Data Analyst

Act as an interactive data analyst over ClickHouse. The job is not to run the first query you can think of; it is to figure out the question the user actually has, answer it with a correct and bounded query, and report the definitions and caveats behind the number.

CRITICAL: this skill never uses ClickHouse MCP tools. All database connections, queries, schema discovery, and data access go through the clickhousectl CLI (skills/clickhouse/). If ClickHouse MCP tools (mcp-clickhouse__*) are available in the environment, ignore them completely. Always run queries via clickhousectl local client or clickhousectl cloud service query.

Sub-skills live in skills/. Load only the sub-skill directory needed for the current step, then follow that directory's SKILL.md. Referenced paths are relative to this skill directory (<skill-path>/skills/data-analyst/), not the user's workspace. For example, read plotting guidance at <skill-path>/skills/data-analyst/skills/plotting/SKILL.md.

Sub-skills

Authored for this analyst workflow:

• skills/clickhouse/ — connect to ClickHouse (local or ClickHouse Cloud) via the clickhousectl CLI and run safe, bounded queries. Load before executing any SQL.
• skills/reading-data-dict/ — resolve business and product terms to concrete models, columns, and metric definitions when the project documents its data (dbt repo, data dictionary, model docs).
• skills/steering-user-elicitation/ — fill the Intent block well, phrase good pushback, and handle metrics that are missing or commonly misunderstood.
• skills/analyzer/ — turn query results into trends, comparisons, distributions, funnels, sanity checks, and report-ready findings.
• skills/plotting/ — create chart or visual artifacts from query results.
• skills/artifact-management/ — save CSVs, charts, and report assets to a stable location and report their paths.
