dsh-blackjack

DeepSeek-dealt 21 点 (Blackjack) for the DeepSeek Harness. The DeepSeek model plays dealer — it deals, decides, and trash-talks as one of two selectable personas — while every round is event-sourced into the session log, so hands replay and fork identically. One package ships both the host game service and the browser sidebar UI (a dual-face bundle), installed in a single dsh plugin add.

Install status

• ✅ Complete GitHub install (verified against dsh web): one package = host service + browser UI. The plugin declares both dsh.bundle (the host plugin row) and dsh.client (the web frontend entry); once installed the host layer mounts and the client module system picks the UI up into the frontend boot graph automatically.
• All dependencies are the *published `@deepseek-ai/npm packages** (0.1.0-rc.6`) — no sibling monorepo checkout, no unpublished internal packages.

Features

Host side

• Two dealer personas you pick per session (durable through blackjack/persona events):
  • 🐟 大肥鱼 / Big Fat Fish — a gluttonous, lazy deep-sea fish ("咕噜咕噜").
  • 😼 雌小鬼 / Brat — a smug, cheeky brat who calls you "杂鱼".
• Model-dealt decisions: the dealer decides hit/stand through an auxiliary LLM call, one visible step at a time.
• Cross-round memory: the dealer's prompts carry the running score and the shared chatter history.
• Event sourcing: blackjack/game-start|hit|stand|dealer-hit|settle|banter|emotion|persona are durable session events; the fold replays identically.
• Graceful degrade: with the LLM route absent or failing, the dealer falls back to per-persona preset lines.

Browser UI

• A 🃏 entry in the sidebar footer opens the 21 table in the right details column.
• The table, dealer-mood badge, lifetime record, a chatter feed (dealer banter plus a staggered card-flip draw animation), and an emoji quick-bar.
• Talks to the host through a self-mounted blackjack Remote namespace; the UI holds no game state of its own.

UI preview

The screenshots below come from verified dsh web sessions. The exact cards, dealer lines, and record counters vary with the session log, but they show the complete browser half: the sidebar entry, the table, the chatter feed, and the action bar.

Install (complete: host + UI)

The plugin is a dsh dual-face bundle (dsh.bundle → cordis.patch.yml + dsh.client → lib/client.js):

dsh plugin --profile <name> add github:<owner>/dsh-blackjack

A git install fetches sources, so the first add needs the self-contained prepare build allowed once — copy the pnpm key into the profile's pnpm-workspace.yaml under allowBuilds (see the official publishing guide) and re-run add. Only allow sources you trust.

Verify and boot:

dsh --profile <name> --dump-config   # shows the "# == dsh-blackjack" layer
dsh --profile <name>                 # web surface: dsh web / dsh --profile <name> web

After restarting dsh web, a 🃏 entry in the sidebar footer means the UI is live: the host layer shows in --dump-config, and the client module system automatically scans the dsh.client declaration and weaves the UI into the frontend boot graph (__DSH_BOOT__) — no extra configuration.

Configuration (override in your profile's cordis.patch.yml):

- id: blackjack
  config:
    dealerPersona: 雌小鬼   # initial persona; the durable pick is per-session
    randomBanterChance: 0.3  # unsolicited taunt probability after a hit

Gameplay

Standard Blackjack over one deterministic 52-card deck (seed stored in the game-start event): Aces 11/1, face cards 10, hit/stand, dealer draws to ≥17. Busts lose immediately; equal totals push.
