This PR adds instrumentation for the agent manifest for our LLM Obs agentic integrations (minus LangGraph which will be covered in @sabrenner's [PR](#13904)). I have been using [this doc](https://docs.google.com/document/d/1k-vHYQZfCdckvoH29Mi_TzXuNGBLf3KpypZDpm4vFio/edit?pli=1&tab=t.0) to track what information is available in the Agent Manifest for each integration, but a summary is below: ## Agent Manifest Schema ### Crew AI - Framework - Name - Goal - Backstory - Model - Model Settings - Tools - Handoffs - Code Execution Permissions - Max Iterations <img width="1744" height="918" alt="image" src="https://github.com/user-attachments/assets/d85ac5a7-bbf9-4098-a4a2-93116be6d007" /> ### Open AI Agents - Framework - Name - Instructions - Handoff Description - Model - Model Settings - Tools - Handoffs - Guardrails <img width="1650" height="938" alt="image" src="https://github.com/user-attachments/assets/88f5034c-1846-441d-9495-49ddf7b075ad" /> ### PydanticAI - Framework - Name - Instructions - System Prompts - Model - Model Settings - Tools - Dependencies <img width="548" height="830" alt="image" src="https://github.com/user-attachments/assets/4cbf3466-9de0-475f-808a-43c86e3c45cf" /> ## Next Steps - Make the current Agent Manifest UI work for the new fields that have been added ## Checklist - [x] PR author has checked that all the criteria below are met - The PR description includes an overview of the change - The PR description articulates the motivation for the change - The change includes tests OR the PR description describes a testing strategy - The PR description notes risks associated with the change, if any - Newly-added code is easy to change - The change follows the [library release note guidelines](https://ddtrace.readthedocs.io/en/stable/releasenotes.html) - The change includes or references documentation updates if necessary - Backport labels are set (if [applicable](https://ddtrace.readthedocs.io/en/latest/contributing.html#backporting)) ## Reviewer Checklist - [x] Reviewer has checked that all the criteria below are met - Title is accurate - All changes are related to the pull request's stated goal - Avoids breaking [API](https://ddtrace.readthedocs.io/en/stable/versioning.html#interfaces) changes - Testing strategy adequately addresses listed risks - Newly-added code is easy to change - Release note makes sense to a user of the library - If necessary, author has acknowledged and discussed the performance implications of this PR as reported in the benchmarks PR comment - Backport labels are set in a manner that is consistent with the [release branch maintenance policy](https://ddtrace.readthedocs.io/en/latest/contributing.html#backporting) --------- Co-authored-by: Kyle Verhoog <kyle@verhoog.ca>

looks good so far, had some stylistic comments as well as some things that could be clarified in the agent manifest!

LGTM! Thanks for the thorough clarifications and implementation. All looks good to me :)
Annotates LangGraph agents (compiled state graphs, even those created through `create_react_agent`) with the following agent metadata information: - name (always) - tools (always - best effort, depending on the presence of `ToolNode`s within the agent) - instructions (if done through `create_react_agent`) - model name, provider, & settings (if done through `create_react_agent`) - handoffs (always - assuming the agent is directly a part of a supergraph) - framework (always) - dependencies (since state should always be passed in, always) - max_iterations (always, defaulting to 25 if not provided explicitly) Additionally, to help accomplish this, we patch the `create_react_agent` function to record agent manifest data on agent instance creation, should it be invoked. The means of doing this is a bit strange, as it is in completely different submodule (`langgraph.prebuilt`), and it required me to do what I think are some pretty not normal things for patching 😅 so, happy to discuss/change as needed!
