- test_context_prompt_cache: Update test to reflect merged runtime
context and user message (commit ad99d5a merged them into one)
- Remove test_cron_commands.py: cron add CLI command was removed
in commit c05cb2e (unified scheduling via cron tool)
provider.chat() had no retry logic — a transient 429 rate limit,
502 gateway error, or network timeout would permanently fail the
entire message. For a system running cron jobs and heartbeats 24/7,
even a brief provider blip causes lost tasks.
Adds _chat_with_retry() that:
- Retries up to 3 times with 1s/2s/4s exponential backoff
- Only retries transient errors (429, 5xx, timeout, connection)
- Returns immediately on permanent errors (400, 401, etc.)
- Falls through to the final attempt if all retries exhaust
ReadFileTool had no file size check — reading a multi-GB file would
load everything into memory and crash the process. Now:
- Rejects files over ~512KB at the byte level (fast stat check)
- Truncates at 128K chars with a notice if content is too long
- Guides the agent to use exec with head/tail/grep for large files
This matches the protection already in ExecTool (10KB) and
WebFetchTool (50KB).
datetime.fromisoformat(at) raises ValueError for malformed strings,
which propagated uncaught and crashed the tool execution. Now catches
ValueError and returns a user-friendly error message instead.
When the LLM returns malformed tool arguments (e.g. a list or string
instead of a dict), validate_params would crash with AttributeError
in _validate() when calling val.items(). Now returns a clear
validation error instead of crashing.
When a cron job fires, the agent processes the scheduled message and
has access to the cron tool. If the original message resembles a
scheduling instruction (e.g. "remind me in 10 seconds"), the agent
would call cron.add again, creating an infinite feedback loop.
Add a cron-context flag to CronTool that blocks add operations during
cron job execution. The flag is set before process_direct() and cleared
in a finally block to ensure cleanup even on errors.
Fixes#1441
Some LLM providers (Minimax, Dashscope) strictly reject consecutive
messages with the same role. build_messages() was emitting two separate
user messages back-to-back: the runtime context and the actual user
content.
Merge them into a single user message, handling both plain text and
multimodal (image) content. Update _save_turn() to strip the runtime
context prefix from the merged message when persisting to session
history.

- Add --workspace/-w flag to specify workspace directory
- Add --config/-c flag to specify config file path
- Move cron store to workspace directory for per-instance isolation
- Enable running multiple nanobot instances simultaneously
When allow_from is not configured, block all access by default
instead of allowing everyone. This prevents unauthorized access
when channels are enabled without explicit allow lists.
- Add handler for SIGTERM to prevent "Terminated" message on Linux
- Add handler for SIGHUP for terminal closure handling
- Ignore SIGPIPE to prevent silent process termination
- Change os._exit(0) to sys.exit(0) for proper cleanup

Feishu rejects interactive cards that contain more than one table element
(API error 11310: card table number over limit).
Add FeishuChannel._split_elements_by_table_limit() which partitions the flat
card-elements list into groups of at most one table each. The send() method
now iterates over these groups and sends each as its own card message, so all
tables are delivered to the user instead of the entire message being dropped.
Single-table and table-free messages are unaffected (one card, same as before).
Fixes#1382
Improve cron job execution context to ensure proper message delivery and
session history recording.
Changes:
- Add [绯荤粺瀹氭椂浠诲姟] prefix to cron reminder messages to clearly mark
them as system-driven, not user queries
- Use user role for cron reminder messages (required by some LLM APIs)
- Properly handle MessageTool to avoid duplicate message delivery
- Correctly save turn history with proper skip count
- Ensure Runtime Context is included in the message list
This ensures that:
1. Cron jobs execute with proper context
2. Messages are correctly delivered to users
3. Session history accurately records cron job interactions
4. The LLM understands these are system-driven reminders, not user queries
