validator scans all skill documents and preserves the commit-time stale-path
enforcement described in AGENTS.md.
In `@skills/bionemo-recipes-acceleration/assets/conftest.py.tmpl`:
- Line 36: Move the pytest_plugins declaration from the generated

- Around line 52-66: Update the module-level ALL_RECIPES and
RECIPE_SUPPORT_CHECKS setup to resolve recipe classes, constructors, and support
checks lazily via optional lookups, including NVFP4BlockScaling kwargs. When a
required Transformer Engine symbol or constructor is unavailable, represent that
recipe as unsupported rather than raising during import, so unrelated BF16
parity tests can still collect and run.
In `@skills/bionemo-recipes-acceleration/references/precision-selection.md`:
- Around line 134-135: Update the precision-selection instructions around
ranking supported recipes to define deterministic no-benchmark behavior: when no
modes succeed, and when only one recipe is supported, explicitly represent
unavailable winner, runner-up, and margin values in
.bionemo-accel/precision.json and the generated report rather than requiring
nonexistent data. Ensure the fallback remains compatible with Phase 3’s
supported_recipes path.
In `@skills/bionemo-recipes-acceleration/scripts/probe_hardware.py`:
- Around line 264-269: Update the exception handling in
ensure_transformer_engine, probe_torch, and the Transformer Engine import probe
to catch non-ImportError import failures such as OSError and RuntimeError,
returning the existing documented unavailable/error result with a readable
exception message instead of propagating a traceback.

- Around line 164-165: Update the FP8 gating condition in the benchmark argument
construction to append --no-fp8 only when none of the four FP8 recipe
capabilities, including DelayedScaling, Float8CurrentScaling, and the existing
block-scaling recipes, are supported. Preserve the current flag behavior for
hardware supporting any FP8 recipe.
In `@skills/bionemo-recipes-acceleration/SKILL.md`:
- Line 59: Format the content under the “Examples” section using the
repository’s configured Ruff and Markdown formatters, and retain the resulting

- Around line 56-57: Update the Megatron-LM routing instruction in the skill
documentation to select the recipe based on the requested architecture,
distinguishing between eden_megatron and evo2_megatron; do not route every
Megatron-LM request to evo2_megatron unless the documented architecture mapping
explicitly supports that behavior. Keep the existing vLLM inference route
unchanged.
- Around line 214-216: Update the hardware capability-to-benchmark flag mapping
in the benchmark setup to derive --no-fp8 and --no-fp8-block independently from
hardware.json: --no-fp8 must control only MXFP8, while --no-fp8-block must
control Float8BlockScaling and prevent unsupported MXFP8BlockScaling from
running. Preserve the existing behavior for other recipe support checks and
non-zero probe exits.

Phase 0 always creates .bionemo-accel/inventory.json and edits the target .gitignore before Phase 1. The hard-stop contract later says that only ACCELERATION_REPORT.md is written and no other files are modified. Defer these writes until after matching, or explicitly exempt them from the hard-stop guarantee.

…pths test_golden_values_thd is the packing correctness proof in the BaseModelTest harness. Previously Tier 2 was only triggered when Depth B produced a converter, which meant Depth A ports with THD packing enabled skipped it.

Previously --no-fp8 was omitted whenever any block-scaled recipe (Float8BlockScaling or MXFP8BlockScaling) was in supported_recipes. This let Float8BlockScaling get benchmarked on hardware where MXFP8BlockScaling was supported but Float8BlockScaling was not, since Float8BlockScaling and MXFP8BlockScaling have separate TE check functions. Rename BLOCK_SCALED_FP8_RECIPES -> ALL_FP8_RECIPES to include DelayedScaling and Float8CurrentScaling. --no-fp8 is now appended only when no FP8 recipe of any kind is supported; if any one is present the benchmark decides what to run. Also correct the stale Hopper guidance in precision-selection.md: Hopper supports standard FP8, so --no-fp8 should not be added there.

Mixed models can have a mixture of TE layers and API conforming non-TE layers. For example there is our evo2 recipe with a mixture of hyena layers (the internals of which do use TE wherever there is support, eg linear and norm sub-components). Even within a mamba layer, if you look at the mcore definition https://github.com/NVIDIA/Megatron-LM/blob/main/megatron/core/ssm/mamba_layer.py they use TE layers where possible (eg for layernorm within the mamba layer), and non-Te in other places. Gated Delta Net is another example like that, also in the megatron ssm directory.
I think the skill's refusal rules are likely too stringent. For example you may be able to swap out some of the linear/norm/etc layers in a GNN, diffusion, or state space model with TE variants and get a win, even if some key operations are not supported.
There was a problem hiding this comment.
The unsupported ops would need to conform to TE standards, and properly handle parallelisms. That's work for sure. There would need to be equivalency testing covering forward and backwards under different mixtures of parallelism (out of scope for CI but good for a skill to implement). Examples of those kinds of tests are in the evo2_megatron recipe.

would it be hard for packing to be implemented at this level? that is a bit surprising. I would assume that most of the complexity for packing is in the te attention layer which would be one of the swaps, and that would support THD, so it would be an issue of making sure that the various layers are called in the right way, probably following the internal call patterns of te.TransformerLayer?
I'm less clear on the other ones. quantized model init not working in this case is a bit surprising too.

So there are examples of diffusion models in megatron bridge that use a mixture of custom and TE layers. For example: https://github.com/NVIDIA-NeMo/Megatron-Bridge/blob/main/src/megatron/bridge/diffusion/models/common/nemotron_labs_diffusion_attention.py which is the custom attention layer for their diffusion model, and https://github.com/NVIDIA-NeMo/Megatron-Bridge/blob/main/src/megatron/bridge/diffusion/models/nemotron_labs_diffusion/nemotron_labs_diffusion_provider.py#L47 shows how that custom attention is being hot-swapped into a standard transformer model that uses TE layers elsewhere. It's just the core_attention that looks like it needs to be swapped and everything else can stay the same?

These models are the same story as above for diffusion. You can create mixtures of TE and non-TE layers. You already have a section in the skill somewhere I remember skimming by that talk about how to go up the heirarchy in some cases and fall back to using the individual layer types rather than the top level te.TransformerLayer. This would be another of those cases.

I am not sure how to interpret this. Maybe things like sliding window attention? It looks like TE supports that... Maybe the thing to do would be to have the agent refer to our recipes wherever possible, and then point it at TE docs and/or the models in repos like megatron bridge or megatron-lm for inspiration when going outside of what we have demonstrated?

Description
Adds the bionemo-recipes-acceleration agent skill, which ports external PyTorch/HuggingFace model codebases onto the Transformer Engine acceleration patterns proven in BioNeMo Recipes (FP8/MXFP8/NVFP4 quantization, fused TransformerLayer, THD sequence packing, quantized_model_init). The skill measures precision choice with TE's own GEMM benchmark, rewrites the model at the appropriate depth (A–C), and validates the port with the shared BaseModelTest CI harness. Hard-stops with a report only for architectures with no TE analogue (diffusion, GNN/equivariant, state-space).
Also adds a .claude/skills/bionemo-phage-generation symlink so the phage generation skill is discoverable by Claude Code alongside this one.
Usage
Invoke from any agentic CLI (Claude Code, Codex) inside the target model's training environment:
export BIONEMO_RECIPES=/path/to/bionemo-recipes-checkout then in your agent session:
"Add FP8 training to my ESM2 fine-tuning script in /workspace/my_model/"
The skill runs scripts/probe_hardware.py and scripts/run_gemm_benchmark.py automaticalpeline and writes all artifacts under .bionemo-accel/ in the target repo.
