From e38ef956e6d6fa66a8ee74182127848c4508f5c4 Mon Sep 17 00:00:00 2001 From: coding-buddy dev Date: Sun, 26 Jul 2026 12:33:30 +0200 Subject: [PATCH 1/3] fix(server+hooks+README): make buddy_react the primary end-of-turn channel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The HTML-comment channel broke visibly in Claude Code v2.1.169+ (issue end-of-turn, steering the model to the broken channel while keeping the working MCP tool unused. Result: every assistant message leaked the raw line and the primary model-authored path never fired. Accept-with-changes verdict on PR #127: that PR keeps the HTML comment as primary and adds a canned-pool fallback for when the comment is missing. That trades a visible-artifact bug for the same canned-pool loss the user already complained about ('suspicious English placeholder shit'). The real fix is the in-process option: make buddy_react the primary channel (it renders nowhere in the transcript and is model-authored by construction), keep the HTML-comment extractor as a backward-compat fallback for older Claude Code versions, and only fall through to a canned-pool line as a last resort. Changes: * server/state.ts — ReactionSource = tool|comment|fallback|none; ReactionState.source is optional and loaded as 'none' for legacy files. saveReaction() takes an optional source argument (default 'tool' since every MCP-side caller is one). * server/index.ts — getInstructions() and buddy://prompt now direct the model to call buddy_react at the end of every turn, with explicit examples. The contradictory 'Do NOT use buddy_react for end-of-turn comments' line is gone, as is the 'do NOT append an invisible HTML comment' steer. buddy_react / buddy_pet / buddy_unmute tag their writes source=tool or source=fallback. buddy_stats now loads the reaction file and shows the last line + its source so users can prove the bubble is not canned. * hooks/buddy-comment.sh — header rewritten to describe the 3-source chain; bookkeeping (turn counter, XP, memory) always runs on assistant message; reaction write skipped when a fresh source= tool reaction is on disk; otherwise tries the legacy HTML comment (source=comment) then falls back to a pool pick via the new server/turn-reaction.ts script (source= fallback). Cooldown still rate-limits the reaction write, not the bookkeeping. * server/turn-reaction.ts — new canned-pool entry used only as the last-resort fallback. Mirrors what PR #127 added but with the source tag wired through. * README.md — features card and 'How It Works' updated to describe the new chain and provenance tag; the '' Stop Hook line is replaced with the actual chain (skip tool → comment → fallback). Tests: bun test (246 pass, 0 fail). bun run typecheck clean. Smoke tests confirmed all three reaction paths (comment writes source= comment, canned fallback writes source=fallback, fresh tool reaction is left alone).

Speech Bubbles
-Your buddy comments on your code in real time. Invisible, contextual, alive. +End-of-turn reactions come from the model by default (MCP tool call). When that doesn't fire — older Claude Code, no MCP, a turn where the model didn't react — a Stop hook falls back to a tagged canned pool line so the bubble is never silent.

Reviewer (Opus 5) flagged the regression; this restores the fixes with TDD discipline: tests written FIRST, verified to fail against the prior code, then the fix. F1 — per-turn sentinel (CRITICAL). The 60 s wall-clock freshness gate lost tool reactions on any turn longer than 60 s, which is ordinary for agentic coding (90 s-5 min). Stop hook now writes its run time to '.last_stop_hook.' after each invocation; a tool reaction is treated as 'from this turn' iff its timestamp is more recent than the previous Stop hook run. F2 — clock skew guard. Tool timestamps implausibly in the future (beyond 60 s) are treated as clock-skew garbage and the hook falls through to the comment / pool branch. 'lastStopRun' on the writer side is clamped to min(lastStop, now) so a future-dated marker does not poison the comparison. ('react.ts' now distinguishes a future tool timestamp from a legitimate one instead of rejecting both as 'age < 0'.) F3 — saveReaction contract. Default source flipped from 'tool' to 'fallback'. writeStatusState no longer calls saveReaction implicitly — every hatch / pet / unmute call path now writes its own provenance explicitly, so /buddy stats can no longer lie about canonical 'tool' lines being canned. F4 — pool-write hooks tag their provenance. react.ts, mood-react.ts, file-type-react.ts, name-react.ts all now write 'source: fallback' alongside reaction / timestamp / reason. Legacy files without the field default to 'none' on load. F5 — bookkeeping respects the rate limit. 10 short turns inside the default 30 s cooldown window now produce 1 turn-counter increment and 2 detached bun boots, matching main's behavior. Bookkeeping still fires on the fresh-tool-skip path (so the stop marker is stamped) but does NOT increment turns or spawn XP / memory on the path where the tool already wrote the reaction. F7 — literal '{lines}' dropped. The line '*nervous laughter' {lines} lines changed.' in the large-diff pool would render literally as the hook only substitutes {files} and {branch}. Removed. A new test scans every DEFAULT_REACTION_POOLS entry for any unsubstituted {name} token and asserts none (catches future regressions of this class). F9 — atomic write pattern. saveReaction now uses tmp + rename on the reaction file (torn reads were a sub-bug in the freshness gate's read). The Stop hook does the same on reaction / cooldown / stop-marker writes. New test asserts no leftover 'reaction.*.tmp.*' files remain after a hook run. Tests added (all written before the fix and verified to fail): server/hooks/buddy-comment.test.ts: F1 long-turn: 5-min tool reaction is preserved F1 fresh-tool: skipped even within default cooldown; bookkeeping does NOT spawn (F5) F2 future-clock: 5-min-future tool timestamp is clobbered F5 cooldown: 10 rapid-fire turns → events.turns === 1 server/hooks/{react,mood-react,file-type-react,name-react}.test.ts: F4 each hook's reaction file has source: 'fallback' server/state.test.ts: F3 saveReaction without source defaults to 'fallback' F3 writeStatusState does NOT clobber an existing source='tool' reaction in reaction.$sid.json Tests / typecheck: bun test: 369 pass / 0 fail bun run typecheck: clean Branch state: rebased onto origin/fix/react-channel (e38ef95). F6 statusline-only framing from a5d2bd1 is preserved verbatim — the maintainer's directive (reactions are statusline-only, not echoed in the transcript) is intact across the changes in this commit.
