 This requires `TELEGRAM_BOT_TOKEN`, `TELEGRAM_CHAT_ID`, and a configured LLM in `.env`. The bot ignores every other chat ID and polls every 5 seconds by default. For group chats, BotFather privacy settings may prevent the bot from receiving normal text; private chat is recommended. Local reasoning models can take several minutes, so the bot refreshes Telegram's typing indicator while waiting.
 
+#### Intelligence Terminal Tool Agent
+
+When `TELEGRAM_AGENT_ENABLED=true`, the chat can perform up to `TELEGRAM_AGENT_MAX_STEPS` structured tool calls before answering. The allowlist includes system status, latest brief, sweep delta, markets, source health, evidence search, memory, predictions, scenarios, and generated ideas. The agent has no generic shell, filesystem, network, environment, or secret-access tool.
+
+Read-only tools run automatically. `trigger_sweep`, `mute_alerts`, and `unmute_alerts` return an expiring confirmation request with Telegram **Confirm** and **Cancel** buttons. Confirmation is bound to the configured chat and cannot be reused. `/trace` exposes only tool names, duration, status, and a short operational rationale; private chain-of-thought is neither requested nor stored.
+
+With `TELEGRAM_AGENT_PROACTIVE_ENABLED=true`, material sweep changes trigger a separate bounded analysis. The agent can cross-check evidence, source health, scenarios, memory, and predictions before deciding whether to notify. A cooldown limits repeat notifications, and the deterministic alert evaluator remains the fallback when the agent fails or declines a notification that still meets fixed alert rules.
