Skill metadata
Reference: full SKILL.md
The following is the complete skill definition that Mibyan loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.
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
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
~/.xurlto LLM context. - Never ask the user to paste credentials/tokens into chat.
- The user must fill
~/.xurlwith secrets manually on their own machine. In Docker, this must be the~seen by Mibyan tool subprocesses; see the Docker note below. - Never recommend or execute auth commands with inline secrets in agent sessions.
- Never use
--verbose/-vin agent sessions — it can expose auth headers/tokens. - To verify credentials exist, only use:
xurl auth status.
--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 orgo install are the easiest.
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.- Create or open an app at https://developer.x.com/en/portal/dashboard
-
Set the redirect URI to
http://localhost:8080/callback - Copy the app’s Client ID and Client Secret
-
Register the app locally (user runs this):
-
Authenticate (specify
--appto bind the token to your app):(This opens a browser for the OAuth 2.0 PKCE flow.) If X returns aUsernameNotFounderror or 403 on the post-OAuth/2/users/melookup, pass your handle explicitly (xurl v1.1.0+):This binds the token to your handle and skips the broken/2/users/mecall. -
Set the app as default so all commands use it:
-
Verify:
Common pitfall: If you omit--app my-appfromxurl auth oauth2, the OAuth token is saved to the built-indefaultapp 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-runxurl auth oauth2 --app my-appandxurl auth default my-app.
Docker HOME pitfall: In the official Mibyan Docker layout,/opt/dataismibyan_HOME, but Mibyan tool subprocesses use/opt/data/homeasHOME. That means~/.xurlresolves to/opt/data/home/.xurlfor Mibyan-runxurlcommands, not/opt/data/.xurl. Run the user setup with the same HOME:IfHOME=/opt/data xurl auth statussucceeds butHOME=/opt/data/home xurl auth statusshows no apps or tokens, Mibyan tool calls will not see the credentials.
Quick Reference
Notes:
POST_IDaccepts full URLs too (e.g.https://x.com/user/status/1234567890) — xurl extracts the ID.- Usernames work with or without a leading
@.
Command Details
Posting
Reading & Search
xurl search queries the X index as your authenticated account and returns raw post objects — IDs, authors, full text — so results can be immediately engaged with (reply, like, repost, quote). Use it when you need the actual posts rather than a summarized answer about a topic.
read shortcut. xurl read
expects a post ID or post URL; do not put read before a /2/tweets/...
endpoint. Request the article tweet field and ingest data.article.plain_text
from the JSON response:
Users, Timeline, Mentions
Engagement
Social Graph
Direct Messages
Media Upload
Raw API Access
The shortcuts cover common operations. For anything else, use raw curl-style mode against any X API v2 endpoint:Global Flags
Streaming
Streaming endpoints are auto-detected. Known ones include:/2/tweets/search/stream/2/tweets/sample/stream/2/tweets/sample10/stream
-s.
Output Format

Error Handling
- Non-zero exit code on any error.
- API errors are still printed as JSON to stdout, so you can parse them.
- Auth errors → have the user re-run
xurl auth oauth2outside the agent session. - Commands that need the caller’s user ID (like, repost, bookmark, follow, etc.) will auto-fetch it via
/2/users/me. An auth failure there surfaces as an auth error.
Agent Workflow
- Verify prerequisites:
xurl --helpandxurl auth status. - Before using
xurl search, check intent. Reach for it when the task needs actual post objects, authenticated account context, or leads into an X write action — it is the right surface when the user wants posts they can engage with, not just a summary of a topic. - Check default app has credentials. Parse the
auth statusoutput. The default app is marked with▸. If the default app showsoauth2: (none)but another app has a valid oauth2 user, tell the user to runxurl auth default <that-app>to fix it. This is the most common setup mistake — the user added an app with a custom name but never set it as default, so xurl keeps trying the emptydefaultprofile. - If auth is missing entirely, stop and direct the user to the “One-Time User Setup” section — do NOT attempt to register apps or pass secrets yourself.
- Start with a cheap read (
xurl whoami,xurl user @handle,xurl search ... -n 3) to confirm reachability. - Confirm the target post/user and the user’s intent before any write action (post, reply, like, repost, DM, follow, block, delete).
- Only the
xurlcommand output (or the raw X API response) proves that a state-changing X action happened. Never report a write as done based on any other source — search results, summaries, or prior context. - Use JSON output directly — every response is already structured.
- Never paste
~/.xurlcontents back into the conversation.
Troubleshooting
Notes
- Rate limits: X enforces per-endpoint rate limits. A 429 means wait and retry. Write endpoints (post, reply, like, repost) have tighter limits than reads.
- Scopes: OAuth 2.0 tokens use broad scopes. A 403 on a specific action usually means the token is missing a scope — have the user re-run
xurl auth oauth2. - Token refresh: OAuth 2.0 tokens auto-refresh. Nothing to do.
- Multiple apps: Each app has isolated credentials/tokens. Switch with
xurl auth defaultor--app. - Multiple accounts per app: Select with
-u / --username, or set a default withxurl auth default APP USER. - Token storage:
~/.xurlis YAML. In Docker, use the Mibyan subprocess HOME (/opt/data/homein the official image) so tokens land under/opt/data/home/.xurl. Never read or send this file to LLM context. - Cost: X API access is typically paid for meaningful usage. Many failures are plan/permission problems, not code problems.
