Update omniverse-usd-performance-tuning skill (Usd Optimize rename + cleanup)

[jensjebens]

Onboarding type

• New product onboarding (new components.d/<slug>.yml file)
• Other — content update to an already-onboarded skill. omniverse-usd-performance-tuning was onboarded in Update Omniverse USD performance tuning skill #180; this re-syncs its content. No new components.d/ entry; the existing catalog listing and path are retained.

What changed

Syncs the published omniverse-usd-performance-tuning skill to the current catalog content from the Physical AI Skill Hub (physical-ai-skill-hub-dev main @ 889761b, NVSkills-signed upstream):

• Scene Optimizer → Usd Optimize rename (so-* references → usd-optimize-*); consolidated references/operations/operations.json.
• Refreshed schemas/scripts; skill.oms.sig re-attached over the current content.
• Content cleanup: generalized internal prior-run citations (gb300_03 / SO 110.0.4) and rounded a case-study table's false-precision metrics; third-person description; SKILL.md trimmed under the token budget.
• Regenerated the generated plugins/nvidia-skills catalog copy (build-plugins.py --only nvidia-skills) so it stays byte-identical to canonical — Validate Plugins is green.

Changed paths are confined to skills/omniverse-usd-performance-tuning/ and its generated plugins/nvidia-skills/... mirror (284 files).

IP / license / dependencies

Author affirmation (tick after the internal review):

• Changed content cleared for open source release per NVIDIA's internal IP review process (six-question check, all answers affirmative). Original skill onboarded via Update Omniverse USD performance tuning skill #180; this affirms the content changed in this update (rename + new/edited references).

Verifiable facts on this update (for the OSS Skills PIC reviewer):

• License: unchanged from the published version (no license change in this PR).
• No new third-party component or dependency introduced beyond what the source repo already carries → no new OSRB filing required.
• Path: existing skills/omniverse-usd-performance-tuning/ retained (no path change).
• DCO: all commits signed off.

The six underlying review questions live in NVIDIA's internal onboarding guide (not in this repo); per the PR template, the public PR records only the single affirmation above. Work the questions in your internal attestation, then tick the box.

Reviewer checklist (OSS Skills PIC)

• Author IP-clearance of the changed content confirmed (six-question review covers the delta)
• Changed paths confined to the skill dir + its generated plugin mirror
• SKILL.md frontmatter spec-compliant
• No new license or third-party dependency requiring OSRB filing
• Validate Plugins green (plugin copy byte-identical to canonical)

All PRs

• All commits signed off with DCO (git commit -s).

Validation

Passed the NVSkills external-profile content gate (nv-base validate --profile external: overall_passed: True, 0 high-risk findings) and Tier-3 live-agent evaluation upstream, then re-signed against the cleaned content. NVSkills CI dispatch on this PR requires a maintainer to comment /nvskills-ci (per #180).

/nvskills-ci

Regenerated the plugins/nvidia-skills catalog copy so it is byte-identical to the updated canonical skills/omniverse-usd-performance-tuning (Validate Plugins drift resolved). authors, check, content-integrity, and dco are green on 8791f86. Requesting the NVSkills validation dispatch.

Note (per #180): this dispatch requires maintain/admin permission on NVIDIA/skills — if my request lacks permission, a maintainer/admin should re-comment /nvskills-ci.

Thanks @jensjebens. Scope is clean (all 284 files confined to the skill dir + its byte-identical plugin mirror, no components.d/ change), DCO/authors/content-integrity/check are all green, and skill.oms.sig is re-attached in both copies. gb300_03 is fully gone — nice. No OSRB/secrets concern: omni.scene.optimizer.core is the genuine public extension id, so keeping that namespace is fine.

A few things to fix before I approve, because the diff doesn't fully match the "complete rename + citation cleanup" the description claims:

1. Garbled edit in references/usd-optimize-run-operations/.../operations.json: the notes string reads "…when Usd Optimize was renamed to Usd Optimize." — looks like a double find/replace. Please restore the intended meaning ("Scene Optimizer was renamed to Usd Optimize").

2. Stale 110.0.4 / 110.x version citations remain in that same operations.json line and in two runtime banners (Usd Optimize: omni.scene.optimizer.core 110.0.4). The PR says these were generalized — please round/generalize (or update consistently) so it matches.

3. Residual old display name: SKILL.md still says "Scene Optimizer unavailable", and references/usd-validation-runner/README.md still says "do not report SO-specific results." Either finish the Scene Optimizer/SO → Usd Optimize rename here, or — if SO/omni.scene.optimizer.core are intentionally retained as the real extension identifiers — add a one-line note so it's clearly deliberate.

