Token cost

What it costs to keep this loaded

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.

Security

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 1mo 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.

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

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.
