Structural code intelligence for DeepSeek Harness (dsh) — gives the agent codegraph and codegraph_index tools to find where a symbol is declared, what calls it, and what a change reaches, from a tree-sitter index it builds itself. Compatible with the codegraph CLI's on-disk format.

Service Definition for the DeepSeek Harness code-graph capability seam (ctx.codegraph): a graph-store and graph-indexer provider registry with per-query, order-independent selection over eight normalized structural queries

Read-only SQLite store for the DeepSeek Harness code-graph seam — serves structural queries from the schema-v4 graph at .codegraph/codegraph.db, the same on-disk format the codegraph CLI writes

Database structure for DeepSeek Harness — indexes a database catalog into a local store so the agent knows every table and column before it writes a query, then answers with one tool call
