test-local
Runs an Agent 365 AI Teammate agent locally and opens AgentsPlayground for interactive local testing. Works with any AI Teammate stack — .NET (AgentFramework, Semantic Kernel), Node.js (LangChain, OpenAI, Claude SDK, Semantic Kernel, Google ADK), or Python (AgentFramework, LangChain, OpenAI, Claude, Semantic Kernel, Google ADK). Checks prerequisites (agentsplayground CLI, build tools), builds the agent, starts it in the background, and launches the playground UI pointed at the local endpoint. AgentsPlayground connects to /api/messages over HTTP — the LLM framework does not matter.
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.
TaskCreate: "Detect agent type and verify build tools"
TaskCreate: "Install agentsplayground"
TaskCreate: "Build agent"
TaskCreate: "Launch agent and AgentsPlayground"
TaskCreate: "Guide local test"
Phase 1 — Detect Agent Type

Determine default port:
- .NET:
5000(HTTP,dotnet rundefault) - Node.js:
3978(standard Bot Framework port) - Python:
3978(aiohttp default in AI Teammate hosting layer) - If the user provided a port as the skill argument, use that instead.
- .NET:
-
Determine start command:
- .NET:
dotnet run - Node.js:
npm start(fall back tonpm run devifstartscript absent) - Python: detect entry point — check for
host_agent_server.py,app.py, ormain.py. Detect the Python command:python3 --version 2>/dev/null && echo python3 || echo python. Usepython3if available (macOS/Linux default), otherwisepython(Windows). Run with<python-cmd> <entry>(oruvicorn app:app --port 3978if an ASGI app is detected).
- .NET:
-
If agent type cannot be determined, stop and ask:
AskUserQuestion:
question: "I couldn't detect the agent type. What are you working with?"
options:
- .NET (AgentFramework or Semantic Kernel)
- Node.js (LangChain, OpenAI, Claude SDK, Semantic Kernel, or Google ADK)
- Python (AgentFramework, LangChain, OpenAI, Claude, Semantic Kernel, or Google ADK)
1.3 — Check language build tool
After detection, immediately verify the required build tool is installed:
For .NET — check dotnet --version. If missing or below 8.0:
AskUserQuestion:
question: "dotnet SDK 8.0+ is required but not found. Install it now?"
options:
- "Yes — install it for me"
- "No — I'll install manually and re-run"
If yes, show the appropriate command for the detected OS and ask the user to run it:
Windows: winget install Microsoft.DotNet.SDK.8
macOS: brew install --cask dotnet-sdk
Linux: sudo apt-get update && sudo apt-get install -y dotnet-sdk-8.0
(or: https://learn.microsoft.com/en-us/dotnet/core/install/linux)
All: https://dotnet.microsoft.com/download
After install, restart the terminal then run dotnet --version to confirm.
For Node.js — check node --version. If missing or below 18:
AskUserQuestion:
question: "Node.js 18+ is required but not found. Install it now?"
options:
- "Yes — install it for me"
- "No — I'll install manually and re-run"
If yes, show the appropriate command:
Windows: winget install OpenJS.NodeJS.LTS
macOS: brew install node
Linux: sudo apt-get update && sudo apt-get install -y nodejs npm
(or via nvm: curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash && nvm install --lts)
All: https://nodejs.org (LTS)
After install, run node --version to confirm.
For Python — check python3 --version 2>/dev/null || python --version. If missing or below 3.11:
AskUserQuestion:
question: "Python 3.11+ is required but not found. Install it now?"
options:
- "Yes — install it for me"
- "No — I'll install manually and re-run"
If yes, show the appropriate command:
Windows: winget install Python.Python.3.11
macOS: brew install python@3.11
Linux: sudo apt-get install -y python3.11 python3.11-venv python3-pip
All: https://python.org
After install, confirm with python3 --version 2>/dev/null || python --version.
Mark task complete: "Detect agent type and verify build tools"
Phase 2 — Install agentsplayground
Mark task in progress: "Install agentsplayground"
Check if installed:
agentsplayground --version
If found, report the version and continue.
If not found, ask the user:
"AgentsPlayground CLI is not installed. Install it now with
npm install -g @microsoft/agentsplayground?" Options: Yes, install it / No, I'll install it manually
If the user chooses Yes:
npm install -g @microsoft/agentsplayground
Verify the install succeeded:
agentsplayground --version
If installation fails or the user chooses No, stop and tell the user:
"Install agentsplayground manually with:
npm install -g @microsoft/agentsplaygroundthen re-run this skill."
Do NOT continue if agentsplayground cannot be confirmed installed.
Mark task complete: "Install agentsplayground"
Phase 3 — Build Agent
Mark task in progress: "Build agent"
For .NET
dotnet build
For Node.js
npm install
npm run build || npm run compile || echo "No build script — skipping compile check"
For Python
# Use pip3 on macOS/Linux, pip on Windows — try pip3 first
pip3 install -r requirements.txt 2>/dev/null || pip install -r requirements.txt || pip install .
# Verify the active Python version (use python3 on macOS/Linux, python on Windows)
python3 --version 2>/dev/null || python --version
If build fails, show the error output and stop:
"Fix the build errors above and re-run this skill to continue."
Do NOT attempt to launch a broken build.
