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.

This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.

Build agentic applications with GitHub Copilot SDK. Use when embedding AI agents in apps, creating custom tools, implementing streaming responses, managing sessions, connecting to MCP servers, or creating custom agents. Triggers on Copilot SDK, GitHub SDK, agentic app, embed Copilot, programmable agent, MCP server, custom agent.

Coding Agent Session Search - unified CLI/TUI to index and search local coding agent history from Claude Code, Codex, Gemini, Cursor, Aider, ChatGPT, Pi-Agent, Factory, and more. Purpose-built for AI agent consumption with robot mode.

Destructive Command Guard - High-performance Rust hook for Claude Code that blocks dangerous commands before execution. SIMD-accelerated, modular pack system, whitelist-first architecture. Essential safety layer for agent workflows.

Makepad UI development skills for Rust apps: setup, patterns, shaders, packaging, and troubleshooting.

Secure environment variable management ensuring secrets are never exposed in Claude sessions, terminals, logs, or git commits

This skill should be used when the user wants to "package an MCP server", "bundle an MCP", "make an MCPB", "ship a local MCP server", "distribute a local MCP", discusses ".mcpb files", mentions bundling a Node or Python runtime with their MCP server, or needs an MCP server that interacts with the local filesystem, desktop apps, or OS and must be installable without the user having Node/Python set up.

How to use it

Copy the folder

Take github/cli-mastery from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
