- Add ENV_/ARCH_ failure-class distinction: dep install failure is ENV_, never an architectural judgment; forward-pass blocked by missing deps is ENV_ not ARCH_ - Phase 0 now installs target pyproject.toml/requirements.txt before architecture matching so the target's own deps don't produce false hard-stops - Derive GEMM benchmark skip flags from probe's supported_recipes list instead of hardcoded Hopper check, connecting the two pipeline steps - summary.json written only for successful benchmark modes; a benchmark failure is non-fatal and the port proceeds with available data - Add .claude/skills/bionemo-phage-generation symlink for Claude Code discovery of the merged phage generation skill Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

Suggested reviewers: Merge Risk: 🟡 Moderate · up to The acceleration skill can miss stale repository references, modify files during architectures that should be report-only, and produce ambiguous precision guidance when all benchmarks fail. These behaviors can lead to unintended repository changes or inconsistent generated ports, so the PR needs fixes or explicit owner acceptance before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Inline comments:
In @.pre-commit-config.yaml:
- Around line 25-26: Update the pre-commit hook configuration around the skill
Markdown files pattern so the validator also runs when referenced paths under
models/, recipes/, ci/, docs/, or interpretability/ change, including deletions
and moves. When triggered by non-skill files, set pass_filenames to false so the
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
tests/conftest.py template to the generated target-root conftest.py when that
file exists. Ensure tests.common.fixtures remains registered at the root level
and is not emitted in the non-top-level tests/conftest.py.
In `@skills/bionemo-recipes-acceleration/assets/parity_check.py.tmpl`:
- Line 17: Update the generated template headers to use the existing skill name
bionemo-recipes-acceleration instead of accelerate-with-bionemo. Apply this
change in parity_check.py.tmpl, conftest.py.tmpl, and
test_modeling_ported.py.tmpl at lines 17; no other template changes are needed.
- 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.
In `@skills/bionemo-recipes-acceleration/scripts/run_gemm_benchmark.py`:
- 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
formatter output in the file so pre-commit checks pass.
- Around line 161-166: Make Phase 0 inventory and .gitignore writes conditional
on successful matching, so hard-stop exits remain side-effect free and only
produce ACCELERATION_REPORT.md. Update the Phase 0 workflow and hard-stop
contract consistently, preserving inventory collection for runs that proceed to
Phase 1.
- Around line 233-236: Update the Phase 5 validation condition so every port
with THD packing enabled generates and runs Tier 2 parity validation, including
Depth A ports without a converter; retain the existing converter-based condition
for non-packing cases, or add the required packing-specific parity test.
- 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.

- Fix SRC-4 violations in bionemo-phage-generation/SKILL.md: prefix bare recipes/evo2_phage_gen/ paths with $BIONEMO_RECIPES/ so they pass the check_skill_references hook (which only existed after this branch added it) - Apply ruff-format alignment fix to probe_hardware.py (trailing whitespace in inline comment) Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
…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. Expand the condition to include any port where packing was applied; Depth A ports without a converter use the no-HF-counterpart path (identity converters, skip conversion tests, checked-in baseline). Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
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.

…ity template Module-level construction of recipe objects and direct attribute lookup of TE support functions crashed at collection time on partial or older TE installs, blocking unrelated BF16 parity tests from running. Replace the static lists/dicts with _build_recipes() and _build_support_checks() that use getattr(..., None) fallbacks: a missing class or support function makes that recipe unsupported rather than raising. NVFP4 determinism kwargs are still passed when the constructor accepts them; a TypeError falls back to no-kwargs. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
All three generated-file headers referenced the non-existent skill name accelerate-with-bionemo; the actual skill directory is bionemo-recipes-acceleration. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
pytest_plugins in non-root conftest (#1): conftest.py.tmpl now targets <target>/conftest.py (repo root) instead of <target>/tests/conftest.py. pytest >= 7 raises a collection error when pytest_plugins is declared in a subdirectory conftest. Updated SKILL.md templates section, output table, Phase 5 instruction, and validation.md wire-conftest section to match. Megatron route overspecification (#10): "Do NOT trigger on: Megatron-LM" now names both evo2_megatron (sequence/genomics) and eden_megatron (protein/chemistry) so the routing guidance is accurate. ImportError too narrow in probe_hardware.py (#12): probe_transformer_engine catches (ImportError, OSError, RuntimeError) so native library load failures surface as ENV_ rather than crashing the probe with an uncaught exception.

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.
