Add framework-parity harness + CrewAI example - #2201
ayantikanandi18 wants to merge 4 commits into
Conversation
Backs the "framework-agnostic" claim with an actual nightly check instead of a static example list: - scripts/framework_parity/: installs each framework example's own package into an isolated `uv` venv, runs the real `nat validate` CLI against it (structural tier, no credentials needed), and for entries with a single-credential canonical config, actually runs the workflow and inspects the IntermediateStepManager event stream to assert a real LLM span with non-zero token usage was emitted (live tier). Two-tier design and its rationale documented in scripts/framework_parity/README.md. - .github/workflows/framework_parity.yml: runs the matrix nightly (and on PRs touching these paths, structural-only), publishes results as artifacts, and regenerates the badge table in examples/frameworks/README.md on the scheduled/manual run only. - examples/frameworks/crewai_demo/: new CrewAI example, structured as the direct counterpart to semantic_kernel_demo (same two tools, same task, different framework) so the two are comparable side by side. Verified with `nat validate` and a live `nat run` (auth-failing without a real key, which is the expected/correct failure point). ADK already has a full example (adk_demo) contrary to the original brief; left as-is and added to the parity matrix rather than duplicated. Signed-off-by: Ayantika Nandi <ayantikanandi18@gmail.com>

In @.github/workflows/framework_parity.yml:
- Line 19: Replace standalone product terminology “NAT” with “NeMo Agent
Toolkit” in .github/workflows/framework_parity.yml lines 19-19 and
scripts/framework_parity/README.md lines 55-55; retain nat_test_llm unchanged as
a code identifier.
- Around line 68-70: Update the workflow environment configuration around
OPENAI_API_KEY and MEM0_API_KEY so these secrets are not exposed during
pull_request runs, including when --live is used. Restrict exporting both
credentials to scheduled or manually dispatched live-check jobs while preserving
the existing live-check behavior.
- Around line 89-92: Update the publish-table workflow job to run only for
scheduled and manual triggers, preventing pull-request code from executing with
contents: write. Add or use a separate pull-request job with read-only
permissions, and disable persisted credentials in actions/checkout for that job.
In `@examples/frameworks/crewai_demo/pyproject.toml`:
- Line 18: Update the build-system requires list to use two-part
compatible-release specifiers instead of >= constraints, including changing
setuptools and setuptools-scm to forms such as ~=64.0 and ~=8.0 while preserving
the existing dependency names and setuptools_dynamic_dependencies version
intent.
In `@examples/frameworks/crewai_demo/README.md`:
- Line 62: Update the documented nat command to reference the shipped
configuration under src/nat_crewai_demo/configs/ instead of the nonexistent
examples/frameworks/crewai_demo/configs/ path, preserving the existing workflow
and arguments.
- Line 36: Replace the standalone product terminology at
examples/frameworks/crewai_demo/README.md lines 36-36 by changing
“NAT-registered” to “NeMo Agent Toolkit-registered” or equivalent wording; also
update “NAT claims” to “NeMo Agent Toolkit claims” at
scripts/framework_parity/matrix.py lines 18-18.
In `@examples/frameworks/crewai_demo/src/nat_crewai_demo/__init__.py`:

Run the renderer through Python.
render_table.py has no shebang, so this command is not directly executable. Prefix it with python, as the surrounding commands do.

We already have an internal nightly CI that runs all examples. This is superfluous and must be removed.

examples/ already has a README that lists all of the framework examples. I'd prefer the addition of the new demo to go there.
Addresses review feedback on PR NVIDIA#2201: - Removed scripts/framework_parity/ and .github/workflows/framework_parity.yml. An internal nightly CI already runs all examples, so the harness was superfluous. Also reverted the .gitignore entry it needed. - Removed the new examples/frameworks/README.md. examples/README.md already lists every framework example, so crewai_demo is added there instead, in alphabetical order and matching the existing entry format. - Dropped the framework-parity framing from the demo's own README and config docstring, since the harness it referred to no longer exists. Text only; no workflow, tool, or config logic changed. The PR is now just the CrewAI example.

Thanks for the review. Both points make sense, and I have pushed the changes. Removed the framework parity harness and the CI workflow entirely. I did not know about the internal nightly CI that already runs the examples, so the harness was duplicating work that is already covered. I also reverted the .gitignore line it needed. Removed the new examples/frameworks/README.md and added crewai_demo to the existing examples/README.md instead, in alphabetical order and in the same format as the other entries. I also took the framework parity wording out of the demo's own README and its config docstring, since the harness it referred to is gone. That was text only, nothing in the workflow, tools, or config changed. The PR is now just the CrewAI example. |

Branch is now updated with develop, so it is no longer out of date. One open question I would like your call on. Every other framework example is registered in the root pyproject.toml, both in the examples list and in tool.uv.sources. I tried to add nat_crewai_demo there too, but it breaks dependency resolution. The examples extra would then pull in the crewai extra, and crewai is already declared as conflicting with openpipe-art because of incompatible litellm versions. Making that work looks like it needs a change to the conflicts list, which felt like your decision rather than mine, so I left it out. So right now the example is not registered in the root pyproject. Happy to add it whichever way you prefer, or to leave it as is if the internal nightly CI picks up examples a different way. The only failing check is the Label Checker, which needs the category and breaking labels. I do not have permission to add labels to this repo. |

There was a problem hiding this comment.
With both nat_crewai_demo and nat_semantic_kernel_demo installed, hotel_price and local_events are registered twice, and both demos' configs fail nat validate:
Invalid configuration: functions.hotel_price: Input tag 'hotel_price' found using discriminator() does not match any of the expected tags: 'nat_crewai_demo/hotel_price', 'nat_crewai_demo/local_events', ... 'nat_semantic_kernel_demo/hotel_price', 'nat_semantic_kernel_demo/local_events', ...
I ran nat validate --config_file on each demo's configs/config.yml with both installed: both fail. With only the Semantic Kernel demo installed, its config passes. The root examples group already installs nat_semantic_kernel_demo (pyproject.toml:162), so this breaks as soon as the CrewAI demo is added there.
Unique names here and in local_events_tool.py:34 (e.g. crewai_hotel_price, crewai_local_events), plus the matching _type values in configs/config.yml, should avoid it.
This project says it works with many different AI agent frameworks (CrewAI, Semantic Kernel, ADK, and others), but there was no automated way to check that those examples still actually work over time. This adds a nightly check that installs each framework's example fresh and runs it, so we'll know right away if one breaks. It also adds a missing CrewAI example, built to match the existing Semantic Kernel one so they're easy to compare side by side. More details are in scripts/framework_parity/README.md.
