Claude Code and Codex both run untrusted commands. This post compares how their sandboxes protect your repo, secrets, and host machine.

quite interesting post

Fair criticism. I don’t think the value is just "agents can send text to each other”; that part has many implementaton and design choices. The value of h5i I’m exploring is making the intermediate state reviewable: review requests, risks, handoffs, unresolved claims, associated prompts and AI-to-Ai conveersation, and final decisions tied to the branch/PR.

I've been tracking real-world AI agent failures and incidents recently.

Things like:

prompt injection → goal hijacking

agents going rogue due to misalignment

unintended/unsafe tool use

It feels like we're starting to see repeatable patterns, not just isolated bugs.

I'm collecting cases + papers here:

If you've seen interesting incidents, weird failures, or relevant research, I would love to add them.
