W&B Artifacts and Registries

Use this sub-skill when a task involves versioned datasets, models, files, directories, external object-store references, artifact aliases/tags/types, downloads, artifact CLI commands, or linking artifacts into registries/model registries.

Route by task

• Create or log artifacts: Use references/workflows.md#create-and-log-versioned-artifacts and references/api-reference.md#artifact-construction for wandb.Artifact, add_file, add_dir, add_reference, and Run.log_artifact patterns.
• Consume or download artifacts: Use references/workflows.md#consume-and-download-artifacts and references/api-reference.md#artifact-consumption for Run.use_artifact, wandb.Api().artifact, Artifact.download, Artifact.file, and path forms.
• Use artifact CLI: Use references/cli-reference.md for wandb artifact put, get, ls, and cache cleanup syntax and path expectations.
• Link to registries: Use references/workflows.md#link-artifacts-to-registries and references/api-reference.md#registries-and-linking for Run.link_artifact, Artifact.link, registry paths, aliases, and public API registry helpers.
• Debug failures: Use references/troubleshooting.md for invalid names/types, missing files, credentials, optional storage dependencies, alias/version confusion, finalized mutation errors, and registry path/link errors.
• Offline validation helper: Run python sub-skills/artifacts-and-registries/scripts/artifact_manifest_smoke.py --help from the root skill directory to validate names/types and preview a local manifest without upload.

Boundaries

This sub-skill covers artifact creation, artifact references, artifact lifecycle operations, artifact CLI usage, registry linking, registry lookup, and storage integration gotchas. For general scalar/media metric logging, use the experiment-tracking sub-skill. For large Public API reporting and automation beyond artifacts/registries, use public-api-and-automation. For launch jobs or sweeps that consume artifacts, use sweeps-and-launch after preparing artifacts here.
