Total cost: $0 beyond the $20/mo Pro sub. When I hit usage limits I just paused the loop and restarted the next day.

Takeaways:
* Short scoped sessions > one long session. Avoids compaction and keeps the agent focused.
* External state tracking (PLAN.md) is key. Nothing is lost between sessions.
* The agent wrote 836 tests. More than any human would, but not a bad thing for autonomous work.

It worked surprisingly well. ~50 loop iterations later, the project was functional. Opus reviewed the codebase midway and found no major deviations from the spec.

Some manual fixes were needed (CI issues, symlinks, default branch naming) but the core build was fully autonomous.

The setup: write a detailed spec with Opus, break it into small tasks in a PLAN markdown file, then run Sonnet in a while loop to code - one task per session, no human intervention.

Each session reads the plan, picks the first uncompleted task, implements it, writes tests, commits, and exits.

Dispatch from the Frontier - Adventures in AI Engineering AI engineering a greenfield project (gitgym) with Claude Code

New blog post: “Dispatch from the Frontier - Adventures in AI Engineering”
I let Claude Code autonomously build an entire project from scratch using ralph loops. Here’s how it went and what I learned 🧵

Precision & Recall Recall and precision classification metrics tutorial

Precision and recall: 2 metrics I always had to google because I could never remember which one was which. Eventually I found a way to keep them straight and wrote it down in case it helps someone else.
Plus: when to use them instead of just memorizing equations

My Most Useful VSCode Shortcuts VSCode productivity improvement with shortcuts, snippets, and extensions

Since (partially) upskilling on VSCode keyboard shortcuts I feel like I’m able to move around the editor quicker and with fewer interruptions. Wrote about this here: enerrio.bearblog.dev/vscode-short...

Wrote about Rich progress bars as an alt to tqdm. You can get some really cool and info packed bars with a little customization. Worth the timing trade off imo
