Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is dalehurley/codewithphp's own configuration. It tells GitHub Copilot how to work on codewithphp 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 codewithphp 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

codewithphp copilot-instructions.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.

Copilot AI Agent Instructions for PHP-From-Scratch

Project Overview

  • Purpose: This repo is a comprehensive, example-driven PHP learning series. It uses VitePress for documentation and organizes code samples by chapter.
  • Structure:
    • docs/ — VitePress content root (site config, landing, series, chapters, code)
    • docs/series/<series>/chapters/ — Numbered markdown chapters
    • docs/series/<series>/code/ — Code samples for each chapter, colocated
    • .github/workflows/ — GitHub Actions for VitePress deploy
    • .cursor/rules/ — Project structure and navigation rules
    • package.json — VitePress scripts (dev/build/preview)

Key Conventions & Patterns

  • Each series is self-contained: All content, code, and navigation for a series lives under its own folder in docs/series/.
  • Code samples: Each chapter has matching code in code/, named by chapter and topic. Exercise solutions are in solutions/ subfolders.
  • Markdown-first: All learning content is authored in markdown, with code blocks and explanations inline.
  • PSR-12/PSR-4: Code samples follow modern PHP standards (see Chapter 16 for details).
  • No framework dependencies unless in framework-specific chapters (e.g., Laravel, Symfony).
  • Composer: Used only in relevant chapters; not required for the whole repo.

Developer Workflows

  • Preview docs locally: 
    npm install
npm run docs:dev
# Visit http://localhost:5173
  • Build for production: 
    npm run docs:build
  • Deploy:
    • GitHub Actions auto-deploys main branch to Pages using .github/workflows/deploy.yml.
  • Test code samples:
    • Run PHP scripts directly: php <filename>.php
    • Some chapters include test scripts or expected output in comments/README.
  • Debugging:
    • Use VS Code with Xdebug (see 00-setup/README.md for setup and troubleshooting).

Integration Points

  • VitePress: All site config in docs/.vitepress/config.ts.
  • GitHub Pages: Deploy via Actions; see .github/workflows/.
  • Composer: Only in chapters that teach dependency management (not global).

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.
