## What it does

This skill bootstraps a testing suite using the `coder-eval` runner. It inspects the codebase to discover what can be verified, checking for Claude Code skills, MCP server definitions in files like `.mcp.json`, or CLI commands declared in `pyproject.toml` or `package.json`. If the repository already contains evaluation tasks, it reports the current inventory and stops. Existing tasks are never overwritten.

When generating the test setup, the skill creates a single functional task rather than an empty folder. It creates validation criteria, appends needed environment keys such as `ANTHROPIC_API_KEY` to `.env.example`, and confirms `.env` is listed in `.gitignore`. It then runs `coder-eval plan <task-directory>/*.yaml` until the schema validation returns code 0.

Installing the skill does not install the `coder-eval` CLI binary. Without that binary present in your environment, execution halts on the first step.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add UiPath/coder_eval --skill init -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/init/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/init/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add UiPath/coder_eval --skill init -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/init/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add UiPath/coder_eval --skill init -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/init/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install UiPath/coder_eval init
```

2. **Manually: put the files in place**
- File: `.github/skills/init/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add UiPath/coder_eval --skill init -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/UiPath/coder_eval --path plugins/coder-eval/skills/init
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/init/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add UiPath/coder_eval --skill init -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/UiPath/coder_eval/tree/HEAD/plugins/coder-eval/skills/init/SKILL.md

## When to use it
- scan a codebase for testable CLI tools or MCP servers
- scaffold a runnable YAML task for coder-eval
- populate .env.example with required agent keys
- validate task schema definitions using coder-eval plan

## Example prompts
- Set up coder-eval in this repository and create a test for our CLI
- Scan this project for MCP servers and prepare a test task for coder-eval
- Initialize a coder-eval suite to test our custom skills

# Set up coder-eval in this repository

Goal: leave the user with a task directory containing **one real task** they can run
immediately, not an empty scaffold. The task must exercise something this repository
actually ships.

The user's request is: `$ARGUMENTS`

## Step 1 — Check prerequisites

Run `coder-eval --version`. Installing this plugin did not install the CLI, and
every later step needs it.

If it is missing, follow `${CLAUDE_PLUGIN_ROOT}/reference/cli-setup.md`: offer the
install, **ask before running it**, and confirm with `coder-eval --version`
afterwards. Never install unprompted, and do not continue if the user declines.

That reference also covers the other half of the version check — whether this project
pins a coder-eval version, and what to do when the installed one does not match it.

## Step 2 — Check whether this repository is already configured

This skill scaffolds a first suite. Run against a repository that already has one, it
would write a "first task" beside an existing tree and report success — so find out
before writing anything.

Locate the eval tree per `${CLAUDE_PLUGIN_ROOT}/reference/repo-layout.md`. **If the
repository already has tasks, report the inventory and stop**: how many task files and
where, how many run directories, and whether there are experiments. Then point the user
at the skills that act on what exists —

- `/coder-eval:lint-tasks` to review the tasks already there;
- `/coder-eval:analyze` to read a finished run.

Only scaffold if the repository has none, or if the user explicitly asks for more after
seeing the inventory. **Never overwrite an existing task file**, whatever they ask for;
add alongside it.

A repository with tasks but no experiments is **partially** configured, not empty.
Report that as it is and offer the missing piece — do not scaffold a first task as
though there were nothing there.

## Step 3 — Scan for what is testable

Look for these, in priority order, and **report what you found before writing
anything**:

1. **Claude Code skills** — glob `.claude/skills/*/SKILL.md` and `**/skills/*/SKILL.md`.
   Skills are the highest-value thing to evaluate, because whether they trigger is
   invisible until it fails. If you find any, recommend `/coder-eval:check-skill` for
   each of them — that is a purpose-built activation suite, not something to hand-roll
   here.
2. **An MCP server** — an `.mcp.json`, an `mcpServers` key in `package.json` or
   `pyproject.toml`, or a server entry point (a `server.py` / `index.ts` that registers
   tools). Note which tools it exposes.
3. **A CLI entry point** — `[project.scripts]` in `pyproject.toml`, `bin` or `scripts` in
```
