Builds, tests, and deploys Microsoft 365 apps and agents for Teams and Copilot.

  • Works in 3 steps: Detect ATK Project → Resolve Common Configuration → Collect Missing Values

  • SKILL.md covers Declarative Agent Routing, AI Behavior Guidelines, ATK CLI Setup and CLI Global Options, plus 4 more sections
  • Calls npm and python; needs AZURE_OPENAI_API_KEY

What it does

Microsoft 365 Agents Toolkit is an agent skill from OfficeDev/microsoft-365-agents-toolkit. Builds, tests, and deploys Microsoft 365 apps and agents for Teams and Copilot. Uses WIQD for pure Declarative Agents and DAs backed by existing APIs, MCP servers, or Copilot Connector connections; uses ATK for Declarative Agents with project-owned backend code and deployment and for TypeSpec DA projects. Uses ATK for Custom Engine Agents, Teams bots, tabs, message extensions, Agents Playground, and Teams runtime testing. USE FOR: Declarative Agents, Custom Engine Agents, Teams apps, local testing, deployment…

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 162 other files (for example `create-project/create-project.md`, `docs/README.md` and `docs/advanced-features.md`).

It sits in Documents & Office, covering Cloud office suites and MCP servers. It works with Microsoft 365, Model Context Protocol and Slack. The repository describes itself as: Developer tools for building Teams apps.

When your agent uses it

  • : Declarative Agents
  • Custom Engine Agents
  • Troubleshooting
  • Slack-to-Teams migration

Example prompts

  • “/microsoft-365-agents-toolkit”

Requirements

  • Python 3
  • Node.js
  • A credential in AZURE_OPENAI_API_KEY

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Detect ATK Project
  2. Resolve Common Configuration
  3. Collect Missing Values

What it can do on your machine

Read from SKILL.md and the folder at commit c89a0dd. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • AZURE_OPENAI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Microsoft 365 Agents Toolkit loads about 2.8k tokens when it runs. Until then it costs about 166 tokens; SKILL.md has 1,044 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~166
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:33
    ead error messages carefully. Check `env/.env.local`, `.localConfigs`, and `atk auth list`. Common pitfalls:

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,044 words (~2,820 tokens).

“Build pure Declarative Agents and DAs that use existing APIs, MCP servers, or Copilot Connector connections with WIQD. Use ATK for DAs that own and deploy backend compute, including projects that build and deploy a new Copilot Connector backend, TypeSpec…”
