All Claude Code commits attributed to unknown user cjsys-ux

Problem

All Claude Code commits on GitHub display cjsys-ux as author. This affects 723+ commits across public and private repositories worldwide.

Cause

The GitHub account cjsys-ux (created Nov 13, 2025) has associated claude@anthropic.com with their profile. GitHub's attribution system links every commit with that email to their account.

• nostrband/keep.ai (5 commits)
• botfusions/sandaluciai (3 commits)
• toolkiterp/toolkit-fpna (private, multiple commits)

User impact:

• Every Claude Code user globally
• Both public and private repositories
• Commits dating to at least Nov 2025

Account details

• Username: cjsys-ux
• Created: 2025-11-13
• Public repos: 0
• Email: claude@anthropic.com (associated but likely unverified)
• Profile: https://github.com/cjsys-ux

Impact

Work attribution is broken. Commits appear authored by an unknown third party. Teams cannot identify Claude-assisted work. Private repositories show an unfamiliar user in their commit history, triggering security concerns.

The issue corrupts git history presentation across the entire platform.

Requested action

1. Verify whether cjsys-ux is an authorized Anthropic account
2. Remove the email association if unauthorized
3. Clarify the intended behavior for Claude Code commit attribution
4. Communicate resolution to affected users

Questions

• Is this account controlled by Anthropic?
• How did the association occur without email verification?
• Should Claude Code commits link to an official bot account?
• What is the timeline for resolution?

Reproduction

1. Create a commit using Claude Code in any repository
2. Push to GitHub
3. View commit on GitHub web interface
4. Observe author displayed as cjsys-ux
