Using and Writing Go Analyses
summary
Shows how to use the Analysis API (golang.org/x/tools/go/analysis) to write an analyzer that finds a real bug: passing a pointer where a value is expected and misusing equality checks. Demonstrates using inspect and type info to compare argument types, reporting precise diagnostics with file/offset, and generating suggested fixes that insert a dereference. Covers building a CLI with singlechecker and wiring the analyzer into gopls/go vet/staticcheck so fixes appear as editor quick fixes.
