Go Call Graph Reachability Analysis FAQs

Question 1

What happens if the code doesn't compile?

Accepted Answer

Call graph analysis requires a valid Go workspace. If the project has compilation errors, the skill will report that it cannot build the graph and suggest fixing those errors first.

Question 2

How does this differ from govulncheck?

Accepted Answer

While it serves a similar purpose, this skill provides granular control over the analysis algorithm, produces visual call chains (DOT/SVG), and can analyze specific functions even if govulncheck doesn't have the specific CVE data.

Question 3

Do I need to install external tools to use this skill?

Accepted Answer

Yes, it requires the Go callgraph and digraph utilities. For visual graph generation (SVG), Graphviz is also recommended.

Question 4

What algorithms does this skill use for analysis?

Accepted Answer

It defaults to Variable Type Analysis (VTA) for high precision but supports Rapid Type Analysis (RTA) and Class Hierarchy Analysis (CHA) as faster fallbacks for large codebases.

Question 5

Can it analyze web handlers or test files?

Accepted Answer

Yes, the skill searches for paths from several entry points including main(), init functions, and test entry points to ensure comprehensive reachability checking.
