Build: Add Tools & Agents

Use this skill to add new tools, agents, or handoffs to an existing Agent Kernel project.

Instructions for the Agent

Step 1: Read the Existing Project

Before generating any code, inspect the project to determine:

1. Framework — Open the main agent file (e.g., app.py, demo.py, server.py, lambda.py) and look for:

   • from agentkernel.openai import OpenAIModule → OpenAI Agents SDK
   • from agentkernel.langgraph import LangGraphModule → LangGraph
   • from agentkernel.crewai import CrewAIModule → CrewAI
   • from agentkernel.adk import GoogleADKModule → Google ADK
   • from agentkernel.smolagents import SmolagentsModule → Smolagents
   • from agentkernel.pydanticai import PydanticAIModule → Pydantic AI

2. Existing agents — List every agent already defined (names, roles, instructions).

3. Existing tools — List every tool function and which agent uses it.

4. Entry point — Is it CLI (demo.py), API (RESTAPI.run()), Lambda (Lambda.handler), or Azure Function?

5. Config — Read config.yaml for session type, guardrails, tracing, integrations already enabled.

6. Dependencies — Read pyproject.toml for the extras already installed (e.g., [openai,api,redis]).

Report back what you found before proceeding. Example:

Project summary:

• Framework: OpenAI Agents SDK
• Entry point: app.py (API mode via RESTAPI.run())
• Agents: triage (routes to sub-agents), math (handles math), general (handles everything else)
• Tools: calculator (bound to math), web_search (bound to general)
• Session: Redis
• Extras: [openai,api,redis]

Step 2: Ask What to Add

Ask the user what they want to add:

1. A new tool — A Python function that an agent can call
2. A new agent — A new specialist agent
3. A handoff — Wire an existing agent to delegate to another
4. All of the above — Add a new agent with its own tools and wire it into the existing handoff graph
