Framework Instrumentation

Every supported framework follows the same pattern: pass a flag to init() (or call the framework subpackage’s install() directly for more control), and DecimalAI auto-captures traces, tool calls, and the underlying manifest.

import decimalai
decimalai.init(api_key="dai_sk_...", openai_agents=True)

Supported frameworks

OpenAI Agents SDK

Deepest integration. Full manifest from agent introspection.

LangChain & LangGraph

Callback handler. Chains, AgentExecutor, LangGraph all auto-traced.

LlamaIndex

Query engines, retrievers, synthesizers via the LlamaIndex callback system.

CrewAI

Crews, tasks, agent conversations via OpenTelemetry.

AutoGen / AG2

Conversation-turn-based agents via OpenTelemetry.

Generic OpenTelemetry

Any framework emitting OTel gen_ai.* semantic-convention spans.

Capability comparison

Framework	Auto-detected manifest	Tool schema depth	Handoffs / multi-agent
OpenAI Agents (with `install(agent=...)`)	✅ full	Full schemas	✅
LangChain / LangGraph	✅ full	Full schemas	✅
LlamaIndex	✅ partial	Names only	—
CrewAI	✅ partial	Names only	✅
AutoGen / AG2	✅ partial	Names only	✅ (group chat)
Generic OTel	❌ (register manually)	—	—

“Names only” means DecimalAI knows which tool was called but not its full input schema. If schema-aware manifests matter for your use case (e.g. you want the regression check to flag schema changes), use the explicit register_manifest() form for those frameworks.

Module-level reference

Module	Function	Use it for
`decimalai.openai_agents`	`install(agent=...)`	OpenAI Agents SDK — pass the Agent object for full schema introspection
`decimalai.langchain`	`install()`	LangChain / LangGraph callbacks
`decimalai.llamaindex`	`install()`	LlamaIndex span handler
`decimalai.autogen`	`install()`	AutoGen / AG2 via OpenTelemetry
`decimalai.otel`	`install()`	Generic OpenTelemetry GenAI span exporter

CrewAI ships through the same OTel-based pathway as AutoGen — there’s no decimalai.crewai subpackage; the init(crewai=True) flag is the canonical entry.

What’s next

Tracing

Manual decorators if you need custom span boundaries inside an instrumented framework.

Manifests

Override the auto-detected manifest when needed.
