# xurl — Agent Skill Reference

`xurl` is a CLI tool for the X API. It supports both **shortcut commands** (human/agent‑friendly one‑liners) and **raw curl‑style** access to any v2 endpoint. All commands return JSON to stdout.

---

## Installation

### Homebrew (macOS)

```bash
brew install --cask xdevplatform/tap/xurl
```

### npm

```bash
npm install -g @xdevplatform/xurl
```

### Shell script

```bash
curl -fsSL https://raw.githubusercontent.com/xdevplatform/xurl/main/install.sh | bash
```

Installs to `~/.local/bin`. If it's not in your PATH, the script will tell you what to add.

### Go

```bash
go install github.com/xdevplatform/xurl@latest
```

---

## Prerequisites

This skill requires the `xurl` CLI utility: <https://github.com/xdevplatform/xurl>.

Before using any command you must be authenticated. Run `xurl auth status` to check.

### Secret Safety (Mandatory)

- Never read, print, parse, summarize, upload, or send `~/.xurl` (or copies of it) to the LLM context.
- Never ask the user to paste credentials/tokens into chat.
- The user must fill `~/.xurl` with required secrets manually on their own machine.
- Do not recommend or execute auth commands with inline secrets in agent/LLM sessions.
- Warn that using CLI secret options in agent sessions can leak credentials (prompt/context, logs, shell history).
- Never use `--verbose` / `-v` in agent/LLM sessions; it can expose sensitive headers/tokens in output.
- Sensitive flags that must never be used in agent commands: `--bearer-token`, `--consumer-key`, `--consumer-secret`, `--access-token`, `--token-secret`, `--client-id`, `--client-secret`.
- To verify whether at least one app with credentials is already registered, run: `xurl auth status`.

### Register an app (recommended)

App credential registration must be done manually by the user outside the agent/LLM session.
After credentials are registered, authenticate with:

```bash
xurl auth oauth2
```

For multiple pre-configured apps, switch between them:

```bash
xurl auth default prod-app          # set default app
xurl auth default prod-app alice    # set default app + user
xurl --app dev-app /2/users/me      # one-off override
```

### Other auth methods

Examples with inline secret flags are intentionally omitted. If OAuth1 or app-only auth is needed, the user must run those commands manually outside agent/LLM context.

Tokens are persisted to `~/.xurl` in YAML format. Each app has its own isolated tokens. Do not read this file through the agent/LLM. Once authenticated, every command below will auto‑attach the right `Authorization` header.
