# task

Turn a plain-language request into a coder-eval task in YAML. Use it to add evaluation tasks for an agent, tool, CLI, or capability.

## What it does

The skill drafts one or more coder-eval tasks from a request. It keeps the task prompt focused, assigns weighted success criteria, then checks the result with `coder-eval plan`. Before writing files, it checks for the CLI and inspects the repository’s task layout. If the CLI is missing, it asks before offering installation; declining means no task files are written.

It reads local conventions, templates, and nearby tasks, then consults the rubric and criterion field definitions. Available checks include file content, JSON assertions, command execution, and model-based judging. Each task needs at least one criterion that evaluates output content. A project-pinned coder-eval version can differ from the installed CLI, so the version check matters before authoring begins.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add UiPath/coder_eval --skill task -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/task/SKILL.md

## When to use it
- draft a coder-eval task from a natural-language request
- split a request into tasks for several CLI operations
- choose weighted criteria to assess generated output
- follow existing task conventions in a repository

## Example prompts
- Write a coder-eval task that tests whether an agent can list processes with a CLI.
- Create separate evaluation tasks for every registry subcommand.
- Add a task that checks the structure and values of generated JSON.

# Author a coder-eval task

You are writing coder-eval task YAML. The user's request is: `$ARGUMENTS`

If `$ARGUMENTS` is empty, ask what the task should test. Do not invent a subject.

Good tasks use simple prompts: state the goal and the expected output, then let the
agent work out the approach. A single request can produce **several** task files —
"create tasks for all the registry subcommands" means one task per subcommand.

## Step 1 — Understand the request, and check the CLI is there

Run `coder-eval --version` first. Steps 6 and 7 both shell out to it, and finding that out
*after* writing several task files means the user gets a bare `command not found` with
nothing to act on. Installing this plugin did not install the CLI.

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 write any task files 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.

Then establish:

- **What is being tested** — which tool, SDK, CLI, skill, or capability?
- **How many tasks** — one operation, or several?
- **Difficulty** — smoke, basic, or intermediate?
- **Dependencies** — network, packages, starter files, external services?

State any assumptions you make rather than silently picking.

## Step 2 — Look at what already exists

Find the repository's task tree by following
`${CLAUDE_PLUGIN_ROOT}/reference/repo-layout.md`, and say what you resolved. If a task
already covers this ground, say so and offer to modify it instead of adding a
near-duplicate.

**Repo-local convention beats anything bundled with this plugin — where the two
disagree, the repo wins.** Before writing, read what the repository declares about task
authoring: its own contributor or convention documents, a task template if it ships one,
and a few neighbouring tasks. Adopt what you find — naming, tags, thresholds, weights,
where files go — and **say in your report which conventions you adopted**, so the choice
is visible rather than implied.

Two limits on that:

- **A repository that declares nothing** leaves the bundled rubric as the whole answer.
  Precedence is about deferring to a local rule that exists, not about doing nothing
  until one does.
- **Precedence covers style, not soundness.** If a local convention would produce a
  criterion that cannot fail, the rubric's correctness checks still bite — follow the
  convention where you can, say plainly where you did not and why.

## Step 3 — Design the task

**Task ID** — lowercase kebab-case, unique, `<domain>-<action>` (e.g.
`registry-list-processes`).
```
