clai: Add ability to continue last conversation

[uriyyo]

Hi,

Thanks for clai, I'm using it all the time 🙌

One minor feature that I miss is the ability to continue the last conversation, cause my usage looks like this:

clai "first question"
clai "next question that basically related to first one"

So now it will be possible:

clai "first question"
clai -c "next question that basically related to first one"

I'm not sure if -c is a good option name, as it is usually used for configuration, so maybe -r/--resume would be a better option. I will be happy to update the implementation with better naming.

PR Change Summary

Added the ability to continue the last conversation in the clai CLI tool.

• Introduced the '-c' option to continue the last conversation instead of starting a new one.
• Updated usage instructions in the README to reflect the new option.
• Provided a suggestion for renaming the option to '-r/--resume' for clarity.

If you just want to ignore it on this PR, you can add the hyperlint-ignore label to the PR. Future changes won't trigger a Hyperlint review.

Note specifically for link checks, we only check the first 30 links in a file and we cache the results for several hours (for instance, if you just added a page, you might experience this). Our recommendation is to add hyperlint-ignore to the PR to ignore the link check for this PR.

I don't know why coverage is not 100%(

Hi @uriyyo 👋 Good to see you here. :)

Instead of just continuing the last conversation, can we select the session we want to continue? It would be nice to have a drop-down where the user could select the session. We can use the prompt-toolkit package for it.

@Kludex Long time no see, good to see you again!

Can we extend this with: #1981 @uriyyo @Kludex

@Kludex Sounds interesting, any suggestions on how it should look like?

I imagine adding input query slugify that will assign session specific slug, and then you can continue session based on a generated slug.

For instance if we are doing query like this:

clai "How to start thread in python?"

Slug might look like this - python-start-thread (eventually it will be generated by LLM).

And then you can continue this session:

clai "and how can I start 10 threads" --session python-start-thread

Also, it makes sense to add /sessions and maybe /session [session] commands for interactive mode?

Where:
/sessions - show list of available sessions.
/session - show info about the current session.
/session $session-name - switch to a specific session.

I still would love to have ability to continue just last conversation, but it can be implemented around sessions.

I'm sorry. I thought I had replied.

I think we can store the session with an uuid as file name, and then when resuming, we should see the first message truncated as part of that selection. This selection should be using prompt-toolkit.
