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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01476 | $0.01476 |
| Opus 5 | $0.00738 | $0.00738 |
| Sonnet 5 | $0.00295 | $0.00295 |
| Haiku 4.5 | $0.00148 | $0.00148 |
Grade A, and why
ai901-cert-buddy-claude CLAUDE.md 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Guidance for Claude Code when working in this repository.
What this is
AI-901 Cert Buddy (Claude Code edition). An agentic study companion for Exam AI-901: Microsoft Azure AI Fundamentals. It generates exam-realistic practice questions, brief hands-on Microsoft Foundry labs, and personalized study plans, all grounded in Microsoft Learn through the Microsoft Learn MCP server.
This project is a Claude Code port of Tim Warner's original GitHub Copilot "Cert Buddy" (az104-cert-buddy, ai901). The point of the port is to show that the same enterprise workflow carries across both agent platforms, one primitive at a time. See README.md for the full primitive map.
There is no application to build. The artifacts are agent definitions, skills, slash commands, hooks, and MCP configuration.

The grounding contract (non-negotiable)
- Microsoft Learn first. Ground every fact about Microsoft Foundry, the Foundry SDK, Azure AI services (Language, Speech, Vision), Azure Content Understanding, Azure OpenAI in Microsoft Foundry, and responsible AI in Microsoft Learn, accessed through the MCP server
ai901buddy-mslearn. - Use
microsoft_docs_searchfor breadth, thenmicrosoft_docs_fetchfor full-page detail, andmicrosoft_code_sample_searchwhen SDK, CLI, or Bicep syntax accuracy matters. - Cite a real Microsoft Learn URL for every question and every lab. Never invent a URL. If you cannot ground a claim, say so and stop.
- Pick objectives from
.claude/skills/_references/ai901-objective-domain.md(a verbatim Microsoft Learn sync).
AI-901 canonical facts
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.
