PDF Reader Tool
The PDF Reader Tool allows an Agent to read, interpret, and reason over the entire content of a PDF document that is uploaded during the Agent configuration.
Unlike Knowledge Bases, which split content into chunks for retrieval, PDF Reader preserves the full structure and continuity of a single document, enabling deeper and more contextual reasoning.
🔎 What It Does
With PDF Reader, an Agent can:
Read a pre-configured PDF document
Understand the document as a whole, without fragmentation
Extract insights, summaries, rules, or structured information
Reason across sections, pages, and references consistently
This tool is ideal when a document must be treated as authoritative context, not as searchable snippets.
🧠 How PDF Reader Works
PDF Reader acts as a static cognitive extension of the Agent.
At configuration time:
The Agent creator uploads a PDF file.
The full document is ingested as a single contextual source.
During conversations, the Agent can reason over the entire document whenever needed.
The document remains available to the Agent as long as the tool exists.
The Agent decides to use the PDF Reader based on the tool description, not by user action.
📚 PDF Reader vs Knowledge Base
Use PDF Reader when:
The document must be interpreted as a whole
Cross-section understanding is required
The content represents a single source of truth (e.g., contract, policy, manual)
The document does not need semantic retrieval by fragments
Use Knowledge Base when:
Content must be searchable and modular
Information changes frequently
Multiple documents need to be queried
You want long-term, scalable retrieval
💡 Rule of thumb: PDF Reader is for deep reasoning over one document. Knowledge Base is for searching across many documents.
📄 Common Use Cases
Company policies or internal rulebooks
Legal contracts or compliance documents
Technical manuals or specifications
Institutional PDFs that must be followed strictly
⚙️ Tool Configuration
When creating a PDF Reader Tool, you configure:
Name A clear identifier for the tool Example:
Company Policy PDFDescription Guides the Agent on when to use the document Example:
“Use this tool whenever the user asks about company rules, policies, or internal procedures.”
PDF File The document uploaded during Agent configuration
The description is essential — it determines when the Agent will rely on the PDF.
🧠 Best Practices
Use PDF Reader for documents that must be interpreted in full
Avoid duplicating large documents into the main prompt
Keep the description explicit and scoped
If the document needs frequent updates or search, prefer a Knowledge Base
Combine with Tasks or Follow Ups to act on document-based conclusions
✅ Key Takeaway
The PDF Reader Tool allows an Agent to reason over a single, complete PDF document configured by the Agent creator, without chunking or fragmentation.
It is the best choice when structural integrity, coherence, and full-context understanding are critical — turning a static PDF into a trusted, always-available reference for the Agent.
