It requires no installation beyond cloning this repo and having GitHub Copilot access. ### Setup (5 minutes) 1. Clone this repository: ```bash git clone https://github.com/timothywarner-org/ab900.git cd ab900 ``` 2. Open the folder in VS Code: ```bash code . ``` 3. When prompted, install the recommended extensions (GitHub Copilot + GitHub Copilot Chat). 4. VS Code will prompt for a **Context7 API key** the first time a cert buddy command runs. Get a free key at https://context7.com and paste it when prompted. This enables version-specific M365 admin PowerShell and Graph API syntax lookups. 5. Open GitHub Copilot Chat (`Ctrl+Alt+I` / `Cmd+Alt+I`). ### Two Ways to Interact **Option A -- Slash commands (guided input form):** ``` /ab900-practice-questions /ab900-scenario-walkthrough /ab900-study-planner ``` These open a guided form that collects inputs (domain, difficulty, confidence ratings, etc.) before generating content. **Option B -- Direct agent mention (free-form):** ``` @ab900-cert-buddy-agent Give me a Domain 2 question about DSPM for AI at Apply level, medium difficulty. @ab900-cert-buddy-agent Walk me through approving an agent submission in the M365 admin center. @ab900-cert-buddy-agent Build me a study plan. I am weak on Domain 2 and moderate on the others. ``` --- ## Cert Buddy Features ### Practice Questions Questions use a **two-phase interactive delivery** that mirrors the real exam experience. **Phase 1** -- The agent presents a workplace scenario and four answer choices (A-D), then stops and waits for your reply. **Phase 2** -- After you answer, the agent reveals the correct answer, a 2-sentence rationale for every choice, and Microsoft Learn references. Special commands during Phase 1: | Command | Effect | |---------|--------| | `hint` | Eliminates one distractor | | `skip` | Reveals the answer and moves to rationale | | A / B / C / D | Your answer -- triggers Phase 2 | After a set of questions the agent reports score, percent correct, and domains to review. ### Scenario Walkthroughs Walkthroughs simulate the admin center experience without requiring a live tenant. Each walkthrough: - Sets a realistic admin scenario (for example: "Contoso needs to see what sensitive data Copilot has been accessing") - Walks through 5-10 numbered steps with exact portal URL, navigation path, and correct setting - Flags the AB-900 exam objective each step covers - Notes the most common wrong answers (wrong portal, wrong nav path, wrong role) Available scenario types: - Copilot licensing and pay-as-you-go billing configuration - Agent approval workflow (M365 admin center + Power Platform admin center) - DSPM for AI dashboard review - SharePoint oversharing identification and remediation - Sensitivity label creation and policy assignment - DLP policy review and alert response - PIM role activation and Conditional Access policy review ### Study Planner 1. The agent presents the three AB-900 domains with exam weights. 2. You rate your confidence in each: Strong / Moderate / Weak / Unknown. 3. The agent generates a prioritized study plan -- weakest first, Domain 2 flagged as highest weight. 4. Each domain entry includes estimated study hours, 2-3 Microsoft Learn module links, and key objectives. 5. The agent offers to start generating practice questions on your first priority domain. --- ## Repository Structure ``` ab900/ ├── .github/ │ ├── agents/ │ │ └── ab900-cert-buddy-agent.agent.md # Main Copilot agent │ ├── skills/ │ │ ├── ab900-item-creator/SKILL.md # Practice question generation │ │ ├── ab900-scenario-walkthrough/SKILL.md # Admin scenario walkthroughs │ │ └── ab900-study-planner/SKILL.md # Personalized study plans │ ├── prompts/ │ │ ├── ab900-practice-questions.prompt.md # /ab900-practice-questions command │ │ ├── ab900-scenario-walkthrough.prompt.md # /ab900-scenario-walkthrough command │ │ └── ab900-study-planner.prompt.md # /ab900-study-planner command │ ├── copilot-instructions.md # Workspace Copilot grounding rules │ └── workflows/ │ └── validate.yml # CI: terminology + link validation ├── .vscode/ │ ├── mcp.json # MCP server config (3 servers, auto-loads) │ ├── extensions.json # Recommended extensions │ └── settings.json # Workspace settings ├── references/ │ ├── ab900-objectives.md # Official exam objectives (all 3 domains) │ ├── fictional-companies.md # Microsoft fictional companies for scenarios │ └── style-guide.md # Microsoft Writing Style Guide extract ├── course-plan.md # Live session plan (4 x 50 min on ON24) ├── docs/ │ ├── module-01-security-foundations.md # Module 1 CliffsNotes │ ├── module-02-core-services-admin.md # Module 2 CliffsNotes │ ├── module-03-data-protection-governance.md # Module 3 CliffsNotes │ ├── module-04-copilot-and-agents.md # Module 4 CliffsNotes │ ├── module-05-copilot-admin-tasks.md # Module 5 CliffsNotes │ ├── module-06-agent-admin-tasks.md # Module 6 CliffsNotes │ ├── session-agenda.md # Instructor delivery guide (4 x 50 min) │ ├── demo-scripts.md # Click-by-click scripts for all 14 demos │ ├── tenant-setup-guide.md # Learner tenant setup before the session │ ├── new-features-deep-dive.md # DSPM for AI, Researcher, Analyst, PAYG │ └── exam-traps-cheatsheet.md # One-page last-minute cheat sheet ├── shared-resources/ │ └── references/ │ ├── AB-900-EXAM-GUIDE.md # Complete exam reference │ ├── AB-900-SKILLS-BREAKDOWN.md # Per-objective study notes │ └── AB-900-PRACTICE-QUESTIONS.md # 15 practice questions (5 per domain) └── segment-0{1-4}-*/ # Per-segment demos, labs, slides, resources ``` --- ## MCP Servers Three MCP servers are configured in `.vscode/mcp.json` and load automatically on clone. | Server ID | Purpose | |-----------|---------| | `ab900buddy-context7` | Version-specific M365 admin PowerShell, Graph API, and CLI syntax | | `ab900buddy-markitdown` | Convert your own PDFs and Word docs to markdown for the agent to analyze | | `ab900buddy-mslearn` | Search and fetch official Microsoft Learn documentation (`microsoft_docs_search`, `microsoft_docs_fetch`) | The Microsoft Learn MCP server (`ab900buddy-mslearn`) is the primary source of truth for all generated questions and walkthroughs.
