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 | $0.00033 | $0.00781 |
| Opus 5 | $0.00016 | $0.00391 |
| Sonnet 5 | $0.00007 | $0.00156 |
| Haiku 4.5 | $0.00003 | $0.00078 |
Grade A, and why
microsoft-agent-framework 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 3d 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.

Microsoft Agent Framework
Use this skill when working with applications, agents, workflows, or migrations built on Microsoft Agent Framework.
Microsoft Agent Framework is the unified successor to Semantic Kernel and AutoGen, combining their strengths with new capabilities. Because it is still in public preview and changes quickly, always ground implementation advice in the latest official documentation and samples rather than relying on stale knowledge.
Determine the target language first
Choose the language workflow before making recommendations or code changes:
- Use the .NET workflow when the repository contains
.cs,.csproj,.sln,.slnx, or other .NET project files, or when the user explicitly asks for C# or .NET guidance. Follow references/dotnet.md. - Use the Python workflow when the repository contains
.py,pyproject.toml,requirements.txt, or the user explicitly asks for Python guidance. Follow references/python.md. - If the repository contains both ecosystems, match the language used by the files being edited or the user's stated target.
- If the language is ambiguous, inspect the current workspace first and then choose the closest language-specific reference.
Always consult live documentation
- Read the Microsoft Agent Framework overview first: https://learn.microsoft.com/agent-framework/overview/agent-framework-overview
- Prefer official docs and samples for the current API surface.
- Use the Microsoft Docs MCP tooling when available to fetch up-to-date framework guidance and examples.
- Treat older Semantic Kernel or AutoGen patterns as migration inputs, not as the default implementation model.
Shared guidance
When working with Microsoft Agent Framework in any language:
- Use async patterns for agent and workflow operations.
- Implement explicit error handling and logging.
- Prefer strong typing, clear interfaces, and maintainable composition patterns.
- Use
DefaultAzureCredentialwhen Azure authentication is appropriate. - Use agents for autonomous decision-making, ad hoc planning, conversation flows, tool usage, and MCP server interactions.
- Use workflows for multi-step orchestration, predefined execution graphs, long-running tasks, and human-in-the-loop scenarios.
- Support model providers such as Azure AI Foundry, Azure OpenAI, OpenAI, and others, but prefer Azure AI Foundry services for new projects when that matches user needs.
- Use thread-based or equivalent state handling, context providers, middleware, checkpointing, routing, and orchestration patterns when they fit the problem.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

microsoft-agent-framework is a skill published in the GitHub repository thangchung/agent-engineering-experiment (24 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 781 once invoked, about $0.0002 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.
