Problem

Currently, the requireMention setting in Slack channel configuration is binary: either all messages require a mention, or none do. This doesn't allow for nuanced behavior in threaded conversations.

Desired Behavior

In threaded channels (like #parallax-dev), it would be useful to:

• Main channel: Require @mention to respond (avoid noise)
• Inside threads: No @mention required (active participation in ongoing discussion)

Use Case

In project-specific channels, the bot should:

1. Stay quiet in the main channel unless explicitly mentioned
2. Actively participate in threads once engaged

Proposed Config

{
  "channels": {
    "slack": {
      "channels": {
        "C0AB2QU6AAC": {
          "allow": true,
          "requireMention": true,
          "requireMentionInThreads": false
        }
      }
    }
  }
}

Workaround

Currently handling this in AGENTS.md by checking for thread_label in metadata and adjusting response behavior manually.

Context

• Channel: Slack
• Surface: group/channel
• Metadata includes thread_label when in a thread
