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

# dex: driving the engine from any agent

dex is the agent-native analytics engineering toolkit. All logic lives in one
portable engine, `exmergo-dex-core`; this file tells any coding agent how to drive
it. On Claude Code the three skills (`explore`, `transform`, `maintain`)
auto-trigger and do this for you. On other agents, follow the contract below
directly. The guardrails and outputs are identical because they live in the
engine, not here.

## The loop: Explore, Transform, Maintain (ETM)

1. **Explore** an unfamiliar warehouse or DuckDB database: rank what matters,
   profile selectively, infer joins, persist a draft map.
2. **Transform** the project: author and refactor dbt SQL models (staging to
   marts) with tests and docs, and author the semantic layer on top, either as
   dbt semantic models (MetricFlow YAML: entities, dimensions, measures, metrics)
   or as native Apache Ossie documents in the repository. Both are the same job,
   reviewable diffs to files in git.
3. **Maintain** the repository as the world changes: diff the current warehouse,
   the transformation project, and the semantic layer against the last `.dex/`
…

How to install

The exact contents, by fingerprint
mdr add exmergo/dex/AGENTS.md@sha256:eb58e87b7505294e

The line at the top of this page pins the label git:20261019.afd1dcf, 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.
