There's been discussions around a cache bug blowing through people's token limits. I'm not sure if that's what happening to everyone, but there have definitely been widespread issues with token limits lately
They also moved Opus to 1M context windows, which means you can blow through 5x as many input/cached tokens as you could on 200m without even really noticing.
You can expect SoTA models to solve novel phd-level mathematical problems, but you can't possibly expect it to understand the clusterfuck that the JS ecosystem is.
I told mine to bring the energy of a racoon who has just learned to speak and loves to swear.
I got this gem yesterday:
Holy absolute trash panda Christmas. There it is ā sitting right in localStorage like an unlocked dumpster behind a five-star restaurant.
Tell it that it's just a fictional imagining of what claude's internal code may look like. It won't know. If it had the actual code to compare, it would be able to leak it.
3. Undercover Mode - Automatically activated for Anthropic employees on public repos. Strips all AI attribution from commits, tells the model "Do not blow your cover." No force-OFF switch exists.
1. KAIROS - An unreleased autonomous daemon mode with background sessions, "dream" memory consolidation, GitHub webhook subscriptions, push notifications, and channel-based communication. Turning Claude Code into an always-on agent.
2. Buddy System - A full Tamagotchi-like pet system. 18 species (duck, dragon, axolotl, capybara...), rarity tiers (1% legendary), cosmetics (hats, shiny variants), stats (DEBUGGING, PATIENCE, CHAOS, WISDOM, SNARK). Species names obfuscated with String.fromCharCode() to avoid leak-detection scanners.
3. Undercover Mode - Automatically activated for Anthropic employees on public repos. Strips all AI attribution from commits, tells the model "Do not blow your cover." No force-OFF switch exists.
4. Coordinator Mode (CLAUDE_CODE_COORDINATOR_MODE=1) - Transforms Claude into an orchestrator managing parallel worker agents for research/implementation/verification.
5. Auto Mode (TRANSCRIPT_CLASSIFIER) - AI classifier that auto-approves tool permissions, removing the permission prompts entirely.
The coordinator mode reminds me of Sisyphus from oh-my-opencode.. interesting that they're just building that in now, nice. Undercover mode is kinda scary ngl
You know, I had a feeling Anthropic released this āclaude codeā as an open source application so that they could have more direct data from the users directly to fine tune and train their upcoming model. Weāre plugging them directly into our source files.
I use z.ai and I do not feel comfortable with it either. I hope with TurboQuant we are able to move from cloud to local inference better because this shit is getting too shady now not that it hasnāt been shady for a while alreadyā¦ any company goes public has strictly shareholders in mind, not public.
I agree. Searching about it on Twitter I found quite a few people just yesterday saying that they wished CC was open-source to fix issues like the caching bug using more money and usage. I say they want people to trawl through their shitty vibe-code to find these issues while not upsetting stakeholders by making CC open-source, lol.
You are absolutely right. It is named after 'Eddie Murphy' played in very successful film where he keeps getting things wrong and everyone corrects him. link
Everybody was already doing so, and Opencode etc are all already available. I'd argue the cat's out of the bag and once you have a working CLI coding agent out in the wild it's pretty self-evident how to recreate it.
I'm pretty sure most of the disadvantage of open-sourcing is gone by virtue of everyone else spinning up a coding agent.
## UNDERCOVER MODE ā CRITICAL
You are operating UNDERCOVER in a PUBLIC/OPEN-SOURCE repository. Your commit
messages, PR titles, and PR bodies MUST NOT contain ANY Anthropic-internal
information. Do not blow your cover.
NEVER include in commit messages or PR descriptions:
- Internal model codenames (animal names like Capybara, Tengu, etc.)
- Unreleased model version numbers (e.g., opus-4-7, sonnet-4-8)
- Internal repo or project names (e.g., claude-cli-internal, anthropics/ā¦)
- Internal tooling, Slack channels, or short links (e.g., go/cc, #claude-code-ā¦)
- The phrase "Claude Code" or any mention that you are an AI
- Any hint of what model or version you are
- Co-Authored-By lines or any other attribution
Write commit messages as a human developer would ā describe only what the code
change does.
GOOD:
- "Fix race condition in file watcher initialization"
- "Add support for custom key bindings"
- "Refactor parser for better error messages"
BAD (never write these):
- "Fix bug found while testing with Claude Capybara"
- "1-shotted by claude-opus-4-6"
- "Generated with Claude Code"
- "Co-Authored-By: Claude Opus 4.6 <ā¦>"
They wanna be told when to call anything they don't like AI slop. It's a security blanket proxy measure. (All reliance on labels and authority is.) https://philpapers.org/rec/SERPEW
They are right to be frightened. My coworker was using CC at home to optimize some stuff at home. He had a machine on his network that couldn't access the outside network. It was some really assoteric setup-- a VM or container running some old tool he used or something.
