  fileData: [...],       // Uint8Array as number array
  fileName: "spec.pdf",

Field	Required	Description
`taskId`	Yes	Target task ID
`fileData`	Yes	File contents as byte array
`fileName`	Yes	Original file name
`mimeType`	Yes	MIME type (e.g. `application/pdf`, `image/png`)

Upload Attachments (HTTP)

POST /api/tasks/:taskId/attachments
Content-Type: multipart/form-data

Upload one or more files using standard multipart form data. Files should be sent under the files field name.

Delete Attachment

invoke('delete_attachment', { id: 1 })

Permanently removes an attachment and its stored file data.

Attachments are stored in the local SQLite database. They are included in the task detail view and can be referenced by Claude agents during task execution.
