@0xChaseTM Thanks dude

loop engineering is prompt engineering with the human deleted.

17 minutes, free. everything you need on harness and loops, and nothing you already know.

02:52 → the 12 hour task that lies about finishing
04:06 → what harness actually is, in three parts
12:59 → a loop inside a loop inside a loop
16:36 → all 6 components on one screen

watch now, then read how to run this on opus 5 ↓

[Vampa @0xVampas]

New Boris Cherny’s Opus 5 playbook is 10 page long.

it opens with him deleting 80% of Claude Code’s system prompt and shipping it anyway:

“the model is actually a little bit more intelligent without these prompts”

he gave one prompt 15 days ago and hasn’t touched it since. it’s still running right now.

the stack:

Prompt → Context → Harness → Loop → Graph

step 1 → delete the entire system prompt on release day. not trim. delete
step 2 → run the real product on real work. never guess what the model needs
step 3 → restore a line only after the same failure shows up twice
step 4 → price every line you keep. the model reads it on every single call
step 5 → your CLAUDE.md, skills and hooks die every 6 months too

the receipts:
→ Bun’s runtime rewritten Zig to Rust in 11 days. one prompt, ~100k lines, in production today
→ nobody asked it to, but the desktop rewrite opened its own Slack channel to live-blog its progress
→ 30 loops now maintain 4 codebases daily. one of them is literally called abstraction police
→ CLAUDE_CODE_SIMPLE=1 strips every prompt including tool prompts. undocumented. go try it

book now, read tonight. tomorrow you delete 80% of your own prompt ↓

@0xChaseTM very usefull course

[Vampa @0xVampas]

@SkadooshGG yep bro

@0xMortyx More people really scary about ai replace humans. And her words getting calm a bit

@0x1mpulse great article bro, booked

@SkadooshGG thanks dude, its really gamechanger for your work with opus 5

Everyone is posting Opus 5 benchmarks.
Boris Cherny posted something else.

"the success rate for prompt injection attacks drops to ~0"

That's with defenses layered: alignment, injection probes,
Auto Mode in Claude Code.

Put it next to the other thing about Opus 5 and it checks its own
work and keeps going until the task lands.

A model that verifies itself and can't be talked out of the task
is the first one you can actually walk away from.

@0xMortyx it`s really usefull skills. i`ll use them

IBM just dropped a new 45-minute course on agent loops and why yours still isn't shipping faster:

0:58 – chatbots know. agents do
11:56 – they felt 20% faster. they shipped 20% slower
17:17 – the fix vibe-coding can't do
21:31 – "almost right, but not quite"
39:27 – the agent found what nobody wrote down

45 minutes of this beats most paid agent courses.

Watch it immediately and save to bookmarks

Opus 5 is a great model for coding, data analysis, design, biology, knowledge work.

More than any of these eval scores, what is most exciting to me is something else: Opus 5 is our least prompt injectable model yet. It is a bit buried in the system card, but across PI evals and red teaming, Opus 5 is very hard to prompt inject successfully.

And when layering defenses -- strong model alignment, combined with prompt injection probes, combined with Auto Mode in Claude Code -- the success rate for prompt injection attacks drops to ~0. This is new and exciting! More about this soon.
