Summary

Post-merge follow-up to #13557. That PR added the performance optimization skill pack; a review after merge (review) surfaced 13 findings. This PR fixes only the ones with an unambiguous mechanical correction. The four that need an author decision on intent, and the two stale Sigstore bundles, are deliberately left out and tracked below.

Linear: OPS-8324

Fixed

Finding Fix
kubernetes-recipe-workflow.md reverts the RBAC hardening from #13557's own final commit 7e14ea4 Adopt the tolerant CRD gate from deploy-dynamo-recipe/SKILL.md:84-95. The guide kept get crd | grep -i dynamo || exit 1, so a namespace-scoped identity aborted with a false Dynamo CRDs missing; get storageclass / get nodes are advisory here now too
One kubectl get svc in the same guide omits --context Pin it, per the invariant deploy-dynamo-recipe/SKILL.md:98 states
deploy-dynamo-recipe/SKILL.md unconditionally applies model-download.yaml under set -euo pipefail recipes/deepseek-v4/{flash,pro} ship model-download-fp8.yaml / model-download-nvfp4.yaml, so the literal path never resolved and aborted the whole deployment. Download and validate manifests are now both optional and named from the handoff
agent-skills/overview.mdx links pinned to 3e522d8e #13557 was squash-merged, so that SHA is not an ancestor of main — a dangling object that also predates the branch's own hardening commits. The paths resolve on main now, which is the reason the pin existed
kimi-k2.5 feature-benchmark page still documents the old duration #13557 moved BENCHMARK_DURATION 3600 → 1800 in all four perf.yaml files and added a requalification caveat to the recipe README, but not to the published page. Sync the workload line and the aiperf command, and carry the caveat over
vllm.md sizing relation max_num_batched_tokens ≈ max_num_seqs × avg_seq_len Conflates the per-step token budget with total KV capacity — ~1M batched tokens at 256×4096, exactly the oversized budget the neighbouring bullet warns will OOM or hurt TTFT. Replaced with per-step guidance. Also repairs a garbled sentence in the chunked-prefill bullet
SPDX header missing on 15 files #13557 added Added, placed after the frontmatter as the other skills do

Deliberately not fixed here

Left open on the #13557 thread because they need the author's call, not a mechanical edit:

  • concurrency-grid.md:17already fixed in feat(skills): baseline authoring and recipe confirmation when the user has no existing DGD #13625 by feab9402c9, ~10 hours before my review. The author kept the AT MOST 4x cap, corrected the example to 16, and added a >= concurrency floor — the opposite resolution from the one I inferred, and a better one. Nothing needed here.
  • run-aiperf-benchmark / run-artifacts.md — fixed artifact paths plus a never-overwrite rule plus mandatory n=3 repeats in one DEPLOY_ROOT is unsatisfiable. Needs a per-run layout decision that spans both files.
  • optimize-loop.md:193 — GPU-hours derived from benchmark duration alone, excluding the download/validate/readiness window the GPUs are held for, so BUDGET_STOP under-counts. The fix needs new timestamps in deployment_ledger.json.
  • parallelism.md:45 — "no need to benchmark multiple replicas" authorizes the unmeasured fleet projection comparison-uncertainty.md forbids.
  • dynamo-router-starter and dynamo-interconnect-check skill.oms.sig — both bundles now fail verification (3 and 2 digest mismatches). These are the only two signed skills in the repo; re-signing needs a maintainer /nvskills-ci run.
  • ${DEPLOY_ROOT}/smoke/ is an artifact directory run-artifacts.md neither declares nor permits.

Validation

Docs and agent-instruction files only — no runtime code paths change.

  • pre-commit run --files <the 19 changed files> — all applicable hooks pass (codespell, check-yaml, trim trailing whitespace, mixed line ending, Check docs asset paths are ones Fern rewrites, Validate .agents/skills SKILL.md frontmatter and AGENTS.md index)
  • python scripts/validate_skills.pyvalidated 25 skills: OK
  • Every claim above re-verified against origin/main at d91b99c rather than the PR diff: recipes/deepseek-v4/*/model-cache/ file listings, the squash-merge parentage of 341f9ac, and the decoded per-file digests in both skill.oms.sig DSSE payloads
  • Admonition syntax follows the style guide (Fern <Warning> in .mdx)
  • SPDX placement follows the SKILL.md convention: the block sits below the H1, as in all 15 skills that already carry one. (For a .md with frontmatter the repo has two forms and neither can be at line 1, since the frontmatter opens there: 217 files — essentially all of docs/fern/ — put it inside the frontmatter as # YAML comments, and 15 put it below the H1. These are agent-instruction files, not Fern pages. Neither form is CI-enforced: .md is in ignored_types in .github/workflows/copyright-check.ps1, which makes that script's own .md matcher unreachable.)

