## What it does

The skill first asks about coverage, risky areas, and the flows that matter. It then inspects the current branch, finds how to run the app, starts the development server, and writes an explicit test plan before opening the browser.

Browser checks use `agent-browser`. Screenshots and video are stored in `/tmp/alan-captures/`, uploaded to S3, and included in a structured test report. Report creation receives `taskId`, `conversationId`, and `teamId`; the latter is resolved through Alan MCP context and tools.

\`agent-browser` is required, so browser testing stops when the CLI is unavailable. The skill tries `npm install -g agent-browser && agent-browser install`; an installation failure stops the run.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tryalan-ai/alan-skills --skill alan-test-feature -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tryalan-ai/alan-skills --skill alan-test-feature -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tryalan-ai/alan-skills --skill alan-test-feature -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tryalan-ai/alan-skills alan-test-feature
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tryalan-ai/alan-skills --skill alan-test-feature -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tryalan-ai/alan-skills --path skills/alan-test-feature
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tryalan-ai/alan-skills --skill alan-test-feature -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/tryalan-ai/alan-skills/tree/HEAD/skills/alan-test-feature/SKILL.md

## When to use it
- test the current branch in a real browser
- define coverage for a changed feature
- capture screenshots and test video
- send test artifacts to S3
- produce a structured test report

## Example prompts
- Test the current branch with standard coverage and check the feature in a real browser.
- Focus on authenticated flows and invalid input, then save the screenshots and video.
- Start the app, verify the main user flow, and create the test report.

name: alan-test-feature
version: 1.1.1
description: Scope coverage, build a testing strategy, test the feature with agent-browser, capture screenshots/video (always mandatory), upload to S3, and create a structured test report (never skip)
---

## Task: Test Feature & Generate Demo Report

Analyze the current branch's changes, scope the coverage level with the user, build an explicit testing strategy, start the app's dev server, test the feature in a real browser using `agent-browser`, capture screenshots and video (**always — no exceptions**), upload everything to S3, and generate a structured test report (**always — never skip**).

---

## Phase 0: Environment Setup

### 1. Get artifact context IDs

Use the active task context when it is present in the prompt. Otherwise:

- The task ID is available from the `ALAN_TASK_ID` environment variable.
- The conversation ID is available from the `ALAN_SESSION_ID` environment variable.
- Resolve `teamId` with Alan MCP context/tools before creating the report.

When calling `create_test_report`, always pass `taskId`, `conversationId`, and `teamId` explicitly. Do not substitute one ID for another.

### 2. Verify agent-browser is available

`agent-browser` is a **CLI tool** by Vercel Labs (`npm: agent-browser`) — it is NOT a skill or MCP tool. It provides headless browser automation via bash commands (open, click, fill, screenshot, record). In sandboxes it is pre-installed by `runtime-bootstrap.ts`.

```bash
command -v agent-browser >/dev/null 2>&1 && echo "agent-browser: OK" || echo "agent-browser: MISSING"
```

**If missing**, install it:
```bash
npm install -g agent-browser && agent-browser install
```

If installation fails (e.g. no network, no npm), **STOP** and tell the user:
> "agent-browser is not available and could not be installed. Install it manually: `npm install -g agent-browser && agent-browser install`"

Do NOT proceed to Phase 2 without a working `agent-browser` — all browser testing depends on it.

### 3. Create workspace

All captures (screenshots, videos) MUST be written to `/tmp/alan-captures/`.

```bash
mkdir -p /tmp/alan-captures
```

> **CRITICAL — file path rules:**
> - **ONLY** write capture files to `/tmp/alan-captures/`. Never anywhere else.
> - **NEVER** write to `.claude/`, project directories, `reports/`, or any path inside the repo.
> - `.claude/` is a sensitive system directory — writing to it will be blocked and will abort the test run.
> - If you are tempted to create a `reports/` or `screenshots/` folder anywhere other than `/tmp/`, stop and use `/tmp/alan-captures/` instead.

---

## Phase 0.5: Coverage Scoping & Context Gathering (MANDATORY — do before anything else)

**Never skip this phase.** You must understand what the user wants before writing a single test step.

### 1. Ask about coverage level

Use `AskUserQuestion` to ask the user:

```
What level of test coverage do you want for this feature?

- light       — Happy path only. Quick smoke test to verify the main flow works.
