Build Log
Everything built during a single hour with GitHub Copilot CLI — 9 projects, zero boilerplate, all from the terminal.
Technologies Touched
Build Timeline
Learning Paths Page
18:37Researched YouTube in parallel batches for trusted Copilot CLI content, curated 20 videos across 5 progressive learning paths, and built a full page with video cards, thumbnails, and difficulty badges.
- 20 curated videos from 5 trusted channels (GitHub, Microsoft Developer, VS Code, Burke Holland, Gerald Versluis)
- 5 progressive paths: Getting Started → Core Workflows → Advanced → MCP & Extensions → Real-World
- Updated navigation across 4 existing pages
Release Velocity Dashboard
18:44Built an interactive dashboard visualizing the shipping cadence of GitHub Copilot CLI — 90 releases in 161 days. Includes comparison charts against Claude Code, OpenAI Codex CLI, and Cursor.
- Hero stats: 90 releases, 1.8 days average between releases
- Cumulative and monthly release charts via Chart.js
- Side-by-side competitor comparison with sourced changelogs
- Searchable/filterable release table with 90 entries and tags
- 20+ milestone timeline entries
RFP Response Validation
18:06Reviewed a full RFP response document, fact-checked technical claims against official documentation and current product capabilities, and produced a structured review report.
- Validated answers against official Microsoft/GitHub docs
- Generated structured review with accuracy ratings
- Cross-referenced product features with current release state
Hello World
19:10The simplest possible task — created a hello world file in seconds. Showed that Copilot CLI handles the trivial just as naturally as the complex.
Assembly ASCII Art Animation
19:11Built a complete x86-64 NASM assembly program that renders "HECTOR" in animated block letters with a rainbow color sweep — using only raw Windows API syscalls, no C runtime. Created the repo on GitHub with CI.
- ~350 lines of x86-64 NASM assembly
- Rainbow color animation using Windows console API
- Build scripts for local compilation + GitHub Actions CI
- ARM64 compatible via Windows 11 emulation
GitHub Actions Retry Bot
19:16Created an Azure Function App that listens for GitHub webhook events on workflow completions and auto-retries failed runs up to 3 times. Includes webhook signature validation, retry tracking via Azure Table Storage, and full test coverage.
- Azure Functions with TypeScript — webhook endpoint for GitHub events
- Smart retry: validates signatures, tracks attempts in Table Storage, caps at 3
- 38 tests across 4 files — 100% statement/function/line coverage, 87% branch
- Repo created on GitHub with CI workflow
Requirements Synthesis
19:21Took raw, unstructured requirements and synthesized them into a structured, reviewable format — demonstrating Copilot CLI's ability to work with non-code artifacts and business documents.
Expense Tracker (Full-Stack)
19:26Built a complete full-stack expense tracking application from scratch — Express API backend with Prisma ORM, PostgreSQL database with seed data, and a Vite-powered React client. Features CRUD, filtering, budgets, recurring expenses, and CSV export.
- Express.js API with 6 route modules: expenses, categories, budgets, recurring, export, dashboard
- Prisma ORM with PostgreSQL — schema, migrations, and seed data (150+ sample records)
- Dashboard endpoint: monthly totals, MoM change, daily average, top category, budget alerts at ≥80%
- React client with Vite, TypeScript, and full CRUD UI
DevOps Copilot Skill + MCP Server
19:30Created a custom Copilot agent skill backed by an MCP server — designed to orchestrate DevOps workflows from the terminal. Includes plugin manifest, skill definitions, and a TypeScript MCP server with custom tools.
- Plugin manifest (plugin.json) + MCP config (.mcp.json)
- Skill definition with SKILL.md for DevOps orchestration
- TypeScript MCP server package with tool definitions
- Copilot instructions for agent grounding
Northwind Web App (Best Practices)
19:37Scaffolded a Next.js web app following Northwind Traders organization standards — including CI/CD via central reusable workflows, security scanning with CodeQL, Jest testing with coverage enforcement, and proper .gitignore.
- Next.js with TypeScript scaffolded via create-next-app
- Jest configured with 80/75/80/80 coverage thresholds
- CI workflow calling central ci-node.yml reusable workflow
- Security workflow calling central security-scan.yml (CodeQL + dependency review)
Teams Message Mining (WorkIQ)
19:30Used the WorkIQ MCP integration to search Microsoft Teams messages from the Developer Enablement Series, extracting ideas and demand signals around Copilot CLI adoption and use cases.
- Surfaced key themes: multicloud management, migration workflows, custom agents, CLI + Copilot pairing
- Identified customer demand signals for terminal-first workflows
- Queried M365 data live from the terminal via MCP
