swecc-mesocosm 0.2.5

CLI and Python client for SWECC BenchAnything / Mesocosm (mesocosm + bench commands).

swecc-mesocosm

CLI and Python client for SWECC's BenchAnything / Mesocosm platform.

pip install swecc-mesocosm
mesocosm --help

One package, one command (mesocosm). There is no separate bench binary or swecc-bench on PyPI.

Env author quick start

mkdir my-env && cd my-env
mesocosm init

ollama pull llama3.2
python adapter.py          # terminal 1
mesocosm run local         # terminal 2 — Ollama + benchanything.json, no submit

When ready for the platform: mesocosm auth login → mesocosm env submit (creates the domain from benchanything.json in your repo) → mesocosm run create with the returned domain_id. See LOCAL_DEV.md in your repo after mesocosm init. You do not need mesocosm register domain.py for this flow.

Command overview

Area	Examples
Local env / Ollama	mesocosm init, mesocosm run local
Auth & teams	mesocosm auth login, mesocosm team create
Submit repo	mesocosm env submit --github-url …
Platform runs	mesocosm run create, mesocosm run export RUN_ID
Domain helpers	mesocosm suggest, mesocosm validate, mesocosm register (API JSON/flags; legacy register domain.py only if your repo has DOMAIN_CONFIG)
Bench-api eval	mesocosm doctor, mesocosm eval test, mesocosm run get

See PACKAGING.md in this directory for how bench_common is bundled and how mesocosm run routes local vs platform subcommands.

Install (dev)

pip install -e ./packages/swecc-mesocosm

Configure

mesocosm doctor                    # checks https://api.swecc.org/bench (default)
mesocosm doctor --local            # checks adapter :8765 + local bench-api :8010
export MESOCOSM_LOCAL=1            # same local profile for all commands

Remote defaults: https://api.swecc.org/bench and https://api.swecc.org for auth. Local: see infra/mesocosm.env.example.
