• Other (catalog change, README fix, infrastructure, etc.)

All PRs

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

Other context

Refreshes the nvidia-skills plugin listing and bumps it to 1.4.0.

The only hand-edited file is plugins.d/nvidia-skills.yml. The three plugin.json
manifests and three marketplace.json registries are regenerated output from
.github/scripts/build-plugins.sh — please review the YAML and treat the rest as build
artifacts.

What changed

Field	Before	After
version	1.3.0	1.4.0
display_name	NVIDIA	NVIDIA Skills
description	"Skills for NVIDIAs ecosystem spans GPU acceleration…"	"Find the right NVIDIA skill for GPU acceleration, CUDA, AI agents, data loading, training, inference, robotics, Physical AI, Omniverse, simulation, and other NVIDIA-powered workflows."
short_description	"Guided help for NVIDIA AI, GPU, robotics, simulation, and 3D workflows."	"Find the right NVIDIA skill"
long_description	as above (reworded).	Find and install the right NVIDIA skill for work across GPU acceleration, CUDA, AI agents, data loading, training, inference, robotics, Physical AI, Omniverse, simulation, and more. The plugin checks NVIDIA's live skills catalog, recommends the best match, and provides an install command and a useful first prompt.
category	Coding	Developer Tools
logo / composer_icon	512x428	512x512 (square)
website_url / privacy_policy_url / terms_of_service_url	absent	added
default_prompts	3 prompts, inconsistent punctuation	same 3, phrased as questions

The old description had a couple of copy problems worth fixing before it goes any further
into third-party marketplaces: a missing apostrophe in "NVIDIAs" and a subject/verb
disagreement in "Skills for … ecosystem spans". It also led with the ecosystem rather than
with what the plugin does for you.

display_name becomes "NVIDIA Skills" so the picker distinguishes this plugin from NVIDIA
as the publisher — several surfaces show the publisher name next to the plugin name, and
"NVIDIA / NVIDIA" reads oddly.

Why the version bump matters

Because our plugin.json has pinned 1.3.0 this whole time, the nightly SHA bumps in
anthropics/claude-plugins-official have been advancing the pin without delivering
anything to users already installed at 1.3.0. That includes the DOCA routing work merged
in #379 — see the diff, which changed
nvidia-skill-finder's taxonomy but not the plugin version. This bump is what actually
ships those changes to existing installs.

Going out as 1.4.0 rather than a patch: this repo reserves patch bumps for the automated
chore: sync skills commits and uses minor bumps for deliberate changes to what the plugin
is or ships (1.1.0 swapped the cuOpt skill, 1.2.0 consolidated it, 1.3.0 moved to
discovery-first). A display-name change, new listing copy, new category, new logo, and
newly-delivered routing taxonomy belong in the latter group.

Follow-up

Once this merges, I'll file an issue against anthropics/claude-plugins-official asking
them to refresh the description and homepage on our marketplace entry. Their nightly
job only rewrites source.sha, and for strict: true entries the inline marketplace
description takes precedence over ours — so the stale text there can't be fixed from
this repo.

Validation

• .github/scripts/build-plugins.sh runs clean; regenerated tree matches this diff with no
  stray adds or deletes.
• No SKILL.md or other signed skill content is touched, but require-nvskills-ci watches
  every path under plugins/, so this PR still needs a /nvskills-ci run (triggered below).
  Pushed as an in-repo branch rather than from my fork for that reason.

Reviewed as a catalog/infrastructure change. Approving.

Verified locally against the branch:

• .github/scripts/build-plugins.sh reproduces the committed tree byte-for-byte — the six generated manifests are clean build output.
• Logo is 512x512.
• All three new listing URLs return 200.
• The plugin's bundled nvidia-skill-finder copy matches the catalog copy and includes the DOCA routing taxonomy, so the bump ships real content.
• plugins.d/nvidia-skills.yml was last touched on 2026-07-15 at 1.3.0; #379 merged 2026-07-24 without touching it. The version-pin explanation checks out.
• DCO and author affiliation clean on both commits; all CI green including content-integrity.

The field distribution across manifests looks lopsided at first read but is correct — short_description, long_description, category, and the URL fields only map into the Codex interface block per build-plugins.py.

Two cosmetic notes, neither worth another push: the branch name still says 1.3.1, and the third default prompt is an imperative rather than a question as the description implies.
