arcana-cli 0.1.2

The OS that gives your agents a soul — CLI

arcana-cli

The arcana command-line interface for Arcana OS. A thin Typer wrapper around arcana-core.

uv tool install arcana-cli # or pip install arcana-cli
# or inside the monorepo:
uv sync --all-packages --all-extras

Commands

arcana init

Initialise Arcana OS. Creates ~/.arcana/ with the default directory layout, config.json, and world.json.

arcana init

arcana status

arcana connect

Manage model connections.

arcana connect model                                   # interactive
arcana connect model -p ollama -m hermes-3 -n local
arcana connect model -p anthropic -m claude-sonnet-4-6 -n claude -k sk-...
arcana connect list

Subcommand	Description
model	Add a model connection (interactive or via flags)
list	List configured connections

connect model flag	Description
--provider / -p	ollama, anthropic, openai, openai_compat, or custom
--model-id / -m	Model ID (e.g. hermes-3, claude-sonnet-4-6)
--name / -n	Connection name
--endpoint / -e	Custom base URL
--api-key / -k	API key (stored in the OS keyring, never in plaintext)

---

arcana agent

Manage agents.

arcana agent create                          # interactive card picker
arcana agent create --name scout --card the-fool --model local
arcana agent list
arcana agent show my-agent
arcana agent edit my-agent --card hermit --tags research,deep
arcana agent delete my-agent
arcana agent delete my-agent --yes           # skip confirmation

arcana agent create without flags walks you through a card picker showing all 22 Major Arcana with their archetype and default temperature, lets you toggle optional modifier cards, and prints a blend-compatibility summary before saving. The World is reserved and cannot be assigned.

Subcommand	Description
create	Create a new agent (interactive or via flags)
list	List all agents
show <name>	Show full config for an agent
edit <name>	Update name, description, card, model, or tags
delete <name>	Delete an agent

The --model flag refers to a connection name created with arcana connect model.

arcana run

Run a prompt against a specific agent. --agent is required.

arcana run "Summarise the latest on LLM evals" --agent researcher
arcana run "Refactor this module" --agent my-agent --stream

Flag	Default	Description
--agent / -a	— (required)	Target agent by name or UUID
--stream / -s	off	Stream output token by token

The agent is rebuilt from its stored record and run through a ModelGateway using its configured connection.

---

arcana cards

Browse the card definitions.

arcana cards            # list all 22 Major Arcana
arcana cards show hermit

Subcommand	Description
(default)	List all 22 Major Arcana
show <name>	Show one card's archetype, temperature, and details

---

Runtime layout

All state lives under ~/.arcana/, created by arcana init:

~/.arcana/
├── config.json
├── world.json
├── agents/{id}/        ← agent.json + sessions/
├── connections/        ← models.json
└── cards/{core,custom}/

Secrets (API keys) are stored in the OS keyring, never in these files.

Development

# Type check
uv run pyright packages/arcana-cli/arcana_cli

# Tests
uv run pytest packages/arcana-cli/tests/ -v

Roadmap

This is the Phase 1a MVP command set. Phase 1b adds the commands whose backends land later — arcana memory, arcana world, arcana spread, arcana connect mcp, and an interactive arcana chat REPL.
