CHANGELOG.md

@@ -5,6 +5,310 @@ All notable changes to **Pipecat** will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [Unreleased]
+
+### Added
+
+- Added the [Pipecat CLI](https://github.com/pipecat-ai/pipecat-cli) to the
+  required dependencies, enabling you to scaffold a new project directly from
+  `pipecat-ai`. Get started with:
+
+  ```bash
+  uv run pipecat init
+  ```
+
+- Expanded support for universal `LLMContext` to `AWSNovaSonicLLMService`.
+  As a reminder, the context-setup pattern when using `LLMContext` is:
+
+  ```python
+  context = LLMContext(messages, tools)
+  context_aggregator = LLMContextAggregatorPair(context)
+  ```
+
+  (Note that even though `AWSNovaSonicLLMService` now supports the universal
+  `LLMContext`, it is not meant to be swapped out for another LLM service at
+  runtime.)
+
+  Worth noting: whether or not you use the new context-setup pattern with
+  `AWSNovaSonicLLMService`, some types have changed under the hood:
+
+  ```python
+  ## BEFORE:
+
+  # Context aggregator type
+  context_aggregator: AWSNovaSonicContextAggregatorPair
+
+  # Context frame type
+  frame: OpenAILLMContextFrame
+
+  # Context type
+  context: AWSNovaSonicLLMContext
+  # or
+  context: OpenAILLMContext
+
+  # Reading messages from context
+  messages = context.messages
+
+  ## AFTER:
+
+  # Context aggregator type
+  context_aggregator: LLMContextAggregatorPair
+
+  # Context frame type
+  frame: LLMContextFrame
+
+  # Context type
+  context: LLMContext
+
+  # Reading messages from context
+  messages = context.get_messages()
+  ```
+
+- Added support for `bulbul:v3` model in `SarvamTTSService` and
+  `SarvamHttpTTSService`.
+
+- Added `keyterms_prompt` parameter to `AssemblyAIConnectionParams`.
+
+- Added `speech_model` parameter to `AssemblyAIConnectionParams` to access the
+  multilingual model.
+
+- Added support for trickle ICE to the `SmallWebRTCTransport`.
+
+- Added support for updating `OpenAITTSService` settings (`instructions` and
+  `speed`) at runtime via `TTSUpdateSettingsFrame`.
+
+- Added `--whatsapp` flag to runner to better surface WhatsApp transport logs.
+
+- Added `on_connected` and `on_disconnected` events to TTS and STT
+  websocket-based services.
+
+- Added an `aggregate_sentences` arg in `ElevenLabsHttpTTSService`, where the
+  default value is True.
+
+- Added a `room_properties` arg to the Daily runner's `configure()` method,
+  allowing `DailyRoomProperties` to be provided.
+
+- The runner `--folder` argument now supports downloading files from
+  subdirectories.
+
+### Changed
+
+- `CartesiaSTTService` now inherits from `WebsocketSTTService`.
+
+- Package upgrades:
+
+  - `daily-python` upgraded to 0.20.0.
+  - `openai` upgraded to support up to 2.x.x.
+  - `openpipe` upgraded to support up to 5.x.x.
+
+- `SpeechmaticsSTTService` updated dependencies for `speechmatics-rt>=0.5.0`.
+
+### Deprecated
+
+- The `send_transcription_frames` argument to `AWSNovaSonicLLMService` is
+  deprecated. Transcription frames are now always sent. They go upstream, to be
+  handled by the user context aggregator. See "Added" section for details.
+
+- Types in `pipecat.services.aws.nova_sonic.context` have been deprecated due
+  to changes to support `LLMContext`. See "Changed" section for details.
+
+### Fixed
+
+- Fixed an issue in `RivaSegmentedSTTService` where a runtime error occurred due
+  to a mismatch in the \_handle_transcription method's signature.
+
+- Fixed multiple pipeline task cancellation issues. `asyncio.CancelledError` is
+  now handled properly in `PipelineTask` making it possible to cancel an asyncio
+  task that it's executing a `PipelineRunner` cleanly. Also,
+  `PipelineTask.cancel()` does not block anymore waiting for the `CancelFrame`
+  to reach the end of the pipeline (going back to the behavior in < 0.0.83).
