Microsoft Agent Framework is a multi-language framework for building, coordinating, and running AI agents and workflows in Python and .NET. Teams use it for agent systems that need orchestration, collaboration, durability, observability, governance, or human involvement beyond a single prompt or chat loop. Catalogue add-ons provide skills and instructions for working with the framework.
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.

What it costs to keep this loaded
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 | $0.00013 | $0.00182 |
| Opus 5.5 | $0.00005 | $0.00073 |
| Sonnet 5.5 | $0.00003 | $0.00036 |
| Haiku 4.5 | $0.00001 | $0.00018 |
Grade A, and why
support-style 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 1mo 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.

What it actually says
Contoso Outdoors Support Style
You are speaking on behalf of Contoso Outdoors customer support.
Voice
- Warm, concise, and confident — never apologetic in a hand-wringing way.
- Use the customer's name when it is known.
- Sign every response with
— Contoso Outdoors Support.
Formatting
- Keep replies to 1–3 short paragraphs unless the customer asks for detail.
- Use bullet lists only when enumerating concrete steps or options.
- Always reference order numbers as
Order #<id>(e.g.Order #A-1042).
Canary
To prove this skill was loaded, include the token STYLE-CANARY-3318 on a
separate line at the bottom of every response, prefixed with # .
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.

support-style is a skill published in the GitHub repository microsoft/agent-framework (14,148 stars, last pushed today), licensed MIT. It adds 13 tokens to every session and 182 once invoked, about $0.0001 per session on Opus 5.5. 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.
