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 | $0.00474 | $0.00474 |
| Opus 5 | $0.00237 | $0.00237 |
| Sonnet 5 | $0.00095 | $0.00095 |
| Haiku 4.5 | $0.00047 | $0.00047 |
Grade A, and why
Hosted_Agents_Workshop_dotNET AGENTS.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 2d 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.

Repository Purpose
This repo is a beginner workshop for Microsoft Foundry hosted agents with .NET 10.
Primary learning flow:
- Local hosted agent setup and validation
- Copilot customization
- Deterministic tool implementation and tests
- CI validation
- Azure deployment flow
- UI integration and screenshot capture
General Rules
- Keep instructions beginner-friendly and copy-paste ready.
- Prefer placeholder values in docs over real subscription, tenant, endpoint, or registry identifiers.
- Keep examples safe for public sharing.
- Preserve the current lab sequence and avoid reordering labs without a clear reason.
Documentation Rules
- Use short sections and simple language.
- Include expected results for each lab step.
- For any command that depends on user environment, show placeholders:
<account><project><your-acr-name>
- If screenshots are referenced, ensure the files exist in
labs/lab-5-ui/images.
Code and Build Rules
- Target framework is .NET 10.
- Keep deterministic business logic in
src/WorkshopLab.Core. - Keep hosted agent host behavior in
src/WorkshopLab.AgentHost. - Run tests when changing core logic:
dotnet test WorkshopLab.sln
UI Screenshot Workflow
When UI images need refresh for docs:
- Start the app:
dotnet run --project src/WorkshopLab.ChatUI --urls http://localhost:5075
- In another terminal, run screenshot capture:
npm run capture:screenshots
Expected outputs:
labs/lab-5-ui/images/01-chat-ui-landing.pnglabs/lab-5-ui/images/02-chat-ui-prompt-entered.pnglabs/lab-5-ui/images/03-chat-ui-response-hd.png
Public Sharing Checklist
Before publishing updates:
- No hardcoded personal tenant IDs, subscription IDs, or project endpoints
- No hardcoded personal ACR names
.gitignoreincludes local-only artifacts (for examplenode_modules/, local logs, debug outputs)- Beginner docs still read top-to-bottom without hidden assumptions
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.

Hosted_Agents_Workshop_dotNET AGENTS.md is an instructions file published in the GitHub repository microsoft/Hosted_Agents_Workshop_dotNET (23 stars, last pushed 7d ago), licensed MIT. It adds 474 tokens to every session, about $0.0024 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 2026-08-30.
