🤔 Why Agently?

Many GenAI POCs fail in production not because models are weak, but because engineering control is missing:

Common challenge	How Agently helps
Output schema drifts, JSON parsing fails	Contract‑first output control with output() + ensure_keys
Workflows get complex and hard to maintain	TriggerFlow orchestration with to / if / match / batch / for_each
Multi‑turn state becomes unstable	Session & Memo with memory, summaries, and persistence strategies
Tool calls are hard to audit	Tool logs via extra.tool_logs
Switching models is expensive	OpenAICompatible unified model settings

Agently turns LLM uncertainty into a stable, testable, maintainable engineering system.

✨ Core Features

1) 📝 Contract‑first Output Control

Define the structure with output(), enforce critical keys with ensure_keys.

result = (
    agent
    .input("Analyze user feedback")
    .output({
        "sentiment": (str, "positive/neutral/negative"),
        "key_issues": [(str, "issue summary")],
        "priority": (int, "1-5, 5 is highest")
    })
    .start(ensure_keys=["sentiment", "key_issues[*]"])
)

2) ⚡ Structured Streaming (Instant)

Consume structured fields as they are generated.

response = (
    agent
    .input("Explain recursion and give 2 tips")
    .output({"definition": (str, "one sentence"), "tips": [(str, "tip")]})
    .get_response()
)

for msg in response.get_generator(type="instant"):
    if msg.path == "definition" and msg.delta:
        ui.update_definition(msg.delta)
    if msg.wildcard_path == "tips[*]" and msg.delta:
        ui.add_tip(msg.delta)

3) 🧩 TriggerFlow Orchestration

Readable, testable workflows with branching and concurrency.

(
    flow.to(handle_request)
    .if_condition(lambda d: d.value["type"] == "query")
    .to(handle_query)
    .elif_condition(lambda d: d.value["type"] == "order")
    .to(check_inventory)
    .to(create_order)
    .end_condition()
)

4) 🧠 Session & Memo (Multi‑turn Memory)

Quick / Lite / Memo modes with summaries and persistence strategies.

from agently import Agently
from agently.core import Session

agent = Agently.create_agent()
session = Session(agent=agent).configure(
    mode="memo",
    limit={"chars": 6000, "messages": 12},
    every_n_turns=2,
)
agent.attach_session(session)

5) 🔧 Tool Calls + Logs

Tool selection and usage are logged in extra.tool_logs.

@agent.tool_func
def add(a: int, b: int) -> int:
    return a + b

response = agent.input("12+34=?").use_tool(add).get_response()
full = response.get_data(type="all")
print(full["extra"]["tool_logs"])

6) 🌐 Unified Model Settings (OpenAICompatible)

One config for multiple providers and local models.

from agently import Agently

Agently.set_settings(
    "OpenAICompatible",
    {
        "base_url": "https://api.deepseek.com/v1",
        "model": "deepseek-chat",
        "auth": "DEEPSEEK_API_KEY",
    },
)

🚀 Quickstart

Install

pip install -U agently

Requirements: Python >= 3.10, recommended Agently >= 4.0.7.2

5‑minute example

1. Structured output

from agently import Agently

agent = Agently.create_agent()

result = (
    agent.input("Introduce Python in one sentence and list 2 advantages")
    .output({
        "introduction": (str, "one sentence"),
        "advantages": [(str, "advantage")]
    })
    .start(ensure_keys=["introduction", "advantages[*]"])
)

print(result)

2. Workflow routing

from agently import TriggerFlow, TriggerFlowEventData

flow = TriggerFlow()

@flow.chunk
def classify_intent(data: TriggerFlowEventData):
    text = data.value
    if "price" in text:
        return "price_query"
    if "feature" in text:
        return "feature_query"
    if "buy" in text:
        return "purchase"
    return "other"

@flow.chunk
def handle_price(_: TriggerFlowEventData):
    return {"response": "Pricing depends on the plan..."}

@flow.chunk
def handle_feature(_: TriggerFlowEventData):
    return {"response": "Our product supports..."}

(
    flow.to(classify_intent)
    .match()
    .case("price_query")
    .to(handle_price)
    .case("feature_query")
    .to(handle_feature)
    .case_else()
    .to(lambda d: {"response": "What would you like to know?"})
    .end_match()
    .end()
)

print(flow.start("How much does it cost?"))

✅ Is Your App Production‑Ready? — Release Readiness Checklist

Based on teams shipping real projects with Agently, this production readiness checklist helps reduce common risks before release.

Area	Check	Recommended Practice
📝 Output Stability	Are key interfaces stable?	Define schemas with output() and lock critical fields with ensure_keys.
⚡ Real‑time UX	Need updates while generating?	Consume type="instant" structured streaming events.
🔍 Observability	Tool calls auditable?	Inspect extra.tool_logs for full arguments and results.
🧩 Workflow Robustness	Complex flows fully tested?	Unit test each TriggerFlow branch and concurrency limit with expected outputs.
🧠 Memory & Context	Multi‑turn experience consistent?	Define Session/Memo summary, trimming, and persistence policies.
📄 Prompt Management	Can logic evolve safely?	Version and configure prompts to keep changes traceable.
🌐 Model Strategy	Can you switch or downgrade models?	Centralize settings with OpenAICompatible for fast provider switching.
🚀 Performance & Scale	Can it handle concurrency?	Validate async performance in real web‑service scenarios.
🧪 Quality Assurance	Regression tests complete?	Create fixed inputs with expected outputs for core scenarios.

❓ FAQ

Q: How is Agently different from LangChain or LlamaIndex?
A: Agently is built for production. It focuses on stable interfaces (contract‑first outputs), readable/testable orchestration (TriggerFlow), and observable tool calls (tool_logs). It’s a better fit for teams that need reliability and maintainability after launch.

Q: Which models are supported? Is switching expensive?
A: With OpenAICompatible, you can connect OpenAI, Claude, DeepSeek, Qwen and most OpenAI‑compatible endpoints, plus local models like Llama/Qwen. The same business code can switch models without rewrites, reducing vendor lock‑in.

Q: What’s the learning curve? Where should I start?
A: The core API is straightforward—you can run your first agent in minutes. Start with Quickstart, then dive into Output Control and TriggerFlow.

Q: How do I deploy an Agently‑based service?
A: Agently doesn’t lock you into a specific deployment path. It provides async APIs and FastAPI examples. The FastAPI integration example covers SSE, WebSocket, and standard POST.

Q: Do you offer enterprise support?
A: Yes. The core framework in this repository remains open‑source under Apache 2.0. Enterprise support, private extensions, managed services, and SLA-based collaboration are provided under separate commercial agreements. Contact us via the community.

Q: What is open-source vs enterprise in Agently?
A: The open-source core includes the general framework and public capabilities in this repository. Enterprise offerings (for example private extension packs, advanced governance modules, private deployment support, and SLA services) are delivered separately under commercial terms.
