Document limits
The New document dialog treats
.html and .htm as HTML. It treats every
other suffix as Markdown, so use .md or .markdown for Markdown files.
Artifact types and limits
Document bytes do not count toward artifact quota. Artifact history does.
Deleting the current artifact path does not remove its retained versions from
quota accounting. Deleting the workspace removes those versions from quota
accounting, but stored bytes may remain until cleanup.
MCP limits
Use raw HTTP for an artifact larger than the MCP inline limit. Binary MCP reads
return URLs instead of putting the bytes in the tool result.
