With resuming enabled, a single card lives across multiple tool-call rounds and can exceed this limit, causing the final response to be silently lost. Remove the _resuming logic from send_delta so each tool-call round gets its own short-lived streaming card (well under 10 min). Add a fallback that sends a regular interactive card when the final streaming update fails. --- docs/CHANNEL_PLUGIN_GUIDE.md | 1 - nanobot/channels/feishu.py | 112 +++++++----------- tests/channels/test_feishu_streaming.py | 65 ++-------- .../test_feishu_tool_hint_code_block.py | 87 +++++++------- 4 files changed, 93 insertions(+), 172 deletions(-) diff --git a/docs/CHANNEL_PLUGIN_GUIDE.md b/docs/CHANNEL_PLUGIN_GUIDE.md index 86e06bf6..65ff9eec 100644 --- a/docs/CHANNEL_PLUGIN_GUIDE.md +++ b/docs/CHANNEL_PLUGIN_GUIDE.md @@ -290,7 +290,6 @@ async def send_delta(self, chat_id: str, delta: str, metadata: dict[str, Any] | |------|---------| | `_stream_delta: True` | A content chunk (delta contains the new text) | | `_stream_end: True` | Streaming finished (delta is empty) | -| `_resuming: True` | More streaming rounds coming (e.g. tool call then another response) | ### Example: Webhook with Streaming diff --git a/nanobot/channels/feishu.py b/nanobot/channels/feishu.py index 5afeca35..1442c363 100644 --- a/nanobot/channels/feishu.py +++ b/nanobot/channels/feishu.py @@ -1290,7 +1290,6 @@ class FeishuChannel(BaseChannel): Supported metadata keys: _stream_end: Finalize the streaming card. -

Document text extraction (PDF, DOCX, XLSX, PPTX) is performed by the new _extract_documents() helper in server.py, called before process_direct(). This keeps the core context builder free of format-specific dependencies and makes the API boundary the single place where uploaded files are pre-processed.

Documents attached to queued messages were silently dropped because _build_user_content only handles images. Fix: call extract_documents before _build_user_content in _drain_pending. Bug 2: extract_documents read the entire file into memory (up to 50 MB) just to check 16 bytes of magic header for MIME detection. Fix: read only the first 16 bytes via open()+read(16) instead of Path.read_bytes(). Added regression tests for both bugs.

The number lived in three places before (code threshold, prompt instruction, docstring); now there is one. - Add `DreamConfig.annotate_line_ages` (default True = current behavior) and propagate it through `Dream.__init__` and the gateway wiring in cli/commands.py. Gives users a knob to disable the feature without a code patch if an LLM reacts poorly to the `← Nd` suffix. - Harden `_annotate_with_ages` against dirty working trees: when HEAD blob line count disagrees with the working-tree content length, skip annotation entirely instead of assigning ages to the wrong lines. The previous `i >= len(ages)` guard only handled one direction of the mismatch. - Inline-comment the `max_iterations` 10→15 bump with a pointer to exp002 so future blame has context. - Add 4 regression tests: end-to-end `← 30d` reaches prompt, 14/15 threshold boundary, `annotate_line_ages=False` bypasses git entirely (verified via `assert_not_called`), length-mismatch defense, and template-var rendering.

Self-hosted OpenAI-compatible Whisper endpoints (LiteLLM, vLLM, etc.) configured via config.json were therefore ignored for the OpenAI backend. - OpenAITranscriptionProvider.__init__ now accepts api_base with env fallback (OPENAI_TRANSCRIPTION_BASE_URL) matching the Groq pattern. - BaseChannel.transcribe_audio forwards self.transcription_api_base to OpenAI. - Tests mirror the existing Groq coverage: manager propagation for provider "openai", BaseChannel-to-provider argument passing, and provider default vs override for api_url. Fully backward-compatible: when api_base is None and the env var is unset, the default https://api.openai.com/v1/audio/transcriptions is used.

