Dial Your Context

Help a user create the Instructions field content for their Sanity Agent Context MCP. The goal is a concise set of pure deltas — only information the agent can't figure out from the auto-generated schema.

What you're building

The Agent Context MCP already provides the agent with:

• A compressed schema of all document types and fields
• A GROQ query tutorial (~194 lines)
• Response style guidance
• Tool descriptions for GROQ queries, semantic search, etc.

The Instructions field you're crafting gets injected as a ## Custom instructions section between ## Response style and ## Tools in the MCP's instructions blob. It should contain only what the schema doesn't make obvious:

• Counter-intuitive field names (e.g., body is actually a slug, hero is a reference to mediaAsset)
• Second-order reference chains the schema doesn't connect (e.g., "to find products with Dolby Atmos, chain product → productFeature and match on the feature's id field — the schema shows each hop but not the full path")
• Data quality issues the schema can't reveal (e.g., "the product type has a features array but it's always empty — use support-product instead")
• Required filters the agent must always apply (locale, draft status, etc.)
