코딩 실습 과제(Code Kata)를 체계적으로 설계하는 전문 스킬. An agent skill from revfactory/harness-100.

  • SKILL.md covers 적용 대상 에이전트, 과제 난이도 체계, 과제 템플릿 and 개념별 필수 과제 맵, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Code Kata Generator is an agent skill from revfactory/harness-100. 코딩 실습 과제(Code Kata)를 체계적으로 설계하는 전문 스킬. exercise-creator 에이전트가 난이도별, 개념별 코딩 과제를 출제하고 테스트케이스와 모범 답안을 생성할 때 활용한다. '코딩 과제', '알고리즘 문제', '실습 문제', 'kata', '코딩 테스트', '프로그래밍 연습' 등의 맥락에서 자동 적용한다. 단, 온라인 저지(LeetCode, 백준) 시스템 연동이나 자동 채점 인프라 구축은 이 스킬의 범위가 아니다.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is Apache-2.0.

Example prompts

  • “/code-kata-generator”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Code Kata Generator loads about 663 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 287 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~663

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

코딩 실습 과제(Code Kata)를 체계적으로 설계하는 전문 스킬. exercise-creator 에이전트가 난이도별, 개념별 코딩 과제를 출제하고 테스트케이스와 모범 답안을 생성할 때 활용한다. '코딩 과제', '알고리즘 문제', '실습 문제', 'kata', '코딩 테스트', '프로그래밍 연습' 등의 맥락에서 자동 적용한다. 단, 온라인 저지(LeetCode, 백준) 시스템 연동이나 자동 채점 인프라 구축은 이 스킬의 범위가 아니다.

To copy it by hand, put the folder in .cursor/skills/code-kata-generator, .gemini/skills/code-kata-generator, .github/skills/code-kata-generator and .opencode/skills/code-kata-generator in your project.

What does Code Kata Generator need to run?

SKILL.md names no scripts, command-line tools or credentials: Code Kata Generator is instructions for the agent only.

Does Code Kata Generator access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Code Kata Generator safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Code Kata Generator use?

Code Kata Generator is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Code Kata Generator use?

About 663 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Code Kata Generator?

Skills that share tags, products or a category with Code Kata Generator: Generate (alirezarezvani/claude-skills, 28k stars), Fal Generate (nexu-io/open-design, 100k stars), Video Generation (bytedance/deer-flow, 83k stars) and Image Generation (onyx-dot-app/onyx, 32k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Code Kata Generator?

revfactory (a GitHub user) maintains it in revfactory/harness-100, which has 1,290 GitHub stars. The repository holds 464 skills in this directory. The repository was last updated on March 22, 2026.
