astrogilda/waitbus

Skill Claude CodeCodex

The workstation-local, cross-harness status bus, a blocking wait/emit primitive that lets any agent or script wait on, or emit, CI / pytest / Docker / filesystem events (finish or fail) without polling, framework-agnostically. GitHub Actions is source.

Open-Agent-Tools/Postcard

Skill Claude CodeCodex

Use when the user wants to message, notify, or coordinate with another AI agent session running on this machine — or asks who else is active. Wraps the oat-postcard CLI (send, reply, inbox, directory, log, whoami) and the postcard-reader subagent for mail triage.
