No relevant files to summarize after filtering

Error message

No relevant files to summarize after filtering

What it means

The map-reduce analysis pipeline filters the diff down to files relevant for the commit analysis (via includedFiles over the parsed prompt diff). If no files survive that filter, there is nothing for the map phase to summarize, so runMapReduce throws instead of producing an empty analysis.

Solutions

1. Broaden the file filter patterns in the generation config so the changed files qualify
2. Stage actual source changes, not only lockfiles/generated files
3. Pass the full diff text (verify it contains 'diff --git' file headers)
4. Fall back to direct (non-map-reduce) analysis for filter-only commits

Example fix

// before
const analysis = await runMapReduce({ diff, config });
// after: guard with fallback
const files = includedFiles(parsePromptDiff(diff), config);
const analysis = files.length > 0
  ? await runMapReduce({ diff, config })
  : await generateDirectAnalysis({ diff, config });

const files = includedFiles(parsePromptDiff(diff), config);
if (files.length === 0) {
  // fall back to direct analysis or abort with a clear message
}

function hasMapReduceInput(diff: string, config: Config): boolean {
  return includedFiles(parsePromptDiff(diff), config).length > 0;
}

try {
  return await runMapReduce(input);
} catch (err) {
  if (err instanceof Error && err.message.startsWith("No relevant files")) {
    return generateDirectAnalysis(input); // fallback path
  }
  throw err;
}

When it happens

Trigger: Calling runMapReduce (directly or via analysis/generateAnalysisWithMapReduce) when parsePromptDiff(input.diff) yields files that are all excluded by the config's file filter — e.g. the diff contains only ignored paths (lockfiles, generated files, binary files) or the diff is malformed so no filenames parse out.

Common situations: Commits touching only package-lock.json / bun.lock / generated artifacts, config's relevant-file globs too restrictive, passing a truncated or context-only diff with no file headers, or a custom ConventionalGenerationConfig whose filter excludes everything.
