-Capability discovery defaults to `explicit`, preserving the zero-resident OpenPI tool surface until the user asks for a capability. The case-insensitive English words `subagent` and `workflow` are reserved authorization words: entering either word is sufficient to load its capability group, and the interactive editor shows it in Claude Code-style lavender before submission, with a darker purple fallback for light themes. This makes discussion that contains either English word an intentional opt-in tradeoff; conditional and negated clauses remain inert, while Chinese capability names still require a recognized action request. `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. Accepted Suggestion text is classified only after it becomes real editor input. The visual feedback and runtime activation share one fail-closed intent classifier. 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 plain layout (`cwd git pr |flex| model context`; `thinking`, `cache`, `cost`, and `throughput` remain opt-in metrics). 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 affects powerline separator glyphs (``) and adds Codex-style outline icons to compact read, terminal, edit, search, and directory activity rows; all accompanying text remains readable without it. Metrics carry small built-in Unicode icons (`📁` directory, `⎇` branch, `✦` model, and a `◔◑◕●` context gauge), all of which render in standard terminal fonts. 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). Ordinary `read`, `grep`, `find`, and `ls` operations render as one-line semantic activity summaries. Bash and Write/Edit default to the same activity-row projection, showing the target, running/success/failure state, and useful line or diff counts without replaying stdout or previews. Select full independently for Bash or Write/Edit to keep Pi's native rendering expanded. `app.tools.expand` temporarily restores the native arguments, output, errors, diff, timing, images, truncation notices, and full-output metadata; it never changes Session history or model context. 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`.

Nerd Font affects powerline separator glyphs (``) and adds Codex-style outline icons to compact read, terminal, edit, search, and directory activity rows; all accompanying text remains readable without it. Footer metrics use one Codicon outline family (`` model, `` context, and `` directory) plus `⎇` for the branch.
