WhoDB

What it does

WhoDB adds database exploration and query capabilities to the agent. It provides MCP tool bindings (preferred) and CLI fallbacks to run schema discovery, list connections, describe tables and columns, execute SQL queries, and export results. Use it to quickly inspect unfamiliar schemas, sample data, run ad-hoc analysis, and export query results to CSV/XLSX for reporting.

When to use it

Activate this skill when the user asks for database introspection, writing or running SQL queries, exporting table/query results, discovering schemas or tables across Postgres, MySQL, MariaDB, SQLite, MongoDB (via adapters), Redis, Elasticsearch or ClickHouse. It covers both interactive MCP tool usage and CLI alternatives when MCP is unavailable.

What's included

• Scripts: none in the SKILL.md (has_scripts=false)
• References: none bundled with the skill (has_references=false)
• Instructions: concrete command examples for MCP tool calls (whodb_connections, whodb_query, whodb_schemas, whodb_tables, whodb_columns) and CLI fallbacks (whodb-cli query/schemas/tables/columns, connections management, export). The document also provides workflows for exploration, sampling data, and best practices (use LIMIT, prefer specific columns, avoid exposing credentials).

Compatible agents

Inferred compatible agents: Copilot/Codex-style assistants and MCP-enabled agents that can call MCP tools or invoke shell commands. The skill assumes the agent can use tool calls for structured results or shell commands as fallback.
