Set boundaries for your project. Tell the world.

It's officially #MaintainerMonth! To celebrate, I just published psas.dev which has README badges maintainers can use to communicate boundaries for their #opensource projects.

Every time I switch AI tools, I start from zero. I'm starting to think that I can't be the only one feeling this frustration.
Here's a small example...I recently used an AI tool to build a presentation and the AI kept structuring slides in ways that didn't match how I actually present. It was text heavy, wrong flow, missing my voice. It had no idea how I work because it had no context about my previous presentations. I stopped and built the slides manually.
My problem is that my context is locked up somewhere else. I've spent hours with Claude, ChatGPT and Gemini and none of that travels with me when I jump into a different tool.
And this is happening everywhere now. Most of the SaaS apps I use daily are adding AI powered features by the same foundational models. But when I use those features, they start from zero. They don't know anything about how I work or what I need.
What I actually want is control over my own context, locally. Build it once, keep it with me, and selectively share pieces with whatever tool I'm using. When a new model comes out that's better for my specific task, I want to test it without rebuilding my entire workflow from scratch. When I open an app with AI built in, I want to drip in just enough context to make it useful without explaining myself all over again.
Right now it works backwards. The tools own my memory. I'm stuck rebuilding context in every new app, every new conversation, every new project. And when the AI doesn't have that context, it's not useful to me at all.
I've been researching tools like Mem0 and SuperMemory but they feel more like tools an engineer would use to build an app. I know folks like Dharmesh Shah of HubSpot have written about this and he seems optimistic about where the solutions are headed.
Has anyone found a better way to manage context across multiple AI tools?](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:z64wjxpxaicyz5mf76b4eupc/bafkreie7v2rdasjgqmcfrau3sodygt5q3dmafbuk3pqsh46zznqzumsssm@jpeg)

This thread reminds me of Excel's formula evaluator, which lifts the values of each expression into the current context.
It's so helpful for the debugging to come to me, where I retain full context.

Forgetting the --𝚛𝚖 option when running throwaway #docker containers can clutter your computer.
But there is a short #bash command to remove all those stopped containers
docker rm $(docker ps -a | grep Exited | cut -d " " -f 1)

If the test suite crashes locally, it's hard to convince someone to write tests...
Ran into exactly this recently. We have a major test suite which executes inside a Docker container to match our production environment, but those tests stopped booting on a coworker's laptop.

There's something beautiful about watching #playwright auto-click across a browser.
Or maybe I'm simply grateful that I don't have to personally click thousands of buttons to export data from an old application that doesn't provide an API...

Now with dedicated commands for promotions to a new \𝚛𝚘𝚕𝚎, an academic \𝚍𝚎𝚐𝚛𝚎𝚎, an \𝚊𝚠𝚊𝚛𝚍 or accolade, and a personal \𝚙𝚛𝚘𝚓𝚎𝚌𝚝.
Spacing and formatting has also updated for better readability.
