01 · The session

What happens when you run it.

Interactive, transparent, scoped. No daemons, no global node_modules, nothing written outside the directories the CLI declared up front.

Signed

Every artifact is verified before it touches your machine. The CLI never trusts the network blindly.

Scoped

The CLI reads detected agent roots up front and writes only there. No surprise paths.

Tracked

Each skill is owned by the CLI. We know exactly what to remove on uninstall.

Reversible

Update keeps a local backup. Rollback in one command.

02 · The library

A growing library of marketing-science skills.

Organized into packs, grouped by job. Starting with MMM and Experiments; new packs ship on the same channel.

pack.1 · Marketing Mix Modeling9 skills

MMM · Meridian

End-to-end Meridian MMM workflow: intake, variable mapping, EDA, feature design, fit, diagnostics, reporting.

pack.2 · Geo & marketing-lift3 skills

Experiments

Design and analyze a geo experiment end-to-end. Power, assignment, pre/post diagnostics, lift estimation.

On the
roadmap

PyMC-Marketing · incrementality · attribution diagnostics · forecasting · more. New packs ship on the same channel; marshy update reconciles.

03 · Agents

Meets you in the agent you already use.

Built on the cross-ecosystem SKILL.md standard. Skills are namespaced so they never collide with anything else in your agent.

04 · Install model

Precise about what it touches.

Ownership tracked per-skill per-root. Updates reconcile only what the pack owns. Uninstall never removes a skill it didn't install.
