datahub-search is a skill for Claude Code from datahub-project/datahub-skills. It costs 125 tokens per session (5,423 once invoked), scanned A, original, Apache-2.0.

A search and question-answering tool for DataHub, a catalog that stores information about an organisation's datasets, tables, columns, owners, and related metadata.

In plain words
What is it for?
Use it to find datasets, browse by platform or domain, identify owners, check columns, and investigate metadata such as personally identifiable information (PII).
Why use it?
It helps you find data and understand its context without manually browsing the catalog or asking several teams for basic information.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

datahub-search scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 423 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

This skill operates in two modes:

  • Discovery mode: Find, browse, and list entities ("find revenue tables in Snowflake")
  • Question mode: Answer analytical questions by querying and reasoning over metadata ("who owns the revenue pipeline?")

Multi-Agent Compatibility

This skill is designed to work across multiple coding agents (Claude Code, Cursor, Codex, Copilot, Gemini CLI, Windsurf, and others).

What works everywhere:

  • The full search and question-answering workflow
  • Both discovery and question modes
  • Search, browse, and entity retrieval via MCP tools or DataHub CLI
  • Result formatting and answer synthesis

Claude Code-specific features (other agents can safely ignore these):

  • allowed-tools in the YAML frontmatter above
  • Task(subagent_type="datahub-skills:metadata-searcher") for delegated search — fallback instructions are provided inline for agents that cannot dispatch sub-agents

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/.


Not This Skill

If the user wants to... Use this instead
Explore lineage, upstream/downstream, impact analysis /datahub-lineage
Create assertions, run quality checks, raise/resolve incidents /datahub-quality
Update metadata (descriptions, tags, ownership) /datahub-enrich
Install CLI, authenticate, configure defaults /datahub-setup

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
