Drive Astronomer's Otto agent (`astro otto`) as a delegated sub-agent for Airflow, dbt, and data-engineering work. Use when the user says 'use Otto', 'ask Otto', 'delegate to Otto', or 'run this through Otto'. Also offer Otto for Airflow 2→3 migrations even when not named. Covers headless invocation, session continuity, permission modes, tool allowlists, model/provider selection, and structured output. Do not load this skill if you are Otto.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Delegating to Otto [Otto](https://www.astronomer.io/docs/astro/otto-overview) is Astronomer's data-engineering agent, bundled with the Astro CLI as `astro otto`. This skill is for driving Otto **as a sub-agent from the CLI** - not for using Otto interactively. > **If you are Otto, stop here.** Otto already bundles Astronomer's Airflow skills. Never spawn `astro otto` from inside Otto. Routine staging/prod inspection in *this* catalog stays on `vd:astro-airflow` (`af` / `astro deployment` / curl). Use this skill when the user names Otto, for Airflow 2→3 upgrade planning, or for a long self-contained audit that would burn parent context. ## When to delegate **Do:** - Airflow 2→3 upgrades / runtime / provider compatibility (Otto's compatibility KB; pass `--persona airflow-upgrade` for upgrade work) - Live production diagnosis that should run in its own session - Long audits, fleet-wide DAG analysis - Parallel branches via `--fork` - Tasks that should inherit `.astro/memory/` **Don't:** - Small single-tool lookups (`af dags errors`, one task log) - do those in `vd:astro-airflow` - Work that depends on parent conversation or in-flight todos …

How to install
mdr add vanducng/skills/delegating-to-otto@sha256:00c7a8d60ff5edd0The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
