What happens when you have a codebase made with claude using this setup and claude is down for let's say 8 hours? Are you able to efficiently, smoothly and productively take over the codebase?
After 1 hour you asked the question, I am reading the replies and the conclusion is: no, they cannot.
I assume it will be similar to when a person is out sick or on vacation. Another person on the team likely could take over the work for a day, but realistically it just sits until they're is back.
What happens if you get up in the morning and your car won't start? Do you walk to work?
AI should enhance your skills. If it's down and your first though is to buy another sub from a different vendor this might be a skill issue. (I'm afraid every day that this will happen to me btw.)
Claude Code CLI is just a software package, if Anthropic API is down you could always connect Deepseek/other provider API to Claude Code CLI...
Just use a fallback, like Codex CLI. Takes a little effort upfront to ensure your configuration is wired correctly for both harnesses, but it is pretty easy to get them 90% identical (there will almost always be some experimental / edge case features that differ across harnesses, but in my experience those are negligible in practice).
Some agent-written tools and modules are easily the best codebases I've worked with. Documented correctly to the T with various charts and explanations for everything, "start here" guides, concepts defined clearly, and very good Git commit messages.
Naturally you can also have a LLM one-shot a 14000 line PHP monstrosity - it's up to you still, LLM or not.
The main problem is that it'll probably be a waste of time to code anything yourself if Claude is back online in 8 hrs. It's like walking to the next bus stop when you missed your bus - it won't make you get home any sooner.
8 hrs will probably be better spent reading specs or checking things with stakeholders so the next features you let Claude implement are the ones the business actually wants.
if there is 8 hours of downtime (even before AI) I take that opportunity to do other codebase maintenance, debugging, file organization, renaming all the things I said I'd rename or take a break.
pre AI if my IDE was down for whatever reason I wouldn't switch IDE's, I would do something else.
A local model doesn't have downtime. No you can't be as hands off with it as something like Claude, but isn't that a good thing?
We have 3 big competitors in the space: Anthropic, Google and Microsoft. I think they can all use the same base configuration. So it's not that we are out of options here.
time for a day off!
In my experience the answer is "no". If I am reviewing some slop and I ask Claude's human babysitter why this class has these constructors, they don't have any idea. Without Claude they don't understand the output at any level.
What happens when you have a codebase made with gcc for let's say 8 hours? Are you able to efficiently, smoothly and productively take over the assembly code?
You could say the same thing about any always online software suite and it would be equally fair as we move into more agentic development workflows.
EX. Sure, you could go back to the old ways of using a drafting table for your engineering work if CAD went down but it would be exponentially slower…
Personally with my workflow I spend 30-60 minutes per Claude feature spec doc when I’m pair planning. If Claude goes down I would just prepare spec docs on my own until it came back online and then rapidly review them before calling the coding workflow.
