+# Plan: Fix NO_REPLY check to use trim/startsWith
+
+GitHub issue: #80
+
+## Problem
+
+When a cron LLM response starts with `NO_REPLY` but includes additional text (e.g. `NO_REPLY\n\nExplanation...`), the exact match `output === "NO_REPLY"` fails and the entire response gets delivered to the user.
+
+Real example from bedtime-reminder cron:
+```
+NO_REPLY
+
+Завтра (1 апреля) нет событий с конкретным временем...
+```
+
+## Root cause
+
+`bot/src/cron-runner.ts:394`:
+```ts
+if (cron.type === "llm" && output === "NO_REPLY") {
+```
+
+Exact match doesn't handle trailing whitespace or extra text after `NO_REPLY`.
+
+## Fix
+
+Change line 394 from:
+```ts
+if (cron.type === "llm" && output === "NO_REPLY") {
+```
+to:
+```ts
+if (cron.type === "llm" && /^NO_REPLY(\s|$)/.test(output.trim())) {
+```
+
+Regex requires word boundary (`\s` or end-of-string) after `NO_REPLY` to avoid false matches on strings like `NO_REPLY_EXTRA`.
+
+Also check `bot/src/stream-relay.ts` and `bot/src/message-queue.ts` for similar NO_REPLY checks — apply the same pattern everywhere.
+
+## Files to change
+
+- [x] `bot/src/cron-runner.ts` — line 394, fix the check
+- [x] Search all `NO_REPLY` checks in `bot/src/` — apply same fix if exact match found
+- [x] Add/update tests for NO_REPLY with trailing text, whitespace, and clean NO_REPLY
+
+## Tests
+
+- [x] `NO_REPLY` exact — should be swallowed
+- [x] `NO_REPLY\n\nSome text` — should be swallowed
+- [x] `  NO_REPLY  ` — should be swallowed
+- [x] `NO_REPLY_EXTRA` — should NOT be swallowed (regex word boundary correctly rejects this)
+- [x] Regular output — should be delivered
