Scaffold Baseline

A scaffold baseline is the versioned content bundle used by the CLI to render agent skills, hooks, prompt specs, subagent templates, harness mirrors, lint metadata, and catalog metadata.

Sources

• Stable remote baseline: latest GitHub release under baseline/stable/*.
• Bundled fallback baseline: shipped inside the npm executable package.
• Local test baseline: DP_BASELINE_URL=file:///absolute/path/to/scaffold-baseline.
• Optional control-plane metadata source: DP_CONTROL_PLANE_URL.

Invariants

• Baseline releases use baseline/stable/* tags, separate from npm executable tags such as v*.
• Content-only baseline changes can ship without a new CLI binary when they fit the existing catalog schema.
• --baseline bundled and DP_BASELINE=bundled force the offline fallback.
• --refresh-baseline and DP_BASELINE_REFRESH=1 refetch the stable remote baseline.
• Archive downloads are checksum verified before extraction.
• Shared baseline manifest, artifact, provenance, pack, and required-tool shapes belong to Shared Scaffold Model.

Owned Data

• Pack catalog
• Skill catalog
• Tool catalog
• Hook catalog
• Lint asset catalog
• Shared hook and script assets
• Subagent templates
• Selected skill directories

The CLI still owns archive download, extraction, filesystem writes, terminal interaction, repo detection, and update behavior.
