pi-reminders

Pi extension for Apple Reminders on macOS, powered by osascript（AppleScript 命令行）。

This repository is extension-first:

• Always-on /reminders smart slash command
• Empty /reminders = deterministic list of current incomplete reminders in 近期待办
• /reminders <自然语言> = hand back to the current-session LLM, which calls the reminders tool with action
• reminders tool for explicit model-driven calls
• Risk-tiered confirmation: add and complete execute directly, only delete asks once
• Default list: 近期待办

Features

• /reminders → deterministic list, zero LLM cost
• /reminders <自然语言> → let the current LLM understand add / update / complete / delete intent
• reminders(action=list) supports query (title contains), inclusive dueFrom / dueTo (absolute YYYY-MM-DD or YYYY-MM-DD HH:MM), and a positive integer limit; results sort by due date ascending with undated items last
• reminders(action=delete) accepts queries[] for a single batch confirm: resolved targets are deleted after one confirmation, unresolved ones are reported per item
• reminders tool keeps the structured action=add|list|complete|delete|update contract unchanged
• Bounded real RPC smoke: deterministic empty-command list plus nonempty handoff to the current Pi session

Quick start

1. No install needed — osascript is built into macOS. On first use, grant automation permission when prompted (System Settings → Privacy & Security → Automation).
2. Add this repository path to ~/.pi/agent/settings.json under packages.
3. Reload pi.
4. Use:

   /reminders
   /reminders 明天上午九点提醒我给 Curio 发测试邀请
   /reminders 把 ID 为 1234ABCD 的提醒事项标题改成 给 Curio 发正式邀请
   /reminders 把 ID 为 1234ABCD 的提醒事项标记为完成
   /reminders 删除 ID 为 1234ABCD 的提醒事项

Real runtime regression test

Run the extension through the actual pi --mode rpc --no-session protocol:

npx tsc --noEmit
python3 scripts/test-extension-rpc.py
node --experimental-strip-types scripts/test-list-query.ts
node --experimental-strip-types scripts/test-batch-delete.ts
node --experimental-strip-types scripts/test-id-match.ts

The smoke test auto-selects the empty-command list UI and verifies that nonempty /reminders input starts a Pi agent run and delivers its exact text to the current session. test-list-query.ts deterministically covers list-reading semantics (due window, sorting, limit, validation) and tool-result rendering never overflowing the terminal width, without touching the LLM or real reminders. test-id-match.ts is a read-only real-osascript integration test verifying that the short id shown to users resolves to the right reminder for update/complete/delete. Natural-language interpretation and action selection remain the current LLM's responsibility; this extension does not bind a model or automate a model behavior matrix.

Design notes

• The extension talks to Reminders.app directly via osascript.
• No MCP backend is used.
• The public repo is extension-only.
• The goal is a small, always-loaded reminder workflow that stays out of your way.
• The reminders tool contract is for LLM work; the slash command is only the human entrypoint.
