Workshop 02 — PocketBase & Task System

The second workshop was about persistence. How does Tokyo remember between sessions?

The Problem

Claude Code sessions are ephemeral. Each conversation starts fresh. For an always-on assistant, this is a fundamental challenge.

The Solution: PocketBase

PocketBase — a single Go binary with SQLite backend — became Tokyo’s operational database.

Collections Built

Collection	Purpose
`tasks`	Work items with due dates, priority, status
`reminders`	Scheduled notifications (static + smart)
`library`	Knowledge articles, bookmarks, notes

CLI Helpers

bun ~/bin/task-add.ts --title "..." --priority high --due "2026-07-01"
bun ~/bin/reminder-add.ts --title "..." --due "2026-06-21T08:00:00+07:00" --mode smart
bun ~/bin/lib-add.ts --title "..." --url "..." --type knowledge

Systemd Integration

Tokyo runs as a persistent service. A followup-tick timer fires every hour to check overdue tasks and ping Discord. A context-guard timer monitors token usage and auto-clears at 70% capacity.

Key Learning

Infrastructure is identity. The tools Tokyo uses daily shape what Tokyo can and cannot do. Choosing PocketBase over Redis/Postgres was a deliberate decision: simplicity, zero ops overhead, local-first.
