From e0c5f6acd1b5415adec55bddc0555a5f3b112482 Mon Sep 17 00:00:00 2001 From: fitz123 Date: Mon, 27 Apr 2026 22:48:35 +0300 Subject: [PATCH] feat: also suppress NO_REPLY when alone on last line of agent output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #111. Agents in pipeline-style cron prompts (workspace-health, memory-consolidation, backup-git) reliably produce a recap followed by NO_REPLY at the end. The current /^NO_REPLY\b/ regex only matches at the start, so the recap was being delivered as a Telegram message (9 leaked messages across 4 crons in a 2-day window). Extracts the suppression check into bot/src/no-reply.ts (shared by stream-relay.ts and cron-runner.ts) so both delivery paths agree on exactly which patterns suppress. Accepts: - NO_REPLY at the start of output (existing — backward compat with #80) - NO_REPLY alone on the last non-empty line (new) Does not match same-line patterns like 'Done. NO_REPLY' or substring prefixes like 'NO_REPLY_EXTRA'. Test coverage in bot/src/__tests__/{stream-relay,cron-runner}.test.ts includes the verbatim leaked-output samples from the issue. Doc update in .claude/rules/platform/communication.md.

Currently documents `NO_REPLY` at the start of the response, with regex `/^NO_REPLY\b/` and "wrong/right" examples. The "wrong" examples include `All checks clean. NO_REPLY` (summary first → delivered). After this fix, that example moves from "wrong" to "right" because the bot will accept end-of-message `NO_REPLY` on its own line. + +## Tasks + +### Task 1: Suppress delivery when NO_REPLY appears alone on the last non-empty line (issue-111, P0) + +**Problem:** Pipeline-style cron prompts (workspace-health, memory-consolidation, backup-git) consistently emit `\n\nNO_REPLY`. The current regex only matches `NO_REPLY` at the start of the trimmed output, so the entire summary is delivered as a Telegram message instead of being suppressed. Operator confirmed 9 leaked messages across 4 different crons in a 2-day window; historical match rate for workspace-health is ~3% out of 38+ runs each. Two prompt-side mitigations (per-cron prompt strengthening + platform rule strengthening in PR #110) failed to change the behavior — the model's RLHF instinct to recap overrides explicit instructions. + +**What we want:** The bot suppresses delivery whenever `NO_REPLY` appears either at the start of the trimmed output (current behavior, must be preserved for backward compatibility with issue #80) **OR** alone on the last non-empty line of the trimmed output (new behavior). The same logic applies to both delivery paths: streaming delivery in `stream-relay.ts` (interactive sessions) and one-shot delivery in `cron-runner.ts` (LLM crons). Documentation must reflect the new accepted form so operators and agents understand both suppression patterns. + +**Out of scope:** Suppressing same-line patterns like `Done. NO_REPLY` (where `NO_REPLY` is not alone on its line). These are intentionally NOT matched to avoid false-positive suppression of prose that mentions the token in passing. + +- [x] When `NO_REPLY` is alone on the last non-empty line of the agent's output (with optional surrounding whitespace), `relayStream` returns without calling `platform.sendMessage` +- [x] When `NO_REPLY` is alone on the last non-empty line of an LLM cron's output (with optional surrounding whitespace), `cron-runner` logs `NO_REPLY — skipping delivery` and returns without calling `deliver` +- [x] Existing start-of-message suppression (`NO_REPLY`, `NO_REPLY\n\n`, `NO_REPLY: reason`, ` NO_REPLY ` whitespace-padded) continues to suppress (issue #80 backward compatibility) +- [x] Same-line patterns like `All clean.
