xurl — X (Twitter) API via the Official CLI

`xurl` is the X developer platform's official CLI for the X API. It supports shortcut commands for common actions AND raw curl-style access to any v2 endpoint. All commands return JSON to stdout.

Use this skill for:

• posting, replying, quoting, deleting posts
• searching for raw posts (actual post JSON with IDs you can engage with) and reading timelines/mentions
• liking, reposting, bookmarking
• following, unfollowing, blocking, muting
• direct messages
• media uploads (images and video)
• raw access to any X API v2 endpoint
• multi-app / multi-account workflows

This skill replaces the older `xitter` skill (which wrapped a third-party Python CLI). `xurl` is maintained by the X developer platform team, supports OAuth 2.0 PKCE with auto-refresh, and covers a substantially larger API surface.

Secret Safety (MANDATORY)

Critical rules when operating inside an agent/LLM session:

• **Never** read, print, parse, summarize, upload, or send `~/.xurl` to LLM context.
• **Never** ask the user to paste credentials/tokens into chat.
• The user must fill `~/.xurl` with secrets manually on their own machine. In Docker, this must be the `~` seen by Hermes tool subprocesses; see the Docker note below.
• **Never** recommend or execute auth commands with inline secrets in agent sessions.
• **Never** use `--verbose` / `-v` in agent sessions — it can expose auth headers/tokens.
• To verify credentials exist, only use: `xurl auth status`.

Forbidden flags in agent commands (they accept inline secrets): `--bearer-token`, `--consumer-key`, `--consumer-secret`, `--access-token`, `--token-secret`, `--client-id`, `--client-secret`

App credential registration and credential rotation must be done by the user manually, outside the agent session. After credentials are registered, the user authenticates with `xurl auth oauth2` — also outside the agent session. Tokens persist to `~/.xurl` in YAML. Each app has isolated tokens. OAuth 2.0 tokens auto-refresh.

Installation

Pick ONE method. On Linux, the shell script or `go install` are the easiest.

# Shell script (installs to ~/.local/bin, no sudo, works on Linux + macOS)
# Prefer a reviewed, version-pinned package; never pipe a remote installer to a shell.

# Homebrew (macOS)
brew install --cask xdevplatform/tap/xurl

# npm
npm install -g @xdevplatform/xurl

# Go
go install "github.com/xdevplatform/xurl@${XURL_VERSION:?Set an exact reviewed release or commit}"

Verify:

xurl --help
xurl auth status

If `xurl` is installed but `auth status` shows no apps or tokens, the user needs to complete auth manually — see the next section.

---

One-Time User Setup (user runs these outside the agent)

These steps must be performed by the user directly, NOT by the agent, because they involve pasting secrets. Direct the user to this block; do not execute it for them.

1. Create or open an app at https://developer.x.com/en/portal/dashboard 2. Set the redirect URI to `http://localhost:8080/callback` 3. Copy the app's Client ID and Client Secret 4. Register the app locally (user runs this):

   xurl auth apps add my-app --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET

5. Authenticate (specify `--app` to bind the token to your app):

   xurl auth oauth2 --app my-app

(This opens a browser for the OAuth 2.0 PKCE flow.)

If X returns a `UsernameNotFound` error or 403 on the post-OAuth `/2/users/me` lookup, pass your handle explicitly (xurl v1.1.0+):

   xurl auth oauth2 --app my-app YOUR_USERNAME

This binds the token to your handle and skips the broken `/2/users/me` call. 6. Set the app as default so all commands use it:

   xurl auth default my-app

7. Verify:

   xurl auth status
   xurl whoami

After this, the agent can use any command below without further setup. OAuth 2.0 tokens auto-refresh.

> **Common pitfall:** If you omit `--app my-app` from `xurl auth oauth2`, the OAuth token is saved to the built-in `default` app profile — which has no client-id or client-secret. Commands will fail with auth errors even though the OAuth flow appeared to succeed. If you hit this, re-run `xurl auth oauth2 --app my-app` and `xurl auth default my-app`.

> **Docker HOME pitfall:** In the official Hermes Docker layout, `/opt/data` is `HERMES_HOME`, but Hermes tool subprocesses use `${HOME}` as `HOME`. That means `~/.xurl` resolves to `${HOME}/.xurl` for Hermes-run `xurl` commands, not `/opt/data/.xurl`. Run the user setup with the same HOME: > ```bash > HOME=${HOME} xurl auth apps add my-app --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET > HOME=${HOME} xurl auth oauth2 --app my-app YOUR_USERNAME > HOME=${HOME} xurl auth default my-app YOUR_USERNAME > HOME=${HOME} xurl auth status > ``` > If `HOME=/opt/data xurl auth status` succeeds but `HOME=${HOME} xurl auth status` shows no apps or tokens, Hermes tool calls will not see the credentials.
