eval-code-evaluator

eval-code-evaluator is a skill for Claude Code, Codex from ZTE-AICloud/Co-OmniSpec. It costs 66 tokens per session (1,332 once invoked), scanned A, original, MIT.

A code-quality evaluator that uses third-party judging models to score generated code for correctness and usefulness against stated requirements.

In plain words
What is it for?
Use it to assess AI-written code, compare code outputs, and check whether a code change meets a specification.
Why use it?
It turns a subjective code review into structured feedback and makes it easier to compare different generated implementations.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

eval-code-evaluator 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 5d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/evaluate_code.py, scripts/judge_model_metrics_standalone.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.

Judge Model Evaluator Skill

This skill evaluates code generation quality using standardized metrics including ICE Score (Functional Correctness + Usefulness) and Code Judge assessments.

When to Use

  • Evaluating AI-generated code against requirements
  • Assessing code quality in automated workflows
  • Comparing multiple code implementations
  • Getting structured feedback on code changes
  • Validating that code meets specification requirements

Quick Start

  1. Ensure you have API access configured
  2. Provide the requirement description and generated code
  3. Optionally provide reference code for comparison
  4. Get comprehensive evaluation scores

What You Need to Provide

Required Inputs

  1. Requirements/Feature Description - What the code is supposed to do

    • Format: List of change descriptions or natural language requirements
  2. Generated Code - The code to be evaluated

    • Format: String or structured code blocks with file paths

Optional Inputs

  1. Reference Code - Correct/expected implementation (if available)
    • Improves evaluation accuracy
    • Format: List of code answers with file paths and snippets

Evaluation Metrics

ICE Score Components

  • Functional Correctness (0-1): Does the code correctly implement the requirements?
  • Usefulness (0-1): Is the code practical and well-structured?

Code Judge Components

  • Score (0-1): Overall code consistency and quality
  • Inconsistencies: Detailed list of issues found
    • Severity levels: Small, Major, Fatal
  • Inconsistencies Count: Number of issues found

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.
