mithril-ui-form: Instructions file for Gemini CLI

GEMINI.md

mithril-ui-form GEMINI.md is an instructions file for Gemini CLI from erikvullings/mithril-ui-form. It costs 707 tokens per session, scanned A, original, MIT.

Project instructions for mithril-ui-form, a Mithril library that builds forms from JSON descriptions. They explain the packages, commands, architecture, validation, accessibility, and pnpm monorepo layout; a monorepo stores several related packages in one repository.

In plain words
What is it for?
Use them when editing form components, validation, conditional fields, plugins, or accessibility behavior, and when working across the project's packages.
Why use it?
They give a coding agent the project context and the commands needed to build, run, and change the library. This reduces time spent discovering conventions and package relationships.

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

mithril-ui-form GEMINI.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 5d 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.

Mithril-UI-Form

This document provides a comprehensive overview of the mithril-ui-form project, its architecture, and development conventions.

Project Overview

mithril-ui-form is a powerful, declarative framework for creating accessible, high-performance forms in Mithril applications. It uses a JSON-based schema to dynamically generate forms with a wide range of features, including:

  • Object-based and array-based forms: Support for editing single objects or collections of objects.
  • Rich component library: Includes a variety of input types, such as text, textarea, select, checkbox, radio, date, time, and file uploads.
  • Conditional logic: Show or hide form fields based on the values of other fields.
  • Validation: Built-in support for required fields and custom validation rules.
  • Plugin system: Extend the library with custom components and functionality.
  • Accessibility: Full compliance with WCAG 2.1 AA standards.

The project is structured as a pnpm monorepo, with the following packages:

Packages

  • mithril-ui-form: The core library that provides the main LayoutForm and ArrayLayoutForm components, as well as all the built-in form components.
  • mithril-ui-form-plugin: This package defines the plugin architecture for mithril-ui-form. It provides the registerPlugin function and the Plugin interface that all plugins must implement.
  • mithril-ui-form-leaflet-plugin: A plugin that adds a Leaflet map component to mithril-ui-form. This is a good example of how to create a custom form component and integrate it into the library.
  • mithril-ui-form-rating-plugin: A plugin that adds a star rating component to mithril-ui-form.
  • example: A webpack-based application that demonstrates how to use the mithril-ui-form library and its plugins. It also serves as a development environment for testing new features.

Building and Running

The project uses pnpm for package management and scripting.

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.
