### Step 1 — Prerequisites

Run `nel --version`; if missing, instruct `pip install nemo-evaluator-launcher`. If user has an existing config, skip to Step 8 (optionally review for `???` and quantization flags first).
Run **`"$SKILL_DIR/scripts/nel-check.sh"`** — it asserts the `nel` on PATH is the validated launcher and, when it is not, prints the exact `pip install` command to fix it. Do **not** just check that `nel` exists: a base environment can already carry an older launcher (directly, or via `nemo-evaluator-launcher-internal`, which ships its own launcher version), and scoring on it silently makes the run non-comparable with runs on the validated one. Record the version line it prints with the scores (Step 9). See `references/launcher-version.md` for why it is pinned and how to bump it. If user has an existing config, skip to Step 8 (optionally review for `???` and quantization flags first).

**Set up `.env` now (not Step 8).** The working `.env` lives at the **workspace root** — the directory you run `nel` from — matching `modelopttools:eval-config`'s convention; do **not** create it under the skill dir. (NEL does not discover `.env` by path: it reads secrets from the shell env via the `host:` prefix after you `source`, so the location is purely *which file you source* before `nel run`. Keeping the single `.env` at the workspace root avoids a stale duplicate under the symlinked, shared `.agents/` skill tree.) For judge-scored / user-sim tasks (HLE, AA-LCR, Tau2), seed it from the template if absent — the template ships under the skill dir, the working `.env` does not: `[ -f .env ] || cp "$SKILL_DIR/recipes/env.example" .env`. Then try `modelopttools:eval-config` (if available) to fill the judge `model_id`/`url` rows (user adds the secret key). Needed before Step 5, which substitutes those values into task `<VAR>` placeholders.

In the context of the NVIDIA Model Optimizer, this skill is used for managing and running LLM evaluations [1][4]. It includes instructions for handling different evaluation workflows, such as standard evaluations using the nemo-evaluator-launcher [1][5] and specialized agentic benchmarks (AA benchmarks) that require the nel-next (nemo-evaluator 0.3.x) framework [1][2]. 2. nel-check.sh: While not a standard, globally defined tool name, in this repository ecosystem, it (often referred to as nel-next.sh) is a helper script used for environment management and execution of the nel-next evaluation pipeline [1][2]. For instance, it is used to perform isolated setups of the 0.3.x virtual environment, run evaluations (via nel-next.sh eval run), and manage artifact pushing to MLflow [1][4][2]. In summary, these files are part of the NVIDIA Model Optimizer's automation suite for benchmarking models, where the SKILL.md provides the procedural instructions for an AI agent to perform evaluations, and nel-next.sh (likely the script you are referring to as nel-check.sh) provides the underlying execution logic for newer evaluation types [1][2].

Record the successful pre-run validation result, not the current configured pin.

nel-check.sh --version only prints NEL_VALIDATED_VERSION. It does not identify the launcher that executed an already completed run. If the pin changes between execution and reporting, these instructions can record the new pin for an older run and make mismatched baseline and candidate runs appear comparable.

## Updating the launcher pin

When a newer `nemo-evaluator-launcher` release is available:

1. Review its release notes for launcher schema, generated Slurm, resume, and export
changes.
2. Update `NEL_GDPVAL_VERSION` in `scripts/nel-gdpval.sh` and the expected spec in
`tests/test_nel_gdpval.py`.
3. Run the focused test and pre-commit checks. Verify `nel-gdpval.sh --version`
reports the candidate version.
4. Dry-run a known GDPVal config and confirm the literal `NEL_INVOCATION_ID`
The pin itself lives in `scripts/nel-validated-version.sh` (shared with the Step 1
gate), and the general bump procedure is in `references/launcher-version.md`.
GDPVal adds two requirements to it, because this is the one config that forwards
`runtime:NEL_INVOCATION_ID`:

1. Dry-run a known GDPVal config and confirm the literal `NEL_INVOCATION_ID`
assignment still precedes its runtime re-export in every generated `run.sub`.
5. Launch with the candidate version and monitor the first 20–30 minutes for SIF
2. Launch with the candidate version and monitor the first 20–30 minutes for SIF
sandbox startup and judge authentication. GDPVal ignores `limit_samples`, so
there is no cheap reduced-sample canary.

