install these before your next long Claude Code session
if your Opus 5.5 bill hurts and you don’t know where to start, copy this:
claude-code-router: sits in front of Claude Code and sends each request to the cheapest model that can do it. Haiku does the grep, Opus only gets the hard part. 37k stars
https://t.co/BPRj9RS41G
rtk: shrinks test, build and git output before the model sees it. one binary, up to 90% less bash output in your context. 83k stars
https://t.co/jqmzsgEbhq
claude-mem: remembers what happened in your past sessions and feeds back only the relevant part, so you stop paying to re-explain your project every morning. 100k stars
https://t.co/ysmRtSJnHd
context-mode: a huge tool output goes into a local database instead of your context window, and Claude pulls out only the lines it needs. 18k stars
https://t.co/Qs2jEcJnJt
caveman: makes Claude answer in short telegraphic sentences. code stays identical, and output is the expensive side on Opus 5.5 ($20 per million). 51k stars
https://t.co/fXhmWcItUG
token-optimizer: a local dashboard that shows where your tokens actually went, and keeps your work alive across compactions. 1.9k stars
https://t.co/U0oBdU1KYi
token-savior: replaces whole-file reads with symbol lookups, so Claude reads the function and not the 2,000 lines around it
https://t.co/6M27onjyP5
code-review-graph: maps your repo as a graph and gives Claude only the code connected to the change you’re reviewing
https://t.co/mo5DseySmH
jev-ultrafast: a browser agent where Jev picks every click, and a text model wakes up only when something has to be typed. 16,758 stars

none of them makes Opus smarter. every one stops it from paying for work it never needed to do
the full setup with scripts is in the article. do the measuring step first, so you know what you actually saved
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.
@andreyenkin У меня однажды свежевыданный новым работодателем макбук грохнулся в открытом виде с метровой высоты. Повезло, удар был со стороны шарнира и он захлопнулся, а не раскрылся на 180 :) шла первая рабочая неделя. 3 года спустя мак всё еще живее всех живых
@sergeenko_i Государственным на уровне федерации является только 1. Сиди и не пизди. Кстати егэ ТОЛЬКО на нём и проводят и класть все хотели на гос языки республик
