Create and Manage MotherDuck Dives

Source Of Truth

• Prefer current MotherDuck Dive docs first.
• Non-negotiable ordering: when MotherDuck MCP is available, call get_dive_guide before writing Dive code and before every save_dive or update_dive. The guide defines the current component API and runtime libraries.
• get_dive_guide also surfaces relevant conventions from the reserved dives Guide topic. Apply those conventions when they do not conflict with the user's explicit requirements.
• 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.
• New Dives start as Draft. Promote a validated Dive to Ready only when the requested delivery includes publication. Only an admin can mark a Dive Endorsed; never self-endorse an agent-created Dive.
• When reusing existing work, prefer Endorsed and then Ready Dives. Archived Dives are retired and excluded from default agent listings unless explicitly requested.
• 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.
• Preserve an existing Dive’s visual system for scoped edits. For a new Dive, choose a concrete theme direction that fits its audience.
• 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. Use edit_dive_content (exact text replacements) for focused edits and update_dive for a full rewrite.
• Add export controls only when the use case calls for them: exportAs on a query result or the useExport hook (CSV, JSON, Parquet, XLSX), started from a click. Do not build Blob URLs, hidden anchors, or COPY TO exports.
• Dive SQL is read-only. For actions such as approving a record, submitting a form, or refreshing a pipeline, have a button start a Flight the Dive owner controls with useRunFlight and track it with useFlightRun (from @motherduck/react-sql-query). Hardcode the Flight ID, pass only string config values, disable the control while a run is pending, render the hook's error, and rerun the affected queries when the run succeeds. Viewers need a run grant: recommend the grantees and grant only after the user confirms. Embedded Dives cannot run Flights.
• Viewers can open AI Chat in the Dive header. It sees the Dive's queries, data, and current filters, and can edit the Dive with each change kept in version history. Clear section titles, query names, and the Dive description make its answers better.
• 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. Choose the requested delivery path: workspace Dive, existing edit, Dives-as-code, write-back actions, sharing, or embedding. Follow only that path; a chart request does not itself authorize sharing, embedding, or write-back.
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. Read the resulting URL, version, and status back. If the requested delivery includes publication, promote a validated Draft to Ready through the write-capable path.
7. If teammates or application users need access, check three things: they can view the Dive, every REQUIRED_DATABASES entry is a share they can read, and they hold a run grant on each Flight the Dive runs. Prefer an existing share of an owned database (MD_INFORMATION_SCHEMA.OWNED_SHARES). When the user asks to share the Dive's data with the whole organization, share_dive_data creates org-scoped shares and updates the Dive in one call; use motherduck-share-data for restricted audiences, and the embed-session flow for application users.

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.