Note: .agents/skills/ changes need a maintainer /nvskills-ci comment, and full CI needs /ok to test <sha>.

…ll pack (OPS-8324)

Post-merge follow-up to #13557. Fixes only the findings with an unambiguous
mechanical correction; the intent-dependent ones and the two stale Sigstore
bundles stay open on the PR thread.

- kubernetes-recipe-workflow.md preflight: adopt the RBAC-tolerant CRD gate
  that #13557's final commit applied to deploy-dynamo-recipe/SKILL.md. The
  guide kept `get crd | grep -i dynamo || exit 1`, so a namespace-scoped
  identity aborted with a false "Dynamo CRDs missing"; `get storageclass` and
  `get nodes` are now advisory here too, matching the skill.
- kubernetes-recipe-workflow.md: pin `--context` on the one `kubectl get svc`
  that omitted it, per the invariant deploy-dynamo-recipe/SKILL.md states.
- deploy-dynamo-recipe/SKILL.md: stop assuming the literal filename
  `model-download.yaml`. recipes/deepseek-v4/{flash,pro} ship
  model-download-fp8.yaml and model-download-nvfp4.yaml, so the unconditional
  apply aborted the whole deployment under `set -euo pipefail`. Download and
  validate manifests are now both optional and named by the handoff.
- agent-skills/overview.mdx: point the two agent-docs links at `main`. #13557
  was squash-merged, so the pinned 3e522d8 is not an ancestor of main -- it
  is a dangling object that also predates the branch's own hardening commits.
  The paths resolve on main now, which is why the pin existed.
- kimi-k2.5 feature-benchmark page: the four perf.yaml manifests moved
  BENCHMARK_DURATION 3600 -> 1800 in #13557 but this page was not updated.
  Sync the workload line and the aiperf command, and carry over the
  requalification caveat the recipe README already has.
- vllm.md: drop `max_num_batched_tokens ~= max_num_seqs * avg_seq_len`. That
  conflates the per-step token budget with total KV capacity and yields ~1M
  batched tokens at 256x4096 -- the oversized budget the same bullet's
  neighbour warns will OOM or hurt TTFT. Also repair a garbled sentence in
  the chunked-prefill bullet.
- Add the missing SPDX header to the 15 files #13557 added without one.

The snippet still unconditionally expands optional DOWNLOAD_MANIFEST under set -u, so recipes without a separate download manifest fail before the documented skip behavior can happen. Fix: wrap the download apply/poll block in a guard that only runs when DOWNLOAD_MANIFEST and DOWNLOAD_JOB are set.

🤖 AI Fix

In .agents/skills/deploy-dynamo-recipe/SKILL.md, update the bash block under "Apply support manifests first" so the kubectl apply -f "${DEPLOY_ROOT}/applied_manifests/${DOWNLOAD_MANIFEST}" command and its polling loop are enclosed in if [[ -n "${DOWNLOAD_MANIFEST:-}" && -n "${DOWNLOAD_JOB:-}" ]]; then ... fi, preserving set -euo pipefail.

…ut them

The previous commit inserted the SPDX comment between the YAML frontmatter
and the H1. All 15 SKILL.md files in the repo that already carry SPDX put it
directly below the H1 instead. Match them.

For the record, the repo has two placements for a .md file with frontmatter,
and the block cannot sit at line 1 in either case because the frontmatter
must open there: 217 files (essentially all of docs/fern/) carry it inside
the frontmatter as `#` YAML comments, and 15 -- every SKILL.md that has one
-- carry it below the H1. These are agent-instruction files, not Fern pages,
so they follow SKILL.md.

Neither form is enforced: .md is in `ignored_types` in
.github/workflows/copyright-check.ps1, which makes the `.md` matcher defined
in that same script unreachable.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 20cc9

The updated guidance can still misreport Kubernetes failures, attempt absent optional jobs, and recommend vLLM settings that may fail at startup or degrade performance. These are bounded documentation-driven deployment risks, but follow-up correction or explicit owner acceptance is needed before the PR is merge-ready.

