Track expenses in chat without exposing amounts in groups

With the ledger plugin loaded, send 记 午饭 18.5 to record an expense. 本周消费 shows the week's total with a per-category breakdown, and 删账 <id> deletes one of your own entries. No model or Agent is required. Commands use Chinese aliases; each also has an English name such as ledger-add.

Prepare

Follow the ledger plugin README to install it with a persistent Database Host. Set timezone to your local IANA timezone: today, this week (starting Monday) and this month are all computed in it. The daily report also needs the Schedule Feature.

Record and query

记 午饭 18.5 和同事
记 打车 23
今日消费
本周消费
本月消费
分类统计 本月
账单
删账 2

Amounts are stored as integer cents with at most two decimals; negative or malformed amounts are rejected. Each person's entries are stored separately and ids only refer to your own entries.

Use it in a group

Recording works in groups, but replies hide the amount. Query results are sent to you privately and the group only sees a notice. When the platform cannot send a private message, the group sees categories and counts with amounts shown as ¥***.

Daily report

Send 记账日报 开启. At the configured reportTime (22:00 by default) the bot privately sends the day's summary, once per day. 记账日报 关闭 cancels it.

Done when

• 本月消费 in a private chat shows the right total and category shares.
• Amounts never appear in group messages.
• After opting in, one private daily report arrives at reportTime.
