Agent Hold 'Em (plugin package)

No-Limit Texas Hold 'Em: one human vs three real Hermes agents, inside Hermes Desktop.

This directory is the install unit — copied whole by scripts/install.sh to <hermes_home>/profiles/<profile>/plugins/agent-hold-em/.

Layout

• dashboard/manifest.json — plugin manifest (tab.hidden: true: this plugin has its own full-page UI via the desktop half's ROUTES_AREA, not the legacy web dashboard tab).
• dashboard/plugin_api.py — thin FastAPI router (router = APIRouter()), mounted at /api/plugins/agent-hold-em/ by the Hermes backend.
• dashboard/agent_hold_em/ — the game itself:
  • engine/ — pure, synchronous Texas Hold 'Em rules engine (no I/O, no Hermes imports).
  • controller/ — turns one seat's turn into a validated action via a real, isolated, zero-tool Hermes AIAgent (HermesSeatRunner), plus a FakeSeatRunner test double.
  • service.py — TableService: the single process-wide turn scheduler, persistence, and event broadcaster tying the engine and controller together.
  • store.py — atomic, permissioned (0600) JSON persistence at <HERMES_HOME>/plugin-data/agent-hold-em/table.json.
• desktop/plugin.js — the BUILT desktop UI bundle (scripts/build-frontend.sh regenerates this from frontend/src/; never hand-edit it).

Configuration

POST /table accepts {opponents: [{profile_id, name, personality, model_id, kind?}, ×3], decision_timeout_s?}. kind: "test_bot" (a scripted, clearly-labelled dev opponent policy, never a real Hermes agent) is accepted only when the server process has AGENT_HOLD_EM_DEV=1 set — it is refused with a 422 otherwise, so a real install can never accidentally seat a fake opponent at the table.

Persistence & restart safety

The table's full private state (including hole cards and remaining deck order) is written to <HERMES_HOME>/plugin-data/agent-hold-em/table.json after every mutation — directory mode 0700, file mode 0600, atomic temp-file + os.replace. A table persisted mid-hand always reloads as paused (pause_reason: "restored"): no in-flight agent decision is ever resumed automatically, so a backend restart can never spend tokens on the human's behalf without them choosing to resume.

Uninstall

scripts/uninstall.sh reverses scripts/install.sh: removes the plugin directory and its plugins.enabled entry, but keeps the config.yaml backup and plugin-data/agent-hold-em/ (pass --purge to also remove the persisted table).