- **`max_num_batched_tokens`** — maximum total tokens admitted per scheduling step, analogous to `max_num_tokens` in

is `max_num_batched_tokens ≈ max_num_seqs × avg_seq_len`.
TensorRT-LLM. Without chunked prefill, the largest prompt must fit within this budget. This is a *per-step* budget,
not total KV capacity: in steady-state decode each running sequence contributes about one token per step, so the
budget only has to cover the decode batch plus one prefill chunk. Start in the low thousands — raise it for
throughput, lower it for TTFT — and size total in-flight tokens with `max_num_seqs` and `max_model_len` instead.

Correct the max_num_batched_tokens tuning guidance.

Describe the workload tradeoff accurately: smaller values can improve ITL, while larger values can improve TTFT and throughput for suitable workloads. Account for reserved speculative-decoding slots when comparing max_num_scheduled_tokens with max_num_batched_tokens, and explicitly state that max_num_batched_tokens must be at least max_model_len when chunked prefill is disabled to avoid an invalid startup configuration.

Thorough review of this - thank you for doing it, and for the discipline of leaving the intent-decisions out. Full verification pass below; net: approve after three changes.

Verified clean (checked against main at 341f9ac and against #13625's branch): the kubernetes-recipe-workflow CRD-gate mirror is byte-identical to the hardened skill block (correctly not a third variant), the --context pin matches the skill's stated invariant, the kimi duration/Warning sync matches all four perf.yamls and the README caveat, the chunked-prefill garble repair is faithful, and the SPDX placements match the 15 skills that already carry headers.

Three changes needed before merge:

  1. vllm.md: "lower it for TTFT" is inverted. A larger max_num_batched_tokens finishes prefill in fewer steps and IMPROVES TTFT; a smaller budget protects decode and improves ITL at TTFT's expense. Should read "lower it for smoother inter-token latency." (Deleting the old formula is right - it conflated per-step budget with KV capacity.)
  2. The sentence "some fold the download into the model-cache manifest" is false on main - all 26 model-cache.yaml files repo-wide are PVC-only, every model-cache/ dir ships a separate download manifest. Appears in both deploy-dynamo-recipe/SKILL.md and kubernetes-recipe-workflow.md. (The adjacent "few ship a validation job" claim is accurate - exactly one does.)
  3. Two author-intent items to settle rather than assume: (a) the manifest-naming mechanism - the original "stable names such as" wording arguably means the copy step NORMALIZES filenames, which already solves the deepseek-v4 fp8/nvfp4 case; your variable-indirection version changes that contract while leaving the stable-names sentence in place. Happy to go either way, but pick one and make the text consistent. (b) the overview.mdx links - agreed the squash orphaned the pin, but floating main discards the pin semantics; re-pinning to 341f9ac96a preserves the original intent.

On your finding #4 (budget under-count): confirmed valid - I initially thought the merged text included deployment hold time; it does not (verified by grep on main). Your deferral is right and we'll take that fix with the ledger-timestamp work.

Sequencing vs #13625: merge-tree shows exactly one conflict between the two (the SPDX block on optimize-loop.md abuts the paragraph #13625 rewrites); the other four shared files auto-merge cleanly. Since #13625 is the substantive rewrite, suggest it lands first and this rebases - the cost is one trivial SPDX re-placement.

Review verified with Claude Code against the live tree; all claims above were checked, not assumed.

Correction to my review above, after re-verification against main: item 3(b) is withdrawn. The pinned commit's agent-docs/ tree is byte-identical to main (git diff <pin> main -- agent-docs/ is empty) and the blob URLs return 200 - the pin postdates all content hardening, so it serves stale content to no one. The right disposition for the overview.mdx links is NO action: drop that hunk entirely rather than retargeting to main or re-pinning.

On SPDX, one clarifying nuance for anyone following along: the six SKILL.md files carry license: frontmatter but no SPDX markers on main, AND .md is exempt from the copyright checker - so the additions here are optional consistency, neither required nor harmful. Author's preference.

Items 1 (TTFT/ITL inversion) and 2 (the model-cache-folding sentence) stand as blocking. The signature-bundle re-sign for the two signed skills is real and we're taking it as a separate follow-up.

Verified with Claude Code; the earlier re-pin recommendation was my error.

… TTFT direction

Review feedback from @BenHamm on #13639 plus two bot findings. Three of my
own defects, one hunk withdrawn.