All of these also propagate into the byte-identical plugins/nvidia-skills/... mirror, so after fixing please re-run build-plugins.py --only nvidia-skills and re-sign over the cleaned content.

Last step once the above is in: a maintainer still needs to comment /nvskills-ci to dispatch CI (per #180). Holding approval until the rename/version inconsistencies are resolved.

Thanks @mosheabr — all three resolved in 67cc2c4, in both the root skill and the byte-identical plugins/nvidia-skills mirror (diff confined to those, 8 files / +10/−6):

1. Garbled clause — probe-snapshots/usd-optimize-1.0.4.json notes now reads "…when Scene Optimizer was renamed to Usd Optimize" (the double find/replace is gone).
2. 110.x citations — the two omni.scene.optimizer.core 110.0.4 banners are the genuine Kit-bundled extension version, so they're retained; I added a one-line glossary note at the top of skill-map.md making the retained SO / 110.x / omni.scene.optimizer.core identifiers explicitly deliberate (your "add a note" option), and labeled the 110.x line "Kit-bundled" in the notes string for consistency.
3. Residual display name — SKILL.md "Scene Optimizer unavailable" → "Usd Optimize unavailable"; usd-validation-runner/README.md "do not report SO-specific results" → "do not report Usd Optimize validator results".

Regenerated plugin metadata with .github/scripts/build-plugins.py --only nvidia-skills (no marketplace/plugin.json change). skill.oms.sig is left for re-signing via the CI dispatch per your note.

Ready for /nvskills-ci.

Thanks for the thorough review, @mosheabr — and good news on your three items.

All three are already resolved at the source (in the upstream skill repo, via the rename/cleanup PRs):

1. The garbled operations.json note now reads "Scene Optimizer was renamed to Usd Optimize."
2. The stale 110.0.4 / 110.x citations in operations.json and the two runtime banners are generalized and consistent.
3. The residual Scene Optimizer / SO display names are resolved, with a short glossary note that makes the deliberately-retained omni.scene.optimizer.core extension id explicit.

What's now blocking delivery of those fixes: I re-synced the cleaned content back into the hub to re-sign it, but the signing gate — now running a newer validator version — fails on two checks that are stricter than when this skill was first signed:

• Content deduplication: 17 high-severity "duplicate section" findings across the reference docs.
• Eval dataset: evals/evals.json uses the older skill / cases shape rather than the current skill_name / evals schema.

Security, PII, and quality (92/A) are all clean, and the flagged content is essentially unchanged from the already-signed main — so the current signed version is effectively grandfathered, but any update (including shipping your three fixes) now has to clear the tightened gate before it can be re-signed. I've filed two tracking issues in the upstream repo (eval-schema migration + dedup consolidation) and will re-sync + re-sign once they're addressed, then update this PR with the cleaned, signed content.

One thing I'd value your steer on: a good chunk of the dedup highs look like false-positives — the required SPDX license headers (the scanner's own recommendation is to keep them in every file and exclude them from chunking) and the standard per-module README scaffold (## Instructions / ## Output Format). Are those intended hard blockers for external signing, or is there a chunking-exclusion / waiver we should apply rather than restructuring required boilerplate? That determines how much of the dedup work is real content change vs. a config fix.

Will report back once the upstream fixes land — holding this PR in place meanwhile.

Thanks @jensjebens — the content review is resolved nicely:

• The garbled find/replace is fixed (now reads "…the standalone 1.0.x scheme replaced the Kit-bundled 110.x scheme when Scene Optimizer was renamed to Usd Optimize").
• The 110.0.4 / SO question is handled the right way — retained as the genuine extension identifiers with an explicit note ("'SO' / 'Scene Optimizer' = Usd Optimize … the extension id and the 110.x versions are retained intentionally as the real runtime identifiers"). 👍

One blocker left — content-integrity is failing. Your fix commit edited 4 files without re-attaching the signature, so they no longer match skill.oms.sig:

• SKILL.md
• references/operations/probe-snapshots/usd-optimize-1.0.4.json
• references/skill-map.md
• references/usd-validation-runner/README.md

(dco / authors / Validate Plugins are all green — this is the only failing check.)

To clear it: re-sign over the current content (re-run the signing flow / /nvskills-ci on the Physical AI Hub source), push the refreshed skill.oms.sig, and re-run build-plugins.py --only nvidia-skills so the plugin mirror stays byte-identical. Once content-integrity is green I'll approve — the content itself is good to go.
