 - 支持 `powerline`、`powerline-mono`、`compact`，也支持自定义多行布局；

-Capability discovery defaults to `explicit`, preserving the zero-resident OpenPI tool surface until the user asks for a capability. `adaptive` is an explicit opt-in that keeps only `openpi_load_tools` visible and allows the model to load a useful group on its own; because this can start Subagents, Workflows, or background processes, normal permission and configured concurrency/call limits still apply. Changing the setting updates the current Session immediately, while already loaded groups remain stable for that Session. Next-action suggestions default to off. Run `/openpi-setup` to explicitly choose an available model and reasoning level. After a fully settled main-agent run, one suggestion may appear as dim inline text on the first row of an empty editor; reserved cells at the row end keep CJK IME preedit from overwriting it. `Right` accepts it into the editor without submitting, while any other editor input dismisses it. Suggestions are ephemeral and never enter session history or model context. Workflows default to 8 concurrent agents and 128 total agent calls per run; configurable hard maxima are 64 and 1024. The large decorative header defaults off and the custom dashboard footer defaults on with a one-line Powerline layout (`cwd model thinking context cache cost throughput |flex| git pr`). Footer presets are `powerline`, `powerline-mono`, and `compact`; style can also be set independently to `plain`, `powerline`, or `powerline-mono`. Custom layouts use a 2D `footerLines` array with at most one `flex` per row for left/right alignment. Nerd Font only affects powerline separator glyphs (``); metric text stays readable without it. Footer changes apply immediately in the active TUI session. Subagent results default to the existing full display; compact mode shows only bounded status rows and keeps raw child reports behind `app.tools.expand` (`Ctrl+O` by default). Bash defaults to a folded one-line command with bounded output and a hidden-line count. Write/Edit defaults to an extra-short folded preview capped at three rendered lines including the operation header; its hidden-line hint remains inside the operation's status background. Select full independently for any category to keep it expanded. Compact views temporarily expand with `app.tools.expand`. An optional post-edit command is off by default: set one (for example `npm run format`, maximum 500 characters) and it runs once in the background after each interactive-TUI turn with successful Write/Edit operations, with failures reported as a notification. It deliberately does not guess whether arbitrary Bash commands changed files. Built-in Agent roles `explorer`, `implementer`, `reviewer`, and `advisor` are shared by `subagent_spawn.agent_type` and Workflow `agent(..., { agent_type })`; all inherit the parent model by default. `/openpi-setup` may assign a currently available Registry model to any subset; clearing one returns it to inheritance and omitted roles stay unchanged. Model precedence is explicit call > selected role-file model > setup assignment > parent inheritance; effort is explicit call > selected role > parent. A trusted project `.pi/agents/<role>.md` overrides global `~/.pi/agent/agents/<role>.md`, which overrides the complete built-in role definition; overrides are diagnosed. Role-model changes apply to the next spawn or Workflow agent call without reload. Configuration is stored privately at `~/.pi/agent/my-pi-setup.json`.
