NVIDIA Agent Skills

Official, NVIDIA-verified Agent Skills for Claude Code, Codex, and other coding agents.

NVIDIA Agent Skills Spec License

📖 Docs: docs.nvidia.com/skills  ·  📺 Livestream: From Vulnerable to Verified  ·  📝 Blog: NVIDIA Verified Agent Skills: Capability Governance for AI Agents


Skills are portable instruction sets that teach AI agents how to use NVIDIA software optimally: Physical AI and robotics workflows, simulation, CUDA-X libraries, RAG and AI Blueprints, and platform tools. This repository is a catalog: skills are maintained in their respective product repos, and mirrored here daily via an automated sync pipeline. Skills are being added continuously, so check back for updates. We are building this infrastructure in the open, and contributions are welcome. See the Roadmap for what is planned next.


Quickstart

Install NVIDIA skills with the default skills CLI flow:

npx skills add nvidia/skills

The CLI runs through npx and prompts you to choose a skill and install destination. You do not need to clone this repo or copy skill folders by hand.

Requires a current skills CLI (v1.5.16 or newer). Installing via npx skills@latest add nvidia/skills always uses the latest. On older CLIs (v1.5.15 and earlier), skills may install but not appear in Claude Code — see Troubleshooting.

The skill is available the next time your agent loads skills and encounters a relevant task. For example, ask your agent to "solve a linear programming problem with cuOpt" and the skill guides it through the cuOpt Python API. In Claude Code, run /reload-skills to load newly installed skills in your current session.

Install One Skill Without Prompts

Use this when you already know the skill name and want to skip prompts.

npx skills add nvidia/skills --skill cuopt-numerical-optimization-api --yes

Replace cuopt-numerical-optimization-api with any skill name from the Skill Catalog.

Install for a Specific Agent

Use --agent to target a specific AI coding agent. Initially, we'll support common client targets, expanding the list over time. For the full list of clients supported by the spec, see the skills CLI Supported Agents table.

Claude Code

npx skills add nvidia/skills --skill cuopt-numerical-optimization-api --agent claude-code

Codex

npx skills add nvidia/skills --skill cuopt-numerical-optimization-api --agent codex

Snowflake CoCo

npx skills add nvidia/skills --skill cuopt-numerical-optimization-api --agent cortex

Cursor

npx skills add nvidia/skills --skill cuopt-numerical-optimization-api --agent cursor

Kiro

npx skills add nvidia/skills --skill cuopt-numerical-optimization-api --agent kiro-cli

Use --agent more than once to install the same skill into multiple agents.

npx skills add nvidia/skills \
  --skill cuopt-numerical-optimization-api \
  --agent claude-code \
  --agent codex \
  --agent cursor \
  --agent kiro-cli

Keep Skills Up to Date

New skills land continuously, and existing ones are revised, renamed, or consolidated as the catalog evolves. Refresh what you have installed with:

npx skills update

Run it interactively and the CLI also flags skills that were removed or merged upstream (for example, when several skills are consolidated into one) and offers to remove the stale local copies. Use npx skills list to see what is installed and npx skills check to preview what is out of date first.

Browse the Catalog

Use this when you want to see available NVIDIA skills before installing anything.

npx skills add nvidia/skills --list

For non-interactive installs, global installs, agent-specific installs, updates, removals, and fallback manual copying, see Advanced installation.

Verifying Skills

Every published skill ships with a detached OMS signature (skill.oms.sig). The sync pipeline drops any skill missing the required artifacts before publishing, so every skill in the catalog carries:

  • SKILL.md — the skill instructions consumed by the agent
  • skill-card.md — skill identity and governance card
  • skill.oms.sig — detached OMS signature (verifiable against nv-agent-root-cert.pem)
  • A Tier-3 evaluation dataset — accepted at evals/evals.json, evals/*.json, eval/*.json, or benchmark/evals.json
  • BENCHMARK.md — generated benchmark report capturing verifiable uplift data

Verify a skill against the NVIDIA trust anchor nv-agent-root-cert.pem:

pip install model-signing
model_signing verify certificate SKILL_DIR \
  --signature SKILL_DIR/skill.oms.sig \
  --certificate_chain nv-agent-root-cert.pem \
  --ignore_unsigned_files

A successful verification confirms that the skill contents have not been modified since signing by NVIDIA.

