Build an Agent That Can Act, Remember, and Improve

Start with one useful Gemini-powered agent. Add typed outputs, sessions, memory, state, knowledge, learning, safety, teams, and workflows. Then launch the whole system in AgentOS.

One API key. No Docker. Every example runs independently.

This is a capability ladder, not a collection of unrelated demos. Each file upgrades the same market-research partner and ends with something you can inspect: a tool call, typed object, stored session, recalled memory, state change, knowledge result, learning, blocked request, approval, team response, or workflow output.

Start Here

From the repository root:

uv venv .venvs/quickstart --python 3.12
source .venvs/quickstart/bin/activate
uv pip install -r cookbook/00_quickstart/requirements.txt
export GOOGLE_API_KEY=your-google-api-key
python cookbook/00_quickstart/agent_with_tools.py

The first example is the complete minimum:

from agno.agent import Agent
from agno.models.google import Gemini
from agno.tools.yfinance import YFinanceTools

agent = Agent(
    model=Gemini(id="gemini-3.6-flash"),
    tools=[YFinanceTools()],
)

agent.print_response("What's AAPL's current price?", stream=True)

Gemini 3.6 Flash is the stable default for this quickstart. It supports the tool calling, structured output, and multi-step agent work used throughout the folder. See the official model page.

The Capability Ladder

Follow the files in order for the full journey, or jump directly to the capability you need. Every example is standalone.

1. Core — Make the Agent Useful

#	Cookbook	What You Add	Proof
01	agent_with_tools.py	Live tools	The agent chooses and calls Yahoo Finance tools
02	agent_with_structured_output.py	Typed output	The run returns a validated Pydantic object
03	agent_with_typed_input_output.py	Input and output contracts	Both sides of the agent boundary are validated

2. Context — Make It Durable

#	Cookbook	What You Add	Proof
04	agent_with_storage.py	Conversation storage	A fixed session continues across runs
05	agent_with_memory.py	User memory	Preferences survive across sessions
06	agent_with_state_management.py	Structured state	The agent updates and restores a watchlist
07	agent_search_over_knowledge.py	Searchable knowledge	The answer is grounded in a versioned local Agno overview
08	agent_with_learning.py	Shared learned knowledge	One user teaches a rule another user can reuse

3. Trust — Keep the Human in Control

#	Cookbook	What You Add	Proof
09	agent_with_guardrails.py	Built-in and custom guardrails	PII, injection, and spam inputs end with RunStatus.error
10	human_in_the_loop.py	Approval gates	The run pauses before a simulated publish action

4. Scale — Move Beyond One Agent

#	Cookbook	What You Add	Proof
11	multi_agent_team.py	Dynamic collaboration	Bull and bear researchers are coordinated by a leader
12	sequential_workflow.py	Explicit orchestration	Gather, analyze, and write steps run in order

5. Ship — Run the Complete System

run.py registers every agent, the team, and the workflow in one AgentOS runtime. config.yaml adds ready-to-run prompts for the AgentOS chat interface.

The Mental Model

These concepts sound similar until you ask what each one owns:

Concept	What It Owns	Use It For
Tools	Actions the model can choose	APIs, search, code, database operations
Structured output	The response contract	Pipelines, APIs, UIs, reliable parsing
Storage	The conversation record	Continue the same thread later
Memory	Durable facts about a user	Preferences and personalization
State	Mutable structured data	Lists, counters, carts, task progress
Knowledge	Information the agent can search	Docs, policies, product data, RAG
Learning	Reusable lessons from prior work	Shared heuristics and better future behavior
Guardrails	Input and output boundaries	Privacy, policy, and validation
Human in the loop	Approval for a pending action	Publishing, writes, payments, deployments
Team	Dynamic delegation between agents	Multiple perspectives or specialists
Workflow	Explicit execution order	Repeatable multi-step processes

Start with one agent. Add a team only when independent specialists improve the answer. Add a workflow when the order of operations must be predictable.

Run the Complete System in AgentOS

Load the local Agno overview used by the knowledge agent once:

python cookbook/00_quickstart/agent_search_over_knowledge.py

Start AgentOS:

python cookbook/00_quickstart/run.py

Open os.agno.com, add http://localhost:7777 as an endpoint, and choose any quickstart agent, team, or workflow. You can chat, inspect sessions, view traces, and explore memory and knowledge from the same interface.

Why Market Research?

The scenario makes agent behavior visible: facts change, tools matter, comparisons benefit from structure, and opposing researchers have a real reason to collaborate. Yahoo Finance also works without a second API key.

The examples teach agent architecture, not investment advice. Replace the tools and instructions with your own domain while keeping the same patterns.

Swap Models

Each file declares its own model so it stays copy-pasteable:

from agno.models.google import Gemini

model = Gemini(id="gemini-3.6-flash")

Replace that model in the example you are using. The memory example also has a dedicated memory model, while the knowledge and learning examples use GeminiEmbedder; those components can be configured independently.

Browse cookbook/90_models/ for other providers and provider-specific capabilities.

Local State

Persistent examples write only to tmp/quickstart/, with a separate SQLite database or Chroma collection per capability. This keeps examples independent and prevents one run from contaminating another. Delete that directory when you want a completely fresh start.

Verify the Folder

Check the cookbook structure and compile every file:

python3 cookbook/scripts/check_cookbook_pattern.py \
  --base-dir cookbook/00_quickstart
python -m compileall -q cookbook/00_quickstart

Use TEST_PROMPT.md for the live behavioral test plan and TEST_LOG.md for the latest verified results.
