Use `ALTER SHARE` only for include-pattern changes.\n- Distinguish physical import (`CREATE DATABASE ... FROM '<file-url>'`) from zero-copy clone sources, and reject filtered shares as clone sources.\n- Use role/grant SQL for governed access and audit it with `SHOW ...` statements; do not preserve `ACCESS ORGANIZATION` as the preferred RBAC pattern.\n- Treat MotherDuck SQL as an additional surface on top of DuckDB SQL, not a replacement for it.\n\n## Workflow\n\n1. Confirm the connection path and whether the question is about syntax, feature support, or a specific error.\n2. Write or repair the statement in DuckDB SQL first.\n3. Verify any MotherDuck-only command or server-mode limitation against the current docs.\n4. If the user needs exact syntax or function details, open `references/SYNTAX_REFERENCE.md`.\n\n## References\n\nRead only the reference sections needed for the current task.\n\n- Read `references/SYNTAX_REFERENCE.md` for DuckDB data types, friendly SQL features, functions, complex types, and common MotherDuck-specific gotchas.\n\n## Related Skills\n\nLoad related skills only for missing capabilities; reuse established context.\n\n- `motherduck-query` for writing and validating analytical SQL against live MotherDuck data\n- `motherduck-connect` when syntax support depends on PG endpoint versus native DuckDB behavior\n- `motherduck-explore` when the problem is really missing schema context rather than missing syntax knowledge\n","tagline":"Look up or repair DuckDB SQL syntax and verify MotherDuck-specific command and feature support.","category":"research","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"motherduckdb","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"motherduckdb/agent-skills","creatorName":"motherduckdb","creatorUrl":"https://github.com/motherduckdb","sourceUrl":"https://github.com/motherduckdb/agent-skills/tree/main/plugins/motherduck-skills-claude/skills/motherduck-duckdb-sql","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/motherduckdb-motherduck-duckdb-sql#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
