Tessa tools

This page documents the built-in tools Tessa uses autonomously during conversations.

Core tools

These tools are available in every Tessa conversation, on every IAPM surface, regardless of Grid connection.

Edit Make targeted edits to existing files

Diagnostic tools

When Tessa is connected to a Grid, she also has access to diagnostic tools via the Cloud Brain. These cover health checks, root cause analysis, pressure detection, service maps, and more. For the full catalog, see Tessa diagnostics.

Notes

  • Tessa selects tools autonomously based on what you ask; you don't invoke them by name.
  • The Write and Edit tools only run inside Active Workspaces; Reference workspaces are read-only.
  • The Task tool spawns sub-agents that run with restricted, read-only permissions (file reads and search only).
