description: >
  Agentic tool-use harness driving current open-weight models via
  OpenRouter (own minimal client, not llm-connect — see
  rein-openweights/workplans/REIN-OW-WP-0001-T01), as an alternative to
  frontier-vendor CLIs. Chartered by ADR-001.
handler: glas_harness.reins.rein_openweights:ReinOpenWeights
capabilities:
  session_style: unattended
  model_class: open-weight
  credential_source: rein-local
  # rein-local per ADR-002 (Option B): rein-openweights acquires its own
  # OpenRouter credential (OpenBao, or OPENROUTER_API_KEY env var).
  # glas-harness does not broker it.
status: implemented
Implement the harness contract and prove it against rein-aharness (GLAS-WP-0001-T02/T03/T04) - src/glas_harness/contract.py: Rein ABC (start_session/dispatch_tool/ end_session), SandboxHandle/ToolCall/ToolResult, per docs/harness-contract.md. - reins/rein_aharness.py: adapter around the rein-aharness CLI. Collapses a whole `agent-harness run` into one dispatch_tool call for now (no per-tool hooks yet — tracked in rein-aharness HARNESS-WP-0002-T03); verifies success via new-commit detection, mirroring rein-aharness's own success signal. - gateway.py + cli.py: resolves a sand-boxer sandbox, runs one task through a rein, tears the sandbox down. - registry/reins/*.yaml (rein-aharness implemented, rein-openweights planned) and profiles/harness.agent-dev{,-local}.yaml, pairing with sand-boxer's profile.agent-dev and the new profile.bwrap-local. Tested against a real local git repo + mocked SandboxManager/CLI subprocess (10 tests, all passing). A real live run against the actual Claude Code CLI is deliberately left for a human-triggered follow-up — not executed autonomously since it spends real API credits/credentials.

Add ReinOpenWeights adapter, closing GLAS-WP-0001-T05 glas_harness/reins/rein_openweights.py implements the Rein ABC by shelling out to `rein-openweights run --task-file ... --no-hub [--model ...]`, mirroring reins/rein_aharness.py exactly. Factored the duplicated git_head/write_task_file logic into reins/_shared.py, used by both adapters now. registry/reins/rein-openweights.yaml flipped to status: implemented. 8 new tests (mocked subprocess), 18/18 passing.
