- Added abort signal logging to the `listEvents` function in `calendar-tool.ts` to track if the operation was aborted during input streaming and output generation. - Removed unnecessary inheritance from `RequestContext` in `SvgJsonNode`, `XmlElementInfo`, `ProcessSVGResult`, `SymbolContext`, and `SymbolInfo` interfaces in `data-processing-tools.ts` and `find-symbol.tool.ts` for cleaner type definitions. - Enhanced logging in the `readCSVDataTool` to include message count during input start and availability. - Implemented abort signal handling in the `findSymbolTool` to log if the operation was aborted during input processing and output generation. - Improved the `weatherTool` to handle abort signals throughout the execution flow, including checks before geocoding and during weather fetching, with appropriate logging for cancellation events. - Added specific handling for `AbortError` in the `weatherTool` to log cancellation messages and update the progress writer accordingly.

Code Review
This pull request enhances several tools by adding support for abort signals, improving logging with abortSignal status, and introducing the onInputDelta lifecycle hook. The changes are generally good, improving observability and cancellation capabilities.
However, there is a critical issue in weather-tool.ts where getWeather is called with an incorrect number of arguments, which will lead to a runtime error. I've also pointed out a few medium-severity issues related to code consistency, robustness, and documentation formatting that should be addressed to improve maintainability. The removal of unnecessary RequestContext inheritance is a good cleanup.

This call to getWeather will fail at runtime. You are passing abortSignal as the third argument, but the getWeather function is only defined to accept two arguments (location and unit).
You need to update the getWeather function to accept the abortSignal and pass it to the underlying fetch calls. For example:
const getWeather = async (location: string, unit: 'celsius' | 'fahrenheit', abortSignal?: AbortSignal) => {
// ...
const geocodingResponse = await fetch(geocodingUrl, { signal: abortSignal });
// ...
const response = await fetch(weatherUrl, { signal: abortSignal });
// ...

The formatting of this log object is a bit inconsistent. For better readability, it's good practice to have the closing brace }); on a new line when the object properties are split across multiple lines. This should be applied consistently across the file.

Similar to the other tools in this file, the formatting of this log object could be improved for consistency and readability. When an object is multi-line, the closing brace }); should be on its own line.

The change to !((browserInstance?.isConnected()) ?? false) is a great improvement for null safety. However, the function still ends with a non-null assertion (browserInstance!). While it's unlikely to be null here, it's safer to handle this possibility explicitly. Consider throwing an error if browserInstance is still null after the launch logic, which would indicate a failure in chromium.launch.
async function getBrowser(): Promise<Browser> {
if (!((browserInstance?.isConnected()) ?? false)) {
if (browserInstance) {
await browserInstance.close().catch(() => {}) // Close the old instance if it's not connected
}
browserInstance = await chromium.launch({
headless: true,
chromiumSandbox: false,
})
}
if (!browserInstance) {
throw new Error('Failed to launch browser instance.');
}
return browserInstance;
