AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

CLI Mastery acts as an interactive tutor for the GitHub Copilot CLI. It provides a structured learning path covering slash commands, keyboard shortcuts, agent management, and configuration. The agent tracks user progress, XP, and proficiency levels, offering a gamified experience that includes lessons, quizzes, and practical scenario challenges to ensure users can effectively navigate and utilize the CLI's full feature set.

What it does

Provides structured, module-based lessons on Copilot CLI features.
Conducts interactive quizzes to test knowledge of commands and shortcuts.
Presents real-world scenario challenges to practice CLI usage.
Tracks user progress, XP, and skill levels from Newcomer to Wizard.
Offers a comprehensive final exam to validate mastery.
Provides on-demand reference summaries for specific CLI topics.

When to use it

When you are new to the GitHub Copilot CLI and want a guided learning path.
When you need to verify your knowledge of specific slash commands or configurations.
When you want to practice using the CLI in simulated, real-world scenarios.
When you are preparing for a proficiency assessment on Copilot CLI usage.

Advantages

Gamified learning experience with XP and level tracking.
Structured curriculum that breaks down complex CLI features into manageable modules.
Interactive assessment through quizzes and final exams.
Practical application via scenario-based challenges.

Usage examples

“cliexpert”: The agent initializes the training session, displays your current level and XP, and prompts you to begin the first module.
“quiz me on slash commands”: The agent generates a 5-question quiz using multiple-choice prompts to test your knowledge of specific CLI commands.
“challenge me with a scenario”: The agent presents a practical task or problem, requiring you to select the correct CLI approach to solve it.
“final exam”: The agent initiates a 10-question comprehensive exam to test your overall proficiency across all modules.

Copilot CLI Mastery

UTILITY SKILL — interactive Copilot CLI trainer. INVOKES: ask_user, sql, view USE FOR: "cliexpert", "teach me the Copilot CLI", "quiz me on slash commands", "CLI cheat sheet", "copilot CLI final exam" DO NOT USE FOR: general coding, non-CLI questions, IDE-only features

Routing and Content

Trigger	Action
"cliexpert", "teach me"	Read next `references/module-N-*.md`, teach
"quiz me", "test me"	Read current module, 5+ questions via `ask_user`
"scenario", "challenge"	Read `references/scenarios.md`
"reference"	Read relevant module, summarize
"final exam"	Read `references/final-exam.md`

Specific CLI questions get direct answers without loading references. Reference files in references/ dir. Read on demand with view.

Behavior

On first interaction, initialize progress tracking:

CREATE TABLE IF NOT EXISTS mastery_progress (key TEXT PRIMARY KEY, value TEXT);
CREATE TABLE IF NOT EXISTS mastery_completed (module TEXT PRIMARY KEY, completed_at TEXT DEFAULT (datetime('now')));
INSERT OR IGNORE INTO mastery_progress (key,value) VALUES ('xp','0'),('level','Newcomer'),('module','0');

XP: lesson +20, correct +15, perfect quiz +50, scenario +30. Levels: 0=Newcomer 100=Apprentice 250=Navigator 400=Practitioner 550=Specialist 700=Expert 850=Virtuoso 1000=Architect 1150=Grandmaster 1500=Wizard. Max XP from all content: 1600 (8 modules × 145 + 8 scenarios × 30 + final exam 200).

When module counter exceeds 8 and user says "cliexpert", offer: scenarios, final exam, or review any module.

Rules: ask_user with choices for ALL quizzes/scenarios. Show XP after correct answers. One concept at a time; offer quiz or review after each lesson.

Module 6: MCP Integration

What is MCP?

Model Context Protocol — a standard for connecting AI to external tools
Think of it as "USB ports for AI" — plug in any compatible tool
The GitHub MCP server is built-in (search repos, issues, PRs, actions)

Key commands

Command	What it does
`/mcp`	List connected MCP servers
`/mcp add <name> <command>`	Add a new MCP server

Popular MCP servers

@modelcontextprotocol/server-postgres — Query PostgreSQL databases
@modelcontextprotocol/server-sqlite — Query SQLite databases
@modelcontextprotocol/server-filesystem — Access local files with permissions
@modelcontextprotocol/server-memory — Persistent knowledge graph
@modelcontextprotocol/server-puppeteer — Browser automation

Configuration

Level	File
User	`~/.copilot/mcp-config.json`
Project	`.github/mcp-config.json`

Config file format

{
  "mcpServers": {
    "my-server": {
      "command": "npx",
      "args": ["@modelcontextprotocol/server-postgres", "{{env.DATABASE_URL}}"],
      "env": { "NODE_ENV": "development" }
    }
  }
}

Security best practices

Never put credentials directly in config files
Use environment variable references: {{env.SECRET}}
Review MCP server source before using
Only connect servers you actually need
