Master FinFocus Plugin Development with AI Agent Skills

Master FinFocus Plugin Development with AI Agent Skills

This skill provides developers with a comprehensive guide to building FinFocus cost plugins using the pluginsdk and gRPC protocol. It supports processes such as creating new plugins, implementing CostSourceService methods, setting up plugin scaffolding, debugging communication, and understanding the plugin lifecycle.

What this skill does

• Assists in the creation of Go modules with the necessary finfocus-spec dependencies.
• Guides embedding of the pluginsdk.BasePlugin for common functionality.
• Provides step-by-step instructions to implement required gRPC methods and build binaries.
• Aids installation of the plugin to the appropriate finfocus directory structure.
• Details plugin architecture, including communication with finfocus-core via gRPC and the use of protocol buffers.
• Explains the two launcher types for plugins: ProcessLauncher (TCP) and StdioLauncher (stdin/stdout).

Who it is for

This skill is designed for software developers and technical teams engaged in developing AI-based coding agent integrations using tools such as Claude Code, Cursor, and Codex. It is especially useful for those involved in financial software development and plugin architecture.

Use cases

• Creation of new cost calculation plugins for financial applications.
• Implementation of advanced cost projection features in AI agents.
• Simplified plugin lifecycle management within a financial context.
• Efficient debugging and communication troubleshooting for plugin development.

Technical details

• Integrates with Claude Code, Cursor, and Codex through set AI agent capabilities.
• Utilizes pluginsdk and gRPC protocol from the finfocus-spec.
• Employs protocol buffers for seamless plugin communication.
• Facilitates the development environment setup for finfocus-core interaction through Go modules.
