Bad Decisions

Bad Decisions is a reusable engine and service for fill-in-the-blank party card games. It provides a validated pack registry, a stateless REST API, a browser client, a terminal client, and CardDeck portable-pack archives.

The engine makes no network requests while serving a hand and never changes packs through the HTTP API. Prompt and response selectors are independent; the registry is loaded at startup and can be run with multiple workers.

Install

python -m pip install bad-decisions
bad-decisions --help
bad-decisions --oneshot

The cross-platform client is separate:

python -m pip install bad-decisions-client
regret health
regret deal

The configured hosted browser client is at /bad-decisions/web/.

Packs

Set BAD_DECISIONS_PACK_DIR to an absolute registry directory. It replaces the bundled registry and is loaded only at startup.

bad-decisions pack validate example.carddeck
bad-decisions pack init-registry /absolute/pack/registry
bad-decisions pack import example.carddeck /absolute/pack/registry

CardDeck 1 defines the portable format. Its ZIP validation rejects traversal, symlinks, unexpected members, checksum mismatches, oversized content, and dangerous compression ratios before any pack is written.

Bundled content retains its own provenance and licensing. The coffee pack is owner-authorized material based on IRC messages, distributed under CC BY-SA 4.0; its raw source-message corpus is not included. The base pack is licensed CC BY-NC-SA 2.0; operators distributing it must honor those terms.

API

uvicorn bad_decisions.api:create_app --factory --host 127.0.0.1 --port 8000
curl http://127.0.0.1:8000/healthz
curl http://127.0.0.1:8000/v1/packs
curl 'http://127.0.0.1:8000/v1/round?packs=base'

/docs exposes OpenAPI documentation. Errors use a stable JSON envelope and request responses include a request ID.

Linux deployment

Bad Decisions is Linux-native for production deployment:

bad-decisions setup
sudo NGINX_SITE_CONFIG=/etc/nginx/sites-available/example.com \
  PUBLIC_BASE_URL=https://example.com/bad-decisions \
  ./deploy.sh

The deployer creates an unprivileged service account, immutable wheel releases, a bad-decisions.service unit, and optional loopback nginx proxy configuration. See DEPLOYMENT.md.
