.github/copilot-instructions.md

my-github-202X copilot-instructions.md is an instructions file for GitHub Copilot from DevXDojo/my-github-202X. It costs 2,481 tokens per session, scanned A, original, MIT.

A project-specific instruction file for GitHub Copilot describing a Python Flask web application, its folders, services, databases, authentication, APIs, and frontend. GitHub Copilot uses such instructions to tailor coding suggestions to a repository.

In plain words
What is it for?
Use it to guide Copilot when working on the application's Flask backend, SQLite and SQLAlchemy data layer, GitHub authentication and APIs, or its templates and browser code.
Why use it?
It gives the coding assistant shared information about the project's structure and technology choices instead of making it infer them from each task. This can help suggestions fit the existing backend and frontend.

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

my-github-202X copilot-instructions.md scanned grade A with 1 finding 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 yesterday.

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.

GitHub Copilot Instructions for My GitHub 2025

Project Overview

My GitHub 2025 is a web application that generates beautiful statistics and visualizations of user activities on GitHub for any given year (2008-2025). The application uses Flask (Python 3.12+), GitHub OAuth for authentication, and GitHub's GraphQL/REST APIs to fetch and analyze user activity data.

Project Structure

/config       - Configuration files (app settings, constants)
/models       - SQLAlchemy database models
/routes       - Flask blueprints (auth, main, api)
/services     - Business logic (GitHub API, data processing, database)
/utils        - Helper functions (context builders, error handlers, logging)
/templates    - Jinja2 HTML templates
/static       - Static assets (CSS, JavaScript, images)

Technology Stack

Backend

  • Framework: Flask (Python 3.12+)
  • Database: SQLAlchemy with SQLite
  • Authentication: GitHub OAuth 2.0
  • APIs: GitHub REST API and GraphQL API
  • HTTP Client: requests library with tenacity for retries
  • Time Handling: pytz for timezone support
  • Environment: python-dotenv for configuration

Frontend

  • Templating: Jinja2
  • JavaScript: Vanilla JS
  • Charts: Chart.js
  • Styling: CSS (no framework)

Development Commands

# Run the application
python main.py

# Run with specific environment
export FLASK_ENV=development
python app.py

# Lint code (using pylint)
pylint app.py routes/ services/ utils/ models/ config/

# Format code (if using black)
black .

# Type checking (if using mypy)
mypy .

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.
