Local-first, multi-language code graph explorer, right in the editor. This
extension is a thin UI layer over the GraphSentry CLI
— it never reimplements graph logic itself.
What it does
GraphSentry: Analyze Workspace — parses the current workspace and builds its code graph.
GraphSentry: Show Most Coupled Symbols — fan-in/fan-out ranking, jump straight to a symbol.
GraphSentry: Impact Analysis for Symbol at Cursor — what breaks if you change this?
GraphSentry: Show Call Flow for Symbol at Cursor — Mermaid + ASCII diagram in a side panel.
GraphSentry: Ask a Question About This Codebase — natural-language Q&A (requires a BYOK LLM key — see the main repo's README).
All deterministic commands work with zero LLM key configured. Only "Ask" needs one.
How the binary is managed
On first use, the extension downloads the matching graphsentry CLI binary
for your OS/architecture from the GraphSentry GitHub Releases
and caches it in the extension's storage — no separate install step. If you'd
rather manage your own build (e.g. via go install), set the
graphsentry.binaryPath setting to point at it.
Privacy
Your source code never leaves your machine except for the small subgraph
sent to the LLM you configure yourself when using "Ask" — see the
main repo's privacy section
for exactly what that includes.
