openshain: an AI employee with an audit trail

Editorial interest 86/100 Selection signal · not a rating of the site

An open-source Japanese agent harness that turns AI-assisted company work into recorded, resumable Work items.

Landing page captured for the 2026-09-07 issue.

Field notes

At v0.3.1, openshain models company work as resumable Work records rather than disposable chat turns. Its documented receipt example processes 296 rows and keeps calculation in a CSV tool instead of asking the model to perform arithmetic. The underlying record is an append-only work/<id>/events.jsonl file containing requests, tool calls, model responses, usage, and artifact hashes. The page also shows MCP configuration for using the same harness from Claude Code or Codex.
