§01

modes

Press shifttabto cycle build → plan → ask without leaving the prompt.

build

edits need yes

Clarifies with ask_user when the tree can’t settle a choice. Shell and every file edit need a yes.

ask

no writes

Search and explain only. No edits, no shell. Switch to Build to apply changes.

plan

approve → build

Explores the tree, then emits a plan. Approve picks a build model and starts implementing.

§02

why zeta

Nothing silent

Shell and file writes ask first. Bash can be allowed for the session; every edit still needs a yes.

Your models

All models via BYOK or OAuth - bring your own keys and providers. Configure in /config; switch with /model.

Local by default

Chat history stays under ~/.zeta. Resume anytime, auto-compact when the window fills.

/review

Bundled playbook for a strict code-quality pass on the current branch - structure first, nits later.
