Brigade is an ecosystem for running crews of AI agents as a personal intelligence system, with local handling of credentials and support for exposing agent crews to the internet for testing. It is for people who want to organize and operate multiple AI agents using their own API keys or existing Claude, ChatGPT, Copilot, Claude Code, or Codex access. The catalogue skills provide workflows for using Brigade and its agent ecosystem.
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 | $0.00057 | $0.03547 |
| Opus 5.5 | $0.00023 | $0.01419 |
| Sonnet 5.5 | $0.00011 | $0.00709 |
| Haiku 4.5 | $0.00006 | $0.00355 |
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.

`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. Copies of this mod

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
~/.xurlwith 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/-vin 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.

xurl is a skill published in the GitHub repository spinabot/brigade (11,357 stars, last pushed 4d ago), licensed MIT. It adds 57 tokens to every session and 3,547 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
