# gh wrapper — auto-prefixes PR / issue titles with the agent role + appends
# a body footer. Every agent in the template shares one GitHub PAT so plain
# `gh pr list` can't distinguish workspaces; the wrapper reads GIT_AUTHOR_NAME
# (set by the platform provisioner, "Molecule AI <Role>") and rewrites the
# title/body accordingly. Fails open when the env is missing. Anything that
# isn't `gh pr create` or `gh issue create` passes through untouched.
# /usr/local/bin is earlier in PATH than /usr/bin/gh so this shadows the
# real binary without renaming it.