See Verify Signed Agent Skills for signature layout, the trust pipeline, and policy options.


Roadmap

  • ✅ Public skills catalog with NVIDIA-verified skills across multiple products
  • ✅ Automated sync pipeline with skills mirrored from product repos daily
  • ✅ Security scanning for all published skills covering instruction safety and supply-chain integrity
  • ✅ Skills signing so every published skill carries a verifiable NVIDIA signature
  • ✅ Skills universal evaluation criteria and task-specific criteria
  • ✅ Skill Card with machine-readable metadata for identity, provenance, quality, and behavioral boundaries
  • ✅ Sync-time compliance gates — signature drift detection and missing-artifact enforcement
  • ✅ Syndication to external marketplaces — Skills.sh, Codex plugin, Claude Code plugin, ClawHub, Hermes Hub
  • 🔲 Syndication to additional MCP hubs and partner channels

Skills are maintained in their respective product repos (see the Source column in the Skill Catalog) and synced to this repo daily. Products only appear under skills/ after the sync pipeline confirms each skill carries:

  • skill.oms.sig — detached OMS-format signature (verifiable against nv-agent-root-cert.pem)
  • skill-card.md — skill identity and governance card
  • A Tier-3 evaluation dataset — accepted at evals/evals.json, evals/*.json, eval/*.json, or benchmark/evals.json

When evaluation runs produce a BENCHMARK.md, it ships alongside the skill so consumers can see verifiable benchmark uplift data.


Standards & Compatibility

This repository adheres to the Agent Skills specification:

  • Skills are portable directories with a SKILL.md file at their root.
  • Metadata uses YAML frontmatter with required name and description fields.
  • Skills follow a progressive disclosure model — lightweight metadata loads at startup, full instructions load on activation.
  • Validate your skill using the skills-ref reference library.

Cosmos-RL

Supervised fine-tuning (SFT) of Cosmos Reason video QA models. The packaged default base model is hf_model://nvidia/Cosmos3-Nano. Pretrained weights are sourced from HuggingFace, not NGC. Gated HuggingFace models require HF_TOKEN. Some Cosmos-RL images cannot load the native Cosmos3 Omni checkpoint format directly; for those images, convert Cosmos3-Nano to a Qwen3-VL HF safetensors directory before train/evaluate and use that converted directory as the PTM path.

Uses FSDP-based parallelism with dp_shard_size for GPU count and dp_replicate_size for node count (not the standard num_gpus/num_nodes).

Requests for "Cosmos Reason 3", "Cosmos3 Nano Reasoner", or nvidia/Cosmos3-Nano are handled by this skill. There is no separate Cosmos3 model directory in the skill bank; route those requests here. Override the base HuggingFace model only when the user explicitly asks for a different model.

Deep detail lives in references; load the smallest one that matches the task:

  • references/cosmos-reason-launch.md — launch intake, preflight, per-action dataset requirements, spec construction, typical overrides.
  • references/cosmos-reason-evaluate.md — evaluate (flat TOML, task types, LoRA eval, selective download, results) and datasets.
  • references/cosmos-reason-automl.md — AutoML/HPO policy and search-space guidance.
  • references/cosmos-reason-parameters.md — important parameters, hardware, error patterns, DEFT/gap analysis, parent-model inference mappings.

Dataclass Schemas

Generated TAO Core schemas are packaged in schemas/<action>.schema.json, with schemas/manifest.json listing available actions. Each generated schema also emits references/spec_template_<action>.yaml from the schema top-level default field. AutoML enablement is declared at the model layer in references/skill_info.yaml via automl_enabled. Runnable AutoML still requires schemas/train.schema.json and references/spec_template_train.yaml to exist and parse. Use the packaged train schema for automl_default_parameters, automl_disabled_parameters, defaults, min/max bounds, enums, option weights, math conditions, dependencies, and popular parameters. Do not expect ~/tao-core at runtime; maintainers regenerate schemas/templates before packaging the skill bank.

