In group-chat sessions (including Telegram forum topics), the persistent system-prompt context block told the model: "Do not use the message tool to send to this same group — just reply normally." The intent was to prevent duplicate text messages (the reply pipeline delivers text automatically). However, the model interpreted this as a blanket prohibition, including for file attachments and media. When asked to send a file in a forum topic the agent responded with something like "message tool disabled in this chat". Fix: update the instruction to distinguish plain-text replies (still routed automatically, no message tool needed) from media/file sends (which require the message tool with action=send + media/filePath). The updated wording mirrors the existing system-prompt guidance that already explains the NO_REPLY pattern for when the message tool delivers the reply.

Summary
"Do not use the message tool to send to this same group — just reply normally."— intended to suppress duplicate text echoes, but the model read it as a blanket prohibition on the message tool, including for file and media attachments.tools.allow: ["*"]andactions.sendMessage: true. The exec-tool workaround is the only option today.buildGroupChatContext()(src/auto-reply/reply/groups.ts) to clarify the distinction: plain-text replies go through the normal reply pipeline (no message tool), while file/media sends still need the message tool (action=sendwithmedia/filePath).resolveTelegramAutoThreadId()already injects the correctmessage_thread_idwhen the message tool targets the originating forum topic — no changes needed there.Fixes #31368
