-# Plugin Development Guide
-
-This guide explains how to create new plugins for the Superset Tools application.
-
-## 1. Plugin Structure
-
-A plugin is a single Python file located in the `backend/src/plugins/` directory. Each plugin file must contain a class that inherits from `PluginBase`.
-
-## 2. Implementing `PluginBase`
-
-The `PluginBase` class is an abstract base class that defines the interface for all plugins. You must implement the following properties and methods:
-
-- **`id`**: A unique string identifier for your plugin (e.g., `"my-cool-plugin"`).
-- **`name`**: A human-readable name for your plugin (e.g., `"My Cool Plugin"`).
-- **`description`**: A brief description of what your plugin does.
-- **`version`**: The version of your plugin (e.g., `"1.0.0"`).
-- **`get_schema()`**: A method that returns a JSON schema dictionary defining the input parameters for your plugin. This schema is used to automatically generate a form in the frontend.
-- **`execute(params: Dict[str, Any])`**: An `async` method that contains the main logic of your plugin. The `params` argument is a dictionary containing the input data from the user, validated against the schema you defined.
-
-## 3. Example Plugin
-
-Here is an example of a simple "Hello World" plugin:
-
-```python
-# backend/src/plugins/hello.py
-# [DEF:HelloWorldPlugin:Plugin]
-# @SEMANTICS: hello, world, example, plugin
-# @PURPOSE: A simple "Hello World" plugin example.
-# @LAYER: Domain (Plugin)
-# @RELATION: Inherits from PluginBase
-# @PUBLIC_API: execute
-
-from typing import Dict, Any
-from ..core.plugin_base import PluginBase

-        else:
-            print(f"Hello, {name}!")
-```
-
-## 4. Logging with TaskContext
-
-Plugins now support TaskContext for structured logging with source attribution. The `context` parameter provides access to a logger that automatically tags logs with the task ID and a source identifier.
-
-### 4.1. Basic Logging
-
-Use `context.logger` to log messages with automatic source attribution:
-
-```python
-from typing import Dict, Any, Optional
-from ..core.plugin_base import PluginBase
-from ..core.task_manager.context import TaskContext
-
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        # Use TaskContext logger for structured logging
-        context.logger.info("My plugin is running!")
-    else:
-        # Fallback to global logger for backward compatibility
-        from ..core.logger import logger
-        logger.info("My plugin is running!")
-```
-
-### 4.2. Source Attribution
-
-For better log organization, create sub-loggers for different components:
-
-```python
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        # Create sub-loggers for different components
-        api_log = context.logger.with_source("api")
-        storage_log = context.logger.with_source("storage")
-        
-        api_log.info("Connecting to API...")
-        storage_log.info("Saving file...")
-    else:
-        # Fallback to global logger
-        from ..core.logger import logger
-        logger.info("My plugin is running!")
-```
-
-### 4.3. Log Levels
-
-The logger supports standard log levels. Use them appropriately:
-
-| Level | Usage |
-|-------|-------|
-| `DEBUG` | Detailed diagnostic information (API responses, internal state). Only visible when log level is set to DEBUG. |
-| `INFO` | General operational messages (start/complete notifications, progress updates). |
-| `WARNING` | Non-critical issues that don't stop execution (deprecated APIs, retry attempts). |
-| `ERROR` | Failures that prevent an operation from completing (API errors, validation failures). |
-
-```python
-# Good: Use DEBUG for verbose diagnostic info
-api_log.debug(f"API response: {response.json()}")
-
-# Good: Use INFO for operational milestones
-log.info(f"Starting backup for environment: {env}")
-
-# Good: Use WARNING for recoverable issues
-log.warning(f"Rate limit hit, retrying in {delay}s")
-
-# Good: Use ERROR for failures
-log.error(f"Failed to connect to database: {e}")
-```
-
-### 4.4. Progress Logging
-
-For operations that report progress, use the `progress` method:
-
-```python
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        total_items = 100
-        for i, item in enumerate(items):
-            # Report progress with percentage
-            percent = (i + 1) / total_items * 100
-            context.logger.progress(f"Processing {item}", percent=percent)
-    else:
-        # Fallback
-        from ..core.logger import logger
-        logger.info("My plugin is running!")
-```
-
-### 4.5. Logging with Metadata
-
-You can include structured metadata with log entries:
-
-```python
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        context.logger.error(
-            "Operation failed",
-            metadata={"error_code": 500, "details": "Connection timeout"}
-        )
-    else:
-        from ..core.logger import logger
-        logger.error("Operation failed")
-```
-
-### 4.6. Common Source Names
-
-For consistency across plugins, use these standard source names:
-
-| Source | Usage |
-|--------|-------|
-| `superset_api` | Superset REST API calls |
-| `postgres` | PostgreSQL database operations |
-| `storage` | File system operations |
-| `git` | Git operations |
-| `llm` | LLM API calls |
-| `screenshot` | Screenshot capture operations |
-| `migration` | Migration-specific logic |
-| `backup` | Backup operations |
-| `debug` | Debug/diagnostic operations |
-| `search` | Search operations |
-
-### 4.7. Best Practices
-
-1. **Always check for context**: Support backward compatibility by checking if `context` is available:
-   ```python
-   log = context.logger if context else logger
-   ```
-
-2. **Use source attribution**: Create sub-loggers for different components to make filtering easier in the UI.
-
-3. **Use appropriate log levels**:
-   - `DEBUG`: Verbose diagnostic info (API responses, internal state)
-   - `INFO`: Operational milestones (start, complete, progress)
-   - `WARNING`: Recoverable issues (rate limits, deprecated APIs)
-   - `ERROR`: Failures that stop an operation
-
-4. **Log progress for long operations**: Use `progress()` for operations that take time:
-   ```python
-   for i, item in enumerate(items):
-       percent = (i + 1) / len(items) * 100
-       log.progress(f"Processing {item}", percent=percent)
-   ```
-
-5. **Keep DEBUG logs verbose, INFO logs concise**: DEBUG logs can include full API responses, while INFO logs should be one-line summaries.
-
-## 5. Testing
-
-To test your plugin, simply run the application and navigate to the web UI. Your plugin should appear in the list of available tools.
