Not in a git repository, cannot auto-switch tags

Error message

Not in a git repository, cannot auto-switch tags

What it means

autoSwitchTagForBranch integrates tag switching with git branches. Before doing anything it checks isGitRepository(projectRoot); if the working directory is not inside a git repository it logs this warning and returns { switched: false, reason: 'not_git_repo' }. Auto-switching is meaningless without branches, so the operation is safely skipped.

Solutions

1. Run 'git init' in the project root (and make an initial commit) if branch-based tagging is desired.
2. Run the command from within the actual repository root, not a non-repo copy of the files.
3. If you don't need auto-switching, ignore the warning or disable the git workflow option.
4. In CI, ensure the checkout step (e.g. actions/checkout) runs so .git exists before invoking task-master.

Example fix

// before (shell)
npx task-master list  # run in extracted zip, no git
// after
git init && git add -A && git commit -m init
npx task-master list

const { execSync } = require('child_process');
function inGitRepo(root) {
  try { execSync('git rev-parse --is-inside-work-tree', { cwd: root, stdio: 'ignore' }); return true; }
  catch { return false; }
}
if (!inGitRepo(projectRoot)) console.warn('Skipping tag auto-switch: not a git repo');

function isRepoRoot(root) {
  return require('fs').existsSync(require('path').join(root, '.git'));
}

try {
  const r = await autoSwitchTagForBranch(projectRoot, opts);
  if (r.reason === 'not_git_repo') {
    // proceed without tag switching
  }
} catch (e) { /* handle */ }

When it happens

Trigger: Invoking autoSwitchTagForBranch (directly or via task flows that call it, e.g. after task operations with useGitWorkflow enabled) while projectRoot is outside any .git directory, or when git init was never run.

Common situations: Running task-master in a freshly downloaded folder without git init; CI workspaces that copy files without the .git directory; Docker images that omit git metadata; passing a subdirectory or parent path that is not a repo root.