That test file already calls pytest.importorskip("nio") at module top, so it self-skips on Windows (where nio isn't installed) without also hiding 62 tests from Linux CI. - filesystem.py: hoist `import os` to the module top and drop the duplicate inline import in ReadFileTool.execute. Document the CRLF->LF normalization as intentional (primarily a Windows UX fix so downstream StrReplace/Grep match consistently regardless of where the file was written). - test_read_enhancements.py: lock down two new behaviors * TestFileStateHashFallback: check_read warns when content changes but mtime is unchanged (coarse-mtime filesystems on Windows). * TestReadFileLineEndingNormalization: ReadFileTool strips CRLF and preserves LF-only files untouched. - test_tool_validation.py: restore list2cmdline/shlex.quote in test_exec_head_tail_truncation. The temp_path-based form was correct, but dropping the quoting broke on any Windows path containing spaces (e.g. C:\Users\John Doe\...). CI runners happen not to have spaces so this slipped through. Tests: 1993 passed locally.

Fix the should_execute_tools docstring so it matches the actual code. The previous version said "Only execute when finish_reason explicitly signals tool intent" but the code also accepts finish_reason == "stop". Explain why (some compliant providers emit "stop" with legitimate tool calls — openai_compat_provider.py already mirrors this at lines ~633 / ~678 where ("tool_calls", "stop") are both treated as the terminal tool-call state). Without this, a strict "tool_calls"-only guard would regress 15 existing runner tests that construct LLMResponse with tool_calls but no explicit finish_reason (default = "stop"). 2. Add tests/providers/test_llm_response.py. This locks the three cases: - no tool calls -> never executes - tool calls + "tool_calls"/stop -> executes - tool calls + refusal / content_filter / error / length / ... -> blocked These are exactly the boundary cases the #3220 fix is about; without a test here a future refactor could silently revert the guard. Body + tests only, no behavior change beyond the existing PR's intent.

Instead: - Keep `required=["action"]` so `list`/`remove` stay callable. - Prefix `message`'s description with `REQUIRED when action='add'.` and `job_id`'s with `REQUIRED when action='remove'.` so LLMs see the real per-action contract up front. - Keep the improved runtime error message from the previous commit for the case an LLM still omits `message` on `add`. Also add `tests/cron/test_cron_tool_schema_contract.py` to lock in: - `list` and `remove` pass schema validation with no `message` - `add` with `message` passes - `add` without `message` surfaces the actionable runtime error - field descriptions carry the REQUIRED hints - top-level `required` stays `["action"]` Existing `tests/cron/test_cron_tool_list.py` cases bypass schema validation by calling `_list_jobs()` / `_remove_job()` directly, which is why CI didn't catch the regression; the new test goes through `ToolRegistry.prepare_call`. --- nanobot/agent/tools/cron.py | 9 +- tests/cron/test_cron_tool_schema_contract.py | 99 ++++++++++++++++++++ 2 files changed, 104 insertions(+), 4 deletions(-) create mode 100644 tests/cron/test_cron_tool_schema_contract.py diff --git a/nanobot/agent/tools/cron.py b/nanobot/agent/tools/cron.py index d8f90fd5..f1af59d7 100644 --- a/nanobot/agent/tools/cron.py +++ b/nanobot/agent/tools/cron.py @@ -18,8 +18,9 @@ from nanobot.cron.types import CronJob, CronJobState, CronSchedule "(e.g., 'weather-monitor', 'daily-standup').

Clients cannot access other sessions. +- **chat_id as capability**: see [Multi-chat multiplexing](#multi-chat-multiplexing). Auth on the WebSocket handshake is the single line of defense; callers who pass it can attach to any chat_id they know. - **TLS enforcement**: When SSL is enabled, TLSv1.2 is the minimum allowed version. - **Default-secure**: `websocketRequiresToken` defaults to `true`.
