Use this skill when the user asks for a data-backed view that should remain useful after the first render, for example a live dashboard, refreshable report, synced status page, auditable data view, or artifact that can later be refreshed from local/project data or connectors.
Before creating files, decide whether the user actually wants a live artifact or a normal static artifact:
"$OD_NODE_BIN" "$OD_BIN" tools connectors list --format compact. If the named connector is present with status: "connected", choose an appropriate read-only auto tool from its catalog and execute it through the connector wrapper.notion connector plus a user brief that names Notion is enough to start with notion.notion_search using a query derived from the requested artifact/topic. Use notion.notion_fetch_database only when the user supplied a database id or the search result clearly identifies one.template.html as the human-designed HTML template.data.json as the canonical preview data used by {{data.path}} bindings.artifact.json with the live artifact metadata, preview declaration, document declaration, and safe source descriptors.provenance.json with concise source notes, timestamps, non-sensitive connector references, and transformation notes.index.html as source. The daemon derives index.html from template.html and data.json.data.json.references/artifact-schema.md.artifact.json, data.json, provenance.json, or source metadata.raw, rawResponse, payload, body, headers, cookie, authorization, token, secret, credential, and password anywhere in persisted JSON.html_template_v1 interpolation only.

Never persist connector credentials, transport metadata, or raw provider output.status is connected, use the listed tools; if it is not connected, tell the user to connect it in the UI.references/connector-policy.md for listing/execution and credential boundaries, and references/refresh-contract.md for read-only refresh source metadata.index.html is daemon-derived.Every live artifact creation flow must produce these source files before registration:
template.html — declared skill output and source template for the preview.data.json — compact, canonical preview data.artifact.json — create/update input for daemon validation.provenance.json — safe source and transformation summary.index.html is the primary preview entry declared in frontmatter, but it is derived daemon output rather than agent-authored source.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted, and 17 counted toward the lift figure. The other 5 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +45 percentage points is the difference between those two pass rates over the 17 comparable cases. 1 case got worse with the skill loaded, and it is included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
