered inbound frames received since the last drain (or session open), each annotated with its Shannon entropy delta and schema validation result.No findings

    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    Returns up to max_frames buffered inbound frames received since the last drain (or session open), each annotated with its Shannon entropy delta and schema validation result. Use to poll for incoming messages without holding a blocking connection. Do NOT use as a real-time streaming mechanism -- it returns only frames already buffered.
  • nexus_npm_package_ws_has_241560546_weekly_down_inspect_ws_session_telemetryReturns real-time telemetry for a session: connection state, frame counts, cumulative and rolling Shannon entropy statistics, schema violation rate, and uptime.No findings

    Why it is in this group

    • The name "nexus_npm_package_ws_has_241560546_weekly_down_inspect_ws_session_telemetry" says "inspect": a word for reading.
    Description, as the server wrote it
    Returns real-time telemetry for a session: connection state, frame counts, cumulative and rolling Shannon entropy statistics, schema violation rate, and uptime. Use to diagnose whether a stream is diverging from its expected schema or to verify a session is still alive before sending. Do NOT use as the primary liveness check in a tight loop.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
