Claude code source code has been leaked via a map file in their npm registry! Code: …a8527898604c1bbb12468b1581d95e.r2.dev/src.zip

PSA: If you've been running out of Claude session quotas on Max tier, you're not alone. Read this. Some insane Redditor reverse engineered the Claude binaries with MITM to find 2 bugs that could have caused cache-invalidation. Tokens that aren't cached are 10x-20x more expensive and are killing your quota. If you're using your API keys with Claude this is even worse. This is also likely why this isn't uniform, while over 500 folks replied to me and said "me too", many (including me) didn't see this issue. There are 2 issues that are compounded here (per Redditor, I haven't independently confirmed this) : 1s bug he found is a string replacement bug in bun that invalidates cache. Apparently this has to do with the custom @bunjavascript binary that ships with standalone Claude CLI. The workaround there is to use Claude with `npx @anthropic-ai/claude-code` 2nd bug is worse, he claims that --resume always breaks cache. And there doesn't seem to be a workaround there, except pinning to a very old version (that will miss on tons of features) This bug is also documented on Github and confirmed by other folks. I won't entertain the conspiracy theories there that Anthropic "chooses" to ignore these bugs because it gets them more $$$, they are actively benefiting from everyone hitting as much cached tokens as possible, so this is absolutely a great find and it does align with my thoughts earlier. The very sudden spike in reporting for this, the non-uniform nature (some folks are completely fine, some folks are hitting quotas after saying "hey") definitely points to a bug. cc @trq212 @bcherny @_catwu for visibility in case this helps all of us.











𝗜 𝘀𝘁𝗶𝗹𝗹 𝗱𝗼𝗻'𝘁 𝘂𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱 𝗵𝗼𝘄 🤔 I more than doubled my revenue in the last month, going from 20k to 50k MRR. My goal was to finish this year with $40k MRR, but life is weird. This has been a crazy roller coaster. 𝗜 𝗰𝗼𝘂𝗹𝗱𝗻'𝘁 𝗱𝗼 𝗶𝘁 𝘄𝗶𝘁𝗵𝗼𝘂𝘁 𝗺𝘆 𝘀𝘂𝗽𝗽𝗼𝗿𝘁𝗶𝘃𝗲 𝘄𝗶𝗳𝗲! 😻 This amount of money is really life-changing, but now I can afford to hire people and expand my marketing. Churn is going to hit around 20 March, let's see how much I can grow it until then. (𝗧𝗵𝗶𝘀 𝗽𝗼𝘀𝘁 𝘄𝗮𝘀 𝘀𝗰𝗵𝗲𝗱𝘂𝗹𝗲𝗱 𝘄𝗶𝘁𝗵 𝗣𝗼𝘀𝘁𝗶𝘇 😉)
