Large Disclosure Document Handling

Some disclosure reports (annual reports, quarterly reports, etc.) are large XML documents of several MB. Processing such documents all at once can exceed AI response limits or cause errors.

How does it work?

The processing method changes automatically depending on document size.

  • Small documents (under 1MB): Returns the entire document immediately.
  • Large documents (1MB or more): Returns a Table of Contents (TOC) instead of the full document. Claude reads the TOC and automatically selects and fetches the sections relevant to your question.

User Guide

No manual action required. Claude handles large documents automatically.

When a document is large, Claude automatically:

  1. Checks the document's table of contents.
  2. Selects and fetches the sections relevant to your question.
  3. After answering, lists the remaining sections โ€” so you can request any other section you're curious about.

Examples:

  • "Show me the revenue overview from the annual report" โ†’ Claude auto-selects the revenue-related section
  • "Also fetch section 3 from the TOC you just showed" โ†’ You can request a specific section directly

๐Ÿ’ก Break Complex Questions into Steps

If you can't get the answer you want in one shot, try breaking your question into smaller steps for more accurate results.

For example, instead of "Show me the foreign investor allocation details from Inventera's securities registration statement", try:

  1. "Get the corp_code for Inventera"
  2. "Search for securities issuance disclosures for that company"
  3. "Fetch the document content for that disclosure"
  4. "Find the foreign investor allocation table"

This way, you can verify each step's output and guide Claude toward the exact information you need.
