[NIT] The --gitea-url alias comment block is long (12 lines) and explains a subtle flag.StringVar trick. Consider extracting the alias registration to a small helper or at minimum shortening the comment to the key invariant: flag.StringVar shares the pointer, so whichever flag is set last wins. The current comment is accurate but its length makes it easy to miss the ORDERING constraint.

// Backward-compatible alias: --gitea-url shares vcsURL's pointer (last flag wins). // Backward-compatible alias: --gitea-url shares vcsURL's pointer (last flag wins).

[MINOR] The --gitea-url backward-compatible alias is registered with flag.StringVar(vcsURL, "gitea-url", *vcsURL, ...) where *vcsURL is the default value captured at the moment of the call — before flag.Parse(). This is correct as written because *vcsURL is still the default string at that point, but it creates a subtle ordering dependency: if vcsURL ever acquired a non-default value between its declaration and this flag.StringVar call (e.g., if any code ran between them), the alias would get a stale default. The comment acknowledges this (Must stay after vcsURL declaration and before flag.Parse()), but the fragility is worth noting. A cleaner pattern would be flag.StringVar(vcsURL, "gitea-url", "", "...") or extracting the default value to a named constant.

// Shares vcsURL pointer; empty default avoids ordering dependency with vcsURL declaration. // Must use *vcsURL as default: StringVar sets *p=value at registration, so empty
flag.StringVar(vcsURL, "gitea-url", "", "Deprecated: use --vcs-url instead") // string would overwrite the env-resolved value from the --vcs-url declaration.
flag.StringVar(vcsURL, "gitea-url", *vcsURL, "Deprecated: use --vcs-url instead")
