GIT015

Error

The Signed-off-by trailer doesn't match the expected identity.

Why this matters

The Signed-off-by trailer must match your configured git identity. If your organization enforces signoff policies, a mismatch means the commit won't pass validation.

How to fix

1. Check your git configuration:

   git config user.name
   git config user.email

2. Update if needed:

   git config user.name "Your Name"
   git config user.email "your.email@klaudiu.sh"

3. Confirm the signoff matches:

   # The -s flag uses your configured identity
   git commit -sS -m "message"

Configuration

Specify expected signoff in config.toml:

[validators.git.commit.message]
expected_signoff = "Your Name <your.email@klaudiu.sh>"

Or disable signoff identity checking:

[validators.git.commit.message]
expected_signoff = ""

Hook output
