Agent skills for working with Cassis, context maintenance for analytics agents. Keep governed context in Git, test changes with evals, review them through pull requests, and serve the approved version over MCP.
| Skill | What it does |
|---|---|
cassis-ontology-authoring |
Extends an existing Cassis context in a git repository. Hand it a schema dump, dbt YAML, query history or an internal doc, and it writes the context 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 context 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 context authoring skill also ships its playbooks as standalone prompts in its README.
