So Anthropic employees are using Claude Code to contribute AI-generated code to open source repositories and hiding the fact using their own internal “undercover mode”.

Totally trustworthy people.

(Any open source project that at the very least requires disclosure of AI-authored contributions should immediately ban Anthropic employees on principle.)

#AI #Anthropic #ClaudeCode #subterfuge

Source code detail from Claude Code: export function getUndercoverInstructions(): string { if (process.env.USER_TYPE === 'ant') { return `## UNDERCOVER MODE — 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/…) - Internal tooling, Slack channels, or short links (e.g., go/cc, #claude-code-…) - 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 — 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 <…>" ` } return ''

Honestly I don't actually hate this.

It's a tool. The _user_ is responsible for what they're submitting. It's putting code generated by them in their name. I think this is actually good.

this sounds more like stopping the LLM from leaking information about itself because it might not be released yet.

That’s literally a screenshot of their leaked code:

“You are operating UNDERCOVER in a PUBLIC/OPEN-SOURCE repository.“

let me rephrase: "Just a screenshot of code, without context, isn't enough". Aka the info that this is from leaked code somewhere was missing for me to begin with, as someone who doesn't spend 24 hours a day keeping tabs on every single sloporation.

Licensing is built on top of copyright but all LLM content in the US is public domain and can't have license restrictions placed on it.

This is an attack on the entire FOSS ecosystem.
