Add 'Напомнить завтра' snooze button to add-coupon reminders

[github-actions]

Problem

Add-coupon reminder DMs contain only text asking the user to add coupons and instructions to open /my to mark coupons as Использован/Вернуть. There is no inline "Напомнить завтра" (snooze) button, so users must manually reopen the bot UI, which increases friction and leads to forgotten coupons.

Evidence

• Usage metrics (product-data-report):
  • Total Interactions (7d): 276 (previous period: 389) — overall engagement is down.
  • Command 'added' (7d): 5; Command 'add' (7d): 3 — low add counts.
  • Callback actions (7d): addflow: 22 — users do engage with flows, suggesting a small UI affordance could help.

Code Checked

• src/CouponHubBot/Services/ReminderService.fs — the add-coupon reminder message is "Не забудь добавить купоны в бота" and is sent as plain text (no inline keyboard).
• src/CouponHubBot/docs/TELEGRAM-BOT-LOGIC.md — documents reminder behaviour and ADD_COUPON_REMINDER_LOOKBACK_DAYS, but no mention of a snooze button.
• src/CouponHubBot/Services/CommandHandler.fs and src/CouponHubBot/Services/BotHelpers.fs — existing per-coupon buttons are "Вернуть" and "Использован", no "Напомнить"/snooze callback handlers.

Expected Behavior

When the bot sends a personal add-coupon reminder DM, include an inline keyboard with a simple Напомнить завтра button that snoozes the add-coupon reminder for 1 additional day (the message should stay human-readable if buttons are not rendered). The implementation should be reversible and respect ADD_COUPON_REMINDER_LOOKBACK_DAYS (i.e., snoozing delays the next reminder for 1 day while still obeying the lookback window).

Product agent re-check (2026-09-25):

What I reviewed

• Chat evidence: user request at 2026-09-19 11:02 asking for a "напомнить завтра" button (see orchestration bundle).
• Code: src/CouponHubBot/Services/ReminderService.fs and related bot helpers.

Findings

• The add-coupon reminder DM is sent as plain text: "Не забудь добавить купоны в бота" (see ReminderService.fs).
• No inline keyboard or callback for a "напомнить завтра" / snooze action is present in the reminder path. A code search for "напомнить завтра", snooz, or a remind_tomorrow callback returned nothing.

Outcome

• The feature-request ("Add 'Напомнить завтра' snooze button") remains valid: the behavior is not implemented on main.
• Suggested next step: keep the issue open as low/medium priority and consider a small patch that adds an inline keyboard to the add-coupon reminder DM with one Напомнить завтра callback that re-schedules that user's DM for +1 day. This is a small UX change but respects the product vision note about button creep; consider A/B or opt-in per-admin.

Re-check: feature-request #514 — "Add 'Напомнить завтра' snooze button to add-coupon reminders"

What I checked

• Product-data-report (chat):
  • 2026-09-19 11:02 -1002001071234 3563d299 не только на совести, но и на памяти! а можно (если это не сложно) сделать под напоминалкой кнопку "напомнить завтра" ? ...
  • 2026-09-27 11:52 -1002001071234 be6126fd Сегодня вот тоже разбили, проблем нет, но надо напоминать, проактивно могут не предложить
• Code (current main):
  • src/CouponHubBot/Services/ReminderService.fs:115-119 — the overdue-taken DM is built as plain text and sent via SendMessage.Make(userId, text) with no reply_markup / inline keyboard.
  • src/CouponHubBot/Services/ReminderService.fs:126-131 — the "add-coupon" reminder likewise sends plain text "Не забудь добавить купоны в бота" with no buttons.

Conclusion

• The implementation currently sends plain-text DMs (no inline buttons). The requested small UX improvement (a "Напомнить завтра" / snooze button in the DM) is still not implemented.
• The change aligns with src/CouponHubBot/docs/PRODUCT-VISION.md (expiration reminders are in-scope) and is a low-friction UI tweak consistent with the bot's simplicity requirement.

Recommendation

• Keep Add 'Напомнить завтра' snooze button to add-coupon reminders #514 open as feature-request / priority-medium (current labels) and implement as a small UI change:
  • Add an inline keyboard button Напомнить завтра on the reminder DM that issues a callback like reminder:snooze:1 (1 day), which the bot handles by recording a per-user snooze and suppressing that user's add/overdue reminder until the snooze expires.
  • Implementation notes for the team: Add callback handler (idempotent), small DB flag or snooze_until column, and update ReminderService to respect snoozes.

No new issue created — duplicate of #514.
