Error message

No staged changes to analyze

What it means

generateGitCommit requires staged changes to analyze. If nothing is staged it first attempts to stage all changes (when options.stageIfEmpty !== false); if the index is still empty after that, it throws because there is no diff to base a commit message on. This is the first of two staged-content checks (this one checks the file list).

Solutions

1. Stage changes first: git add <files> (or run the generator before committing everything)
2. Check git status — if the tree is clean there is nothing to commit
3. Verify ignore rules aren't hiding your changes (.gitignore matching new files)
4. Don't pass stageIfEmpty:false unless you guarantee a pre-populated index

Example fix

// before: throws when nothing staged
const msg = await generateGitCommit({ cwd, repo });
// after: pre-check
diff --no-index /dev/null /dev/null; git status --porcelain
git add -A
const msg = await generateGitCommit({ cwd, repo });

const staged = await repo.changedFiles({ cached: true });
if (staged.length === 0) {
  await repo.stageFiles([]); // stage all, then re-check
}

try {
  const msg = await generateGitCommit(options);
} catch (err) {
  if (err instanceof Error && err.message === "No staged changes to analyze") {
    // inform user: nothing to commit
  }
  throw err;
}

When it happens

Trigger: Calling generateGitCommit (via generated or runLegacyCommitCommand) in a repo where the index is empty AND staging-all yields nothing — i.e. a clean working tree, or all changes are untracked-but-ignored/unchanged, or stageIfEmpty is disabled with nothing pre-staged.

Common situations: Running the commit generator twice (second run: everything already committed), committing in a repo with only untracked files when stageFiles doesn't include untracked paths, or stageIfEmpty:false with a forgotten 'git add'.