Only then update the validated version used for scored runs. Do not mix launcher
versions within a baseline-versus-candidate comparison.

# Launcher version — the validated `nemo-evaluator-launcher` pin

Shared reference for the **0.2.x path** (Steps 1–9, including GDPVal). nel-next
(`nemo-evaluator` 0.4.x) is a different package and pins separately — see
`references/nel-next.md`.

The validated version lives in one place, `scripts/nel-validated-version.sh`, and
is consumed by `scripts/nel-check.sh` (Step 1 gate) and `scripts/nel-gdpval.sh`
(GDPVal's hard pin). Bump that one file, not the call sites.

## Why the version is pinned

**Comparability.** This skill exists to produce baseline-vs-candidate deltas.
Running the two legs on different launchers folds a harness change into the
measured model delta — the same reasoning `nel-next.sh` already applies to its
0.4.x git SHA. Keep a comparison pair on one launcher, and record the version
with the scores.

**A known failure, on GDPVal specifically.** Launchers older than the pin emit
`export NEL_INVOCATION_ID="${NEL_INVOCATION_ID}"` into the generated `run.sub`
without assigning it first, so the job exits with `NEL_INVOCATION_ID: unbound
variable` under `set -u` before the evaluation client starts. This fires only for
configs that forward `runtime:NEL_INVOCATION_ID`, which today is GDPVal alone —
so it is a GDPVal correctness requirement, while comparability applies to every
scored task. Details and the dry-run check: `references/gym-gdpval.md`.

## Presence is not the same as version

Step 1 used to accept any `nel` already on PATH. That is how a GDPVal run picked
up a stale 0.2.4 from the base environment and failed. Note that
`nemo-evaluator-launcher-internal` ships its **own** launcher version and can
supply an older `nel` even when it is itself newer — `nel --version` prints both
rows, and only the `nemo_evaluator_launcher` row governs generated-Slurm and
schema behavior:

```text
nemo_evaluator_launcher: 0.2.4 <- this row gates
nemo_evaluator_launcher_internal: 0.3.174+20260609
```

Run the gate rather than eyeballing it:

```bash
"$SKILL_DIR/scripts/nel-check.sh" # exits non-zero with the pip command to fix it
```

`NEL_ALLOW_UNVALIDATED=1` downgrades a mismatch to a warning and marks the output
`(UNVALIDATED)` — dev/canary only, never for scored or compared runs. GDPVal has
no escape hatch: it runs through `nel-gdpval.sh`, which hard-pins the launcher.

## Updating the pin

When a newer `nemo-evaluator-launcher` release is available:

1. Review its release notes for launcher schema, generated Slurm, resume, and
export changes.
2. Update `NEL_VALIDATED_VERSION` in `scripts/nel-validated-version.sh`, and the
expected version in `tests/test_nel_check.py` / `tests/test_nel_gdpval.py`.
3. Run the focused tests and pre-commit checks, and confirm `nel-check.sh
--version` and `nel-gdpval.sh --version` both report the candidate.
4. Re-validate on a real run before adopting it for scored work — for GDPVal,
follow the extra dry-run and canary steps in `references/gym-gdpval.md`
(`limit_samples` is inert there, so there is no cheap reduced-sample canary).
5. Do not mix launcher versions within a baseline-versus-candidate comparison. If
the baseline was scored on the old pin, either keep the candidate there too or
re-run the baseline on the new one.

# Single source of truth for the validated `nemo-evaluator-launcher` (the 0.2.x
# path — Steps 1-9 and GDPVal). Sourced by `nel-check.sh` and `nel-gdpval.sh` so
# one edit bumps both; see references/launcher-version.md before changing it.
#
# Assigned unconditionally, never from the environment: a stale ambient value
# (e.g. sourced from `.env`) must not be able to select a different launcher.
# nel-next (`nemo-evaluator` 0.4.x) is a different package and pins separately in
# nel-next.sh.
