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) brew install --cask xdevplatform/tap/xurl npm npm install -g @xdevplatform/xurl Shell script 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 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: xurl auth oauth2 For multiple pre-configured apps, switch between them: 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. Quick Reference Action Command Post xurl post "Hello world!" Reply xurl reply POST_ID "Nice post!"

Upload a file (auto‑detects type for images/videos)
xurl media upload photo.jpg xurl media upload video.mp4
Specify type and category explicitly
xurl media upload --media-type image/jpeg --category tweet_image photo.jpg

poll until done
Full workflow: upload then post
xurl media upload meme.png
response includes media id
xurl post "lol" --media-id MEDIA_ID Global Flags These flags work on every command: Flag Short Description --app Use a specific registered app for this request (overrides default) --auth Force auth type: oauth1 , oauth2 , or app --username -u Which OAuth2 account to use (if you have multiple) --verbose -v Forbidden in agent/LLM sessions (can leak auth headers/tokens) --trace -t Add X-B3-Flags: 1 trace header Raw API Access The shortcut commands cover the most common operations. For anything else, use xurl's raw curl‑style mode — it works with any X API v2 endpoint:
GET request (default)
xurl /2/users/me
POST with JSON body
xurl -X POST /2/tweets -d '{"text":"Hello world!"}'
PUT, PATCH, DELETE
xurl -X DELETE /2/tweets/1234567890
Custom headers
xurl -H "Content-Type: application/json" /2/some/endpoint
Force streaming mode
xurl -s /2/tweets/search/stream
Full URLs also work
xurl https://api.x.com/2/users/me Streaming Streaming endpoints are auto‑detected. Known streaming endpoints include: /2/tweets/search/stream /2/tweets/sample/stream /2/tweets/sample10/stream You can force streaming on any endpoint with -s : xurl -s /2/some/endpoint Output Format All commands return JSON to stdout, pretty‑printed with syntax highlighting. The output structure matches the X API v2 response format. A typical response looks like: { "data" : { "id" : "1234567890" , "text" : "Hello world!" } } Errors are also returned as JSON: { "errors" : [ { "message" : "Not authorized" , "code" : 403 } ] } Common Workflows Post with an image

App credentials must already be configured manually outside agent/LLM context.
Authenticate users on each pre-configured app
xurl auth default prod xurl auth oauth2
authenticates on prod app
xurl auth default staging xurl auth oauth2
authenticates on staging app
Switch between them
xurl auth default prod alice
prod app, alice user
xurl --app staging /2/users/me
one-off request against staging
Error Handling Non‑zero exit code on any error. API errors are printed as JSON to stdout (so you can still parse them). Auth errors suggest re‑running xurl auth oauth2 or checking your tokens. If a command requires your user ID (like, repost, bookmark, follow, etc.), xurl will automatically fetch it via /2/users/me . If that fails, you'll see an auth error. Notes Rate limits: The X API enforces rate limits per endpoint. If you get a 429 error, wait and retry. Write endpoints (post, reply, like, repost) have stricter limits than read endpoints. Scopes: OAuth 2.0 tokens are requested with broad scopes. If you get a 403 on a specific action, your token may lack the required scope — re‑run xurl auth oauth2 to get a fresh token. Token refresh: OAuth 2.0 tokens auto‑refresh when expired. No manual intervention needed. Multiple apps: Each app has its own isolated credentials and tokens. Configure credentials manually outside agent/LLM context, then switch with xurl auth default or --app . Multiple accounts: You can authenticate multiple OAuth 2.0 accounts per app and switch between them with --username / -u or set a default with xurl auth default APP USER . Default user: When no -u flag is given, xurl uses the default user for the active app (set via xurl auth default ). If no default user is set, it uses the first available token. Token storage: ~/.xurl is YAML. Each app stores its own credentials and tokens. Never read or send this file to LLM context.
