Opus 5.5 with Reverse Engineer Anything took about 5 minutes, using hopper, to tell me how the cheats in 3D Pinball for Windows work. Then it told me I should install ghidra and it was able to describe all the ball physics in about 2 minutes (starting fresh).

3D Pinball for Windows has obviously already been reverse engineered, and the agent itself speculated that it might not be able to credit all of its insight to active reasoning. but based on what other folks are saying, it works just as well on more difficult stuff.

this is obviously a huge deal. agents are very good at this and REA is an empowering interface. everything is open source now, at least kind of, for a one-time cost at pretty reasonable rates. my pinball experiment cost $3.29.

so ghidra worked better but I gotta say, hopper's UI opening, flashing a bunch of hex and assembly, and then closing quickly while the agent worked was extremely cyberpunk

agent commented that using the REA MCP server was the trick to going fast (otherwise with the CLI you keep expensively restarting ghidra over and over)

lmao codex bedrock hard-codes the auto-permissions model to global.openai.gpt-5.6-luna with no way to change it. at work we can only use us.* endpoints!

opus 5.5 on bedrock is shockingly unreliable. long outages the past 3 days. us.anthropic.claude-opus-5-5 specifically

I use AI an immense amount, every day, and I still do not understand at all how or why people have dozens of persistent agents constantly working. How many emails do you receive a day? How many projects have you amassed? Don’t you finish tasks? idgi. Maybe this is related to my not keeping tabs open

absolutely crushed our AI cost by pushing folks toward openai models for subagents. we let folks use opus or astra as they prefer, but insist on sol and luna subagents. we’ve gone from a nearly exponential trend to nearly flat, despite headcount growth

the economics of testing code is changing, imo. 2 minutes of testing to 60 minutes of coding makes total sense, but 2 minutes of testing to 30 seconds of coding is different. testing is more important than ever as we take our hands off the wheel, but which tests and when is important.

it's super neat that sibling agents can communicate easily in prime-agent but I don't feel like it actually helps. heavy coordination slows things down a lot, plus it's expensive. each agent message is two calls.

I feel like I'm hacking the gibson when it launches 10 subagents and half of those launch their own, but is it efficient? I don't think it would have taken 1 astra 90 minutes to do what I asked of it. time isn't the only axis to care about, but it's one of them

I think it's that Doom play can look proficient even when mildly sloppy, whereas rigid discrete games like tic-tac-toe and chess aggressively punish even a single bad move.

But still, I think it's pretty reasonable to be disappointed that it can't consistently identify optimal tic-tac-toe moves, at least in the (I think reasonable) harness I built

I know Jev can’t generate text but what would happen if you gave it a prompt, the alphabet as choices, plus what it had typed so far, in a loop? brb
