Thread gates

Thread gates set who can reply to a post.

The available rules are:

• app.bsky.feed.threadgate#mentionRule: Allow replies from actors mentioned in your post.
• app.bsky.feed.threadgate#followingRule: Allow replies from actors you follow.
• app.bsky.feed.threadgate#listRule: Allow replies from actors on a list.

A thread gate may have up to 5 rules.

Setting a thread gate

Typescript

You set a thread gate by creating a app.bsky.feed.threadgate record with the same rkey as the post you're gating.

const {rkey} = new AtUri(postUri)

await agent.com.atproto.repo.createRecord({
  repo: agent.session.did,
  collection: 'app.bsky.feed.threadgate',
  rkey,
  record: {
    $type: 'app.bsky.feed.threadgate',
    post: postUri,
    allow: [
      // allow mentioned users
      {$type: 'app.bsky.feed.threadgate#mentionRule'},
      // allow followed users
      {$type: 'app.bsky.feed.threadgate#followingRule'},
      // allow list members
      {$type: 'app.bsky.feed.threadgate#listRule', list: listUri},
    ],
    createdAt: new Date().toISOString()
  }
})

If a thread gate record is present but empty, then nobody can reply.

await agent.com.atproto.repo.createRecord({
  repo: agent.session.did,
  collection: 'app.bsky.feed.threadgate',
  rkey,
  record: {
    $type: 'app.bsky.feed.threadgate',
    post: postUri,
    // empty allow-list, nobody can reply
    allow: [],
    createdAt: new Date().toISOString()
  }
})

If a thread gate record is not present, then anybody can reply.

Python

You set a thread gate by creating a app.bsky.feed.threadgate record with the same rkey as the post you're gating.

from atproto import AtUri

rkey = AtUri.from_str(post_uri).rkey

record = models.AppBskyFeedThreadgate.Record(
    post=post_uri,
    allow=[
        # allow mentioned users
        models.AppBskyFeedThreadgate.MentionRule(),
        # allow followed users
        models.AppBskyFeedThreadgate.FollowingRule(),
        # allow list members
        models.AppBskyFeedThreadgate.ListRule(list=listUri),
    ],
    created_at=client.get_current_time_iso(),
)
client.app.bsky.feed.threadgate.create(client.me.did, record, rkey)

If a thread gate record is present but empty, then nobody can reply.

record = models.AppBskyFeedThreadgate.Record(
    post=post_uri,
    allow=[],  # empty allow-list, nobody can reply
    created_at=client.get_current_time_iso(),
)
client.app.bsky.feed.threadgate.create(client.me.did, record, rkey)

If a thread gate record is not present, then anybody can reply.
