Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00023 | $0.03834 |
| Opus 5 | $0.00012 | $0.01917 |
| Sonnet 5 | $0.00005 | $0.00767 |
| Haiku 4.5 | $0.00002 | $0.00383 |
Grade C, and why
xurl scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
`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. This is a copy
81% identical to xurl — 44 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 415 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 posts 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
~/.xurlto LLM context. - Never ask the user to paste credentials/tokens into chat.
- The user must fill
~/.xurlwith secrets manually on their own machine. - 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.
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)
curl -fsSL https://raw.githubusercontent.com/xdevplatform/xurl/main/install.sh | bash
# Homebrew (macOS)
brew install --cask xdevplatform/tap/xurl
# npm
npm install -g @xdevplatform/xurl
# Go
go install github.com/xdevplatform/xurl@latest
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

xurl is a skill published in the GitHub repository nativ3ai/hermes-agent-camel (196 stars, last pushed 4mo ago), licensed MIT. It adds 23 tokens to every session and 3,834 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). It is 81% identical to xurl, differing in 44 lines, and is treated as a copy.
