Microsoft Agent 365 Skills is a collection of coding-agent skills and MCP configuration for building and operating AI Teammates hosted in Microsoft Teams. It supports the Agent 365 lifecycle, including WorkIQ integration, registration, observability, validation, and local testing, for users of Claude Code and GitHub Copilot.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00125 | $0.11036 |
| Opus 5.5 | $0.00050 | $0.04414 |
| Sonnet 5.5 | $0.00025 | $0.02207 |
| Haiku 4.5 | $0.00013 | $0.01104 |
Grade D, and why
a365-setup scanned grade D with 3 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 2mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Agent 365 CLI Setup
Trigger phrases — any of these will activate this skill automatically:
- "set up agent 365 for this agent"
- "run a365 setup"
- "onboard this agent to agent 365"
- "register this agent with agent 365"
- "provision this agent with agent 365"
- "add agent 365 to this agent"
- "connect this agent to agent 365"
- "make this agent an a365 agent"
- "make this agent discoverable in Agent 365"
- "create a365 blueprint"
- "start agent 365 setup"
YOUR VERY FIRST ACTION: Output the intro message below to the user, then silently detect the agent stack. Do NOT create todos, run setup commands, or read further until all Phase 1 questions are answered.
MANDATORY INTRO MESSAGE — output this before doing anything else:
I'll help you set up Agent 365 for this agent. Here's what I'll do:
1. Detect your agent type, stack, and language (silently, takes a few seconds)
2. Ask you to confirm what I found — or correct anything I got wrong
3. Ask how your agent authenticates (OBO / S2S)
4. Ask which capabilities you want (Register, Observability, WorkIQ, AI Teammate)
After those answers, I'll install any missing prerequisites, validate your Azure
environment, and hand off to the right skill for the rest of setup.
Detecting your agent now…
RULE 1 — DETECT AGENT STACK AND CODE, ASK VALIDATION QUESTIONS, THEN CREATE ALL TODOS.
Phase 1A: Silent Detection
First: Check for detection cache. Read .a365-workspace-detection.local.json if it exists. If detectedAt is within the last 60 minutes, load agentStack, programmingLanguage, and usesTeamsOrCopilot from it and skip the detection steps below — go straight to Phase 1B.
Run all three detection steps in parallel (single tool call with multiple Glob/Grep):
Step 1: Detect Agent Stack → Store as agentStack
- Check for .csproj + Microsoft.Agents.* →
Agent Framework - Check for package.json + @langchain →
LangChain - Check for package.json + "openai" (no LangChain) →
OpenAI - Check for requirements.txt + langchain →
LangChain - Check for requirements.txt + openai →
OpenAI
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.

a365-setup is a skill published in the GitHub repository microsoft/agent365-skills (51 stars, last pushed 17d ago), licensed MIT. It adds 125 tokens to every session and 11,036 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
