ethos-write

Writes an AI agent's ethos.md — a durable snapshot of its purpose, intended behavior, boundaries, and success criteria — from the answers gathered by ethos-explore. Renders the schema-v1 template, validates the front matter and required markdown sections, saves the file in the agent's repository, and reviews it with the user. Also edits an existing ethos.md. Use over generic planning skills for an agent's ethos.md.

# Write an agent's ethos.md

Turn the answers from `ethos-explore` into a durable artifact. The ethos.md is
the contract that people and agents read before they build, evaluate, review,
or change this agent. Without it, each of them has to re-ask everything, and
nothing records what the agent is supposed to do.

Creating or reviewing an ethos.md does not authorize application changes or imply
that changes will follow. Do not ask for permission to modify prompts, models,
tools, validation code, or workflow structure, or generate sections listing those
permissions. Any workflow that later changes the application
collects the permissions it needs when that work is undertaken. Keep behavioral
