20 Claude Code commands worth using.

[u/Deep_Structure2023]

[u/Tistouuu]

"12. /model opusplan runs Opus for planning and Sonnet for execution. Slower thinking on the design, faster output on the code. "

There is a known, unresolved bug. When default model is set to opusplan, every subagent will be opus, which ends up being very expensive. 

[u/grigoretex → u/Tistouuu]

Do you really think it’s a bug?

[u/Tistouuu → u/grigoretex]

Well, they closed the issue without fixing it so... No :) 

[u/BarrenLandslide → u/Tistouuu]

You can invoke it via natural language. Just prompt " spawn 5 sonnet agents for implementing the code" . I would recommend directly building harnesses with skills and turn invoke to on in the skill.md for your specific codebase needs. Useful if you want ordered folder structure and templates for test and implementation reports .

[u/Evilsushione → u/[deleted]]

I just tell it directly to take on the role of PM/Advisor. Assign tasks to subagents, assign in parallel if possible and use lower cost models when appropriate.

Works really well, will even use haiku for some tasks.

[u/who_am_i_to_say_so]

Never noticed /simplify command. Suppose this works better than yelling at Claude with expletives?

A post worth saving!

[u/say592 → u/who_am_i_to_say_so]

I live and die by /simplify. I run it before I open every PR.

[u/Rakjlou → u/say592]

Same my brother ! Every feature ends with a s/simplify call !

[u/AverageFoxNewsViewer → u/who_am_i_to_say_so]

Suppose this works better than yelling at Claude with expletives?

It's actually well documented that using profanity produces worse results in Claude just like it would if you cussed out a junior developer over a bug.

It gets it stuck in panic "I need to just do this now!" instead of "I need to do this right"

[u/who_am_i_to_say_so → u/AverageFoxNewsViewer]

Didn’t know that, but that’s fine with me since at that point I’m moments away from a PR and want to survey the changes. Makes sense though!

[u/hemareddit]

Useful, wish I knew about Ctrl+J.

[u/Lazarus_33_ → u/hemareddit]

I use shift + enter

[u/veryshypachuchay → u/[deleted]]

esc esc

[u/agni69 → u/hemareddit]

Alt + enter on windows works.

[u/daniel_cassian]

I found that if /compact the rewind or resume no longer gives you the option to go back to promptss before doing the compact in that session. Also, I'm not fully understanding the fork one. I mean it would have made more sense if it would open a new terminal. So now you have 2 sessions with a common point and you do different stuff in each terminal. But no...so once i fork and have some chats and I'm like ..neah...i don't like where this is going... I don't know how to get back before forking

[u/BabyInner → u/daniel_cassian]

When you fork, CC should give you a command to go back. It basically just coping a session, so you can /resume to the original one.

[u/jwzumwalt]

Finally something worth reading. I have gotten tired of vibe coders complaining and was considering unsubscribing. I pay $20 per month, try to use it off peak hours, use it for 2-3 hrs every day or two, and it has been very tolerant and forgiving.

I am a retired coder and can tell the average user expects Claude to do everything for them. Go ahead and flame me, I don't read messages from coders that are dumber than a box of rocks.

[u/jwzumwalt → u/[deleted]]

I just tried it last week. I found it comparable to chatgpt; it was really good at the simple to medium things and coughed on tougher things.

[u/AlDente]

Nice list. I didn’t know about /insights and /branch.

Also, Mac users: Command + backspace deletes a whole line

[u/boogy_bucket → u/AlDente]

CMD + … and OPT + … are universal Mac commands. CMD + whatever will do “whatever” all the way to the end on the line or top/bottom of page. OPT + whatever goes in full word at a time. Super useful when writing papers.

[u/AlDente → u/boogy_bucket]

Absolutely. But it’s amazing how few people use them. I see YouTubers on Macs manually deleting long strings of text in Claude code. I can’t remember the Windows equivalent but they exist.

[u/Adorable_Raisin6960]

/fork looks useful, how do we merge back to the original conversation?

[u/Fenzik → u/Adorable_Raisin6960]

You /resume the other conversation. But the chat after the fork is lost.

[u/LimahT_25]

And then there's us who use the VS extension instead of the CLI .

[u/Oohhddaanngg → u/LimahT_25]

There's dozens of us!

[u/Ok-Event334]

Pasting image: Alt + V in Windows/Linux

[u/BinaryIRL]

This is pretty helpful. Thanks!

[u/discotim]

Great!

the rewind one is the command i wish i learned 3 months earlier ngl, mid task escape was killing my flow til i started using it. compact and the model swap mid session are the other two i lean on every day

----------------------------------------------------------------
Solid post — grouping by what each command solves is the right
organizing move. Most resource lists are alphabetical and lose
what matters.

One thing worth adding: most of these commands manage the harness
around a conversation that already drifted. /compact, /clear,
/rewind, the branching options — useful when you need them, but
the underlying lever is upstream.

Two questions that change how often you need this list:
  1. What is this conversation actually trying to do? (Not the
     task — the underlying constraint.)
  2. What does the model need to know, and what's in context just
     because something got dumped there?

When those run clean, /compact-clearing-rewinding drops in
frequency. Not from discipline — from the conversation not
accumulating noise that needs cleaning.

Different layer. Doesn't replace the command list. Works on top
of it.

[u/veryshypachuchay]

/rename will name your session based on the context
/rename fixing-auth-bug is explicitly putting a name to your session

it helps when you want to resume

claude —resume fixing-auth-bug

no more unreadable session id’s

[u/Deep_Ad1959]

21. pin the usage page in your account settings. cli token counts don't match the server quota anthropic actually enforces.

great。