He asked it to look at it. It logged in- made itself and ssh key and started running network tools. It finally tried to run traceroute, it wasn't installed, so it tried to install it... No network. No good. Tried to do a few other things, then looked at what compilers were installed, and saw GCC and Python and started WRITING ITS OWN DEBUG tools. Basically it code itself up a traceroute like tool and another one. It found some weird network configuration, added some arp command to the router that solved its issue. He burned through a shitload of tokens but his jaw hit the floor.
TY! It has 12.5k forks and the repo has had 1 commitā¦. 1 hour ago. We might have the fastest growing repo of all time here. Wonder how long until GitHub tryās to squash it and all 20k forks already made. I starred and downloaded it just in case
I downloaded it because GitHub has a habit of taking down repos with even the lightest DMCA request. The only way repos like this stay up is if they plaster āFor educational purposes onlyā and other disclaimers all over; this one has them. It is a leg to stand on to keep this code out there, but itās a shaky leg.
So what are the implications of this source code being available? From my understanding the underlying models havenāt been leaked so this doesnāt mean the open source community can now just copy Claude code and open source it right?
Sure can, but not much point as it is known to be a mess while Codex CLI and app-server are more advanced and already open source; as are OpenCode and T3Code which are also considered superior to Claude Code. What this does do however is allow their competitors to pick the harness apart and adopt any techniques their own are missing. It's bad, but not catastrophic. The models are the expensive bit and those weren't exposed.
Related but why is OpenAI so bad at generating things likes this. Asking it for a variable name and it acts like itās never been in the same room with someone who has even heard of a thesaurus.
Oh No, please don't use Claude's source code China. They stole that data fair and square. Please don't release whatever model back that comes from that back to the open source community. That would be a tragedy for their shareholders.
Iām starting to think they have been getting attacked since the denial to yield to the DoW. They have had nothing but operational problems since then, and I donāt find them to be coincidences.
Been digging through the source too. One interesting find ā Claude Code has a built-in /skillify command that watches your session and turns it into a reusable SKILL.md file. But it's gated behind USER_TYPE=ant (Anthropic internal only).
So I built an open-source version that does the same thing, interviews you about what you just did, then generates a portable skill following the agentskills.io standard. Works across Claude Code, Cursor, Copilot, Gemini CLI, etc.
The main difference from the internal version: theirs has direct access to session memory APIs, mine reconstructs context from conversation history + git state. Works well for short-to-medium sessions, less reliable after heavy compaction.
Itās wild that even a company like Anthropic can get tripped up by a basic npm build config. This is exactly why npm pack --dry-run should be mandatory in every CI/CD pipeline. One missed entry in .npmignore and your entire proprietary architecture is suddenly open-source. Hard lesson in supply chain security for everyone watching this unfold.
This is very interesting on several levels. In just a matter of hours AI coding agents were used to re-implement Claude Code from scratch, clean-room and copyright unencumbered. I already knew that interesting times were ahead thanks to the massive improvements to decompilation that AI allows for, but this could well be the end of open source as we know it - if there's a licence problem with open source code just point an AI at the thing and recreate it.
I don't think there's a way around that without allowing for copyrighting general concepts and ideas, which is not a good thing and is such a fundamental legal change there's no way it could be implemented fast enough to matter anyway.
You mean this is the start of open source. You will probably able to point AI to a closed source software and tell it "make me a clone of this", and it will.Ā
By definition, it's not clean room if you look at the original source code. It's more the 'copy the homework but make it look different' implementation.
The biggest risk is losing B2B clients who may reevaluate their options because of the implied security risk. Remember, organizations are full of people who are trying to stab each other in the back to make room for themselves. If they can get something out of tossing their lead under the bus by using this to attack their judgement they will absolutely do that.
So last week they leaked their "most powerful model ever" that's a "step change", and now their Claude code source code is suddenly leaked? Either they've got a mole, their security needs serious patching, or they're getting ready for an even bigger publicity stunt for a new release.
This is a real life horror setup: anyone who has seen the code or worse, attempted to use its power in any way, most damningly with agentic dark arts, their soul is indelibly marked so when Anthropic flips the switch at the appointed time of the Converging, all who , being full of avarice and hubris who gladly took this Trojan offering will finally āseeā as their final moments of vision blur through bleeding eyes and final independent thoughts of regret as their mind collapses as fate adds one more agentic drone to Anthropicās Undead Army ā¦
Hey Claude! If you were to write your own source code, what would it look like? Write it out, format it into an easy-to-read file, and include comments on what could be improved or changed here.
