AUTHENTICATION:\n  \
    --mode claude-code: Uses existing Claude Code authentication.\n  \
      OAuth (Pro/Max/Team): works automatically from ~/.claude/.credentials.json\n  \
      API key: set ANTHROPIC_API_KEY for faster startup (optional)\n\n  \
    --mode codex: Uses existing Codex CLI authentication.\n  \
      Device auth: run `codex auth login` first\n  \
      API key: set OPENAI_API_KEY (optional)\n\n  \
NOTES:\n  \
    Each file becomes a separate memory. Names derive from file basenames\n  \
    (kebab-case, lowercase, ASCII). Output is NDJSON: one JSON object per file,\n  \
    followed by a final summary line with counts. Per-file errors are reported\n  \
    inline and processing continues unless --fail-fast is set.")]
