What it does
Eval is an agent skill from jh941213/my-cc-harness. Evaluate code output on 4 axes (functionality/quality/originality/security) with scoring. Spawns an independent Evaluator agent. Triggers on: eval, evaluate, quality score, code evaluation. NOT for: writing code, implementation, review.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Accessibility.
When your agent uses it
- Code evaluation
- Tasks that involve Accessibility
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.
- Spawn the Evaluator agent
- Review results
- On CONDITIONAL/FAIL
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:
ReadBashGrepGlobAgent
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 481 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 128 words of instructions outside code blocks.
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 128 words (~481 tokens).

Questions about Eval
What does Eval do?
Evaluate code output on 4 axes (functionality/quality/originality/security) with scoring. Eval is an agent skill from jh941213/my-cc-harness. Evaluate code output on 4 axes (functionality/quality/originality/security) with scoring.
When should I use Eval?
Eval fits situations like: code evaluation; tasks that involve Accessibility.
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_en/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_en/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?
