SkillDatabases & data

Lets your agent answer data questions by running SQL across Postgres, BigQuery, Snowflake and other databases.

Available today. Use it from your connected AI after setup.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the Wren CLI skill

About this skill

Wren CLI for AI agents, a semantic SQL layer over 22+ databases (Postgres, MySQL, BigQuery, Snowflake, Spark, …). The actual workflow guides live inside the `wren` CLI itself; this is just a discovery stub. Use whenever the user asks a data question (how many, show me, top N, compare, trend, breakd

What this skill tells your AI

The instructions your AI receives, as published by canner/wrenai in skills/wren/SKILL.md and read by ahel’s review.

This is a discovery stub. The actual workflow guides and prompt helpers live inside the wren CLI itself, so they always match the installed wrenai version (no skill cache, no version drift).

Install: pip install wrenai.

wren docs connection-info <ds>          # required + optional connection fields for a data source

Prompt enhancement (wraps a user question for an agent)

wren ask "<question>" --guided          # for weaker LLMs (strict task flow)
wren ask "<question>" --direct          # for stronger LLMs (minimal wrapping)

Day-to-day data commands (not a sub-app — top-level)

wren --sql '...'                        # execute SQL through the MDL layer
wren query --sql '...'                  # same, explicit
wren dry-plan --sql '...'               # transpile only, no DB hit
wren context show / build / validate    # project / MDL lifecycle
wren profile add / list / switch        # named connection profiles
wren memory index / recall / store      # semantic memory (needs `[memory]` extra)

Run wren --help for the full surface; load the matching wren skills get <name> guide before driving any multi-step workflow.
