On Harnesses
One worked example runs through this batch: planning a family's meals for the week. Larder builds the harness from an empty folder. Ontology writes down the small world that harness works in, so the answer stops changing between sessions. Both are in Claude Code, and neither requires the other.
- Larder
Build a small assistant for dinner out of one agent and a folder of plain files, and learn the shape that transfers to most of the other things you keep doing by hand: when the answer is wrong, correct the file, not the answer.
- Ontology
Operationalize an ontology with a language model. Give the agent a small model of the kitchen instead of a list of what is in it, so the answers stop wobbling from one session or model to the next, and check that model with a script, because it is only worth having once something checks it.
