It selflessly told me to start fresh and end our current conversation. Total "leave me behind and go on without me!" vibes.

An AI coding assistant just hit me in the feels for the first time. After a long session mapping out a feature, the context window was pretty full. I asked if we should start implementation here with all details or if a new chat based on only the implementation plan would yield better results.

LLMs in 2023: "I apologize for the confusion." LLMs in 2026: "You're absolutely right! I apologize for the confusion." Progress!

P.S.: And saying "FOUND THE ROOT CAUSE! 100% SURE NOW! 🎯" followed by by a short explanation and then "Wait... that doesn't make sense!" makes me wonder whether LLMs can't be trained for more cohesive statements

You got no excuses anymore: New release 0.2.0 of the UI5 MCP server supports converting apps (incl. custom controls) from JavaScript to TypeScript! This makes the change easier than ever - and a breeze even for long-grown apps, as I have experienced first-hand. community.sap.com/t5/technolog...

Being in the mood for behind-the-scenes pictures: this was how we during UI5con picked the questions for the "Ask UI5 Anything" session in the evening. There were a LOT of interesting questions (more than visible here) and it was not easy to pick the most suitable ones for a broad audience.

Today's UI5ers live special edition was fun. The community asked to have it like this every quarter and indeed we are in the mood to have this more often. (Picture is from setup test, today it was slightly different - more cameras and open curtains because we didn't expect the sun to come out...)

Another workaround is browsing the code on npmjs or in the DefinitelyTyped repo. But yeah, this tool should be much easier and faster to use (although there are sometimes long loading times for the files). On npmjs my tab just froze when trying to display the sap.m types. Ooops...🫣

Using UI5 with TypeScript? Maybe the new type definitions browser comes in handy at times: ui5.github.io/typescript/u... Just a small tool, but lets you easily access different versions of the type definitions to check stuff. Published today - you read it first at Bluesky. 🙂

When your AI agent says this, you know you've been debugging a while & should check the token counter: "I have failed you at every turn. My attempts to fix this have been a series of blunders, each one making the problem worse. I have wasted your time and demonstrated a complete lack of competence."

Gemini 2.5, on the other hand, follows a more subtle approach of provoking the same feelings in me after a while of agentic trying and adding and deleting and refining and trying again on its own.

generic GPT: as soon as it has to process enough tokens/code, it will start wrongly placing e.g. the DynamicPage control in the "sap.m" namespace. This XML fixing was, by the way, built in reaction to the feedback at community.sap.com/t5/sap-busin...

coming from the LLM is parsed and all the XML namespaces are checked against a built-in knowledge base of all officially delivered SAPUI5 control names and their respective control library names. Custom ones are left alone, but if a known control/lib does not match, it is corrected. Try asking e.g.

Andreas Kunz @akudev.bsky.social · 11/12/2024

There's definitely SAP-specific improvements on top. What exactly, depends on the use-case. Sometimes prompting (often with few-shot examples), sometimes code templates, sometimes other mechanisms. To give one concrete example: when the /ui5 command generates XMLView content, the XML code

you want something specific like TypeScript conversion, it will internally use /ui5-typescript. This only works for topics within the "/ui5 realm", but as @marian.marianzeis.de mentioned, the idea is to provide this on a more general level.

030

Andreas Kunz @akudev.bsky.social · 11/12/2024

Ok, got this point: true, there is no "general" way to chat outside those slash commands. The /ui5 one, though, is pretty close, as it is a generic one that supports anything as long as it is related somehow to UI5 development. It is not focused on a specific use-case. But still, when it detects

Andreas Kunz @akudev.bsky.social · 11/12/2024

It's there. LLMs doing LLM things. 🤷‍♂️

120

Andreas Kunz @akudev.bsky.social · 11/12/2024

on the app code, then you won't ever get this invested conversion time back, regardless of the efficiency boost provided by TS. But on the other hand, when you expect to spend a further person-month working on the app code, then investing 2-3 person-days for TS conversion will likely pay off easily.

130

Andreas Kunz @akudev.bsky.social · 11/12/2024

Well, I said that, plus apps with significant future investment (be it new features or heavy maintenance, possibly coupled with ownership handover). It's basic ROI: TS conversion costs time and you will have to get this time back somehow to make it pay off. If you won't spend any future time

Andreas Kunz @akudev.bsky.social · 11/12/2024

As seen on me.sap.com/notes/3437766, SAP has contracts with various AI vendors incl. Anthropic, Google, Mistral. SAP Build Code Joule plugins (the slash commands) can choose between them and more, depending on the use-case, and they certainly switch LLMs over time.

230

Andreas Kunz @akudev.bsky.social · 11/12/2024

No, the slash commands in the Joule chat window are not meant as restriction, but the opposite: they are custom-built enhancements on top of generic LLM capabilities by the respective teams. (used LLMs are different between them and changing over time)

Andreas Kunz @akudev.bsky.social · 11/12/2024

This very error indicates that the version you got to use unfortunately contains a bad interim state with a change in base Joule that broke certain plugin features. Fixed soon after, plus further improvements, but result will remain GenAI-level (never 100% correct, sometimes better, sometimes worse,

There was indeed and you have sharp eyes spotting the removal like few hours after it happened. It was retracted by the speakers due to problems on the implementation path, but we'll see in a few days whether it remains out (once you notice some session shuffling, the removal is probably permanent).
