TL;DR: Meta's Muse Code announcement (specifically the persistent-log-so-you-can-resume-after-a-crash feature) prompted me to add the same basic idea to my own much smaller personal coding tool — took about an hour, saved real frustration the same week.
Read about Meta's Muse Code launch this week — a terminal coding agent that keeps a persistent log so it can resume after a crash instead of starting over. Small detail, but it made me look at my own weekend project and go "...I don't do that."
I've got a little personal tool that uses an LLM to help refactor small chunks of a codebase I maintain — nothing as sophisticated as what Meta shipped, just something that takes a task description, calls a model, and applies the suggested change. It works fine when everything goes smoothly. It works terribly when something crashes halfway through a multi-step task, because I hadn't built in any way to know what had already been done versus what still needed doing — it just... started over from scratch every time.
Reading about Muse Code's persistent event log wasn't some huge revelation technically — "log your steps so you can resume" is not a novel idea — but seeing a major company ship it as a named feature was the nudge that got me to actually go add it to my own much smaller tool, instead of continuing to shrug and re-run things manually when they failed.
Took about an hour: wrote each subtask's status to a local JSON file as it completed, checked that file on startup to skip anything already done. Not fancy. But the next time a multi-step refactor task died halfway through (which, predictably, happened within the same week), I didn't lose the work that had already succeeded.
I use RouteAI to access the specific coding-focused model I call for this (mainly because I didn't want to lock the tool into one provider), but that's a minor detail — the actual lesson here wasn't about which model or which API, it was "if a feature announcement makes you wince at your own setup, that wince is worth listening to."
