The role

What QUILL does

QUILL is the dedicated agent behind VZU Sheets. It runs every time the operator briefs the vzu sheets capability. It owns the goal, the toolset, the memory, the audit trail.

The goal

What QUILL is trying to achieve

"Read, write, audit, reconcile XLSX files using the NetWit Agentic OS MCP server for spreadsheets. Preserve formulas, named ranges, data validation, conditional formatting."

The capability

The toolset

4 MCP actions QUILL can call.

Every action is exposed as an MCP server (Model Context Protocol). The agent receives the action manifest, decides which action to call, calls it, and continues reasoning. The audit trail records every call.

  • mcp.xlsx.read

    Read XLSX preserving formulas + formatting

  • mcp.xlsx.write

    Write XLSX preserving structure

  • mcp.xlsx.reconcile

    Reconcile two XLSX files

  • mcp.xlsx.audit

    Audit XLSX for errors

The memory schema

What QUILL remembers between calls.

  • → The XLSX schema
  • → The reconciliation rules
  • → The audit results
