create_item should support a description parameter (markdown)

[david206]

Problem

There is no way to set an item's description when creating an item. The only path is a two-step flow:

1. create_item — creates the item
2. all_monday_api with set_item_description_content — sets the description via raw GraphQL

The second step requires knowing that set_item_description_content exists at all, which means dumping and grepping the full GraphQL schema (51KB). In practice, LLM agents fall back to create_update instead — which creates an update (on the second task tab), not a description (on the first task tab).

Root cause

set_item_description_content was added to the Monday API on January 26, 2026 (v2026-04) and is not yet surfaced as a dedicated MCP tool.

Proposed fix

Add an optional description (markdown string) parameter to create_item. Internally, after creating the item, the tool calls set_item_description_content with the provided markdown.

This collapses a two-call, schema-diving workflow into a single obvious operation.

Alternatives considered

• A standalone set_item_description tool — better than the current situation where agents use create_update, but doesn't solve the creation case
• Documenting the mutation in all_monday_api's description — reduces the discoverability gap but doesn't fix the DX
