• Teach Hermes an incident-triage playbook and reuse it in a fresh session - Python

Running the examples as a test suite

Every example is exercised nightly against live E2B by tests/run-examples.ts: each one is uploaded into a fresh sandbox, installed with its own toolchain (npm, uv, Poetry, or nbconvert for notebooks) and run. An example passes if it exits 0.

npm install
npm test                      # all of them
npm test -- hello-world       # substring filter, one or a few

You need an E2B_API_KEY plus whichever provider key the examples you are running use - see .env.example. hello-world-js and hello-world-python need only the E2B key, so they are the ones to try first.

What counts as a failure. The suite checks the sandbox, not the model. A provider rate limit or an exhausted quota counts as OK, because the sandbox still built, installed and ran; non-deterministic model behaviour - no chart produced, a malformed tool call, generated code raising inside the sandbox - is reported as skipped. Real failures are the things that are actually broken: missing templates, dependency resolution, wrong entrypoints, auth, retired model ids, sandbox timeouts.

Some examples are deliberately not covered - they need a provider key this repo does not hold, a long-lived server the runner cannot assert on, or an upstream fix. Each exclusion is listed with its reason at the top of tests/run-examples.ts, so a gap is never silent.
