"""Strands harness library sketch. Not executed by py_compile.

Versions / setup (docs checked 11 October 2026):
  - Python 3.10+ and: pip install strands-harness
  - or Node.js 20+: npm install @strands-agents/harness
  - CLI on-ramp: npm install -g @strands-agents/cli

Quickstart: Amazon Bedrock is the default, using Claude Opus 5 in the
region your AWS config selects. The model page shows Bedrock ids such as
global.anthropic.claude-opus-5. Pin the id your account has enabled.

create_harness() returns a plain Strands Agent. It is not CreateHarness.
Sessions default under ./.agent — point dir at durable storage before you
leave a laptop. This sketch does not enable shell tools for a refund path.
