kora-openapi-generator-server

kora-openapi-generator-server is a skill for Claude Code from kora-projects/kora-skills. It costs 63 tokens per session (3,237 once invoked), scanned A, original, Apache-2.0.

A generator that creates a Kora HTTP server from an OpenAPI 3.x specification. OpenAPI is a machine-readable description of an HTTP API, including its routes, inputs, outputs, and errors.

In plain words
What is it for?
Use it for contract-first server development: generate controllers, models, and response types, then implement the generated API delegate that contains the application’s behavior.
Why use it?
It keeps the server’s routes and data structures tied to the API contract and avoids hand-writing controllers or editing generated files.

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-openapi-generator-server 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate_openapi.py), 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.

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 OpenAPI Generator — HTTP Server

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.

Generate a type-safe Kora HTTP server from an OpenAPI 3.x contract. The kora generator emits the transport layer (controller, response wrappers, models); you implement one generated *ApiDelegate interface with @Component and return the generated sealed *ApiResponses records. The generated controller registers routes automatically — never write @HttpController/@HttpRoute by hand for a generated API, and never edit files under build/generated/.

All Kora artifacts inherit their version from the kora-parent BOM (ru.tinkoff.kora:kora-parent, e.g. 1.2.19 in the example apps) — never pin a version on an individual ru.tinkoff.kora:* dependency. The OpenAPI plugin org.openapi.generator is pinned to 7.14.0; other versions are not guaranteed to be code-compatible.

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.
