AI coding agents are limited to how autonomously they can work because they have no model of the codebase as a whole. Polygraph is a meta-harness that gives agents what they're missing: Visibility across every repo boundary and memory that survives the session. Connect all your repos, private and public, into a unified dependency graph without moving any code. Resume, reference or build on any session created by any developer, on another machine, even on different agents.

Could you build this?
Partial Building cross-repository static analysis, symbol resolution, and scalable semantic code graphs across many large repositories requires complex AST indexing beyond standard LLM vibe coding.
What it would actually take: The system requires an indexing engine parsing multi-language ASTs (e.g., via Tree-sitter or SCIP/LSIF), cross-repo dependency resolution, and a hybrid vector/graph database (like Neo4j or Memgraph + Qdrant) to maintain persistent relational code entity graphs. Building the meta-harness also requires robust sandboxed MCP server orchestration and real-time cache invalidation on git webhooks.
