Error
Git commit is missing required flags (typically -s and -S).
Why this matters
The -s (signoff) flag records Developer Certificate of Origin compliance. The -S (GPG sign) flag cryptographically verifies authorship. Both are required by default.
How to fix
Add the required flags:
git commit -sS -m "message"Or use the long forms:
git commit --signoff --gpg-sign -m "message"Configuration
Set which flags are required in config.toml:
[validators.git.commit]
required_flags = ["-s", "-S"] # Default: both signoff and GPG signRequire only signoff:
[validators.git.commit]
required_flags = ["-s"]Disable flag requirements:
[validators.git.commit]
required_flags = []Hook output
