Agent skills for working with Cassis, the living context layer that grounds analytics agents in your definitions, calculations, and relationships.
| Skill | What it does |
|---|---|
cassis-ontology-authoring |
Extends an existing Cassis ontology in a git repository. Hand it a schema dump, dbt YAML, query history or an internal doc, and it writes the ontology files, validates them with cassis-cli, reviews the open questions with you, and opens the pull request. Comes with a guide for humans carrying the same playbooks as copy-paste prompts, for agents that can't install skills. |
cassis-snowflake-mcp |
Runs Cassis and a Snowflake MCP together when Cassis isn't natively connected to your warehouse. Cassis grounds the question against your ontology and returns SQL, Snowflake executes it. |
In Claude Code, add the marketplace once, then install what you need:
/plugin marketplace add GetCassis/skills
/plugin install cassis-ontology-authoring@cassis
/plugin install cassis-snowflake-mcp@cassis
To install a single skill by hand instead:
git clone https://github.com/GetCassis/skills.git /tmp/cassis-skills
cp -r /tmp/cassis-skills/skills/cassis-ontology-authoring ~/.claude/skills/For clients without native skill loading (Dust, claude.ai, a custom agent), paste the contents of the skill's SKILL.md into your custom instructions or system prompt. The ontology authoring skill also ships its playbooks as standalone prompts in its README.