+
+- Fixed an issue in `ElevenLabsTTSService` and `ElevenLabsHttpTTSService` where
+  the Flash models would split words, resulting in a space being inserted
+  between words.
+
+- Fixed an issue where audio filters' `stop()` would not be called when using
+  `CancelFrame`.
+
+- Fixed an issue in `ElevenLabsHttpTTSService`, where
+  `apply_text_normalization` was incorrectly set as a query parameter. It's now
+  being added as a request parameter.
+
+- Fixed an issue where `RimeHttpTTSService` and `PiperTTSService` could generate
+  incorrectly 16-bit aligned audio frames, potentially leading to internal
+  errors or static audio.
+
+- Fixed an issue in `SpeechmaticsSTTService` where `AdditionalVocabEntry` items
+  needed to have `sounds_like` for the session to start.
+
+### Other
+
+- Added foundational example `47-sentry-metrics.py`, demonstrating how to use the
+  `SentryMetrics` processor.
+
+- Added foundational example `14x-function-calling-openpipe.py`.
+
+## [0.0.90] - 2025-10-10
+
+### Added
+
+- Added audio filter `KrispVivaFilter` using the Krisp VIVA SDK.
+
+- Added `--folder` argument to the runner, allowing files saved in that folder
+  to be downloaded from `http://HOST:PORT/file/FILE`.
+
+- Added `GeminiLiveVertexLLMService`, for accessing Gemini Live via Google
+  Vertex AI.
+
+- Added some new configuration options to `GeminiLiveLLMService`:
+
+  - `thinking`
+  - `enable_affective_dialog`
+  - `proactivity`
+
+  Note that these new configuration options require using a newer model than
+  the default, like "gemini-2.5-flash-native-audio-preview-09-2025". The last
+  two require specifying `http_options=HttpOptions(api_version="v1alpha")`.
+
+- Added `on_pipeline_error` event to `PipelineTask`. This event will get fired
+  when an `ErrorFrame` is pushed (use `FrameProcessor.push_error()`).
+
+  ```python
+  @task.event_handler("on_pipeline_error")
+  async def on_pipeline_error(task: PipelineTask, frame: ErrorFrame):
+      ...
+  ```
+
+- Added a `service_tier` `InputParam` to the `BaseOpenAILLMService`. This
+  parameter can influence the latency of the response. For example `"priority"`
+  will result in faster completions, but in exchange for a higher price.
+
+### Changed
+
+- Updated `GeminiLiveLLMService` to use the `google-genai` library rather than
+  use WebSockets directly.
+
+### Deprecated
+
+- `LivekitFrameSerializer` is now deprecated. Use `LiveKitTransport` instead.
+
+- `pipecat.service.openai_realtime` is now deprecated, use
+  `pipecat.services.openai.realtime` instead or
+  `pipecat.services.azure.realtime` for Azure Realtime.
+
+- `pipecat.service.aws_nova_sonic` is now deprecated, use
+  `pipecat.services.aws.nova_sonic` instead.
+
+- `GeminiMultimodalLiveLLMService` is now deprecated, use
+  `GeminiLiveLLMService`.
+
+### Fixed
+
+- Fixed a `GoogleVertexLLMService` issue that would generate an error if no
+  token information was returned.
+
+- `GeminiLiveLLMService` will now end gracefully (i.e. after the bot has
+  finished) upon receiving an `EndFrame`.
+
+- `GeminiLiveLLMService` will try to seamlessly reconnect when it loses its
+  connection.
+
+## [0.0.89] - 2025-10-07
+
+### Fixed
+
+- Reverted a change introduced in 0.0.88 that was causing pipelines to be frozen
+  when using interruption strategies and processors that block interruption
+  frames (e.g. `STTMuteFilter`).
+
+## [0.0.88] - 2025-10-07
+
+### Added
+
+- Added support for Nano Banana models to `GoogleLLMService`. For example, you
+  can now use the `gemini-2.5-flash-image` model to generate images.