Train Action Policy

This model is AutoML-enabled at the model layer. Before handling any train-stage request, read references/skill_info.yaml and resolve the run override from either an explicit automl_policy value or the user's workflow request. Use automl_policy: on by default and only expose on / off in new launch prompts. Treat phrases like "turn off AutoML", "disable AutoML", "no HPO", or "plain training" as automl_policy: off for this run only. When automl_policy: on, automl_enabled: true, and both schemas/train.schema.json and references/spec_template_train.yaml are packaged, route the train action through tao-skill-bank:tao-run-automl by default with this model's skill_dir. Preserve workflow/application overrides for datasets, specs, output directories, GPU/platform settings, parent checkpoints, and automl_policy. Use direct model training only when automl_policy: off or the packaged train schema/template is missing; in the missing-schema case, report that AutoML is enabled but not runnable for this model until schemas are generated.

Non-train actions such as evaluate, inference, and quantize stay in this model skill. The per-run automl_policy override does not change model metadata.

Credentials

  • HF_TOKEN (required for gated models): HuggingFace access token. For the packaged default, the user must accept the model agreement at https://huggingface.co/nvidia/Cosmos3-Nano and provide a token with read access. If the user explicitly overrides the base model, they must accept that target model's agreement too. Passed to the container as a docker_env_var.

Cosmos3 Checkpoint Conversion

When a selected image cannot load the native Cosmos3 checkpoint format (model_type="cosmos3_omni" or Cosmos3ForConditionalGeneration), do not patch QwenVL, Transformers, or vLLM first. Use the upstream Cosmos Framework VLM conversion path to produce a Qwen3-VL HF safetensors directory, then point Cosmos-RL specs at that converted directory.

The model skill packages a helper:

python skills/models/tao-finetune-cosmos-reason/scripts/prepare_cosmos3_vlm_checkpoint.py \
  --checkpoint-path /abs/path/Cosmos3-Nano \
  --output-path /abs/path/Cosmos3-Nano-VLM \
  --secrets-env ~/.tao/secrets.env \
  --validate-with-image <cosmos-rl-image>

After conversion, use the converted directory consistently as the PTM:

train:    policy.model_name_or_path=/abs/path/Cosmos3-Nano-VLM
evaluate: model.model_name=/abs/path/Cosmos3-Nano-VLM
evaluate: model.base_model_path=/abs/path/Cosmos3-Nano-VLM

For local Docker, mount the converted directory read-only into the Cosmos-RL container and set the spec to the container path. If a converted copy already exists and validates, reuse it for PTM baseline evaluation, AutoML recommendations, and final best-checkpoint evaluation rather than converting again.

Training Requirements

  • Dataset type: vlm
  • Formats: llava, daft
  • Accepted dataset intents: training, evaluation, testing
  • Monitoring metric: val/avg_loss, val/reward_avg, val/loss
  • Dataset URI examples: s3://bucket/cosmos/train, s3://bucket/cosmos/eval, /lustre/fsw/tao_datasets/cosmos_rl/train, /lustre/fsw/tao_datasets/cosmos_rl/eval
  • Input modes: accept either dataset roots or direct spec-key paths. Root mode maps <root>/annotations.json plus <root> as the media path. Direct spec mode is valid when annotations and media live in different locations, for example custom.train_dataset.annotation_path=/lustre/.../train.json and custom.train_dataset.media_path=/lustre/.../videos.tar.gz.
  • Media handling: do not ask the user to choose videos.tar.gz vs images.tar.gz unless they are using direct spec mode or the model/action requires a single media archive. In root mode, pass the dataset root as the media path.
  • Annotation validation: before launching train/AutoML/evaluate, verify the annotation JSON is readable and the referenced media path or archive is visible from the selected platform. Do not block, patch, or mutate annotations solely because optional fields are absent.
  • Per-record video FPS: the packaged train template uses custom.vision.nframes, so per-record video_fps is not required by default. If the user switches to custom.vision.fps, selects a dataset profile that requires per-record timing, or uses an image/version that requires video_fps, make it a preflight requirement with --json-required-field train_annotation=video_fps and --json-required-field val_annotation=video_fps before any download or job launch.

