A guide for building Java and Kotlin services with Kora 1.x, a framework that wires application components together while generating code during the build. It routes work to more specific Kora guides.

Use it when starting or changing a Kora service, configuring its components, diagnosing dependency-wiring problems, or planning a multi-module Gradle project.

It gives Kora-related tasks a consistent starting point and helps select the right guidance for application wiring, configuration, databases, messaging, and other service parts.

kora-v1 — Skill for Claude Code by kora-projects

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/kora-projects/kora-skills

agentmods

npx agentmods add skills/kora-projects/kora-skills/kora-v1

Made for: Claude Code.

Or install kora-v1, the plugin that ships this one along with the rest of its 41 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00268	$0.04533
Opus 5	$0.00134	$0.02266
Sonnet 5	$0.00054	$0.00907
Haiku 4.5	$0.00027	$0.00453

Measured 9d ago against content hash 9e95d54d0a8a, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade C, and why

kora-v1 scanned grade C 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 9d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (install.sh, skills/kora-aop-scheduling-jdk/scripts/setup-jdk.sh, skills/kora-aop-scheduling-quartz/scripts/create-cron-job.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 291 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kora Framework — Meta-skill

Single entry point for all Kora development. This file is routing and rules only — the implementation knowledge lives in the 39 sub-skills listed below.


Framework	Kora 1.x (`ru.tinkoff.kora`) — check the changelog for the current release
Java	17+ supported, 25+ recommended (annotation processors)
Kotlin	1.9+ on JDK 21 (KSP)
Build	Gradle 7+ supported, 9+ recommended (wrapper pins 9.5.1)

This meta-skill is the single entry point for Kora Framework development. It routes to 39 specialized domain skills, each with its own narrow area of expertise.

Read this file first when:

Starting a new Kora microservice project from scratch (Java or Kotlin)
Adding or refactoring @KoraApp application graph with *Module interfaces
Choosing which Kora modules to plug in (HTTP, Database, Kafka, gRPC, SOAP, S3, Telemetry)
Debugging DI container issues ("dependency not found", ambiguous bindings, graph build failures)
Configuring typed config with @ConfigSource and environment variable substitution
Planning a multi-module Gradle project with @KoraSubmodule boundaries

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
