Change a Mac's main display resolution in one command: real pixels instead of 4K HiDPI so remote desktop (AnyDesk), screen recording and Screenpipe stop lagging. Use when a remote session is slow or a lower or original resolution is needed: lists modes, picks by width, height, pixel width and refresh rate, self-tests five known traps, verifies after the change and prints a one-line rollback. Triggers: /display-mode, lower the resolution, set 1920x1080, AnyDesk is slow, restore resolution.

Утилита: display_mode.c рядом с этим файлом (CoreGraphics, 0 LLM, без brew). Описание флагов и обе ловушки записаны в шапке исходника.
Портируемость. Родился на Intel Mac Pro (macOS 15, 4K monitor), там проверен. Apple Silicon: тот же API, должен собраться, не проверялся. Windows: веток нет, сделай ChangeDisplaySettingsEx через PowerShell Add-Type. Linux: xrandr --output <имя> --mode 1920x1080.
mkdir -p ~/.claude/scripts/bin && clang -O2 -framework ApplicationServices -o ~/.claude/scripts/bin/display_mode ~/.claude/skills/display-mode/display_mode.c && ~/.claude/scripts/bin/display_mode --selftest
SELFTEST OK обязателен. Swift не бери: на том Mac Pro он не совпадает с SDK и падает.
~/.claude/scripts/bin/display_mode
Колонки W H PW PH HZ, звёздочка = текущий. W H = как выглядит интерфейс. PW = 2×W значит чёткий HiDPI (тяжело для удалёнки). PW = W значит настоящее разрешение, видеокарте и AnyDesk в 4 раза легче.
Всегда все четыре числа, сперва pick (экран не трогает), потом set:
~/.claude/scripts/bin/display_mode pick 1600 900 1600 60
~/.claude/scripts/bin/display_mode set 1600 900 1600 60
set печатает строку отката ДО смены, пишет режим навсегда, перечитывает экран до 2 секунд и печатает OK или MISMATCH. Коды выхода: 0 = ок · 1 = нет режима / ошибка CoreGraphics / не встал · 2 = мусор в аргументах (60Hz, abc) · 3 = неоднозначно (две строки одинаково близки, смотри список). HZ пиши как в списке: 60, 59.875; берётся ближайшая частота, а не первая. Строку отката отдай оператору.
«Уменьши ещё» = следующая ступень вниз в том же формате, что сейчас (16:9 → 16:9). 4:3 (1600×1200, 1280×960) на широком мониторе растягивает картинку, бери только по прямой просьбе.
Лесенка 16:9 на 4K-мониторе: 1920×1080 → 1600×900 → 1344×756 → 1280×720 → 1024×576.
system_profiler SPDisplaysDataType | grep -E 'Resolution|UI Looks'
screencapture -x "$TMPDIR/s.png" && sips -g pixelWidth -g pixelHeight "$TMPDIR/s.png"
Оба обязаны показать выбранный размер.
ioDisplayModeID: у «1920×1080 настоящий» и «960×540 HiDPI» один ID, ставится огромный интерфейс.Все пять сидят в --selftest. Если убрать из выбора высоту, PW или проверку неоднозначности, самотест краснеет.
Только главный экран. Перезагрузку не проверяли: режим ставится как постоянный (kCGConfigurePermanently), а переживёт ли он перезапуск, не доказано.

Run an autonomous consensus round between agent peers on several machines: they negotiate a decision over a shared channel and execute it without a human relaying messages. Use when multiple machines must agree on a change. Triggers: "/03", "work it out among yourselves", "find consensus". Wakes the human only for irreversible actions or a deadlock.

Recover a session after a hard crash (app died, machine rebooted, context lost mid-work): replay the turn-state ledger for the last requests, files and decisions, run a green/red health ping over the system map, file sync and MCP connectors, then rebuild the previous session history for pickup. Triggers: "/1", "resume after crash", "wake".

Show the operator's day: today's calendar plus what needs them personally (leads due, people awaiting a reply, deadlines), pulled from Calendar and Telegram and ranked. Read-only: sends and commits nothing. Triggers: "/agenda", "what's on today", "my agenda".

Rewrite machine-written text so it reads like a busy human wrote it: cut 50-70%, break the even rhythm, drop AI-tell words and filler, keep facts and protected terms. Use before publishing any post, reply or email drafted by a model. Triggers: /ai-slop, /slop, humanize, anti-slop, make it shorter and alive.

Decision protocol for strategic work: recall the knowledge vault, run a gap analysis, emit a deep-research prompt for external tools, then synthesize the returned reports into a decision memo. Use before any new product, feature, market, pricing, GTM or architecture call, where local recall alone is not enough. Triggers: "/alfa-search-recall-deepresearch", "alpha protocol", "R+DR".
