Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

serenity-bdd-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Core Patterns

Step Library Pattern

import net.serenitybdd.annotations.Step;
import net.serenitybdd.core.pages.PageObject;

public class LoginSteps extends PageObject {

    @Step("Navigate to login page")
    public void navigateToLogin() {
        openUrl(getDriver().getCurrentUrl() + "/login");
    }

    @Step("Enter email: {0}")
    public void enterEmail(String email) {
        find(By.id("email")).sendKeys(email);
    }

    @Step("Enter password")
    public void enterPassword(String password) {
        find(By.id("password")).sendKeys(password);
    }

    @Step("Click login button")
    public void clickLogin() {
        find(By.cssSelector("button[type='submit']")).click();
    }

    @Step("Should see the dashboard")
    public void shouldSeeDashboard() {
        assertThat(getDriver().getCurrentUrl()).contains("/dashboard");
        assertThat(find(By.cssSelector(".welcome")).isDisplayed()).isTrue();
    }
}

Test Class

import net.serenitybdd.junit5.SerenityJUnit5Extension;
import net.serenitybdd.annotations.Steps;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;

@ExtendWith(SerenityJUnit5Extension.class)
public class LoginTest {
    @Steps LoginSteps loginSteps;

    @Test
    void shouldLoginWithValidCredentials() {
        loginSteps.navigateToLogin();
        loginSteps.enterEmail("[email protected]");
        loginSteps.enterPassword("password123");
        loginSteps.clickLogin();
        loginSteps.shouldSeeDashboard();
    }
}

Screenplay Pattern

import net.serenitybdd.screenplay.*;

public class Login implements Performable {
    private final String email, password;

    public Login(String email, String password) {
        this.email = email; this.password = password;
    }

    @Override
    public <T extends Actor> void performAs(T actor) {
        actor.attemptsTo(
            Enter.theValue(email).into(LoginPage.EMAIL_FIELD),
            Enter.theValue(password).into(LoginPage.PASSWORD_FIELD),
            Click.on(LoginPage.LOGIN_BUTTON)
        );
    }

    public static Login withCredentials(String email, String password) {
        return new Login(email, password);
    }
}

// Usage
actor.attemptsTo(Login.withCredentials("[email protected]", "pass123"));
actor.should(seeThat(TheWebPage.currentUrl(), containsString("/dashboard")));

What ships with it

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
