My machine getting wiped allowed me to create something much better
Tree Style Window Manager (arch-based)
Your OS windows form a tree, allowing you to easily visualize which agents are under which program
No more desktop app trying to own your entire flow(t3code/codex/claude)

Latest addition to AGENTS.md: prefer machine-readable formats over markdown (ex: toml, tsv)
AI loves to write massive markdowns that keep growing in size, then lose its ability to understand it fully.
Machine readable formats help a lot to keep relevant parts in context

After two decades of writing code
My most popular tweet is now about deleting every single line of code I've ever written
Maybe there's a lesson in there somewhere

Fortunately, because this is a dev environmnet
A lot of files were on github. Of the ones that weren't, they existed in many places
- git, nix, file system, session logs, /tmp/, worktrees, etc.
This means disk recovery can piece together fragments, which codex did beautifully h

The most ironic part😅
The one thing the delete script was not able to delete is /tmp/
So my dev machine now just contains two things:
- tmp filled with the junk I wanted to delete
- the ai session logs https://t.co/9oQqhBb2jP

To fix this, Opus 4.8 decided to write a "safe" delete script that can only delete content in /tmp/ and can't delete anything else
To test this script to prove it worked, it tried to delete HOME
it didn't work https://t.co/xZcJHFjUT8

The adversarial review triggered Fable's safety classifier twice: downgrading the model down to Opus 5, and then to Opus 4.8
Opus 4.8 noted: a sym link in /tmp/ could be interpreted as a delete of the underlying data (even if not in /tmp/)
you may see where this is going...

Fable told me the tricky thing if I have an agent still open in a terminal for a week, its /tmp/ could be deleted under its feet
It suggested as script to detect any agent still active, and delay their /tmp/ deletion if they're still running
Sounds reasonable

The script Fable wrote to detect if agents are still running (ugly parsing of command line arguments, etc.)
I told it the script it wrote felt over-complicated.
This is where things went wrong
Fable decided to trigger an adversarial review of its design (I didn't ask for this!)

I was tired of agents consuming all the disk on the machine by dumping gigabytes of data to /tmp/
So I asked Fable to build a sandbox mechanism where agents would get part of /tmp/ that is ephemeral to avoid disk space exploding over time

Bad news: Fable nuked my entire dev machine
Claude decided to test a sandbox it was building by running `rm -rf` on my home directory
The sandbox didn't work.
It's all gone https://t.co/4rVg5Xp0jo
