# TestTau Agent Skill

TestTau gives AI agents disposable email inboxes and webhook capture endpoints for QA, CI, signup, checkout, and integration tests.

Agents can:

- create public disposable inboxes at `<inbox>@mail.testtau.com`;
- wait for email and fetch parsed JSON;
- use private API-key protected inboxes for signed-in users;
- capture HTTP requests at `https://hook.testtau.com/<hookId>`;
- inspect, replay, and assert webhook captures with JSON Schema.

Best-fit workflows:

- signup, magic-link, invite, receipt, and checkout email tests;
- Stripe, Clerk, GitHub, app, and local webhook capture;
- CI gates that require a webhook to arrive or match a JSON Schema;
- AI coding-agent end-to-end tests that need temporary external endpoints.

Canonical hosted skill:

- `https://testtau.com/skills/testtau/SKILL.md`
- `https://testtau.com/skills/testtau/references/api.md`
- `https://testtau.com/llms.txt`

## Install

Copy this folder into an agent's skills directory, or point the agent to the hosted `SKILL.md` URL.

For catalogs that ingest skill packages, use this folder as the package root:

```text
agent-skills/testtau
```

## Quick Start

```bash
INBOX="agent-login-$(date +%s)"
echo "Send mail to $INBOX@mail.testtau.com"
curl -fsS "https://mail.testtau.com/i/$INBOX/api/wait?timeout=15000"
```

```bash
HOOK="agent-hook-$(date +%s)"
curl -fsS -X POST "https://hook.testtau.com/$HOOK" \
  -H "content-type: application/json" \
  -d '{"event":"agent.test"}'
curl -fsS "https://hook.testtau.com/_/$HOOK/api/list"
```

Private mail and private hooks require:

```text
Authorization: Bearer <key>
```
