OpenTag

OpenTag is a local-first coordination layer that turns workplace mentions into governed coding-agent runs. It connects collaboration platforms such as Slack, GitHub, GitLab, Linear, Telegram, Discord, Microsoft Teams, and Lark or Feishu to local executors. Each request becomes a bounded context packet whose permissions and executor capabilities are checked before work begins. Codex, Claude Code, or another compatible agent performs the task and returns concise results to the original thread. Action receipts show proposed changes and expose an Apply option only when an approved adapter can safely perform them. A local work ledger records the source event, admission decision, context, capabilities, artifacts, callbacks, and final outcome. The CLI supports guided setup, diagnostics, terminal operation, and background services on macOS and Linux.