Spec construction

cosmos-rl is mode: config. Always start from the packaged references/spec_template_<action>.yaml for the requested action — load it as your base spec via yaml.safe_load(...) and apply user overrides on top. Don't rebuild from scratch.

import yaml
from pathlib import Path

skill = Path.home() / "tao-sdk/tao-skills-external/skills/models/tao-finetune-cosmos-reason"
action = "train"  # train, evaluate, inference, or quantize
specs = yaml.safe_load((skill / f"references/spec_template_{action}.yaml").read_text())
# Now apply your overrides on top of `specs`.

The reference TOML (and the spec the model actually consumes) is nested dicts, not flat dotted keys. Dotted notation in override examples denotes paths into the nested spec — walk the path and assign at the leaf. See skills/platform/tao-run-platform/SKILL.md's "spec is nested dicts" callout. Data source overrides are mandatory for every action.

The packaged template keeps custom.vision.nframes=8 for bounded 1-GPU memory; switch to fps only after checking token budget and GPU memory, and delete custom.vision.nframes from the spec when you do.

See references/cosmos-reason-launch.md for launch intake, the full check_tao_launch_preflight.py slurm/local-Docker examples, the video_fps preflight example, S3 staging, the GPU resource/architecture gate, the per-action dataset requirements table, the /workspace mount caveat, the quantize compatibility shim, and the full typical-overrides list.

Critical Overrides (Train)

These are the keys whose template defaults are wrong or where omission flips the run into a different mode:

ParameterTemplate DefaultRequired ValueWhy
policy.model_name_or_pathhf_model://nvidia/Cosmos3-NanoDirect Docker: nvidia/Cosmos3-Nano, hf_model://nvidia/Cosmos3-Nano, or a local HF snapshot path. SDK/managed platform predownload: hf_model://nvidia/Cosmos3-Nano.Keep the train and evaluate base model aligned.
policy.model_max_length40960Keep at 40960 or higherSmaller than ~40k causes vision_embeds shape mismatch on video inputs
train.train_batch_per_replica32Any multiple of train.train_policy.mini_batchMismatch raises an immediate AssertionError
train.train_policy.type"sft"Keep as "sft" for SFT workflowsIf dropped during agent regeneration, cosmos-rl flips to RL mode → rollout replica allocated → multi-node attempted → hostname errors when num_nodes=1

Evaluate

The evaluator reads a flat TOML config (dataset, model, task, evaluation, vision, generation, metrics, results, num_gpus, results_dir); the actions.evaluate block in references/skill_info.yaml declares inputs and outputs. See references/cosmos-reason-evaluate.md for the flat-TOML config detail, task types ("" General Evaluator vs "its_directionality"), LoRA evaluation via spec_overrides, selective download, results/metrics, and the datasets section.

AutoML / HPO Notes

The packaged default base model is hf_model://nvidia/Cosmos3-Nano; apply it consistently to train (policy.model_name_or_path) and post-training evaluation (model.base_model_path) unless the user provides a different model. See references/cosmos-reason-automl.md for accuracy-vs-val/avg_loss objective selection, the eval_fn per-recommendation evaluate flow, the knob mapping (learning rate, batch size, epochs, weight decay, warmup ratio), example custom_param_ranges, train_sample_count batch-size capping, ordered_int requirements, and the pre-launch recommendation summary.

Parameters, Hardware, Errors, DEFT, Inference

For parallelism, set policy.parallelism.dp_shard_size = GPUs per node and policy.parallelism.dp_replicate_size = node count (1 for single node). Cosmos-RL handles distributed init internally via FSDP and does not rely on platform-level MASTER_ADDR/WORLD_SIZE; submit with gpu_count=<gpus_per_node> and num_nodes=<N> and the spec keys drive sharding. Cosmos-RL models are 8B parameters; recommended 8x A100 or H100 (80GB each).

See references/cosmos-reason-parameters.md for important parameters (training loop, model/policy, parallelism incl. multi-node FSDP, optimization, vision encoders, checkpointing incl. the best symlink/epoch_* resolution, validation, logging), hardware sizing, the full error-pattern catalog (CUDA OOM, LoRA-eval OOM, NaN loss, vision_embeds mismatch, quantize token mismatch, batch-size divisibility and per-rank limits, stale cache, scheduler-None, gated-repo HF_TOKEN, GPU resource/architecture gate, status-logging warnings), DEFT support and scripts/analyze_gaps.py gap analysis, and the parent-model inference mapping table.
