Masthead Agent Skills

A curated collection of Agent Skills for working with Masthead Data — BigQuery data observability and cost optimization for Google Cloud.

Prerequisites

Before installing, make sure you have:

• A Masthead Data account with a provisioned insights dataset. Request access →
• gcloud CLI authenticated (gcloud auth login)
• bq CLI available (bq version to verify)
• BigQuery permissions: ability to run jobs and read data in your project

When a skill runs for the first time it will ask you for your Masthead insights dataset ID (e.g. my-project.masthead_insights). It stores this in your project's instructions file so you won't be prompted again.

Installation & Usage

These skills are designed to be consumed directly by AI agents such as Claude Code or GitHub Copilot.

Claude Code

Add the Masthead plugin to your Claude Code tools configuration (about Claude Code plugins):

/plugin marketplace add masthead-data/for-agents
/plugin install masthead-data-skills@masthead-data
/reload-plugins

GitHub Copilot / Vercel Skills CLI

Use the Vercel Skills CLI to install skills directly into your project:

# Install all skills globally (available in all projects)
npx skills add masthead-data/for-agents --global

# Install a specific skill
npx skills add masthead-data/for-agents --skill masthead-storage-savings-with-tables

Once installed, ask your agent naturally:

Optimize my BigQuery storage costs using Masthead insights

Available Skills

masthead-compute-savings-with-data-models

Optimize BigQuery compute costs by assigning Dataform, dbt, or Airflow models to slot reservations or on-demand compute.

What you get: updated reservation assignment config for your orchestration tool (Dataform, dbt or Airflow), verified against live Masthead recommendations.

masthead-storage-savings-with-tables

Optimize BigQuery storage costs by identifying and removing dead-end and unused tables.

What you get: a reviewed CSV of waste candidates ranked by savings impact, and a ready-to-run shell script to drop approved tables.

masthead-storage-savings-with-datasets

Optimize BigQuery storage costs at the dataset level by switching storage billing models and setting expiration policies.

What you get: a prioritized list of datasets eligible for billing model changes or expiration policies, and ready-to-run commands to apply them.
