Radius Spec Kit Prompt Agent

[brooke-hamilton]

Summary

Adds a new Copilot Chat agent (radius-spec-kit-prompt-agent) that helps contributors translate feature ideas into well-structured Spec Kit prompts. The agent acts as an expert Radius system architect, researching the codebase across all five Radius repositories and generating context-rich prompts for the /speckit.specify and /speckit.plan workflows.

What the agent does

• Analyzes scope — Determines whether a proposed change affects CLI, APIs, resource types, recipes, or multiple components
• Researches existing patterns — Searches the codebase for related functionality and surfaces relevant code paths, APIs, and design documents
• Validates architectural alignment — Checks proposals against the project constitution and established conventions
• Generates ready-to-use prompts — Outputs a markdown document in .copilot-tracking/ containing research notes and a copy-paste prompt for Spec Kit

Files changed

File	Description
.github/agents/radius.speckit.prompt.agent.md	Agent definition with expertise areas, responsibilities, key directory references, workflow guidance, and example interactions
.github/prompts/radius.speckit.prompt.prompt.md	Prompt metadata that wires the agent into Copilot Chat
.gitignore	Ignores .copilot-tracking/ so research artifacts remain local

Usage

Open the design-notes.code-workspace file to load all five Radius repositories, then invoke the agent via Copilot Chat. Describe the feature or change you want to propose, and the agent will produce a structured prompt document ready for /speckit.specify.
