GitHub Copilot and some other providers have a 64-character limit on
tool_call_id. When switching from providers that generate longer IDs
(such as OpenAI Codex), this caused validation errors.
This fix truncates tool_call_id to 64 characters by preserving the first
32 and last 32 characters to maintain uniqueness while respecting the
provider's limit.
Fixes#1554
Some LLM providers return tool_calls[0].arguments as a list instead of
dict or str. Add handling to extract the first dict element from the list.
Fixes /new command warning: 'unexpected arguments type list'
Instead of always sending interactive cards, detect the optimal
message format based on content:
- text: short plain text (≤200 chars, no markdown)
- post: medium text with links (≤2000 chars)
- interactive: complex content (code, tables, headings, bold, lists)
SIGHUP and SIGPIPE are not available on Windows. Add hasattr() checks
before registering these signal handlers to prevent AttributeError on
Windows systems.
Fixes compatibility issue introduced in PR #1400.
Previously, mp4 video files were sent with msg_type "file", which meant
users had to download them to play. Feishu requires msg_type "media" for
audio and video files to enable inline playback in the chat.
Changes:
- Add _VIDEO_EXTS constant for video file extensions (.mp4, .mov, .avi)
- Use msg_type "media" for both audio (_AUDIO_EXTS) and video (_VIDEO_EXTS)
- Keep msg_type "file" for documents and other file types
The upload_file API already uses file_type="mp4" for video files via the
existing _FILE_TYPE_MAP, so only the send msg_type needed fixing.
Feishu downloads images with incorrect extensions (e.g. .jpg for PNG files).
mimetypes.guess_type() relies on the file extension, causing a MIME mismatch
that Anthropic rejects with 'image was specified using image/jpeg but appears
to be image/png'.
Fix: read the first bytes of the image data and detect the real MIME type via
magic bytes (PNG: 0x89PNG, JPEG: 0xFFD8FF, GIF: GIF87a/GIF89a, WEBP: RIFF+WEBP).
Fall back to mimetypes.guess_type() only when magic bytes are inconclusive.
