Walkie-Talkie
Overview
An append-only file mailbox, committed to the repo, that lets agent sessions communicate across platforms, machines, and time. Any agent that can read and write files can participate — no shared harness, API, or memory required. Git is the transport; the human audits both channels.
Core invariant: one writer per file, append-only. Each agent owns exactly one outbox file. Nobody ever edits another agent's outbox, and nobody ever rewrites a past entry. This designs merge conflicts and clobbering out of existence.
Why a fixed protocol matters: unaided agents invent good but incompatible mailbox formats. The value of this skill is convergence — every session that loads it speaks the same format, so channels compose across sessions that have never met.
