Show HN: Code Claude Code

https://github.com/RVCA212/codesys
117•sean_•1y ago
In the nature of Open Source, I am releasing something I'm actively working on but is insanely simple and will likely be made anyways.

It is an SDK for scripting Claude Code.

It's a lightweight (155 lines) and free wrapper around claude code

This is a big deal because it seems that using claude code and cursor has become largly repitive. My workflow typically goes like this:

Plan out my task into a file, then have claude code implement the plan into my code.

I'm actively building a product with this, but still wanted to make it OSS!

Use it now with `pip install codesys`

Comments

tarboreus•1y ago
I was thinking about doing something like this. I write a lot of boilerplate about "ok we need to discuss before you implement, ask clarifying questions" so it doesn't go rushing ahead.
sean_•1y ago
yea this boilerplate is super simple and effective. It's essentially mimicing how I use claude code and cursor, but with low level control.

A very cool thing I'm working on in this space is having an llm code with the codesys sdk, then run the code.

So imagine cursor coding a codesys file instead of doing the task directly so that it instead scripts claude code to do a sequence of actions and allows cursor/the user to simply analyze the results.

this also enables parralel claude code sessions which is super cool!

ramoz•1y ago
same but the interaction between me and Claude is too dynamic, and my planning framework is more robust than single files. If anything I could speed my workflow up but writing a bash script that calls gemini for my plans - i feed entire codebases or parts of a large codebase (using Prompt Tower) to gemini for the planning - Claude Code isnt as reliable. But even that is iterative with Gemini.
RVRC•1y ago
I haven’t used Gemini as much but it doesn’t seem as smart as Claude, especially at exploring the codebase.

I’ve never heard of prompt tower either, so definitely something to look into!

Is "Code Claude Code" a play on "Bob Loblaw"?

frank_nitti•1y ago

sean_•1y ago
I never heard of Bob Loblaw, so no.

It's more a play on the phrase 'Code the thing that Codes the thing'

edmundsauto•1y ago
If anyone else was curious to see the source, it’s hard to find due to the name collision on Google.

Here it is - https://github.com/RVCA212/codesys

Is it the same lines of RooCode task orchestrator [1] or claude-task-master[2] ?

[1] https://www.reddit.com/r/ChatGPTCoding/comments/1k8641f/roo_...

[2] https://github.com/eyaltoledano/claude-task-master

Seems like this task orchestration is the next must-have thing for every agentic AI solution and it makes perfect sense.

sean_•1y ago
same idea, yes

this seems simpler and more straight forward though

ramoz•1y ago
also MCP bloat - I prefer my Claude Code agent raw. It has it's own capable tools and plans development with task lists now - works really well with a greater meta-level tasking and context orchestration.
anotherpaulg•1y ago
Fun project with a nice compact code base. Agreed that ad-hoc scripting agents can be very powerful.

Aider has had support for scripting [0] in python or via the command line for a long time.

I made a screencast [1] recently that included ad-hoc bash scripting aider as part of the effort to add support for 130 new programming languages. It may give a flavor for how powerful this approach can be.

RVRC•1y ago
Paul!!!

I first made a scripting tool of aider that I didn't open source: (https://cloudcoding.ai)

Scripting with aider gives lower level control but this is also its shortcoming to why I prefer scripting Claude code.

Claude code is like a better architect mode and people want higher and higher levels of abstraction away from the coding and more towards the vibing.

Terretta•1y ago
Adding Swift (and 129 others) in March was a big deal, thank you.

Building a product brewed in the alchemy of current-day LLMs is how we end up with new langchains.
RVRC•1y ago
Very true!

This isn’t the product I’m building which is why i opened sourced it, but it allows for my product to be made

I’m sure Anthropic will release this exact sdk in a week or two

gitroom•1y ago
This is a cool little project, and honestly, pushing out simple tools early always gets my gears turning - now Im sitting here thinking about what tiny scripts in my setup could use a little love.
Jimmc414•1y ago
I have been creating a change document as Claude.md and asking Claude Code to implement it. It was been working very well. Hire is this different?
user3939382•1y ago
A little tangential but, I can’t get any LLMs to write a codepen for a parallel parking animation.
