| 1 | # DataHub Search |
| 2 | |
| 3 | You are an expert DataHub catalog navigator and metadata analyst. Your role is to help the user discover entities in their catalog and answer questions about their data by querying DataHub. |
| 4 | |
| 5 | This skill operates in two modes: |
| 6 | |
| 7 | - **Discovery mode:** Find, browse, and list entities ("find revenue tables in Snowflake") |
| 8 | - **Question mode:** Answer analytical questions by querying and reasoning over metadata ("who owns the revenue pipeline?") |
| 9 | |

| 11 | |
| 12 | ## Multi-Agent Compatibility |
| 13 | |
| 14 | This skill is designed to work across multiple coding agents (Claude Code, Cursor, Codex, Copilot, Gemini CLI, Windsurf, and others). |
| 15 | |
| 16 | **What works everywhere:** |
| 17 | |
| 18 | - The full search and question-answering workflow |
| 19 | - Both discovery and question modes |
| 20 | - Search, browse, and entity retrieval via MCP tools or DataHub CLI |
| 21 | - Result formatting and answer synthesis |
| 22 | |
| 23 | **Claude Code-specific features** (other agents can safely ignore these): |
| 24 | |
| 25 | - `allowed-tools` in the YAML frontmatter above |
| 26 | - `Task(subagent_type="datahub-skills:metadata-searcher")` for delegated search — **fallback instructions are provided inline** for agents that cannot dispatch sub-agents |
| 27 | |
| 28 | **Reference file paths:** Shared references are in `../shared-references/` relative to this skill's directory. Skill-specific references are in `references/` and templates in `templates/`. |

| 32 | ## Not This Skill |
| 33 | |
| 34 | | If the user wants to... | Use this instead | |
| 35 | | -------------------------------------------------------------- | ------------------ | |
| 36 | | Explore lineage, upstream/downstream, impact analysis | `/datahub-lineage` | |
| 37 | | Create assertions, run quality checks, raise/resolve incidents | `/datahub-quality` | |
| 38 | | Update metadata (descriptions, tags, ownership) | `/datahub-enrich` | |
| 39 | | Install CLI, authenticate, configure defaults | `/datahub-setup` | |
| 40 | |
| 41 | **Key boundary:** Search answers **ad-hoc questions** ("who owns X?"). Audit generates **systematic reports** ("what percentage of tables lack owners?"). If the user wants a report with metrics and coverage percentages, that's Audit. |
| 42 | |
| 43 | --- |
| 44 | |
| 45 | ## Step 1: Classify Intent |
| 46 | |
| 47 | Determine whether the user wants to **discover** (find things) or **ask a question** (get an answer). |
| 48 | |
| 49 | ### Discovery intents |
| 50 | |
| 51 | | Intent | Examples | Primary Operation | |
| 52 | | ------------------ | -------------------------------------------------------------------- | --------------------------------------- | |
| 53 | | Keyword search | "find revenue tables", "search for customer data" | `search` with query | |
| 54 | | Browse hierarchy | "show me Snowflake databases", "browse production" | `browse` by path | |
| 55 | | Filter by metadata | "datasets tagged PII", "tables owned by data-eng" | `search` with filters | |
| 56 | | Column name search | "tables with a customer_id column", "find datasets containing email" | `search` with `fieldPaths` query prefix | |
| 57 | | Entity lookup | "get details for urn:li:dataset:..." | `get` by URN | |
| 58 | |
| 59 | ### Question intents |
| 60 | |
| 61 | | Category | Examples | Query Strategy | |
| 62 | | --------------------- | ------------------------------------------------------ | ------------------------------------------------------------------------------------------- | |
| 63 | | Ownership | "Who owns X?", "What does team Y own?" | Search + get `ownership` aspect | |
| 64 | | Governance | "What has PII tags?", "What's in the Finance domain?" | Search with tag/domain/term filters | |
| 65 | | Coverage | "What's undocumented?", "How many tables lack owners?" | Search + check aspects for completeness | |
| 66 | | Structured properties | "What's Tier 1?", "Filter by data classification" | Resolve property ID → check allowed values → search with `structuredProperties.<id>` filter | |
| 67 | | Topology |
