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 A, and why

jido_managed_agents AGENTS.md scanned grade A with 0 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This is a web application written using the Phoenix web framework.

Project guidelines

  • Use mix precommit alias when you are done with all changes and fix any pending issues
  • Use the already included and available :req (Req) library for HTTP requests, avoid :httpoison, :tesla, and :httpc. Req is included by default and is the preferred HTTP client for Phoenix apps

Phoenix v1.8 guidelines

  • Always begin your LiveView templates with <Layouts.app flash={@flash} ...> which wraps all inner content
  • The MyAppWeb.Layouts module is aliased in the my_app_web.ex file, so you can use it without needing to alias it again
  • Anytime you run into errors with no current_scope assign:
    • You failed to follow the Authenticated Routes guidelines, or you failed to pass current_scope to <Layouts.app>
    • Always fix the current_scope error by moving your routes to the proper live_session and ensure you pass current_scope as needed
  • Phoenix v1.8 moved the <.flash_group> component to the Layouts module. You are forbidden from calling <.flash_group> outside of the layouts.ex module
  • Out of the box, core_components.ex imports an <.icon name="hero-x-mark" class="w-5 h-5"/> component for hero icons. Always use the <.icon> component for icons, never use Heroicons modules or similar
  • Always use the imported <.input> component for form inputs from core_components.ex when available. <.input> is imported and using it will save steps and prevent errors
  • If you override the default input classes (<.input class="myclass px-2 py-1 rounded-lg">)) class with your own values, no default classes are inherited, so your custom classes must fully style the input

JS and CSS guidelines

  • Use Tailwind CSS classes and custom CSS rules to create polished, responsive, and visually stunning interfaces.

  • Tailwindcss v4 no longer needs a tailwind.config.js and uses a new import syntax in app.css:

    @import "tailwindcss" source(none);
    @source "../css";
    @source "../js";
    @source "../../lib/my_app_web";

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.
