An optional global concurrency cap is available via the NANOBOT_MAX_CONCURRENT_REQUESTS env var (default 3, <=0 for unlimited). Also re-binds tool context before each tool execution round to prevent concurrent sessions from clobbering each other's routing info. Tested in production and manually reviewed.

Root cause: The system prompt stated "Reply directly with text for conversations. Only use the 'message' tool to send to a specific chat channel", which led the LLM to believe text replies were sufficient for all responses, including file delivery. Fix: Add an explicit IMPORTANT instruction in the system prompt telling the LLM it MUST use the 'message' tool with the 'media' parameter to send files, and that read_file only reads content for its own analysis.

When the agent called message(media=[...]), the file was never delivered to the user. Implement the full WeChat CDN upload protocol following the reference @tencent-weixin/openclaw-weixin v1.0.2: 1. Generate a client-side AES-128 key (16 random bytes) 2. Call getuploadurl with file metadata + hex-encoded AES key 3. AES-128-ECB encrypt the file and POST to CDN with filekey param 4. Read x-encrypted-param from CDN response header as download param 5. Send message with the media item (image/video/file) referencing the CDN upload Also adds: - _encrypt_aes_ecb() for AES-128-ECB encryption (reverse of existing _decrypt_aes_ecb) - Media type detection from file extension (image/video/file) - Graceful error handling: failed media sends notify the user via text without blocking subsequent text delivery Co-Authored-By: Claude Opus 4.6 (1M context) --- nanobot/channels/weixin.py | 207 ++++++++++++++++++++++++++++++++++++- 1 file changed, 202 insertions(+), 5 deletions(-) diff --git a/nanobot/channels/weixin.py b/nanobot/channels/weixin.py index edd0091..60e34f6 100644 --- a/nanobot/channels/weixin.py +++ b/nanobot/channels/weixin.py @@ -11,7 +11,9 @@ from __future__ import annotations import asyncio import base64 +import hashlib import json +import mimetypes import os import re import time @@ -64,6 +66,15 @@ RETRY_DELAY_S = 2 # Default long-poll timeout; overridden by server via longpolling_timeout_ms.
