+| `ui.showToolCallArgs`                   | boolean          | Render tool calls on their own line with their full raw arguments inline, instead of the type-based compact summary that folds read/search/list batches into `Read 3 files`. Recovers parameters the per-tool description summarizes away (e.g. `Edit` normally shows only the filename). Useful when debugging MCP integrations or tool schemas. The args row is capped at 2 wrapped lines (and at most 1000 characters), so a batch of pending calls cannot outgrow the terminal; press `Ctrl+O` to lift the cap and expand result output too. Two cases keep the compact view: groups of running parallel subagents, which the live agent roster owns — expanding them re-inflates the live frame past the terminal height (#5798) — and daemon-attached sessions, which do not carry arguments across the daemon boundary. Use `Ctrl+O` there. TUI only — the web shell is unaffected.                                                                                                                                                                                                                                                                                                                                                                                                                | `false`       |
