Create Lunar cataloger plugins (Bash scripts) that build the software catalog — syncing components and domains from external systems, or classifying them from custom signals like repo files, CI config, or each component's Component JSON.

Create Lunar collector plugins that gather SDLC metadata for guardrail enforcement. Use when building collectors (Bash scripts) that collect data from repositories, CI pipelines, or external APIs and write to the Component JSON. Covers hook types (code, cron, ci-after-command), the `lunar collect` command, plugin structure, containerization, and best practices.

Edit `lunar-config.yml` — wire together components, domains, collectors, policies, catalogers, and initiatives for a Lunar deployment.

Create Lunar policy plugins that enforce engineering standards. Use when building policies (Python scripts) that evaluate Component JSON data and produce pass/fail checks. Covers the lunar_policy SDK (Check class, assertions, Node navigation), enforcement levels, handling missing data, plugin structure, and testing patterns.

Craft correct SQL queries against the Lunar data model. Use when querying Lunar's PostgreSQL SQL API to analyze components, checks, policies, domains, or PRs. Covers view schemas, join patterns, filtering by component/commit/PR, time series queries, and JSONB path expressions.

Write Earthfiles for repeatable, containerized builds. Use when creating build automation with Earthly - a tool combining Dockerfile and Makefile concepts. Covers targets, artifacts, caching, functions, imports, Docker-in-Docker, CI integration, and best practices.
