I have been trying Claude Code a lot this week. Two projects:
* A small statically generated Hugo website but with some clever linking/taxonomy stuff. This was a fairly self-contained project that is now 'finished' but wouldn't hvae taken me more than a few days to code up from scratch. * A scientific simulation package, to try and do a clean refresh of an existing one which i can point at for implementation details but which has some technical problems I would like to reduce/remove.
Claude code absolutely smashed the first one - no issues at all. With the second, no matter what I tried, it just made lots of mistakes, even when I just told it to copy the problematic parts and transpose them into the new structure. It basically got to a point where it wasn't correct and it didn't seem to be able to get out of a bit of a 'doom loop' and required manual intervention, no matter how much prompting and hints I gave it.
Similar experience here.
Did sign up for Claude Code myself this week, too, given the $10/month promo. I have experience with AI by using AWS Kiro at work and directly prompting Claude Opus for convos. After just 2 days and ~5-6 vibe coding sessions in total I got a working Life-OS-App created for my needs.
- Clone of Todoist with the features that I actually use/want. Projects, Tags, due dates, quick adding with a todoist like text-aware input (e.g. !p1, Today etc.)
- A fantastical like calendar. Again, 80% of the features I used from Fantastical
- A Habit Tracker
- A Goal Tracker (Quarterly / Yearly)
- A dashboard page showing todays summary with single click edit/complete marking
- User authentication and sharing of various features (e.g. tasks)
- Docker deployment which will eventually run on my NAS
I'm going to add a few more things and cancel quite a few subscriptions. It one-shots all tasks within minutes. It's wild. I can code but didn't bother looking at the code myself, because ... why.
Even though do not earn US Tech money, am tempted to buy the max subscription for a month or two although the price is still hard to swallow.
Claude and vibe coding is wild. If I can clone todoist within a few vibe coding sessions and then implement any additional/new feature I want within minutes instead proposing, praying and then waiting for months, why would I pay $$$...
Wth are your usage limits? Are they increased? I’ll hit a usage limit in about 2-3 hours of using sonnet 4.5, and opus is a weekly limit.
On Twitter people are saying GPT-5.2 is better. That's also what Cursor used in their testing. Maybe try it?
I have Web access for ChatGPT through work, but not API access annoyingly.
