Engine-agnostic oleander lake catalog conventions: catalog.namespace.table naming, hierarchy, and catalog-qualified reads/writes without raw storage paths. Use when naming tables, choosing namespaces, or referencing the lake catalog from Spark, Polars, SQL, or another engine.

## Install

```sh
git clone https://github.com/OleanderHQ/claude-plugin /tmp/claude-plugin && ln -s /tmp/claude-plugin/skills/lake-catalog ~/.claude/skills/lake-catalog
```

## From README

oleander Lake Catalog Use this skill when reading from or writing to the oleander lake catalog from Spark, Polars, SQL, or another engine. Catalog hierarchy Tables are addressed as catalog.namespace.table: catalog: always oleander for the managed Lakekeeper-backed catalog namespace: a logical grouping (e.g., default, sanfrancisco, myorg) table: the table name By default, default and telemetry namespaces are available out of the box. The telemetry namespace contains oleander-managed data you can query directly (for example oleander.telemetry.runevents, oleander.telemetry.traces, and oleander.telemetry.logs). These tables are partitioned on their time column and are reachable over MCP with queryrun — see the lake-query skill. Examples: Referencing tables Always use fully qualified table names through the engine's catalog integration. Do not build raw storage paths such as S3 URIs when reading or writing Iceberg tables.
