You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: atlassian.go
    path of file: ./repos/gitleaks/cmd/generate/config/rules
    
    the code of the file until where you have to start completion: package rules

import (
	"github.com/zricethezav/gitleaks/v8/cmd/generate/secrets"
	"github.com/zricethezav/gitleaks/v8/config"
)

func Atlassian() *config.Rule {
	// define rule
	r := config.Rule{
		Description: "Detected an Atlassian API token, posin
    
func Atlassian() *config.Rule {
	// define rule
	r := config.Rule{
		Description: "Detected an Atlassian API token, posing a threat to project management and collaboration tool security and data confidentiality.",
		RuleID:      "atlassian-api-token",
		Regex: generateSemiGenericRegex([]string{
			"atlassian", "confluence", "jira"}, alphaNumeric("24"), true),
		Keywords: []string{"atlassian", "confluence", "jira"},
	}

	// validate
	tps := []string{
		generateSampleSecret("atlassian", secrets.NewSecret(alphaNumeric("24"))),
		generateSampleSecret("confluence", secrets.NewSecret(alphaNumeric("24"))),
	}
	return validate(r, tps, nil)
}
