📝 Walkthrough

Walkthrough

The pull request adds a multi-file NVIDIA Elements agent skill, packages it as an archive, installs it through CLI and MCP flows, and replaces legacy skill discovery with unified installation. It also updates project documentation, site publishing, tests, and build inputs.

Changes

NVIDIA Elements skill

Layer / File(s) Summary
Skill content and references
.agents/skills/elements/*
Adds the Elements skill definition and reference guidance for artifacts, setup, integration, doctor, and migration.
Skill registry and prompts
projects/internals/tools/src/skills/registry.ts, projects/internals/tools/src/skills/*.md, projects/internals/tools/src/skills/index.test.ts
Changes skills to file bundles, registers one elements skill, and retains four reference-backed prompts.
Validation and packaging
projects/internals/tools/src/skills/utils.ts, projects/internals/tools/src/skills/utils.test.ts
Validates bundled files, writes skill directories, and emits deterministic ZIP archives for multi-file skills.
CLI, MCP, and project installation
projects/internals/tools/src/skills/service.ts, projects/cli/src/install.ts, projects/internals/tools/src/project/setup-agent.ts
Replaces skill listing and retrieval with local or global Elements skill installation.
Publishing and documentation
projects/site/src/_11ty/plugins/*, projects/site/src/docs/*, projects/*/README.md, README.md
Publishes the Elements archive and updates CLI, MCP, migration, package, design, and build documentation.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🟡 Moderate · up to d4f71

The skill installation migration has unresolved configuration and test-coverage risks. Cursor users may receive non-working setup guidance, while CLI and tool-removal behavior is not adequately protected by the affected tests.

Warning

Some tools did not complete. Review the errors below.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

ESLint skipped: missing config or dependency (missing-dependency). The ESLint configuration references a package that is not available in the sandbox.

This moves the packaged skill from the CLI to the root of the repo to enable more third party tool discoverability. The content itself remains mostly unchanged.

Rather than have multiple small elements related skills, this combines into a single elements skill with included references. This simplifies the distribution and agent choice.

Singular skill with packaged references simplifies the tooling to only need to install vs having to choose.

The build still preserves/supports the mcp prompts via mapping them to the resource files from the skill. This allows the user to continue to explicitly trigger a subset of functionality.

Use an executable command and a separate mcp argument.

The generated Cursor configuration sets "command": "nve" and "args": ["mcp"]. With "command": "nve mcp", Cursor can treat the full string as the executable name and fail to start the MCP server.

Proposed fix
-      "command": "nve mcp"
+      "command": "nve",
+      "args": ["mcp"]

Replace the invalid TypeScript placeholder.
