Commit Signature

When Arcana makes a git commit on your behalf, it appends a signature trailer to credit the agent. This is configurable — you can choose minimal, branded, or no signature.

Signature Modes

Minimal (Default)

Appends a standard Co-authored-by trailer:

Fix authentication bug

Co-authored-by: arcana 

GitHub/GitLab render this as a co-author avatar. Professional, short, unmistakably Arcana.

Branded

Appends a body line plus the co-author trailer:

Fix authentication bug

⚡ Generated with arcana · the AI coding agent

Co-authored-by: arcana 

More visible attribution. The branded line appears in the commit body.

Disabled

No signature is appended. Commits look entirely manual.

Configuration

Set the signature mode in arcana.json:

{
  "git": {
    "commit_signature": "minimal"
  }
}

When Commits Happen

Arcana commits on your behalf in these scenarios:

• GitHub agent — When the agent creates commits via the GitHub integration
• Skill-driven commits — Skills that modify files and commit changes
• Future: arcana commit — A dedicated commit subcommand (planned)

Duplicate Prevention

Arcana checks for existing Co-authored-by trailers before appending. If the commit message already contains a trailer matching the signature identity, it won't be duplicated.
