코드 산출물을 4축(기능/품질/독창성/보안)으로 평가하고 점수 산출. An agent skill from jh941213/my-cc-harness.

Works in 3 steps: Evaluator 에이전트 스폰 → 결과 확인 → CONDITIONAL/FAIL 시
SKILL.md covers 실행 프로세스 and pass@k 멱등성 테스트 (선택)
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Eval is an agent skill from jh941213/my-cc-harness. 코드 산출물을 4축(기능/품질/독창성/보안)으로 평가하고 점수 산출. Evaluator 에이전트를 스폰하여 독립 평가 실행. Triggers on: eval, 평가, 품질 점수, 코드 평가, quality score. NOT for: 코드 작성, 구현, 리뷰.

Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

Example prompts

“/eval”

Requirements

Pre-approved tools (allowed-tools): Read, Bash, Grep, Glob, Agent

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Evaluator 에이전트 스폰
결과 확인
CONDITIONAL/FAIL 시

What it can do on your machine

Read from SKILL.md and the folder at commit e9210e2. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Bash
- Grep
- Glob
- Agent
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 bash).
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

Eval loads about 304 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 97 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~38
When it runs · the whole SKILL.md, loaded when a task matches: ~304

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
```
allowed-tools: Read, Bash, Grep, Glob, Agent
```

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 97 words (~304 tokens).

How do I install Eval in Claude Code?

Run `npx skills add jh941213/my-cc-harness --skill eval -a claude-code`. Or copy the skill folder (skills/eval in jh941213/my-cc-harness) into .claude/skills/eval in your project. Claude Code loads it when a task matches its description.

How do I install Eval in Codex?

Run `npx skills add jh941213/my-cc-harness --skill eval -a codex`. Or copy the skill folder (skills/eval in jh941213/my-cc-harness) into .agents/skills/eval in your project. Codex loads it when a task matches its description.

Can I use Eval in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jh941213/my-cc-harness --skill eval -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/eval, .gemini/skills/eval, .github/skills/eval and .opencode/skills/eval in your project.

What does Eval need to run?

SKILL.md names no scripts, command-line tools or credentials: Eval is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Bash, Grep, Glob, Agent.

Does Eval 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 Eval safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Eval use?

No licence was found for Eval or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Eval use?

About 304 tokens (SKILL.md is roughly 1.2k 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 Eval?

Skills that share tags, products or a category with Eval: Eval (alirezarezvani/claude-skills, 28k stars), Eval (hashgraph-online/awesome-codex-plugins, 1.2k stars), Eval (mikeyobrien/rho, 371 stars) and Eval (ai-analyst-lab/ai-analyst, 304 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Eval?

jh941213 (a GitHub user) maintains it in jh941213/my-cc-harness, which has 126 GitHub stars. The repository holds 66 skills in this directory. The repository was last updated on August 3, 2026.
