Failed to push tag: {stderr}
Error message
Failed to push tag: {stderr} What it means
After creating the tag, `grok plugin tag` runs `git push origin <tag>` and bails with 'Failed to push tag: {stderr}' when the push exits non-zero, surfacing git's stderr. This reports remote publishing failures.

Solutions
- Verify the remote exists: `git remote -v`, and add it if missing (`git remote add origin <url>`)
- Authenticate: run `git fetch origin` to trigger credential setup, or load your SSH key with `ssh-add`
- If the tag already exists remotely, re-run with `--force` (or delete it remotely first)
- Push manually with `git push origin <tag>` to see the full git error
Example fix
// before grok plugin tag . --push # ERROR: Permission to ... denied (publickey) // after ssh-add ~/.ssh/id_ed25519 grok plugin tag . --push

Ok(_) => {}
Err(e) => return Err(e),
} Prevention
- Verify `git remote -v` and push access before releasing
- Keep SSH keys loaded (ssh-agent) or HTTPS credentials fresh
- Run `git ls-remote origin` as a network/auth preflight in release scripts
- Use --force deliberately and only when the remote tag is known-stale
When it happens
Trigger: Running `grok plugin tag --push` where the remote rejects the push: no 'origin' remote, missing auth/credentials, remote already has the tag without --force, or no network.
Common situations: Repo cloned without push access; HTTPS credentials expired or SSH key not loaded (ssh-agent); tag already on remote from another machine; corporate proxy blocking git.
