Discord: ThreadStarterBody re-injected on every turn (echo contamination)

증상

Discord thread starter context (ThreadStarterBody) is re-injected into the agent’s input on every turn of a thread conversation, causing echo contamination. The agent receives [Thread starter - for context] repeatedly, which can leak into outbound messages.

원인

Agent encountered an unexpected state or unhandled error condition outside the standard error handling path.

해결법

Set includeThreadStarter: false per-channel in config:

{
  "channels": {
    "discord": {
      "guilds": {
        "<guild-id>": {
          "channels": {
            "*": {
              "includeThreadStarter": false
            }
          }
        }
      }
    }
  }
}

This disables thread starter context entirely (including the useful first-turn context).
