NO_CURRENT_BRANCH

NO_CURRENT_BRANCH

Error message

Could not determine current git branch

What it means

Returned by createTagFromBranchDirect when no targetBranch argument was supplied and the current git branch could not be determined from the repository (e.g. detached HEAD or no commits yet). The function needs a branch name to derive the tag; without one it fails with code NO_CURRENT_BRANCH.

Solutions

1. Pass the branch explicitly in the tool call (e.g. branchName: 'main').
2. Ensure HEAD is on a named branch: 'git checkout -b main' or 'git checkout main'.
3. Make an initial commit so the branch exists: 'git commit --allow-empty -m init'.
4. Verify with 'git -C <projectRoot> branch --show-current' that a branch name is resolvable before invoking the tool.

Example fix

// before
await createTagFromBranchDirect({ projectRoot }); // detached HEAD, no branch arg
// after
await createTagFromBranchDirect({ projectRoot, branchName: currentBranch }); // e.g. 'main'

const { execSync } = require('child_process');
function currentBranch(root) {
  try {
    return execSync('git branch --show-current', { cwd: root }).toString().trim() || null;
  } catch { return null; }
}
const branch = args.branchName || currentBranch(projectRoot);
if (!branch) throw new Error('No current branch; pass branchName explicitly');

function hasBranchName(args) {
  return typeof args.branchName === 'string' && args.branchName.trim().length > 0;
}

const res = await createTagFromBranchDirect(args);
if (!res.success && res.error?.code === 'NO_CURRENT_BRANCH') {
  // fall back to asking the user for a branch, or `git checkout -b main` first
}

When it happens

Trigger: Calling create_tag_from_branch without the branchName/targetBranch parameter on a repo in detached HEAD state ('git checkout <sha>'), on an unborn branch (fresh 'git init' with zero commits), or where the git branch command fails in the target directory.

Common situations: CI checkouts that pin a commit SHA (GitHub Actions checkout of a tag/SHA), freshly initialized repos with no first commit, or forgetting to pass the branch argument from an MCP client that omits optional fields.
