Configure Copilot instructions for repository

[Copilot]

Establishes comprehensive Copilot instruction files to guide AI-assisted development with project-specific conventions and patterns.

Files Added

• .github/copilot-instructions.md - Repository-wide context

  • Tech stack: TypeScript, Express.js, React 18, Vite, Tailwind CSS
  • Project structure and npm workspace organization
  • Build/test commands, coding standards, data model (ERD)

• .github/instructions/API.instructions.md - API-specific patterns

  • YAML frontmatter: applyTo: 'api/**/*.ts'
  • Swagger/OpenAPI JSDoc comment templates
  • RESTful conventions, in-memory storage patterns, Vitest testing standards

• .github/instructions/Frontend.instructions.md - Frontend-specific patterns

  • YAML frontmatter: applyTo: 'frontend/**/*.{ts,tsx}'
  • React functional components with hooks, React Query v3 data fetching
  • Tailwind CSS conventions, TypeScript interface patterns, form handling

Example: API Route Pattern

/**
 * @swagger
 * /api/products:
 *   get:
 *     summary: Returns all products
 *     tags: [Products]
 *     responses:
 *       200:
 *         description: List of all products
 */
router.get('/api/products', (req, res) => { ... });

Instructions reflect actual codebase patterns (Swagger comments, Express routing, React Query usage) to ensure consistent AI-generated code.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• gh.io
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
