# rein-openweights An agentic tool-use harness that drives **current open-weight models via OpenRouter** (through `llm-connect`), as an alternative to the frontier-model-vendor harnesses (Claude Code, Grok CLI, Codex/GPT CLI). Part of the glas-harness "rein" family — see [glas-harness ADR-001](../glas-harness/docs/adr/ADR-001-rein-harness-family.md) and this repo's [workplans/REIN-OW-WP-0001](workplans/REIN-OW-WP-0001-bootstrap.md). Not yet pushed to Forgejo — local scaffold only.
