From af39300572bf4494370a1d0be19ce3c1ff330d36 Mon Sep 17 00:00:00 2001 From: Chinesezjc Date: Thu, 24 Sep 2026 16:54:55 +0800 Subject: [PATCH 1/8] feat(schedule): frame due reminders as scheduled user messages Due reminders entered their Session as user-role messages whose fixed text told the model to treat the reminder prompt as untrusted content rather than new user instructions. Both delivery paths now open with one shared origin line, "This is a scheduled message from the user", so the message states where it came from instead of what standing to give its own payload. One-shot and recurring batch framing share SCHEDULED_MESSAGE_FRAMING, so the two paths cannot drift. The bracketed markers and the JSON-encoded dynamic fields are unchanged, so a prompt still cannot forge framing lines. The rationale and alternatives are recorded in the Agent Note .agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.md. --- ...-09-24-scheduled-message-framing.i18n.yaml | 19 +++++++++++++ .../2026-09-24-scheduled-message-framing.md | 27 +++++++++++++++++++ ...2026-09-24-scheduled-message-framing.zh.md | 27 +++++++++++++++++++ apps/web/tests/schedule-after.e2e.ts | 4 +-- packages/schedule/schedule/README.md | 4 +-- packages/schedule/schedule/README.zh.md | 4 +-- packages/schedule/schedule/src/domain.ts | 11 +++++--- packages/schedule/schedule/tests/cron.spec.ts | 2 +- .../schedule/schedule/tests/daily.spec.ts | 2 +- .../schedule/schedule/tests/domain.spec.ts | 4 +-- .../schedule/schedule/tests/weekly.spec.ts | 2 +- 11 files changed, 91 insertions(+), 15 deletions(-) create mode 100644 .agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.i18n.yaml create mode 100644 .agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.md create mode 100644 .agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.zh.md diff --git a/.agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.i18n.yaml b/.agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.i18n.yaml new file mode 100644 index 0000000000..74a86707d4 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.i18n.yaml @@ -0,0 +1,19 @@ +# Bilingual-pair consistency record for 2026-09-24-scheduled-message-framing.md (docs/i18n/README.md): per heading +# section, a hash of its English and Chinese blocks outside code blocks and generated regions. +# After editing either side, bring the other along and re-record with: +# pnpm run verify-translation-pairing --write .agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.md +/agent-note-delivered-reminders-are-framed-as-scheduled-messages-from-the-user: + en: f524c3b0ee74c586 + zh: ec4e85f0fd853532 +/agent-note-delivered-reminders-are-framed-as-scheduled-messages-from-the-user/problem: + en: 78527813a5263803 + zh: 955248a48613ece8 +/agent-note-delivered-reminders-are-framed-as-scheduled-messages-from-the-user/decision: + en: 495f9159b9ae06a7 + zh: 6d2882f085c3bf4e +/agent-note-delivered-reminders-are-framed-as-scheduled-messages-from-the-user/alternatives-considered: + en: 35aa7f7e135d29d3 + zh: b5601f65839d47bb +/agent-note-delivered-reminders-are-framed-as-scheduled-messages-from-the-user/consequences: + en: 80ef6bfad499664d + zh: 1b6944ec78d8202c diff --git a/.agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.md b/.agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.md new file mode 100644 index 0000000000..0d07dfaaaf --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-09-24-scheduled-message-framing.md @@ -0,0 +1,27 @@ +# Agent Note: Delivered reminders are framed as scheduled messages from the user + +Status: implemented + +English | [中文](2026-09-24-scheduled-message-framing.zh.md) + +## Problem + +Due reminders reach their original Session as user-role messages with producer kind `schedule`.
