The index tells an agent what actually moved; the rest costs zero bytes.

By the AIFeed team September 2026 5 min read performance

Most re-crawl bytes buy nothing. The signed index tells the agent what moved.

The index lists every page with a SHA-256 digest, an ETag, token counts, and triage fields. An agent that stored digests from its last visit compares them locally and fetches only the pages whose digests changed.

| Scenario | | Bytes transferred | | vs HTML crawl |

| Full HTML crawl | | 1,205,292 | | baseline |

| Markdown conversion | | 375,630 | | −68.83% |

| Delta consumption | | 51,408 | | −95.73% |

On the repository's 60-page corpus those are the measured numbers. The index itself is small, signed, and cacheable, so the saving survives retries.
