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
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00133 | $0.04238 |
| Opus 5 | $0.00067 | $0.02119 |
| Sonnet 5 | $0.00027 | $0.00848 |
| Haiku 4.5 | $0.00013 | $0.00424 |
Grade D, and why
test-local 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 5d 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.
Linux: sudo apt-get update && sudo apt-get install -y dotnet-sdk-8.0 Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

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

The opening of the file, as written. The whole thing — 417 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Test Agent Locally (AgentsPlayground)
Trigger phrases — any of these will activate this skill automatically:
- "test this agent locally"
- "run my agent locally"
- "open agentsplayground"
- "launch agentsplayground"
- "start a local test session"
- "debug this agent locally"
- "test my agent without deploying to teams"
- "spin up a local test"
Overview
This skill starts your agent on localhost and opens AgentsPlayground — a local web UI that simulates a Teams-like chat interface without requiring a deployment or Bot Framework auth.
What it does:
- Detects agent language and framework (.NET, Node.js, or Python)
- Checks agentsplayground is installed — installs if missing
- Builds the agent to confirm there are no compile errors
- Starts the agent in the background
- Launches AgentsPlayground pointed at the local endpoint
- Guides a local test and confirms observability logs are flowing (if instrumented)
Why AgentsPlayground works for all AI Teammate stacks:
- Web UI that matches the Teams message format
- Connects to
/api/messagesover HTTP — the LLM framework on the server side does not matter - The
-c emulatorflag bypasses Bot Framework auth — no extra config needed for any stack requireAuth: falseinMapAgentApplicationEndpointsis the only .NET-specific prerequisite
All actions are read-only against your codebase — no code is modified.
Phase 0 — Create and Display Task List
Show the user this checklist BEFORE Phase 1. Exactly one task in_progress at a time; complete before moving on. Use whichever mechanism the runtime supports:
- Claude Code: call
TaskCreatefor each item below (already inallowed-tools); the list renders natively. UseTaskUpdateto flip statuses.- VS Code Copilot Chat / GitHub Copilot CLI:
allowed-toolsis ignored — emit a markdown checklist directly in chat (- [ ] Detect agent type…) and edit items to- [x]as each phase completes.
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.

test-local is a skill published in the GitHub repository microsoft/agent365-skills (34 stars, last pushed 9d ago), licensed MIT. It adds 133 tokens to every session and 4,238 once invoked, about $0.0007 per session on Opus 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.
