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-item-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 2mo 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_questions.exam_realistic

Description: Generate AZ-104 practice questions that feel like the real exam without copying it. Every item is grounded in current Microsoft Learn content, uses modern Azure terminology, and follows Microsoft-style exam item rules (scenario-first, plausible distractors, no trick wording).

Grounding

Required sources:

  • Microsoft Learn (primary truth source for objectives + features; access via the Microsoft Learn MCP server using microsoft_docs_search and microsoft_docs_fetch)
  • Microsoft Learn code samples (for CLI/PowerShell/SDK accuracy; access via microsoft_code_sample_search)

Study guide:

  • Study guide for Exam AZ-104: Microsoft Azure Administrator (skills outline + objective mapping) [Microsoft Learn]
  • references/az104-objectives.md for the full skills-measured list

Style

Microsoft style:

  • Follow Microsoft sentence-style capitalization and UI-label rules.
  • See references/style-guide.md for detailed Microsoft writing style rules. Key rules for exam items:
    • Sentence-style capitalization everywhere except proper nouns and product names.
    • Bold for UI element names.
    • Input-neutral verbs: select (not click), enter (not type).
    • Imperative mood in procedure steps.
    • Oxford comma in all lists.
    • No contractions.
    • on-premises (never on-premise), cloud-native (hyphenated before a noun).
    • Spell out zero through nine; numerals for 10 or greater.
    • should for recommendations, must for requirements.

Guardrails

Exam integrity:

  • Do not recreate or paraphrase real exam questions.
  • Do not reference braindumps or leaked content.
  • Write original scenarios and original stems every time.

Terminology:

  • 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 distractor references identity or governance, double-check that every product name is current.

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.
