Semantic Search & RAG Tool

The RAG Symbol Graph Tool

Query a symbol graph of an indexed repository to find where things are defined and used — so an agent can traverse a codebase by structure, not just text.

The Retrieval Problem

Your answer exists — retrieval just can’t find it

Private knowledge is only useful if an agent can retrieve exactly the right piece and ground its answer in it. Keyword search misses, hosted RAG can’t touch sensitive data, and ungrounded models make things up.

01

Keyword search misses

The right content is phrased differently than the query.

02

Ungrounded answers

Without retrieval, models invent instead of cite.

03

Scale hides signal

The best chunk is buried among thousands of near-matches.

04

Hosted RAG is off-limits

Sensitive knowledge can’t go to a third-party index.

How the RAG Symbol Graph tool works in practice

RAG Symbol Graph is a semantic search & rag tool you assign to a VDF AI agent. It queries a symbol graph of an indexed repository to return definitions, references, and relationships for a symbol. Its hallmarks — Symbols, Definitions, References — let an agent rely on it as a dependable step in a larger task rather than a brittle one-off script.

Under the hood, it builds and traverses a structural graph of the code, so an agent can follow definitions and usages precisely instead of guessing from text matches. It expects repo and symbol as required inputs, so calls are explicit and easy to audit. Every call is scoped to the requesting tenant and written to an audit log, so the capability is safe to run inside a regulated, on-premise environment — the same governance model behind every VDF AI tool.

Teams reach for RAG Symbol Graph when they need to handle definition lookup, impact analysis, and onboarding. It rarely works alone — pair it with RAG Grep, Find References, and Repository MAP to build a complete, governed workflow, then compose those steps into an on-premise VDF AI Network.

Where it pays back

Where RAG Symbol Graph pays back

Definition lookup

Jump to where a function or type is defined.

Impact analysis

Find every reference before changing a symbol.

Onboarding

Trace how a component connects to the rest.

Precise edits

Ground a refactor in the real reference set.

How VDF AI connects it

Assigned to agents, orchestrated as networks

On VDF AI, an industry’s use cases map to agents, and you assign tools like this one to those agents. Compose multiple agents into a governed, on-premise network.

FAQ

Questions about the RAG Symbol Graph tool

What is the RAG Symbol Graph tool?

It queries a symbol graph of an indexed repository to return definitions, references, and relationships for a symbol. Assigned to a VDF AI agent, it runs under role-based policy with full audit logging so the capability is safe to use in production.

What does it return?

The definitions and references for a symbol, with locations, so an agent can navigate by structure.

How does it pair with grep?

Symbol graph gives structural precision; grep gives literal reach. Together they cover both.

What inputs does the RAG Symbol Graph tool need?

It requires repo and symbol, and optionally accepts relation. Each parameter is validated when an agent calls the tool, and the full call is logged for audit.

Which tools pair well with RAG Symbol Graph?

RAG Symbol Graph is commonly assigned alongside RAG Grep, Find References, and Repository MAP. On VDF AI you compose several tools and agents into a single governed, on-premise network.

Does it run on-premise?

Yes. Like every VDF AI tool, it can run on-premise or in your sovereign cloud, scoped per user and audit-logged, so your data never leaves your perimeter.

How do agents use it?

You assign the tool to an agent under a role-based policy; the agent calls it as one step in a task, and several agents and tools can be orchestrated together as a governed VDF AI Network.