+
+- Added `HumeTTSService` for text-to-speech synthesis using Hume AI's expressive
+  voice models. Provides high-quality, emotionally expressive speech synthesis
+  with support for various voice models. Includes example in
+  `examples/foundational/07ad-interruptible-hume.py`. Use with:
+  `uv pip install pipecat-ai[hume]`.
+
+### Changed
+
+- Updated default `GoogleLLMService` model to `gemini-2.5-flash`.
+
+### Deprecated
+
+- PlayHT is shutting down their API on December 31st, 2025. As a result,
+  `PlayHTTTSService` and `PlayHTHttpTTSService` are deprecated and will be
+  removed in a future version.
+
+### Fixed
+
+- Fixed an issue with `AWSNovaSonicLLMService` where the client wouldn't
+  connect due to a breaking change in the AWS dependency chain.
+
+- `PermissionError` is now caught if NLTK's `punkt_tab` can't be downloaded.
+
+- Fixed an issue that would cause wrong user/assistant context ordering when
+  using interruption strategies.
+
+- Fixed RTVI incoming message handling, broken in 0.0.87.
+
+## [0.0.87] - 2025-10-02
+
+### Added
+
+- Added `WebsocketSTTService` base class for websocket-based STT services.
+  Combines STT functionality with websocket connectivity, providing automatic
+  error handling and reconnection capabilities with exponential backoff.
+
+- Added `DeepgramFluxSTTService` for real-time speech recognition using
+  Deepgram's Flux WebSocket API. Flux understands conversational flow and
+  automatically handles turn-taking.
+
+- Added RTVI messages for user/bot audio levels and system logs.
+
+- Include OpenAI-based LLM services cached tokens to `MetricsFrame`.
+
+### Changed
+
+- Updated the default model for `AnthropicLLMService` to
+  `claude-sonnet-4-5-20250929`.
+
+### Deprecated
+
+- `DailyTransportMessageFrame` and `DailyTransportMessageUrgentFrame` are
+  deprecated, use `DailyOutputTransportMessageFrame` and
+  `DailyOutputTransportMessageUrgentFrame` respectively instead.
+
+- `LiveKitTransportMessageFrame` and `LiveKitTransportMessageUrgentFrame` are
+  deprecated, use `LiveKitOutputTransportMessageFrame` and
+  `LiveKitOutputTransportMessageUrgentFrame` respectively instead.
+
+- `TransportMessageFrame` and `TransportMessageUrgentFrame` are deprecated, use
+  `OutputTransportMessageFrame` and `OutputTransportMessageUrgentFrame`
+  respectively instead.
+
+- `InputTransportMessageUrgentFrame` is deprecated, use
+  `InputTransportMessageFrame` instead.
+
+- `DailyUpdateRemoteParticipantsFrame` is deprecated and will be removed in a
+  future version. Instead, create your own custom frame and handle it in the
+  `@transport.output().event_handler("on_after_push_frame")` event handler or a
+  custom processor.
+
+## Fixed
+
+- Fixed an issue in `AWSBedrockLLMService` where timeout exceptions weren't
+  being detected.
+
+- Fixed a `PipelineTask` issue that could prevent the application to exit if
+  `task.cancel()` was called when the task was already finished.
+
+- Fixed an issue where local SmartTurn was not being ran in a separate thread.

+# Community Integrations Guide
+
+Pipecat welcomes community-maintained integrations! As our ecosystem grows, we've established a process for any developer to create and maintain their own service integrations while ensuring discoverability for the Pipecat community.
+
+## Overview
+
+**What we support:** Community-maintained integrations that live in separate repositories and are maintained by their authors.
+
+**What we don't do:** The Pipecat team does not code review, test, or maintain community integrations. We provide guidance and list approved integrations for discoverability.
+
+**Why this approach:** This allows the community to move quickly while keeping the Pipecat core team focused on maintaining the framework itself.
