prosi-psi-cli 0.1.2

User-facing PSI command line tools.

Psi CLI

psi is the user-facing command line for setting up and running PSI packages locally.

Install

python -m pip install prosi-psi-cli psihub lllm-core sssn

For OS keyring storage, install the optional secure extra:

python -m pip install "prosi-psi-cli[secure]"

Initialize Local Credentials

Packages can declare launch-time API key requirements in psi.toml:

[requirements.api_keys]
OPENAI_API_KEY = "OpenAI-compatible model access."
ANTHROPIC_API_KEY = "Claude model access."

psi init checks the selected package and guides setup:

psi init packages/analyst-tactics

By default, psi uses the OS keyring when available and falls back to a local .env.local file. You can choose explicitly:

psi init packages/analyst-tactics --credentials keyring
psi init packages/analyst-tactics --credentials env --env-file .env.local

For scripts or CI setup, pass values without echoing them back in command output:

psi init packages/analyst-tactics \
  --credentials env \
  --env-file .env.local \
  --set OPENAI_API_KEY=sk-...

Common provider names follow the usual Python ecosystem conventions: OPENAI_API_KEY, ANTHROPIC_API_KEY, TOGETHER_API_KEY, GEMINI_API_KEY, GROQ_API_KEY, MISTRAL_API_KEY, OPENROUTER_API_KEY, COHERE_API_KEY, HF_TOKEN, TAVILY_API_KEY, and EXA_API_KEY.

Launch A Package

Download a package folder, then launch its primary resource as a FastAPI service:

psi launch packages/analyst-tactics --port 8000

Before importing package code, psi launch checks declared API key requirements. It reads values from the current process environment, the local env file selected with --env-file, and the OS keyring unless --no-keyring is set. Missing keys are reported with a psi init hint.

The launcher reads psi.toml and serves the package's primary resource:

• tactics.* resources become LLLM FastAPI tactic services with /run;
• services.* resources use their FastAPI entrypoint, or fall back to the service's declared tactic when present;
• channels.* resources become SSSN store services with /channels, /events, /subscriptions, /artifacts, and /snapshots.

Inspect what will be served without starting the server:

psi inspect packages/analyst-tactics

psi inspect --json includes API key readiness without printing secret values.

Launch a specific resource when a package has several services:

psi launch packages/society-sentinel --resource services.sentinel_api --port 8130

Direct Python entrypoints work too:

psi launch my_package.service:create_app --port 8000

psi launch is intentionally a local server starter. PsiHub owns package validation, cards, downloads, and metadata; AAAX owns higher-level strategy composition.
