I also have an "ask" script that I use daily to ask simple stuff, it can access websearch and webfetch, it's more than enough to parse logs, ask for commands, quick research on the internet, small stuff. https://github.com/mariocesar/dotfiles/blob/main/common/.loc...
I use haiku for things that needs to be quick, have really clear instructions.
I also have the habit of naming my sessions with `/rename`
Here is the script https://github.com/mariocesar/dotfiles/blob/main/common/.loc...
For more long work, I now use Fable to create a PLAN.md. I tell it to make a plan that will be executed by other models, and most of the time it ends up choosing Opus or Sonnet.
I didn't start doing this recently. Before that, I would just use the top model for everything. Splitting the work across different models depending on the task has helped a lot. They run faster, and I usually get much better results
Congrats again!
I've used other trackers, ones focused on CBT. My only suggestion is to allow text notes in each entry, so I can track emotional states or recurring thoughts
A big plus is that it also has an open-source Community Edition that you can self-host
I started with the cloud version, then moved to self-hosted because it wasn't a big effort for our team. We also reduced our monthly invoice by about 50% after the move.
We've seen similar waves with new technologies before: overexposing the pros, dismissing the cons, hyper-optimism, and people using a lot of jargon without saying much of substance. The difference this time is the scale of the impact and the volume around it.

Senior full-stack engineer & tech lead, 10+ yrs, Python/Django-first. I ship MVPs that reach production and stabilize/modernize legacy systems without breaking what works. Comfortable across backend, frontend, and infra.
Strong on SaaS, integrations and data flows: Zapier apps (Platform/CLI), ERPs, billing, CRMs, webhooks, ETL — plus LLM integrations (OpenAI/Claude). Years spent making systems talk to each other reliably.
Ex-Zapier (integrations), ex-Tesorio. Experience across SaaS, fintech, and e-commerce.

Two months ago, a local company reached out on LinkedIn. They help with the search. I'm not good at selling myself, so I gave it a shot.
They fixed my CV and LinkedIn, and started finding roles for me. Since then, I've had more interviews.
The market feels over-automated now. Too much noise, too many filters, too much AI. It's exhausting.

However, I really enjoy it!
Something I'm not able to do nicely is to sync browser profiles, I end up doing all the setup and login step by step, it takes me an hour or so
