What it does
Teams App Developer is an agent skill from microsoft/work-iq, published by the product's own GitHub organization. Build, test, and deploy code-based Teams apps using the M365 Agents Toolkit CLI. USE FOR: Custom Engine Agents (CEA), Teams bots, tabs, message extensions, Agents Playground local testing, Azure provision/deploy, Slack-to-Teams migration, cross-platform bot development, Block Kit to Adaptive Cards conversion, AI model integration (OpenAI/Azure/Anthropic/Bedrock). DO NOT USE FOR: declarative agents — use the declarative-agent-developer skill instead. Triggers: "build a teams bot", "custom engine agent", "CEA"…
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 161 other files (for example `create-project/create-project.md`, `docs/README.md` and `docs/advanced-features.md`).
It sits in DevOps & Cloud, covering Chatbots and conversational support. It works with Microsoft Teams, Microsoft Azure, Slack and Microsoft 365. The repository describes itself as: MCP Server and CLI for accessing Work IQ.
When your agent uses it
- : Custom Engine Agents (CEA)
- Message extensions
- Agents Playground local testing
- Azure provision/deploy
Example prompts
- “build a teams bot”
- “custom engine agent”
- “teams agent”
- “/teams-app-developer”
Requirements
- Python 3
- A credential in AZURE_OPENAI_API_KEY
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Detect ATK Project
- Resolve Common Configuration
- Collect Missing Values
What it can do on your machine
Read from SKILL.md and the folder at commit 1060873. 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:
npmpython
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
Teams App Developer loads about 1.8k tokens when it runs. Until then it costs about 186 tokens; SKILL.md has 717 words of instructions outside code blocks.
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:28
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 717 words (~1,775 tokens).
“Build code-based Microsoft 365 agents and Teams apps (CEA, bot, tab, message extension) using the ATK CLI.”
