In plain words
What is it for?
Use it when working on the ToolHive Cloud UI repository, especially before editing its TypeScript, React, authentication, API, styling, or testing code.
Why use it?
It gives an assistant the context and rules needed to make changes that fit this particular codebase.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is stacklok/toolhive-cloud-ui's own configuration. It tells Codex and OpenCode how to work on toolhive-cloud-ui itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything toolhive-cloud-ui configures →

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

toolhive-cloud-ui 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.

AI Agent Guidelines - ToolHive Cloud UI

This document provides essential context for AI coding assistants (Claude, GitHub Copilot, Cursor, etc.) working on this codebase.

Quick Start

IMPORTANT: Before making any code changes, read:

  1. This file (AGENTS.md) - Project overview and key patterns
  2. CLAUDE.md - Detailed guidelines for AI assistants
  3. README.md - Setup and deployment instructions
  4. docs/mocks.md - MSW auto-mocker, fixtures, and dev server

Project Summary

ToolHive Cloud UI is a Next.js 16 application for visualizing MCP (Model Context Protocol) servers in user infrastructure.

Technology Stack

Category Technology
Framework Next.js 16 (App Router)
Language TypeScript (strict mode)
UI Library React 19 + React Compiler
Styling Tailwind CSS 4
Components shadcn/ui
Auth Better Auth (OIDC, stateless)
API Client hey-api + React Query
Testing Vitest + Testing Library
Linting Biome
Package Manager pnpm

Core Principles

  1. Server Components First - Use 'use client' only when necessary
  2. Generated API Client - Never write manual fetch logic, use hey-api functions in server actions
  3. Server Actions for API Calls - Client components fetch data via server actions, not direct API calls
  4. Async/Await Only - No .then() promise chains
  5. 🚫 NEVER USE any - STRICTLY FORBIDDEN. Use unknown with type guards or proper types
  6. Stateless Auth - JWT tokens, no server-side sessions

⚠️ Before Suggesting Code

IMPORTANT: This is a Next.js 16 App Router application. Before suggesting any code:

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.
