Admitted input schema
{
"type": "object",
"properties": {
"all_video_over_10s": {
"type": "boolean",
"description": "OPTIONAL, defaults to false. Whether EVERY attachment is video running longer than ten seconds. One photo or one short clip makes this false."
},
"brief": {
"type": "boolean",
"description": "OPTIONAL, defaults to false. True returns the classification only and drops the prose, which is 78% of the generation. Answers in seconds instead of tens of seconds, same model and same price. Use it if your client has a short timeout."
},
"followers_under_1000": {
"type": "boolean",
"description": "OPTIONAL, defaults to false. Whether the author is under the small-account cap that the one per-batch lift applies to."
},
"post_kind": {
"type": "string",
"minLength": 0,
"maxLength": 4096,
"enum": [
"original",
"reply",
"quote",
"repost"
],
"description": "OPTIONAL, defaults to original. A reply's parent is not in the text, so no tool can read this off the draft. Declare it only if it is not an original."
},
"reader_follows_back": {
"type": "boolean",
"description": "OPTIONAL, defaults to false. Whether the reader follows the author back. Decides in-network versus out-of-network, which changes the reply chain."
},
"text": {
"type": "string",
"minLength": 0,
"maxLength": 4096,
"description": "The draft post. Never rewritten, never stored."
}
