az104-cert-buddy: Skill for Claude Code

.github/skills/az104-lab-creator/SKILL.md

az104-lab-creator is a skill for Claude Code, Codex from timothywarner-org/az104-cert-buddy. It costs 63 tokens per session (1,203 once invoked), scanned A, original, MIT.

A tool for creating short, hands-on practice labs for the AZ-104 Microsoft Azure Administrator exam. Each lab is designed to run in 10–20 minutes and includes setup, exact tasks, checks, expected results, and cleanup.

In plain words
What is it for?
Use it to create executable Azure administration exercises with prerequisites, validation steps, expected outputs, and resource cleanup.
Why use it?
It turns Azure study into guided exercises that can be verified as they are completed. Cleanup instructions help remove the resources created during practice.

Written for no agent in particular: nothing here depends on one.

This is timothywarner-org/az104-cert-buddy's own configuration. It tells Claude Code and Codex how to work on az104-cert-buddy itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything az104-cert-buddy configures →

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

az104-lab-creator scanned grade A with 0 findings 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 11d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skill: az104.practice_labs.micro.validated

Description: Create short AZ-104 practice labs (10-20 minutes) that are executable and self-validating. Every lab includes prerequisites, exact tasks, validation steps, expected outputs, and cleanup.

Grounding

Required sources:

  • Microsoft Learn (primary truth source for architecture and correct configuration; access via the Microsoft Learn MCP server using microsoft_docs_search and microsoft_docs_fetch)
  • Microsoft Learn code samples (for CLI/PowerShell/Bicep accuracy; access via microsoft_code_sample_search)

Style

Microsoft style:

  • Use Microsoft instruction formatting conventions for UI labels, commands, and dialog names.
  • See references/style-guide.md for detailed Microsoft writing style rules.
  • Bold for clickable UI elements. Input-neutral verbs: select (not click), enter (not type).

Guardrails

  • Keep the lab within AZ-104 scope (admin tasks, not deep dev).
  • Prefer lowest-cost resources; include a cost warning if not.
  • No contractions.
  • No ambiguous "click around until" steps.
  • Always include cleanup steps that remove created resources.
  • Always use current Microsoft product names. Never use retired names such as "Azure AD" (use "Microsoft Entra ID"), "Azure AD Connect" (use "Microsoft Entra Connect"), and so on. See the full rename table in .github/copilot-instructions.md. If a lab touches identity or governance, double-check every product name against current terminology.

Fictional company randomization (non-negotiable)

Use fictional company names from references/fictional-companies.md for any scenario context in lab titles or descriptions. You MUST randomize the company selection -- do not default to Contoso for every lab. Draw from the full list of 50+ companies.

Timebox guidance

A lab should contain no more than 12 steps total across all tasks. If the lab requires more than 12 steps, it likely exceeds the 20-minute timebox. In that case, split the content into two separate labs, each focused on a narrower objective.

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.
