The existing `validate_params()` and `cast_params()` methods expected only simple strings as `type`, causing `TypeError: unhashable type: 'list'` on every MCP tool call with nullable parameters. Add `_resolve_type()` helper that extracts the first non-null type from union types, and use it in `_cast_value()` and `_validate()`. Also handle `None` values correctly when the schema declares a nullable type.

mask secrets, remove emoji, reduce repetition - Mask sensitive fields (api_key/token/secret/password) in all display surfaces, showing only the last 4 characters - Replace all emoji with pure ASCII labels for consistent cross-platform terminal rendering - Extract _print_summary_panel helper, eliminating 5x duplicate table construction in _show_summary - Replace 3 one-line wrapper functions with declarative _SETTINGS_SECTIONS dispatch tables and _MENU_DISPATCH in run_onboard - Extract _handle_model_field / _handle_context_window_field into a _FIELD_HANDLERS registry, shrinking _configure_pydantic_model - Return FieldTypeInfo NamedTuple from _get_field_type_info for clarity - Replace global mutable _PROVIDER_INFO / _CHANNEL_INFO with @lru_cache - Use vars() instead of dir() in _get_channel_info for reliable config class discovery - Defer litellm import in model_info.py so non-wizard CLI paths stay fast -

Refactor shared kwargs building in each provider. Channel layer: BaseChannel gains send_delta (no-op) and supports_streaming (checks config + method override). ChannelManager routes _stream_delta / _stream_end to send_delta, skips _streamed final messages. AgentLoop._dispatch builds bus-backed on_stream/on_stream_end callbacks when _wants_stream metadata is set. Non-streaming path unchanged. CLI: clean up spinner ANSI workarounds, simplify commands.py flow.

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.

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.