+
+## Submitting your Integration
+
+To be listed as an official community integration, follow these steps:
+
+### Step 1: Build Your Integration
+
+Create your integration following the patterns and examples shown in the "Integration Patterns and Examples" section below.
+
+### Step 2: Set Up Your Repository
+
+Your repository must contain these components:
+
+- **Source code** - Complete implementation following Pipecat patterns
+- **Foundational example** - Single file example showing basic usage (see [Pipecat examples](https://github.com/pipecat-ai/pipecat/tree/main/examples/foundational))
+- **README.md** - Must include:
+
+  - Introduction and explanation of your integration
+  - Installation instructions
+  - Usage instructions with Pipecat Pipeline
+  - How to run your example
+  - Pipecat version compatibility (e.g., "Tested with Pipecat v0.0.86")
+  - Company attribution: If you work for the company providing the service, please mention this in your README. This helps build confidence that the integration will be actively maintained.
+
+- **LICENSE** - Permissive license (BSD-2 like Pipecat, or equivalent open source terms)
+- **Code documentation** - Source code with docstrings (we recommend following [Pipecat's docstring conventions](https://github.com/pipecat-ai/pipecat/blob/main/CONTRIBUTING.md#docstring-conventions))
+- **Changelog** - Maintain a changelog for version updates
+
+### Step 3: Join Discord
+
+Join our Discord: https://discord.gg/pipecat
+
+### Step 4: Submit for Listing
+
+Submit a pull request to add your integration to our [Community Integrations documentation page](https://docs.pipecat.ai/server/services/community-integrations).
+
+**To submit:**
+
+1. Fork the [Pipecat docs repository](https://github.com/pipecat-ai/docs)
+2. Edit the file `server/services/community-integrations.mdx`
+3. Add your integration to the appropriate service category table with:
+   - Service name
+   - Link to your repository
+   - Maintainer GitHub username(s)
+4. Include a link to your demo video (approx 30-60 seconds) in your PR description showing:
+   - Core functionality of your integration
+   - Handling of an interruption (if applicable to service type)
+5. Submit your pull request
+
+Once your PR is submitted, post in the `#community-integrations` Discord channel to let us know.
+
+## Integration Patterns and Examples
+
+### STT (Speech-to-Text) Services
+
+#### Websocket-based Services
+
+**Base class:** `STTService`
+
+**Examples:**
+
+- [DeepgramSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/deepgram/stt.py)
+- [SpeechmaticsSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/speechmatics/stt.py)
+
+#### File-based Services
+
+**Base class:** `SegmentedSTTService`
+
+**Examples:**
+
+- [RivaSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/riva/stt.py)
+- [FalSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/fal/stt.py)
+
+#### Key requirements:
+
+- STT services should push `InterimTranscriptionFrames` and `TranscriptionFrames`
+- If confidence values are available, filter for values >50% confidence
+
+### LLM (Large Language Model) Services
+
+#### OpenAI-Compatible Services
+
+**Base class:** `OpenAILLMService`
+
+**Examples:**
+
+- [AzureLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/azure/llm.py)
+- [GrokLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/grok/llm.py) - Shows overriding the base class where needed
+
+#### Non-OpenAI Compatible Services
+
+**Requires:** Full implementation
+
+**Examples:**
+
+- [AnthropicLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/anthropic/llm.py)
+- [GoogleLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/google/llm.py)
+
+#### Key requirements:
+
+- **Frame sequence:** Output must follow this frame sequence pattern:
+
+  - `LLMFullResponseStartFrame` - Signals the start of an LLM response
+  - `LLMTextFrame` - Contains LLM content, typically streamed as tokens
+  - `LLMFullResponseEndFrame` - Signals the end of an LLM response
+
+- **Context aggregation:** Implement context aggregation to collect user and assistant content:
+  - Aggregators come in pairs with a `user()` instance and `assistant()` instance
+  - Context must adhere to the `LLMContext` universal format
+  - Aggregators should handle adding messages, function calls, and images to the context
+
+### TTS (Text-to-Speech) Services
+
+#### AudioContextWordTTSService
+
+**Use for:** Websocket-based services supporting word/timestamp alignment
+
+**Example:**
+
+- [CartesiaTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/cartesia/tts.py)
+
+#### InterruptibleTTSService
+
+**Use for:** Websocket-based services without word/timestamp alignment, requiring disconnection on interruption
+
+**Example:**
+
+- [SarvamTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/sarvam/tts.py)
+
+#### WordTTSService
+
+**Use for:** HTTP-based services supporting word/timestamp alignment
+
+**Example:**
+
+- [ElevenLabsHttpTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/elevenlabs/tts.py)
+
+#### TTSService
+
+**Use for:** HTTP-based services without word/timestamp alignment
+
+**Example:**
+
+- [GoogleHttpTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/google/tts.py)
+
+#### Key requirements:
+
+- For websocket services, use asyncio WebSocket implementation (required for v13+ support)
+- Handle idle service timeouts with keepalives
+- TTSServices push both audio (`TTSRawAudioFrame`) and text (`TTSTextFrame`) frames
+
+### Telephony Serializers
+
+Pipecat supports telephony provider integration using websocket connections to exchange MediaStreams. These services use a FrameSerializer to serialize and deserialize inputs from the FastAPIWebsocketTransport.
