## What it is
Surya is a command-line utility for inspecting Solidity smart contract systems, providing structural summaries, inheritance information, and function call graphs in visual (DOT/graphviz) or text output. It is developed by ConsenSys Diligence and commonly used via the VSCode Solidity Auditor extension.

## Use cases
- generate a call graph for solidity contracts
- visualize smart contract inheritance structure
- audit solidity code manually
- list functions and modifiers in a solidity contract
- explore contract structure before a security review

## When to choose
- you need quick structural insight into Solidity contracts during manual audits
- you want DOT/graphviz call graphs of contract interactions
- you use the VSCode Solidity Auditor extension and want the underlying engine

## When to avoid
- you need automated vulnerability detection rather than manual inspection aids
- you work with languages other than Solidity
- you need a full static analysis or formal verification suite

## Facets
- artifact type: cli-tool
- maturity: active
- function: developer-tools, parser, static-site-generator, data-visualization
- domain: developer-tools, security, blockchain
- platform: cli, cross-platform
- tags: solidity, smart-contracts, static-analysis, call-graph, ethereum, code-inspection, graphviz, nodejs
