Working on my own agentic environment that focuses on short lived agents and sandboxing. Agents are short lived and are spawned by the planner you're interacting with. This way models with low temp settings can focus on a single task, don't overflow, and produce actually good and readable code.

Only supports Go, specifically, due to unified formatting, codestyle, testing methodologies, core packages etc. Saves tons of tokens for system prompts to use Go.

Currently working on the summarizer agent and the requirements specifications, because I want to have the specifications check for valid Go syntax (using the upstream parser and ast package).

Warning, here be dragons:

I forked a simple DNLA server which has been dead for 10 years and updated it to .Net 9. The goal is that hard drives are too expensive now and so it's better to spin up media servers quickly and temporarily using whatever hardware you have on hand.

It currently builds and announces itself to my TV (can see the server in Roku Media Player) but crashes because the http server implementation is homemade and out of date. Copilot generated some options and I will be plugging an implementation of a sockets-based server in the next couple of days.

I added browser automation capabilities to sandvault [0], a MacOS sandbox, to allow AI agents to control Chrome browser from within the sandbox, which makes coding & testing websites from within the sandbox much easier.

I'm using sandvault+Claude to rebuild my personal blog, Code of Honor [1], because I got tired of WordPress. The site includes search functionality, and articles are automatically syndicated to Mastadon, BlueSky, and Twitter.

I wrote a Claude skill to automate testing of iOS apps [2], and it found issues in one of my released apps [3].

I'm building Envelope, which is a checking account with built-in budgeting: https://envelopebudgeting.com It's like if Mint, YNAB, or Copilot was built into a bank account. The goal is to help people budget, spend, and save from one account, instead of using a separate budgeting tool, spreadsheet (yuck!), or cash envelope system. It does that by allowing users to get paid via direct deposit and then organizing their money into digital envelopes for bills, groceries, savings, sinking funds, etc. It's attached to a debit card so everything updates instantly and has individual or joint accounts.

I'm currently working on the paycheck prediction algorithm so Envelope can automatically determine how much needs to be set aside from user's paychecks so their bills are paid on time.
