Add Skill Card Generator

[pmaiti-nvidia]

Onboarding type

• New product onboarding (new components.d/<slug>.yml file)
• Other (catalog change, README fix, infrastructure, etc.)

For new product onboarding — author affirmations

By submitting this PR, I confirm on behalf of my team:

• Skills cleared for open source release per NVIDIA's internal IP review process (six-question check, all answers affirmative)
• License selected: Apache 2.0 / CC-BY 4.0 / Dual (Apache 2.0 + CC-BY 4.0). Specify: _____
• No new license or new third-party component introduced beyond what the source repo already carries
• Source repo is public and under an NVIDIA-owned GitHub org
• .agents/skills/ or skills/ path used for new entries (or existing path retained for legacy entries per components.d/<slug>.yml)

NVIDIA contributors: see the internal onboarding guide for the IP review process details and license selection.

Reviewer checklist (OSS Skills PIC)

• Author confirmations above are checked
• components.d/<slug>.yml entry valid (required fields, unique catalog_dir, path exists in source repo, filename slug matches name)
• SKILL.md frontmatter spec-compliant (at least one sampled)
• No new license or third-party dependency requiring OSRB filing

All PRs

• All commits signed off with DCO (git commit -s).
  If you forgot, run git rebase --signoff origin/main && git push --force-with-lease to retroactively sign all commits in your branch.

Thanks for opening this @pmaiti-nvidia! Will land this in https://github.com/openclaw/clawhub once shipped.

Approved. Skill Card Generator from NVIDIA/Trustworthy-AI is the cleanest onboarding to date: source-side PR #13 landed all 5 prereqs (renamed skill-card.md, evals.json, signed, SPDX license, bonus BENCHMARK.md from re-running /nvskills-ci after Keshav's announcement). Catalog yml now follows flat-layout convention (lowercase catalog_dir matching skill name) and overrides discussions for the Trustworthy-AI repo that has them disabled. Per-skill LICENSE file present — exactly the right pattern for a CC0 source repo carrying Apache-2.0/CC-BY-4.0 skill content.
