fusecore

fusecore is a skill for Claude Code, Codex from fusengine/agents. It costs 27 tokens per session (2,498 once invoked), scanned A, original, MIT.

A guide for building FuseCore, a modular-monolith Laravel project. A modular monolith keeps related features in self-contained modules while running as one application, with separate React interfaces and automatic module discovery.

In plain words
What is it for?
Use it to create FuseCore modules, add features, connect isolated React interfaces, and work with module discovery, contracts, and multilingual support.
Why use it?
It explains where FuseCore code belongs and how modules register their routes, services, resources, and translations, reducing the risk of breaking the project’s structure.

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.

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

fusecore 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 today.

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.

FuseCore Modular Architecture

Agent Workflow (MANDATORY)

Before ANY implementation in FuseCore project, spawn 3 agents in parallel, one Agent call each with a name:

  1. fuse-ai-pilot:explore-codebase - Analyze existing modules in /FuseCore/
  2. fuse-ai-pilot:research-expert - Verify Laravel 13 patterns via Context7
  3. fuse-laravel:laravel-expert - Apply Laravel best practices

After implementation, run fuse-ai-pilot:sniper for validation.


Overview

FuseCore is a Modular Monolith architecture for Laravel 13 with React 19 integration.

Component Purpose
Module Self-contained feature (User, Dashboard, Blog)
Auto-Discovery Automatic registration via module.json
Traits HasModule for resource loading
Contracts ModuleInterface, ReactModuleInterface
React Integration Isolated React per module
i18n Multi-language support (FR/EN/DE/IT/ES)

Critical Rules

  1. All code in /FuseCore/{Module}/ - Never in /app/
  2. One module.json per module - Required for discovery
  3. ServiceProvider per module - Use HasModule trait
  4. Files < 100 lines - Split at 90 lines (SOLID)
  5. Interfaces in /App/Contracts/ - Never in components
  6. Migrations in module - /Database/Migrations/
  7. Routes in module - /Routes/api.php

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.
