Changes things 12Claude Code: ask
  • mg_calculator_cagrOpen the CAGR Calculator React MCP App UI.No findings

    Why it is in this group

    • The description's first verb is "open": a word for a change.
    Description, as the server wrote it
    Open the CAGR Calculator React MCP App UI. ALWAYS ask first — never call this tool silently: "Open the calculator directly, or pre-fill it with your inputs?" IF directly → call this tool now with no params. STOP. Do not ask anything else. IF pre-fill → collect only the input schema fields — do not guess or invent field names.
  • mg_calculator_cagr_syncSync user-entered field values of the open CAGR Calculator back to the session store so the model can read them via the state tool.No findings

    Why it is in this group

    • The name "mg_calculator_cagr_sync" says "sync": a word for a change.
    Description, as the server wrote it
    Sync user-entered field values of the open CAGR Calculator back to the session store so the model can read them via the state tool. Called by the View after any field change; hidden from the model.
  • mg_calculator_cagr_updateUpdate one or more fields in the already-open CAGR Calculator.No findings

    Why it is in this group

    • The name "mg_calculator_cagr_update" says "update": a word for a change.
    Description, as the server wrote it
    Update one or more fields in the already-open CAGR Calculator. ALWAYS call mg_calculator_cagr_state first — the user may have changed values manually in the GUI and you must not overwrite them. Pass the version you received from that call (or from the open tool if updating immediately after opening). Only pass the fields the user explicitly asked to change; omit all others. Send all changes in a single call — multiple sequential calls lose intermediate updates (only the last one applies).
  • mg_calculator_dividendOpen the Dividend Calculator React MCP App UI.No findings

    Why it is in this group

    • The description's first verb is "open": a word for a change.
    Description, as the server wrote it
    Open the Dividend Calculator React MCP App UI. ALWAYS ask first — never call this tool silently: "Open the calculator directly, or pre-fill it with your inputs?" IF directly → call this tool now with no params. STOP. Do not ask anything else. IF pre-fill → ask "By amount invested or by number of shares?", then collect only the input schema fields matching that mode — do not guess or invent field names.
