Bot review (gpt-6-astra) — DM the bot to share feedback.
Comment: the new MRCR behavior still conflicts with instructions in the skill entry point and shared reference.
Needs action:
- Reconcile MRCR canary guidance in
SKILL.mdandreferences/gym.mdwith the newly forwardedlimit_samples; see inline comment. - Scope the 1M serving instructions in
SKILL.mdto that variant and document the 128K serving adjustment; see inline comment. - Add regression coverage for rendering
example_mrcr.yamlwith null and numericlimit_samples, checking that++limitis respectively omitted or emitted.
No action needed:
- The design reuses existing templates and launcher paths. The PR explains why the upstream condensed schema needs additional bootstrap and why nel-next cannot use OmegaConf environment syntax.
- The reported end-to-end campaigns are useful validation; no existing tests were weakened.

Bot comment.
The new template forwarding makes this guidance correct, but the mandatory reading still says the opposite: SKILL.md MRCR step 6 says limit_samples is inert on the gym path, and references/gym.md's launcher-pin procedure says it does not reach Gym and instructs users to edit collect_rollout_params. The PR body acknowledges this, but it is directly part of the behavior changed here rather than an unrelated follow-up. Update both to describe the MRCR forwarding and link to this canary procedure, so an agent does not bypass the newly supported limiter.
There was a problem hiding this comment.
Addressed in d49cc63: SKILL.md step 6 now says the MRCR template forwards limit_samples as ++limit, pointing to the recipe's Canary section. references/gym.md now says the launcher-level limit_samples reaches the gym only when the template gates it (as example_mrcr.yaml does), and otherwise to add ++limit=N.

Bot comment.
The new largest-supported-variant rule permits 128K, but MRCR step 5 below still unconditionally prescribes --max-model-len 1100000 plus VLLM_ALLOW_LONG_MAX_MODEL_LEN=1. Following the entry point literally therefore retains the 1M serving envelope even after selecting 128K for a 262K checkpoint. Qualify step 5 as 1M-only and document the corresponding 128K serving setup (within trained context, with answer headroom and without the extrapolation override), rather than only changing the two dataset selectors.
There was a problem hiding this comment.
Addressed in d49cc63: SKILL.md step 5 now applies --max-model-len 1100000 + VLLM_ALLOW_LONG_MAX_MODEL_LEN=1 to 1M only. For 128K it says to serve at the trained context, leave answer headroom above 131,072 and skip the override. The recipe's serving section and the template comment say the same.
…t_samples - SKILL.md step 5 and the MRCR recipe/template: the 1100000 max-model-len + VLLM_ALLOW_LONG_MAX_MODEL_LEN envelope is 1M-only; 128K serves at the checkpoint's trained context without the override. - SKILL.md step 6 and references/gym.md: limit_samples is forwarded as ++limit by the MRCR template, no longer "inert". - Add a stdlib-only regression test that example_mrcr.yaml omits ++limit for limit_samples: null and emits ++limit=N otherwise (plus a real Jinja render when jinja2 is available).

Bot review (gpt-6-astra) — DM the bot to share feedback.
Comment: prior concerns are resolved, but the new inline comment in MRCR’s folded deployment command disables subsequent serving flags.
Needs action:
- Move the variant note above
deployment.commandinrecipes/examples/gym/example_mrcr.yaml; see inline comment. - Add a regression in
evaluation/tests/test_example_mrcr.pyverifying the folded deployment command preserves the KV-cache, reasoning-parser, and batching arguments when interpreted by the shell.
No action needed:
- ✔️ Resolved since the last review: canary guidance, variant-specific serving guidance, limit-forwarding coverage, and the MLflow tag concern (the reply distinguishes the upstream tag from its container-pin variable).
- The design retains existing templates and launcher paths; the PR explains the explicit-versus-condensed schema and environment-syntax choices.
- No existing tests were weakened. The new test header matches
LICENSE_HEADER.

Bot comment.
deployment.command is a YAML folded scalar (>-), so this # is command text, not a YAML comment. All following lines fold onto the same shell line: the shell comments out --kv-cache-dtype fp8, --reasoning-parser, prefix-caching and batching settings. This changes the intended serving configuration and can prevent the long-context deployment from fitting. Move this variant note outside the scalar, above command:, and add a regression checking that the folded command retains its trailing flags under shell parsing.
There was a problem hiding this comment.
Good catch, fixed in 6727bef. The 1M-only note is now in the comment block above command:, with a warning that # inside the folded scalar becomes shell text. tests/test_example_mrcr.py adds test_deployment_command_keeps_all_flags_under_shell_parsing, which folds the command, checks that shlex.split(..., comments=True) equals the comment-free split, and checks that --kv-cache-dtype, --reasoning-parser, --enable-prefix-caching, --enable-chunked-prefill and --max-num-batched-tokens are present. Re-adding the inline comment makes it fail.
The 1M-only note added in d49cc63 sat inside the folded `command: >-` scalar, so `#` became shell text and commented out every later flag (--kv-cache-dtype, --reasoning-parser, prefix caching, chunked prefill, --max-num-batched-tokens). Move the note above `command:` and add a regression test that the folded command shell-parses with no comment and keeps those flags.

Bot review (gpt-6-astra) — DM the bot to share feedback.
Approve: prior concerns are resolved, including the folded-command bug and regression coverage; canary guidance, variant-specific serving, and MLflow tag documentation are consistent.
No action needed.
Large PR: spans 7 directories (≥ 5). The review came back clean, so this is an LGTM — a human should take the final look and approve.

What does this PR do?
Type of change: documentation (agent skill) + one template bug fix
Aligns the
evaluationskill's three upstream-tracked benchmarks (Terminal-Bench 2.1,SWE-bench Verified, MRCR) with the current
nvidia-eval-factory-benchmarkingconfigs, andfixes guidance that turned out to be wrong when a full three-benchmark campaign was run with
the skill end to end. Rebased on #2499. The first commit is the alignment; the other two
address review (MRCR serving scoped per variant,
limit_samplescanary guidance, andregression tests for the template's
++limitgate and its folded serve command). The skill text keeps only the rules; the evidence behind them is below.GDPVal is out of scope. It was removed from this skill in #2470, and this PR replaces #2464.
Alignment with upstream
HARBOR_ECS_REGION. TB2.1's ECR repo name tracks the region;SWE-bench's stays in us-west-2.
http_pairs_dumplast. Upstreamis split on its position, which changes only what the dump records, never the score.
Interceptor lists replace wholesale on merge, so a leaf must restate the whole chain.
capture_request_bodygoes on the service. A shared block injects an alias-only entry withno
type.task_nameandnemo-evaluator-next-version.max_concurrent: 50 for nano-class models, 15 for larger ones (all upstream non-nanoleaves override it to 15).
proxy.request_timeoutmust always be set explicitly. Otherwise it inherits the modelfragment's serving value, which ranges from 3600 to 36000 upstream, and TB2.1 has no
benchmark key for it.
