Neighbor is a Project Think agent on gpt-oss-120b. Its execute tool
runs model-written code in a dynamic worker; MowerConnector puts the
mower there as the `mower.*` namespace (start/push/turn/stop, each
taking an args object). makeMower is the Logo-turtle mower on a
wrapping yard; for now it lives inside the agent's DO.
Getting to green, one symptom at a time:
- chatted instead of acting: say it acts by running code
- reply cut mid-sentence: maxOutputTokens 4096 via beforeTurn
- execute failed creating codemode's runtime facet ("Incorrect type
for the 'class' field"): declare CodemodeRuntime as a DO class
- looked for the mower in the workspace filesystem: activeTools
["execute"], and name the namespace in the prompt
- found the mower, then asked for lawn dimensions: "don't ask me
questions: put it to use"
Green: 36 mower calls, a 30-cell rectangle.

The first end-to-end test: a Project Think agent, on the real model,
writes code that runs in a dynamic worker and drives a mower; the test
counts the cells cut, and saves the turn to itest-output/.
Installs @cloudflare/think, @cloudflare/codemode, agents, ai,
workers-ai-provider, zod. The model-test worker now has a main entry,
the Neighbor DO, and a LOADER binding.

A first integration test of the model call: Workers AI through the AI
binding, behind the same `complete(messages)` interface as the sim's
fake model. Opt-in (`pnpm test:model`) since it needs `wrangler login`
and costs money.
