Create and Manage MotherDuck Dives

Use this skill when the user needs a persistent, shareable, editable Dive rather than a one-off chart. Dives are live React + SQL data apps inside MotherDuck; they can be built conversationally, edited from existing workspace content, managed as code, shared with teammates, or embedded in another application.

Source Of Truth

• Prefer current MotherDuck Dive docs first.
• Non-negotiable ordering: when MotherDuck MCP is available, call get_dive_guide before generating Dive code and always before save_dive or update_dive. The guide defines the current component API and runtime libraries.
• Use the blessed Dives example repo as the reference implementation for local preview, Dives-as-code layout, metadata, CI previews, and deploy scripts.
• Use Dives SQL functions when the user wants a scriptable SQL-native create/read/update/delete workflow instead of MCP tools.
• Treat ordinary Dives and embedded Dives separately. Verify current plan entitlements before promising an embed rollout; do not preserve plan names or availability claims from memory.

Default Posture

• First classify the job: new Dive, existing Dive edit, Dives-as-code workflow, team sharing, or embedding.
• Validate the underlying SQL and schema first with motherduck-explore and motherduck-query; a good Dive starts with a correct query.
• Keep Dive queries fully qualified and SQL-heavy; let React handle presentation, not data reshaping.
• Treat the component contract as React + useSQLQuery, a default export, supported runtime libraries, explicit loading/empty/error states, and no browser-side secrets.
• When local preview uses REQUIRED_DATABASES, keep the export on one line and mirror the real share dependencies in metadata or save/update inputs. Avoid aliases that collide with existing database names.
• Start from a named theme direction such as Corporate Dashboard, Tufte Minimal, or FT Salmon instead of vague visual prompts.
• Prefer one query per visual section or interaction surface rather than one giant cross-purpose query.
• Preview locally before saving when the environment supports it.
• For existing Dives, read the current content and version metadata before overwriting anything. MCP list_dives returns current_version, and read_dive can fetch historical versions.
• Treat embedded Dives as the first-choice path when a product needs a live read-only Dive surface with a backend-created embed session. Move to motherduck-build-cfa-app when the app needs custom API contracts, writes, non-Dive routing, tenant policy enforcement, or richer authorization.
• For shared repos or CI/CD, use a service-account token so Dive ownership is not tied to one human user.

Workflow

1. Classify the delivery path: workspace Dive, edit existing Dive, Dives-as-code, share with teammates, or embed in an app.
2. Explore the live schema and validate the core SQL first.
3. Call get_dive_guide if MCP is available, then design the story, sections, interactions, and theme.
4. Build or edit the Dive component, using local preview/hot reload when possible.
5. Call save_dive, update_dive, or deploy only after queries, loading states, required resources, and visual behavior are correct.
6. If teammates or application users need access, configure the underlying shares or embed-session flow explicitly.

For answer, review, or planning requests, stop at the requested design or code artifact. For create, update, or deploy requests, carry the requested in-scope operation through preview and validation; ask before destructive replacement or a broader external rollout that the request did not authorize.