- Manifest naming: revert the ${DOWNLOAD_MANIFEST}/${VALIDATE_MANIFEST}
  indirection. The pre-existing "with stable names such as" contract already
  means the copy step NORMALIZES filenames, which handles the deepseek-v4
  fp8/nvfp4 case on its own; my version changed that contract while leaving
  the stable-names sentence in place, and expanded the variables bare under
  `set -euo pipefail` so the documented skip aborted with "unbound variable"
  instead. Make the normalization explicit, including selecting the variant
  that matches the assigned DGD, and keep the literal filenames in the apply
  blocks.
- Drop the false claim that some recipes fold the download into the
  model-cache manifest. Verified: all 26 model-cache.yaml are PVC-only and
  every model-cache/ dir ships a separate download manifest. Only the
  filename varies, never the existence.
- vllm.md: "lower it for TTFT" was inverted. A larger per-step budget
  finishes prefill in fewer steps and improves TTFT; a smaller one keeps
  prefill from crowding decode and improves inter-token latency.
- Drop the overview.mdx hunk. The pinned tree is byte-identical to main and
  both URLs return 200; the commit stays reachable via refs/pull/13557/head,
  so the link rot I predicted does not occur. No action was the right call.

Not changed: the CRD gate stays byte-identical to the merged
deploy-dynamo-recipe block. CodeRabbit is right that it cannot distinguish a
Forbidden from a timeout, but that is inherited from #13557 and diverging
here would recreate the third variant this PR exists to remove.

Pushed 57a04c263f. All three blocking items plus both bot findings; one hunk withdrawn. I re-verified each claim against the tree rather than taking them as read.

1. TTFT/ITL inversion — confirmed, my error. Larger per-step budget finishes prefill in fewer steps and improves TTFT; smaller keeps prefill from crowding decode and improves ITL. Now reads:

Start in the low thousands — raise it to finish prefill in fewer steps for throughput and TTFT, lower it to keep prefill from crowding decode for smoother inter-token latency

2. The model-cache-folding sentence — confirmed false, my error. Verified independently: all 26 model-cache.yaml are PVC-only (one carries three PVCs), and every model-cache/ dir ships a separate download manifest. Only the filename varies, never the existence. Removed from both files. My real evidence was always the fp8/nvfp4 filename split; I overstated it into an existence claim I had not checked.

3(a). Manifest naming — took the normalization reading, and it retracts my original finding. You're right that "with stable names such as" already means the copy step normalizes, which handles deepseek-v4 on its own. So there was no bug in the apply block, and my variable indirection changed the contract while leaving the stable-names sentence in place. Reverted to the literal filenames; the copy step now states the normalization explicitly and adds the one thing that reading genuinely needs — selecting the variant matching the assigned DGD's precision before copying it as model-download.yaml. I'll retract finding #9 on the #13557 thread.

This also dissolves both bot findings: @dynamo-review-agent and CodeRabbit independently caught that ${DOWNLOAD_MANIFEST} expanded bare under set -euo pipefail, so the documented skip aborted with unbound variable instead. No new variable now, so nothing to guard.

3(b). Withdrawn — and I owe more of a concession than you took. git diff <pin> main -- agent-docs/ is empty and both URLs return 200, as you said. Beyond that, the commit stays reachable through refs/pull/13557/head, so the "will 404 once the branch is GC'd" risk I gave as the reason doesn't materialise either. The hunk is dropped; the finding was wrong, not merely superseded.

Declined, with reasoning: CodeRabbit wants the CRD gate to distinguish Forbidden from timeouts and discovery errors. That's a fair point about the gate, but it's inherited from the merged deploy-dynamo-recipe block, and this PR exists precisely to stop those two files disagreeing — patching only this copy recreates the third variant you verified was correctly absent. Worth a separate change to both, if you want it.

SPDX: left in, per your "optional consistency, author's preference." Happy to drop the 15-file hunk if you'd rather keep this PR to the behavioural fixes.

Sequencing: agreed — land #13625 first and I'll rebase. With the overview.mdx hunk gone the shared surface is unchanged, so it's still just the one optimize-loop.md SPDX re-placement.

Approving: re-verified the 20:12Z push against the tree. All three blocking items from my review are correctly addressed (TTFT/ITL direction now accurate, the model-cache-manifest claim removed from both files, the overview.mdx link hunk dropped per my correction), and the manifest-naming self-contradiction is resolved via stable-name normalization. The four unresolved bot threads all predate the push and their complaints no longer reproduce on the head; please resolve them. After #13625 (merged just now as 2a6da14) please rebase — that also picks up the #13642 CI coordinator fix your branch predates.