Mark task complete: "Build agent"
Phase 4 — Launch Agent and AgentsPlayground
Mark task in progress: "Launch agent and AgentsPlayground"
4.1 — Ask user before launching
AskUserQuestion:
question: "Ready to start the agent and open AgentsPlayground for a local test?"
options:
- "Yes — start agent and open playground"
- "No — show me the commands and I'll run them manually"
4.2 — If yes: launch
Inform the user:
Two terminals are needed. Starting both now.
Start the agent (terminal 1) — command varies by language:
- .NET:
dotnet run - Node.js:
npm start(fall back tonpm run dev) - Python:
python3 <entry-point>on macOS/Linux (e.g.python3 host_agent_server.py);python <entry-point>on Windows
Note for .NET: The
-c "emulator"flag bypasses Bot Framework auth. This works becauseMapAgentApplicationEndpointswithrequireAuth: falseskips token validation for local traffic. No config changes are needed for Node.js or Python.
Poll until the agent responds (max ~20 s), then launch AgentsPlayground — same command for all stacks:
# Poll until agent responds (works on Windows/macOS/Linux — no seq dependency)
for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
curl -s --max-time 1 "http://localhost:<port>/api/messages" > /dev/null 2>&1 && break
sleep 1
done
agentsplayground -e "http://localhost:<port>/api/messages" -c "emulator"
4.3 — If no: show commands
Present the commands for the user to run in two terminals:
Terminal 1 — start your agent:
.NET: dotnet run
Node.js: npm start
Python (macOS/Linux): python3 host_agent_server.py (or python3 app.py / python3 main.py)
Python (Windows): python host_agent_server.py (or python app.py / python main.py)
Terminal 2 — open AgentsPlayground (same for all stacks and platforms):
agentsplayground -e "http://localhost:<port>/api/messages" -c "emulator"
Mark task complete: "Launch agent and AgentsPlayground"
Phase 5 — Guide Local Test
Mark task in progress: "Guide local test"
Tell the user:
AgentsPlayground is open. Send a message in the chat window to test your agent.
What to watch for:
- Agent responds — confirms the messaging stack is wired correctly.
- Terminal logs — if observability is instrumented, look for these signals in this order:
TheAgent365Exporter: Exporting batch of N spans. [Agent365Exporter] M non-genAI spans filtered out [Agent365Exporter] Partitioned into K identity groups (X spans skipped) Agent365ExporterCore: Obtained token for agent <agentId> tenant <tenantId>. Agent365ExporterCore: Sending chunk 1 of 1 (J spans, B bytes) to https://agent365.svc.cloud.microsoft/observability/tenants/<tenant>/otlp/agents/<agent>/traces?api-version=1. Agent365ExporterCore: HTTP 200 exporting spans. 'x-ms-correlation-id': '<guid>'.HTTP 200 exporting spansline is the definitive confirmation that traces reached the A365 backend.Partitioned into K identity groupsshould showK >= 1for at least one batch after a Teams turn — if it's always0, the agent/tenant ID is missing from baggage (likely theGuid.Emptyfallback bug — verifyinstrument-observabilitywas followed correctly). To see these logs you needMicrosoft.Agents.A365.Observability: Debug(or lower) inappsettings.json'sLogging:LogLevel.To export traces to the A365 service (not just console):
- .NET: set
EnableAgent365Exporter: trueinappsettings.json(SDK defaults tofalsewhen key is absent)- Node.js / Python: set
ENABLE_A365_OBSERVABILITY_EXPORTER=truein.envStopping the agent: Press
Ctrl+Cin Terminal 1.
If the user reports the agent is not responding, suggest:
- Confirm the port matches (check the startup log for the listening URL)
- .NET: check
MapAgentApplicationEndpointsis called withrequireAuth: false - Node.js: check the express listener port in
index.ts - Python: check the aiohttp port in
host_agent_server.pyorapp.py
Mark task complete: "Guide local test"
Phase 6 — Final Summary
-
TaskList — Show all completed tasks.
-
Present summary:
✅ Local test session ready!
Agent: [language + framework, e.g. Python · AgentFramework]
Agent endpoint: http://localhost:<port>/api/messages
AgentsPlayground: running (emulator mode — no auth required)
Observability check:
If instrumented — watch terminal for:
"Agent365ExporterCore: HTTP 200 exporting spans. 'x-ms-correlation-id': ..."
(and "Partitioned into K identity groups" with K >= 1)
Requires Microsoft.Agents.A365.Observability: Debug in Logging:LogLevel.
To export to A365 service:
.NET: set EnableAgent365Exporter: true in appsettings.json
Node.js/Python: set ENABLE_A365_OBSERVABILITY_EXPORTER=true in .env
To stop: Ctrl+C in the agent terminal.
Error Handling
| Situation | Action |
|---|---|
| agentsplayground install fails | Report error; show manual install command; stop |
| Build fails | Show error; do not launch; stop |
| Agent port already in use | Suggest --port <other> or kill the existing process |
| Playground cannot connect | Check agent is listening; verify port matches |
Node.js npm start not found | Try npm run dev; if neither, ask user for start command |
| Python entry point unclear | Check for host_agent_server.py, app.py, or main.py; ask user if ambiguous |
| Python port mismatch | Check aiohttp port in entry point; default is 3978 for AI Teammate hosting |
