Public API Detection

Go uses capitalization as the visibility mechanism. A symbol is public (exported) if:

1. Its name starts with an uppercase letter
2. It is defined at package level (not inside a function)

Pattern	Public?
func ProcessData(	Yes (uppercase P)
func processData(	No (lowercase p)
type Config struct	Yes
type config struct	No
var MaxRetries =	Yes
const DefaultTimeout =	Yes

Symbol Types to Document

Type	Detection	Documentation Expected
Functions	func Name( at package level	Godoc comment starting with function name
Methods	func (r *Receiver) Name(	Godoc comment starting with method name
Types	type Name struct/interface	Godoc comment starting with type name
Constants	const Name = (exported)	Godoc comment or inline comment
Variables	var Name = (exported)	Godoc comment
Package	package name	Package comment in doc.go or any file

Godoc Format

Go documentation comments must:

1. Start with the symbol name
2. Be a complete sentence
3. Appear directly above the declaration (no blank line between)

// ProcessData reads input from r and returns processed results.
// It returns an error if the input is malformed.
func ProcessData(r io.Reader) ([]Result, error) {

Package Documentation

// Package auth provides user authentication and session management.
//
// It supports OAuth2, JWT, and API key authentication methods.
package auth

Prefer doc.go for package-level documentation.

Documentation Completeness Check

A Go symbol is fully documented when:

1. Has a comment directly above it (no blank line gap)
2. Comment starts with the symbol's name
3. Comment is a complete sentence (ends with period)
4. For functions: parameters and return values are described in the prose

Special Cases

• internal/ packages: exclude from public API coverage (they are internal)
• _test.go files: exclude (test code)
• generated files (containing // Code generated): exclude
• Interface methods: each method should have a comment

File Patterns

Source files: **/*.go Exclude: vendor/, *_test.go, files with // Code generated header
