kora-config-hocon

kora-config-hocon is a skill for Claude Code from kora-projects/kora-skills. It costs 48 tokens per session (2,930 once invoked), scanned A, original, Apache-2.0.

A Kora configuration helper that turns values from an `application.conf` file into typed Java or Kotlin settings, including values supplied through environment variables.

In plain words
What is it for?
Use it when defining typed application settings in Kora or investigating errors such as a missing configuration value.
Why use it?
It prevents configuration from being handled as untyped text and helps locate missing configuration values during development.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **Kora sub-skill — obey the [kora-v1 meta rules](../../SKILL.md) on every task:** **R0** ensure `.kora-agent/` docs+examples are cloned · **R1** read this sub-s.

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

kora-config-hocon 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 10d 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.

Kora Config HOCON

Kora sub-skill — obey the kora-v1 meta rules on every task: R0 ensure .kora-agent/ docs+examples are cloned · R1 read this sub-skill before writing code · R2 Kora APIs only — no Spring/Micronaut/Quarkus, no invented annotations or config keys · R3 journal any incorrect Kora usage. Add comments/Javadoc only if asked.

Artifact: ru.tinkoff.kora:config-hocon | Module: HoconConfigModule | Annotations package: ru.tinkoff.kora.config.common.annotation

HOCON is the recommended config format for Kora. The config-hocon module maps application.conf into type-safe interfaces at compile time. Define a config interface, annotate it, and inject it as an ordinary graph dependency through the constructor. There is no field injection and no runtime reflection — the annotation processor generates the extractor.

Quick Start

1. Dependencies (build.gradle)

dependencies {
    koraBom platform("ru.tinkoff.kora:kora-parent:1.2.19")

    // MANDATORY — without the annotation processor nothing is generated
    annotationProcessor "ru.tinkoff.kora:annotation-processors"

    implementation "ru.tinkoff.kora:config-hocon"
    implementation "ru.tinkoff.kora:logging-logback"
}

Kotlin uses ksp "ru.tinkoff.kora:symbol-processors" instead of annotationProcessor. All ru.tinkoff.kora:* artifacts inherit their version from the kora-parent BOM — never version them individually.

2. Enable the module on @KoraApp

package com.example.app;

import ru.tinkoff.kora.application.graph.KoraApplication;
import ru.tinkoff.kora.common.KoraApp;
import ru.tinkoff.kora.config.hocon.HoconConfigModule;
import ru.tinkoff.kora.logging.logback.LogbackModule;

@KoraApp
public interface Application extends
        HoconConfigModule,
        LogbackModule {

    static void main(String[] args) {
        KoraApplication.run(ApplicationGraph::graph);
    }
}

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.
