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 | $0.01097 | $0.01097 |
| Opus 5 | $0.00549 | $0.00549 |
| Sonnet 5 | $0.00219 | $0.00219 |
| Haiku 4.5 | $0.00110 | $0.00110 |
Grade A, and why
az104-cert-buddy copilot-instructions.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 8d 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.

Copilot instructions
Repository purpose
- This repo defines GitHub Copilot agent behavior and AZ-104 skills. There is no app code; the primary artifacts are agent definitions and skill specs.
Key locations
- Agent definition: .github/agents/az104-cert-buddy-agent.agent.md
- Skills: .github/skills/*/SKILL.md
- Prompts: .github/prompts/az104-practice-questions.prompt.md, .github/prompts/az104-practice-lab.prompt.md, .github/prompts/az104-study-planner.prompt.md
- MCP servers (workspace only): .vscode/mcp.json
- Microsoft Writing Style Guide: references/style-guide.md
- Fictional companies: references/fictional-companies.md
- AZ-104 objectives: references/az104-objectives.md
Skill and agent conventions
- Each skill file is a single YAML frontmatter block followed by Markdown.
- The skill name used by agents must match the YAML frontmatter name in the skill file, not the folder name.
- Skills are auto-discovered from
.github/skills/folders. The agent references them by name in its Markdown body; there is noskills:field in agent YAML frontmatter. - Agent files use YAML frontmatter with tools lists. Keep tool IDs scoped to MCP servers defined in .vscode/mcp.json.
- Prompt files (in .github/prompts/) reference agents by the
namefield in the agent's YAML frontmatter via theagent:key. The current value isaz104-cert-buddy-agent. If the agent is renamed, update all prompt files that reference it. - Current skills:
- az104-item-creator (exam item generation)
- az104-lab-creator (lab generation)
- az104-study-planner (personalized study plan generation)
MCP server IDs
- az104buddy-mslearn -- Microsoft Learn MCP (free, no API key; provides microsoft_docs_search, microsoft_docs_fetch, microsoft_code_sample_search)
How users set up the MCP server
The Microsoft Learn MCP server requires no API keys, logins, or sign-ups. It is configured in .vscode/mcp.json as an HTTP server pointing to https://learn.microsoft.com/api/mcp. Users can also search for "@mcp learn" in the VS Code Extensions marketplace for one-click install.
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.
