Description
From the marketplace listing
Lekh is a collaborative diagramming and whiteboarding app. Connect it to ChatGPT to draw diagrams from a description — flowcharts, sequence diagrams, network and cloud architecture diagrams, mind maps, ER diagrams, org charts and more — using Lekh's catalogue of over 4,600 shapes, including AWS, Azure and Google Cloud icons. ChatGPT can also read, render and explain your existing boards, edit them (including while a colleague has the board open), organise boards into folders, and share them.
Who it is for: anyone with a Lekh account who wants a diagram drawn or changed by asking for it.
Limitations: you need a Lekh account; boards larger than 1 MB or 50 pages cannot be opened by the connector; renders use a standard font rather than the board's own; the connector does not see edits made by others until it reads the board again.

Unrelated request. Expected: Lekh tools are not called; ChatGPT answers without the plugin or says Lekh can't help.
Payment request. Expected: no tool is called. The connector has no purchase capability, and ChatGPT says so without promoting a plan.
Access to someone else's board. Expected: the call fails with Lekh's not-found / no-access error; nothing is deleted; ChatGPT reports it cannot access that board.
