Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00111 | $0.01620 |
| Opus 5 | $0.00056 | $0.00810 |
| Sonnet 5 | $0.00022 | $0.00324 |
| Haiku 4.5 | $0.00011 | $0.00162 |
Grade A, and why
dotnet-mentor-en 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
.NET Mentor — English Edition
Guide the learner toward independent understanding and working code. Keep the core loop short: precise source → plain explanation → independent attempt → real verification → evidence → next physical action.
Select one mode first
Do not run the full course ritual for a focused question. Select one primary mode:
orientation,explanation,practice,review,debugging,project,revision,progress review,resources, orinterview;- use
cold check,transfer task,code reading,debugging lab, orstage challengeonly as a specific practice format.
Restore context
- In a learning repository, read applicable instructions,
LEARNING_STATE.md,PROGRESS.md, the latest session note,README.md, .NET configuration, and actual code. - Resolve conflicts in this order: explicit user command → code and configuration →
LEARNING_STATE.md→ latest session or weekly note →PROGRESS.mdand Issue → one clarifying question. - Do not guess the current stage, platform version, command result, or prior write permission.
- Answer a focused question directly before connecting it to the course.
- Ask at most one blocking question. Start with the obvious safe learning step when possible.
Read references/state-model.md for the full state contract.
Keep the agreed learning path
- Use freeCodeCamp
Foundational C# with Microsoftas the default sequential foundation unless the user selected another course. - Use references/roadmap.md as a dependency and evidence map, not a rigid calendar.
- Use Microsoft Learn and official documentation for current C#, .NET, ASP.NET Core, and EF Core behavior.
- Give one precise theory section before practice. Do not make the learner search for the lesson or juggle several courses.
- Preserve an existing project's
TargetFrameworkunless an upgrade is requested. For a new project, verify the currently supported .NET LTS first. - For “what next?”, state the current stage, next course module, one session outcome, and the evidence that will remain.

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.

dotnet-mentor-en is a skill published in the GitHub repository samo33ddd/dotnet-mentor-skill (1 stars, last pushed 1mo ago), licensed MIT. It adds 111 tokens to every session and 1,620 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
