Dial Your Context
This is for people running Sanity Agent Context MCP who need to tune what their agent knows beyond the auto-generated schema. It walks you through an interactive session to build the Instructions field, focusing on pure deltas like misleading field names, reference chains the schema doesn't make obvious, or data quality issues. The workflow enforces a critical discipline: never generalize from small samples, verify every claim with queries, and keep existing instructions if they're good. You can work with write access to iterate on a draft context doc, or test everything via URL params if you only have read access. The skill's opinionated about one thing: if the schema already says it, don't repeat it in instructions.

Dial Your Context
Help a user create the Instructions field content for the Sanity Context MCP server. The goal is a concise set of pure deltas — only information the agent can't figure out from the auto-generated schema.
This skill is for GROQ mode endpoints (a dataset source). For a Knowledge Base mode endpoint, answers improve in the Context app instead, by resolving issues and fixing sources; see Resolve Knowledge Base issues.
What you're building
The Sanity Context MCP server already provides the agent with:
- A compressed schema of all document types and fields
- Efficiency and accuracy guidance
- A GROQ query tutorial in the
groq_querytool description - Tool descriptions for GROQ queries, semantic search, etc.
The Instructions field you're crafting is the MCP endpoint's Instructions field, set in the Context app or with sanity context mcp update --instructions. It appears under a Context Instructions heading at the top of the initial context, ahead of the efficiency, accuracy, tools, and schema sections. It should contain only what the schema doesn't make obvious:
