de-claude

A tool for removing references to AI assistants from a Git repository, including commit text, branch names, configuration files, comments, and pull-request or issue content. Git is the version-control system that records code history.

In plain words
What is it for?
Use it to remove assistant-related commit trailers, rewrite commit messages or history, rename branches, clean configuration, and edit AI-narrating comments.
Why use it?
It helps clean repository history and project text when those references should no longer appear.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

de-claude scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

de-claude: remove AI fingerprints from a repository

humanizer fixes prose. This fixes everything a repo leaks besides prose: trailers, authorship, history, branch names, config files, and comments that narrate a diff. When a commit message body needs prose work, use humanizer on the body and come back here for the mechanics.

The single most important rule: rewriting history is destructive and cannot be undone once you have deleted the backups. Read "Scope before you touch" first, every time. A repo that is merely embarrassing is recoverable. A repo whose shared history you rewrote without asking is a Monday morning outage for everyone else who cloned it.

What actually leaks

Ordered by how reliably it identifies a tool. The top group is a fingerprint. The bottom group is a guess.

Tier 1: unambiguous

  • Commit trailers. Co-Authored-By: Claude <[email protected]>, Co-Authored-By: Claude Opus 4.8 <[email protected]>, Co-authored-by: Cursor Agent, Co-authored-by: Copilot, Co-authored-by: openai-codex[bot].
  • Generated-with footers in commits, PR bodies, and issue bodies: 🤖 Generated with [Claude Code](https://claude.com/claude-code), Generated with Cursor, Created by Devin.
  • Bot authorship. Check author and committer separately. [email protected], [email protected], *[bot]@users.noreply.github.com, devin-ai-integration[bot].
  • Branch names: claude/*, cursor/*, codex/*, devin/*, copilot/*.
  • Assistant config committed by accident: .claude/, CLAUDE.md, .cursor/, .cursorrules, .aider*, .github/copilot-instructions.md, .windsurfrules, AGENTS.md, .specstory/.
  • Attribution in docs: "Built with Claude Code", "This project was generated by...".

Tier 2: strong but circumstantial

  • Em dashes in commit subjects. Almost nobody reaches for in a terminal.
  • Commit bodies with bolded inline headers, or **Changes:** followed by a bulleted rule of three.
  • Subjects in Title Case, or subjects over ~72 chars that read like documentation.
  • Emoji-prefixed subjects in a repo that has no gitmoji convention.
  • A body that explains the why of something trivial at three-paragraph length.
  • Suspiciously uniform commit cadence: forty commits in one hour, every message the same shape.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

de-claude is a skill published in the GitHub repository XyrusCode/ai-sync (2 stars, last pushed 2d ago), licensed MIT. It adds 111 tokens to every session and 4,835 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
