bjoern: Skill for Claude Code

.agents/bjoern-gradle-config/SKILL.md

bjoern-gradle-config is a skill for Claude Code, Codex from Mehtrick/bjoern. It costs 39 tokens per session (3,150 once invoked), scanned A, original, MIT.

Configuration guidance for the Bjoern Gradle plugin, a build tool extension for generating code and documentation. It covers plugin setup, dependencies, tasks, and configuration options.

In plain words
What is it for?
Use it when adding Bjoern to a Gradle project, configuring its generation tasks, or checking the required test libraries and settings.
Why use it?
Gradle build files can be difficult to configure correctly for a specialised plugin. This guidance helps avoid setup errors and missing dependencies.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is Mehtrick/bjoern's own configuration. It tells Claude Code and Codex how to work on bjoern itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything bjoern configures →

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

bjoern-gradle-config scanned grade A with 1 finding 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 11d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Bjoern Gradle Plugin Configuration

Plugin Setup

Finding the Latest Version

IMPORTANT: Always use the latest Bjoern version. Check these sources:

  1. Gradle Plugin Portal: https://plugins.gradle.org/plugin/de.mehtrick.bjoern.gradle-plugin
  2. Maven Central: https://search.maven.org/artifact/de.mehtrick/bjoern-gradle-plugin
  3. GitHub Releases: https://github.com/Mehtrick/bjoern/releases
  4. Project version.config: Check the bjoernversion property in the Bjoern repository

To find the latest version programmatically:

# Check Gradle Plugin Portal
curl -s https://plugins.gradle.org/plugin/de.mehtrick.bjoern.gradle-plugin | grep -o 'version "[^"]*"' | head -1

# Or visit the plugin portal URL directly

Apply the Plugin

Replace LATEST_VERSION with the actual version from the sources above:

plugins {
    id "de.mehtrick.bjoern.gradle-plugin" version "LATEST_VERSION"
}

apply plugin: 'de.mehtrick.bjoern.gradle-plugin'

Example with a specific version (check for updates!):

plugins {
    id "de.mehtrick.bjoern.gradle-plugin" version "1.3.3" // Check for latest!
}

Required Dependencies

dependencies {
    // For JUnit 5 (default)
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.10.2'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.10.2'
    
    // OR for JUnit 4
    testImplementation 'junit:junit:4.13.2'
    
    // Recommended assertion library
    testImplementation 'org.assertj:assertj-core:3.27.7'
}

Gradle Version Requirement

Minimum: Gradle > 7.6.2 (due to Jackson dependency bug) Recommended: Gradle 8.x

Configuration Block

All configuration is done in the bjoern block:

bjoern {
    // Required parameters
    folder = "${projectDir}/src/test/resources"
    pckg = "com.example.tests"
    gendir = "${projectDir}/src/gen/bjoern"
    
    // Optional parameters
    extendedTestClass = "com.example.AbstractBjoernTest"
    docdir = "${projectDir}/src/gen/bjoern/docs"
    template = "/custom-template.ftlh"
    templateFolder = "${projectDir}/src/main/resources/templates"
    docExtension = "adoc"
    junitVersion = "5"
    encoding = "UTF-8"
    specRecursive = true
    gitHistory = false
}

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.
