## What it does

This skill acts as a practical reference for authoring and running automated conversation tests on Botpress ADK bots. It details the TypeScript scenario format from `@botpress/evals`, assertion types, and CLI syntax for `adk evals`.

Tests run directly against an active runtime started with `adk dev`. Because execution targets the real environment rather than mocks, you inspect actual tool calls, extracted parameters, state mutations, and workflow triggers.

Every conversational turn requires either a `user` string or an `event` payload. Declaring `expectSilence: true` by itself is invalid syntax. For post-conversation state checks, assertions belong in the `outcome` section.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add botpress/skills --skill adk-evals -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add botpress/skills --skill adk-evals -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add botpress/skills --skill adk-evals -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install botpress/skills adk-evals
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add botpress/skills --skill adk-evals -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/botpress/skills --path skills/adk-evals
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add botpress/skills --skill adk-evals -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/botpress/skills/tree/HEAD/skills/adk-evals/SKILL.md

## When to use it
- write automated conversation scenarios for ADK bots
- assert tool calls and extracted parameter values
- test state transitions and workflow completion
- execute test suites in CI using `adk evals --format json`

## Example prompts
- Write an eval verifying that createTicket gets called with high priority
- How do I assert that the bot stays silent after a custom event?
- Show me the command to filter and run only regression evals

# ADK Evals Skill

## What are Evals?

Evals are automated conversation tests for ADK agents. Each eval defines a scenario — a sequence of user messages or events — and asserts on what the bot should do: what it says, which tools it calls, how state changes, which workflows run, and more.

Evals run against a live dev bot (`adk dev`), so they test the full stack — not mocks.

## When to Use This Skill

Use this skill when the developer asks about:

- **Writing evals** — file format, assertions, turn types, setup
- **Running evals** — CLI commands, filtering, output interpretation
- **Testing specific primitives** — how to test actions, tools, workflows, conversations, state
- **The testing loop** — write → run → inspect traces → iterate
- **CI integration** — exit codes, `--format json` flag, tagging strategies
- **Eval configuration** — idleTimeout, judgePassThreshold, judgeModel

Or when you are developing an ADK bot and need to write the equivalent of unit/end-to-end tests.

**Trigger questions:**

- "How do I write an eval?"
- "How do I test my workflow?"
- "How do I assert that a tool was called with specific params?"
- "My eval is failing, how do I debug it?"
- "How do I test that the bot stays silent?"
- "How do I run evals in CI?"
- "How do I seed state before an eval?"
- "How do I trigger a workflow in an eval?"

## How to Answer

1. **Writing an eval** → Read `eval-format.md` for structure and assertions
2. **Running evals** → Read `testing-workflow.md` for CLI commands and output
3. **Testing a specific primitive** → Read `test-patterns.md` for the relevant section
4. **Debugging a failure** → Combine `testing-workflow.md` (inspect traces) + `eval-format.md` (check assertion syntax)

## Quick Reference

### Eval file structure

```typescript
import { Eval } from '@botpress/evals'

export default new Eval({
  name: 'greeting',
  type: 'regression',
  tags: ['basic'],

  setup: {
    state: { bot: { welcomeSent: false } },
    workflow: { trigger: 'onboarding', input: { userId: 'test-1' } },
  },

  conversation: [
    {
      user: 'Hi!',
      assert: {
````
