Trying a claude skill in claude.ai to interact with Google Drive apis or GCP apis, but it seems like thats blocked for some reasons. Other apis / urls seem to work though, a bit weird. Maybe that's more Google itself blocking the requests, I guess.

Just built a skill for Claude to estimate Pub/Sub cost in GCP - it contains the actual pricing data and a python script to do accurate calculations. This is pretty cool stuff!

Turns out I was running my external hard-drive on the wrong port on my Mac Studio 🤪 And who fixed it? Claude Code.

Still amazed by what's possible with agentic tooling like Claude Code. This GitLab analysis tool was built from a single initial prompt plus ~3 error correction prompts. Built mostly in the background without me noticing in about 30 minutes. The main takeaway? Build more stuff for an audience of 1

However, Codex actually managed to figure out what's the issue. Claude Code was stuck at code level (fix that "migrate" task), trying to make it work - rather than zooming out a bit.

Codex and the Github CLI are not friends. Codex is defaulting to using curl, which fails for internal repos. Instructing it to use the Github CLI works, but is a bit clunky.

would be really surprised if that was working in the end - let's see :D (manually prompted to use subagents)

The lunar eclipse viewed from the „Müllberg Hummelsbüttel“ (former landfill turned into recreational area, and is one of highest elevations in Hamburg). About 200 people had the same idea, so it was Kind of crowded 😀
The kicker was a shooting star right next to the moon 💫 #hamburg #mondfinsternis
