Document Q&A (Auto)
Automatic detection
You can mention @Hana and ask about attached or linked documents. If intent is clear, Hana automatically routes to document Q&A flows.
What it does
Hana answers questions using document context from files shared in chat or from enabled memory sources. This includes summaries, comparisons, key-point extraction, and risk/decision analysis.
When to use
Use this when you need fast answers from docs, PDFs, or notes without manually reading the full content. Use Memory tools when you want to persist durable information; use Document Q&A when you want analysis of specific documents now.
Supported operations/arguments
| Operation | Invocation pattern | Supported arguments |

Invocation examples

Troubleshooting
- Weak answer quality: ask with explicit scope (
attached PDF,linked doc above) and output format. - Missing document context: ensure the file/link is accessible in the same thread and retry.
- Too broad output: add constraints (
top 5,only risks,this section only).
Permissions/limits
- Document analysis depends on file accessibility and connector permissions.
- If a document is not accessible to Hana, content cannot be retrieved for Q&A.
- For memory-backed retrieval behavior, see memory module docs below.
