+# grammY
+
+## grammY Integration (Telegram Bot API)
+
+## Why grammY
+
+- TS-first Bot API client with built-in long-poll + webhook helpers, middleware, error handling, rate limiter
+- Cleaner media helpers than hand-rolling fetch + FormData; supports all Bot API methods
+- Extensible: proxy support via custom fetch, session middleware (optional), type-safe context
+
+## What We Shipped
+
+- **Single client path:** fetch-based implementation removed; grammY is now the sole Telegram client (send + gateway) with the grammY throttler enabled by default
+- **Gateway:** `monitorTelegramProvider` builds a grammY `Bot`, wires mention/allowlist gating, media download via `getFile`/`download`, and delivers replies with `sendMessage/sendPhoto/sendVideo/sendAudio/sendDocument`. Supports long-poll or webhook via `webhookCallback`
+- **Proxy:** optional `channels.telegram.proxy` uses `undici.ProxyAgent` through grammY's `client.baseFetch`
+- **Webhook support:** `webhook-set.ts` wraps `setWebhook/deleteWebhook`; `webhook.ts` hosts the callback with health + graceful shutdown. Gateway enables webhook mode when `channels.telegram.webhookUrl` + `channels.telegram.webhookSecret` are set (otherwise it long-polls)
+- **Sessions:** direct chats collapse into the agent main session (`agent:<agentId>:<mainKey>`); groups use `agent:<agentId>:telegram:group:<chatId>`; replies route back to the same channel
+- **Config knobs:** `channels.telegram.botToken`, `channels.telegram.dmPolicy`, `channels.telegram.groups` (allowlist + mention defaults), `channels.telegram.allowFrom`, `channels.telegram.groupAllowFrom`, `channels.telegram.groupPolicy`, `channels.telegram.mediaMaxMb`, `channels.telegram.linkPreview`, `channels.telegram.proxy`, `channels.telegram.webhookSecret`, `channels.telegram.webhookUrl`
+- **Draft streaming:** optional `channels.telegram.streamMode` uses `sendMessageDraft` in private topic chats (Bot API 9.3+). This is separate from channel block streaming
+- **Tests:** grammy mocks cover DM + group mention gating and outbound send; more media/webhook fixtures still welcome
+
+## Open Questions
+
+- Optional grammY plugins (throttler) if we hit Bot API 429s
+- Add more structured media tests (stickers, voice notes)
+- Make webhook listen port configurable (currently fixed to 8787 unless wired through the gateway)
