Semantix connects your agent harness to the resource layer with slice extraction, BM25 retrieval, and stable context injection.Current public evidence comes from repository tests and synthetic demos. Cost and performance gains in production remain unverified.

Features

Reuse context.Keep evolving.

Shipped capabilities, traceable evidence, and explicit limits.

Semantix provides slice extraction, BM25 and hybrid retrieval, and stable injection. Scheduling, prefetching, and parameter feedback remain interfaces or experimental features. Production cost savings must be measured separately with real sessions.

LOOP A / MEMORYCapture → Reuse
LOOP B / SCHEDULINGDecide → Prefetch
LOOP C / EVOLUTIONFeedback → Adapt

Components

One kernel. Four components.

Four component groups turn each session into reusable experience: ingest and slice, retrieve and reuse, orchestrate resources, then enforce boundaries through validation and feedback.

Community

Every contribution should be verifiable.

Semantix is developed openly on GitHub. Every issue, pull request, and validation result should include inputs, methods, and conclusions others can inspect.