+
+**Examples:**
+
+- [Twilio](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/serializers/twilio.py)
+- [Telnyx](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/serializers/telnyx.py)
+
+#### Key requirements:
+
+- Include hang-up functionality using the provider's native API, ideally using `aiohttp`
+- Support DTMF (dual-tone multi-frequency) events if the provider supports them:
+  - Deserialize DTMF events from the provider's protocol to `InputDTMFFrame`
+  - Use `KeypadEntry` enum for valid keypad entries (0-9, \*, #, A-D)
+  - Handle invalid DTMF digits gracefully by returning `None`
+
+### Image Generation Services
+
+**Base class:** `ImageGenService`
+
+**Examples:**
+
+- [FalImageGenService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/fal/image.py)
+- [GoogleImageGenService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/google/image.py)
+
+#### Key requirements:
+
+- Must implement `run_image_gen` method returning an `AsyncGenerator`
+
+### Vision Services
+
+Vision services process images and provide analysis such as descriptions, object detection, or visual question answering.
+
+**Base class:** `VisionService`
+
+**Example:**
+
+- [MoondreamVisionService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/moondream/vision.py)
+
+#### Key requirements:
+
+- Must implement `run_vision` method that takes an `LLMContext` and returns an `AsyncGenerator[Frame, None]`
+- The method processes the latest image in the context and yields frames with analysis results
+- Typically yields `TextFrame` objects containing descriptions or answers
+
+## Implementation Guidelines
+
+### Naming Conventions
+
+- **STT:** `VendorSTTService`
+- **LLM:** `VendorLLMService`
+- **TTS:**
+  - Websocket: `VendorTTSService`
+  - HTTP: `VendorHttpTTSService`
+- **Image:** `VendorImageGenService`
+- **Vision:** `VendorVisionService`
+- **Telephony:** `VendorFrameSerializer`
+
+### Metrics Support
+
+Enable metrics in your service:
+
+```python
+def can_generate_metrics(self) -> bool:
+    """Check if this service can generate processing metrics.
+
+    Returns:
+        True, as this service supports metrics.
+    """
+    return True
+```
+
+### Dynamic Settings Updates
+
+STT, LLM, and TTS services support `ServiceUpdateSettingsFrame` for dynamic configuration changes. The base STTService has an `_update_settings()` method that handles settings, and the private `_settings` `Dict` is used to store settings and provide access to the subclass.
+
+```python
+async def set_language(self, language: Language):
+    """Set the recognition language and reconnect.
+
+    Args:
+        language: The language to use for speech recognition.
+    """
+    logger.info(f"Switching STT language to: [{language}]")
+    self._settings["language"] = language
+    await self._disconnect()
+    await self._connect()
+```
+
+Note that, in this example, Deepgram requires the websocket connection be disconnected and reconnected to reinitialize the service with the new value. Consider if your service requires reconnection.
