One of the reasons why I have been thinking and writing this topic is because there is indeed a malaise among the team, which is along the lines of "AI agents are blowing up coding…

I just want to point out that Opus 4.5 actually knows this trick and will write the code to decode the IDs if it is working with GitHub's API lol

The happy path way of getting code out of Codex is a PR. This is emphatically not true for Cursor.

Lmarena isn't that useful anymore lol

I quite liked this article, actually, and I'm quite an MCP stan. These all seem like legitimate problems that the burgeoning ecosystem needs to figure out. Some of them will be log…

I mean, obviously you want to run the local CI in some isolated way. But it's not such a bad idea for many projects. At PyTorch, we have the reverse problem, it's basically infeasi…

No, in fact, codemcp can be thought of as a fancier version of the official filesystem MCP that Anthropic released. It's 100% MCP.

One thing I'll say, is that if I was going to make people pay API costs (like cline/claude code) I probably wouldn't actually make an MCP. The MCP box is pretty limiting, and I'm o…

I definitely agree that for current models, the problem is finding where the LLM has comparative advantage. Usually it's something like (1) something boring, (2) something where yo…

One problem with keeping the changes separate is the LLM usually wants to test the code with the incremental new changes. So you need a working tree that has all the new changes. B…

So I have liked the Claude Pro style rate limiting over credits that refresh monthly but mostly because I only get snatches of 1-2 hours while I am on baby leave so I never actuall…

The thing is that, as many junior engineers can attest, randomly blundering around can still give you something useful! So you definitely can get value out of AI coding with the cu…

I have used Cursor and my own MCP codemcp. Cursor has a lot of nice QoL that you can't get from an MCP package; the TAB is really good for traditional coding. Haven't used copilot …

When I posted this to Reddit there was a pretty lively discussion there: https://www.reddit.com/r/ChatGPTCoding/s/wRmnREUWzn

Cline has famously huge API token costs as it is profligate with context. Because codemcp plugs into Claude Desktop you only pay for your Claude Pro sub, similar to Cursor's pricin…

In my experience, the model is king, and codemcp will operate fairly similarly to Cursor with the same failure modes as Cursor due to Sonnet 3.7. One thing that I like about codemc…

Yeah, Sonnet 3.5/3.7 are doing heavy lifting. Maybe the SOTA Gemini models would do better, I haven't tried them. Generating correct patches is a funny minigame that isn't really s…

In fact, the test framework I was using at the time (jest) did in fact support this. But the person who had originally written the tests hadn't had the foresight to use snapshot te…

They are listed on one page right now! Haha

I'm surprised you managed to get Desktop running on Linux lol. You don't need the filesystem/git MCPs alongside codemcp; in fact, it's better not to have them so that Claude consis…

Hi Hacker News! One of the things about this blog that has gotten a bit unwieldy as I've added more entries is that it's a sort of undifferentiated pile of posts. I want some sort …

And if you don't like clicking, even once, check out my other project, Refined Claude :)

Most of the problem is installing the MCP servers, which is more annoying on Windows. https://github.com/ezyang/codemcp#getting-started has instructions that I've personally tested…
