THIS IS ACTUAL F*CKING GOLD
Anthropic just shared one of the best tricks for Claude Code.
The idea: run Sonnet, Haiku and Opus 5.5 together, each one doing only the job it's best at.
Opus-level judgment on every big call, without paying Opus rates for every routine turn.
You just launch Claude Code like this:
claude --model sonnet --advisor opus
here's the split:
→ Sonnet 5.5 runs the session and writes the code
→ Haiku 5.5 explores files and docs in parallel
→ Opus 5.5 stays on call as advisor for the big calls
→ you stop spending Opus on work that doesn't need it
Opus only steps in at three moments:
→ before a plan locks
→ when the same error shows up twice
→ before calling it done
Sonnet builds. Haiku explores. Opus reviews.
JEV engineering is the same move one layer down: the forks that need no thinker (which file, which tool, retry or stop) go to JEV in milliseconds, and the big models only see the ones that split
the full tree
> Sonnet 5.5 runs the main session and edits code
> search maps the repo on Haiku 5.5
> grep finds call sites on Haiku 5.5
> docs pulls the API reference on Haiku 5.5
> Opus 5.5 on call as advisor, reads the whole transcript when consulted
> JEV routes micro-forks in milliseconds
paste the tree and this prompt into Claude Code ↓
"Rebuild my Claude Code setup around this tree:
1. Run the main session on Sonnet 5.5 with Opus 5.5 as advisor.
2. Create three read-only Haiku 5.5 subagents: search (maps the repo), grep (finds call sites), docs (pulls the API reference).
3. Add one rule to CLAUDE.md: consult the advisor before locking a plan, after the same error twice, and before calling a task done.
4. Route fast deterministic forks (tool choice, path selection, retries) through JEV.
Show me every change as a diff first. No edits until I say go."

save it, you'll use this every single day.
Pages 4-7/7
Finally, everything is done. Apparently, it's only 7 pages. I miscounted because of one stupid sketch I gave to a friend as a joke wkwkkwkwwk
Opus 5.5 on Max effort - "make a dynamic 15-second motion graphics video that shows what an incredible motion designer you are, like it's your showreel for a résumé. go all out."
We have seen such an immense swell of demand that we have to temporarily pause signups for Jev. We need to ensure quality of service for our existing signups, which will continue to function. We are working diligently to ensure open access to Jev for everyone as soon as we can. Thank you.

Hay un catálogo de máquinas vulnerables, montadas a propósito, donde puedes practicar intrusión sin cometer ningún delito.
Laboratorios gratis, entorno real.
Y cuando te atascas, existen las soluciones escritas paso a paso.
Imagina poder conectar dos máquinas directamente con un simple token:
Sin cuenta de Tailscale.
Sin VPN.
Sin abrir puertos.
Sin root.
Sin configurar rutas ni DNS.
[Tailcat]
Reutiliza WireGuard + NAT traversal + DERP para crear un túnel cifrado entre dos máquinas.
Y luego puedes hacer cosas como:
→ Pasar datos entre equipos
→ Exponer puertos locales
→ Conectarte por SSH
→ Crear un SOCKS5 proxy
→ Actuar como exit node
→ Transferir archivos desde el navegador
→ Incluso usar tu propio relay DERP
Además, si NAT traversal funciona, Tailcat intenta convertir la conexión en P2P directo; si no, utiliza DERP como fallback.
Todo esto como un proyecto open source en Go.
