Engineering notes on building and using a machine-consumable error knowledge base.

Error lookup for your coding agent

2026-09-05

309,555 library error records, each pinned to the source line that raised it, available to agents over MCP with no API key and no network after the first sync.

Run ErrLookup on your own internal repositories

The pipeline is a local CLI and the dataset is static files — analyze private code on your own hardware and serve the results from any internal host.

Why error lookup matters most for compiled languages

When a Go binary or a JAR throws in production, the error string is often the only artifact you have — the source that raised it never shipped.

How the ErrLookup scanner works
