Reminder

Set timed reminders and manage todos.

IMPORTANT: how a reminder actually fires

A row in reminders.db is just a note — nothing scans it or delivers it. To make a reminder that actually fires and gets delivered, you MUST create a scheduled job with the cronjob tool, which persists to the scheduler and is delivered through the active channel by Echo Agent's scheduler service:

cronjob(action="create", name="weekly-report",
        schedule="0 9 * * 1", command="提醒你写周报")

The reminder_store.py script below is only a lightweight local note-taking list (list/done/delete). It has NO delivery path on its own. If the user wants to be reminded at a time, use cronjob — optionally also recording a note via the script. For a background one-off that must take effect, spawn_task can run the cronjob call for you.

Jobs that produce a file (audio/image/document)

When the scheduled command generates an artifact the user must receive (e.g. a voice briefing), make the delivery happen inside the same tool call — do not assume a later step will send it. For audio use text_to_speech(..., deliver=true) (see the tts-voice skill); for other files call send_file explicitly with the target channel/chat. An unattended cron run may end right after producing the file, so "generate then hope it gets sent" silently drops the artifact.

After creating a job: confirm, then stop

Once cronjob(action="create") returns, you are done. Send the user ONE confirmation with the concrete facts and end the turn:

• job id, the schedule, and the next fire time (from the create result)
• if a delivery target was inferred, say so; if the create result carried the "⚠️ 无法确定投递目标" warning, relay it and ask for target_channel/target_chat_id.

Do NOT try to "prove delivery works" by exercising the agent's own plumbing — reading gateway/server.py, a2a/server.py, or curling internal endpoints like /v1/chat or /api/v1/message is not verification, it's a rabbit hole that burns the turn and leaves the user with no reply. If you genuinely need to sanity -check the schedule, use cronjob(action="list"); trigger a real run at most once and only if the user asked. The scheduled job itself is the delivery test — it will fire on schedule.

Quick Commands

Action	Example
Set reminder	"提醒我明天9点开会"
Recurring	"每周一早上8点提醒我写周报"
List	"显示我的所有提醒"
Complete	"完成提醒 #3"
Delete	"删除提醒 #5"

Time Parsing

Natural language to cron expression mapping. Feed the resulting expression into the cronjob tool's schedule argument:

Input	Cron Expression
明天9点	0 9 {tomorrow} * *
每天早上8点	0 8 * * *
每周一	0 9 * * 1
每月1号	0 9 1 * *
2小时后	one-shot timer
工作日下午5点	0 17 * * 1-5

Local note storage (no delivery)

The script keeps a local note list in SQLite: ~/.echo-agent/reminders.db. This is bookkeeping only — creating a row here does NOT schedule or deliver anything. Timed delivery is the cronjob tool's job (see top of this doc).

CREATE TABLE reminders (
    id INTEGER PRIMARY KEY,
    content TEXT NOT NULL,
    cron_expr TEXT,
    next_fire DATETIME,
    is_recurring BOOLEAN DEFAULT 0,
    is_done BOOLEAN DEFAULT 0,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

Script Usage (local notes only — does not schedule delivery)

python3 scripts/reminder_store.py add "写周报" --cron "0 9 * * 1"
python3 scripts/reminder_store.py list
python3 scripts/reminder_store.py done 3
python3 scripts/reminder_store.py delete 5
python3 scripts/reminder_store.py due  # show due reminders

Delivery

Delivery is handled by the scheduler, not by this script. When you create a job with the cronjob tool, the scheduler fires it on schedule and routes the message through the active channel (Telegram/WeChat/etc). The reminder_store.py script never delivers anything by itself.
