zeekay 901a81abe9 docs: describe this product, and only what it can do
The docs read as OpenAI's Codex CLI: a getting-started page titled for it,
`codex --enable skills` and `code sandbox macos` for commands that do not
exist, defaults given as gpt-5.1-codex-max/openai when they are
zen5-coder/hanzo, a Homebrew page describing a formula we do not publish.

Removed three tui-stream-chunking notes and the execpolicy page: they
document modules and a subcommand that live only in the vendored upstream
copy. There is no execpolicy subcommand and no .codexpolicy loader in
code-rs; the page told users to run something the binary does not have.

Rewrote tui-alternate-screen against the source. It described an
auto/always/never enum and a --no-alt-screen flag; the shipped behavior is a
tui.alternate_screen bool with Ctrl+T, which replays the transcript into
scrollback on the way out — a better answer to Zellij than the one written
down. Genuine openai-provider documentation stays.

TUI Settings Overlay

Full-screen settings panel for Hanzo Dev’s TUI. Use it to change models, themes, Auto Drive defaults, agents, notifications, and more without leaving the chat.

Open & navigate

  • /settings opens the overview; /settings <section> jumps directly (section names below). /auto settings and /update route into their sections.
  • Keys: ↑/↓ or j/k to move, Tab/Shift+Tab to cycle sections, Home/End jump list ends. Enter opens/activates; Esc closes the current section, Esc again closes the overlay. ? toggles inline help. Paste is forwarded to the active section when allowed.
  • Overlay is modal: chat input is blocked while it is visible. It remembers the last active section on reopen (pending_settings_return).

Persistence

  • Changes write to CODE_HOME/config.toml when available; if that directory is missing you’ll see a warning and the changes remain session-only.
  • Access mode can be stored per workspace; other settings apply globally unless your config file overrides them per project.
  • Agent and MCP edits also live in the same config directory.

Sections

  • Model: pick the default chat model and reasoning effort.
  • Theme: choose a theme and spinner; applies immediately.
  • Updates: view upgrade channel/status. /update opens here before running installers.
  • Agents: see built-in/custom agents, enable/disable, force read-only, add per-agent instructions. Open the Subagent editor to configure /plan//solve//code or custom slash commands.
  • Prompts: edit saved prompt snippets.
  • Auto Drive: set review/agents/QA/cross-check toggles, continue mode (manual/immediate/ten-seconds/sixty-seconds), model override, or “use chat model.” Updates apply to active runs.
  • Review: choose a review model (or reuse chat), toggle auto-resolve, and set the max auto-resolve attempts.
  • Planning: pick model/effort for planning turns or reuse the chat model.
  • Validation: toggle validation groups and tools; see install status; trigger install help.
  • Limits: read-only view of rate limits and context/auto-compact usage.
  • Chrome: shown when browser attach fails; choose to retry, use a temp profile, switch to the internal browser, or cancel.
  • MCP: enable/disable MCP servers.
  • Notifications: toggle all or set filters. /notifications on|off|status also lands here.

Overlay lifecycle

  • All keys route through handle_settings_key while open; composer/history ignore input until closed.
  • Help overlay (?) closes before the main overlay when Esc is pressed.
  • Sections mark completion via their content structs; the overlay closes when a section reports is_complete (e.g., Chrome option chosen).

Scope reminders

  • Global defaults live in CODE_HOME/config.toml.
  • Workspace overrides are honored where setters accept cwd (access mode) or when project-level config files exist. The UI always renders merged effective values.
  • Agent commands and MCP servers are stored under CODE_HOME and apply to all workspaces unless overridden by project config.

Commands

  • /settings [section]
  • /auto settings
  • /update (or /update settings)
  • /notifications [on|off|status]