+
+### Sample Rate Handling
+
+Sample rates are set via PipelineParams and passed to each frame processor at initialization. The pattern is to _not_ set the sample rate value in the constructor of a given service. Instead, use the `start()` method to initialize sample rates from the frame:
+
+```python
+async def start(self, frame: StartFrame):
+    """Start the service."""
+    await super().start(frame)
+    self._settings["output_format"]["sample_rate"] = self.sample_rate
+    await self._connect()
+```
+
+Note that `self.sample_rate` is a `@property` set in the TTSService base class, which provides access to the private sample rate value obtained from the StartFrame.
+
+### Tracing Decorators
+
+Use Pipecat's tracing decorators:
+
+- **STT:** `@traced_stt` - decorate a function that handles `transcript`, `is_final`, `language` as args
+- **LLM:** `@traced_llm` - decorate the `_process_context()` method
+- **TTS:** `@traced_tts` - decorate the `run_tts()` method
+
+## Best Practices
+
+### Packaging and Distribution
+
+- Use [uv](https://docs.astral.sh/uv/) for packaging (encouraged)
+- Consider releasing to PyPI for easier installation
+- Follow semantic versioning principles
+- Maintain a changelog
+
+### HTTP Communication
+
+For REST-based communication, use aiohttp. Pipecat includes this as a required dependency, so using it prevents adding an additional dependency to your integration.
+
+### Error Handling
+
+- Wrap API calls in appropriate try/catch blocks
+- Handle rate limits and network failures gracefully
+- Provide meaningful error messages
+- When errors occur, raise exceptions AND push `ErrorFrame`s to notify the pipeline:
+
+```python
+from pipecat.frames.frames import ErrorFrame
+
+try:
+    # Your API call
+    result = await self._make_api_call()
+except Exception as e:
+    # Push error frame to pipeline
+    await self.push_error(ErrorFrame(error=f"{self} error: {e}"))
+    # Raise or handle as appropriate
+    raise
+```
+
+### Testing
+
+- Your foundational example serves as a valuable integration-level test
+- Unit tests are nice to have. As the Pipecat teams provides better guidance, we will encourage unit testing more
+

-### Setting up your editor
-
-This project uses strict [PEP 8](https://peps.python.org/pep-0008/) formatting via [Ruff](https://github.com/astral-sh/ruff).
-
-#### Emacs
-
-You can use [use-package](https://github.com/jwiegley/use-package) to install [emacs-lazy-ruff](https://github.com/christophermadsen/emacs-lazy-ruff) package and configure `ruff` arguments:
-
-```elisp
-(use-package lazy-ruff
-  :ensure t
-  :hook ((python-mode . lazy-ruff-mode))
-  :config
-  (setq lazy-ruff-format-command "ruff format")
-  (setq lazy-ruff-check-command "ruff check --select I"))
-```
-
-`ruff` was installed in the `venv` environment described before, so you should be able to use [pyvenv-auto](https://github.com/ryotaro612/pyvenv-auto) to automatically load that environment inside Emacs.
-
-```elisp
-(use-package pyvenv-auto
-  :ensure t
-  :defer t
-  :hook ((python-mode . pyvenv-auto-run)))
-```
-
-#### Visual Studio Code
-
-Install the
-[Ruff](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff) extension. Then edit the user settings (_Ctrl-Shift-P_ `Open User Settings (JSON)`) and set it as the default Python formatter, and enable formatting on save:
-
-```json
-"[python]": {
-    "editor.defaultFormatter": "charliermarsh.ruff",
-    "editor.formatOnSave": true
-}
-```
-
-#### PyCharm
-
-`ruff` was installed in the `venv` environment described before, now to enable autoformatting on save, go to `File` -> `Settings` -> `Tools` -> `File Watchers` and add a new watcher with the following settings:
-
-1. **Name**: `Ruff formatter`
-2. **File type**: `Python`
-3. **Working directory**: `$ContentRoot$`
-4. **Arguments**: `format $FilePath$`
-5. **Program**: `$PyInterpreterDirectory$/ruff`
