Obsidian vault as an iPhone<->agent message bus
When typing long messages into the AI from a phone breaks, write them in a notes app that syncs instead.
how it works
SSH TUI paste strips newlines, so the agent writes a session note with a paste placeholder into the iCloud-synced vault; the user fills it on the phone and says 'check it'. Caveat learned: a file landing in iCloud can never notify the phone.
Technique: A pattern or hard-won lesson, written down so it isn't learned twice.
The code for this one lives in a private repo. This page explains the idea so you can build your own.
