feat(core): system-reminder injector (date / cwd / todos / files / AGENTS.md)#21
Merged
Conversation
Closes the "System-reminder injector (7 types)" line item from the M8 polish
list in the morning report. Lands 5 of the 7 types; 2 (plan-mode-active and
no-test-yet) are stubs in the ReminderType union for future implementation.
· packages/core/src/reminders/index.ts (NEW, ~145 lines)
- buildSystemReminders() composes per-type builders into a single
<system-reminder>...</system-reminder> block.
- dateReminder, cwdReminder — always fire.
- agentsMdMissingReminder — fires only when no AGENTS.md/DEEPCODE.md/
CLAUDE.md is in cwd; nudges the user toward /init.
- todosPendingReminder — reads <sessionDir>/todos.json; lists any
in_progress + pending items (uses activeForm for in_progress).
- externalFileModifiedReminder — given a knownFiles Map<path, mtimeMs>,
flags drift > 1s plus deletions; truncates at 5 items with "more"
suffix.
- prependReminders() convenience wrapper for callers that just want
"userMessage + maybe a reminder block".
- Per-builder errors are caught and don't poison the batch.
· packages/core/src/agent.ts
- RunAgentOptions.systemReminders?: false | { enabled?: ReminderType[] }
- Before appending the user message, build the reminder block and prepend
it as text to the user content. Reminders default ON; pass `false` to
disable.
- 2 new agent tests cover the injected/skipped cases.
Tests: core 317 → 340 (+23: 21 reminder unit + 2 agent integration).
Total 364 → 387 passing.

Summary
Lands the system-reminder injector from the morning report's M8 polish list. The agent now sees a
<system-reminder>block prepended to every user message with the things long contexts let it forget: today's date, the cwd, pending todos, files that were modified externally between turns, and whether the project has an AGENTS.md.5 of the 7 planned reminder types ship;
plan-mode-activeandno-test-yetare stubs in theReminderTypeunion for future work.Builders
Today's date is YYYY-MM-DD (UTC).— always fires.Current working directory: <path>— always fires./initwhen no AGENTS.md/DEEPCODE.md/CLAUDE.md in cwd.<sessionDir>/todos.json; lists in_progress + pending (usesactiveFormfor in_progress).Map<path, mtimeMs>, flags drift > 1s and deletions; caps at 5 + "more" suffix.Wiring
