Optional tools and providers

/tools, Settings → Tools and the command palette open one terminal-native browser. Discover searches the offline curated catalog by name, description or category. Within categories missing tools precede installed tools. Installed contains detected executables; Configure contains only real supported adapters; Errors contains retained installation failures or missing selected providers. No marketplace, update feed, network discovery or required external tool exists.

Up/Down selects, Left/Right changes tabs, typing searches, Enter opens details, Esc returns/clears/closes. Details show executable/version evidence, category, source and install package. I previews installation when missing, C opens a supported configuration adapter, P opens the existing provider chooser, and R explicitly refreshes detection. Toolchain detail labels consume offline Linguist through Chroma identity colors; status text remains separate.

Detection uses the existing cached provider resolver and bounded version probes, in batches of three on opening/refresh. Rendering never launches a probe or fetches network data. Installed means an executable is present, not that a daemon, credential, zsh hook or environment is healthy. Configured means an installed tool is selected in NMSh settings, not that its shell hooks are active. Hook inspection/setup is deferred and never inferred. Direct shell tools work normally.

Recommended tools: ripgrep, fd, fzf, jq, bat, zoxide and tealdeer. Enhanced tools are optional improvements; other entries (Fastfetch, frameworks, prompt engines, environment tools) stay curated and supported without a tier. Discover shows Recommended, Recommended + Enhanced (the default) or all curated tools (V). Installs are explicit: tools are selected (Space, or the R/E presets), reviewed with their exact commands, and confirmed once. Shell hooks are never modified. Legacy completed onboarding remains complete. The additive toolsSetupComplete boolean uses the existing normalizer/atomic NMSh preference writer.

Installation recipes are fixed Homebrew package argv, offered only when brew is available. Unsupported package managers get official-source guidance without execution; no sudo, shell interpolation, install scripts or custom taps. Each install shows the command and software-change scope, starts on No, and requires a fresh explicit confirmation. Shared TaskProgress reports actual completion and failures, with bounded captured diagnostics, detached process ownership and timeout/disposal cleanup. Installation never configures hooks/providers; after success availability is rechecked. No tools were installed during development.

The shared configuration panel implements Starship module toggles only, with supported-value previews, explicit apply, backup and atomic unknown-preserving writes. Native fallback works with all tools missing. Tool failures are retained only within the open browser; persistence across browser reopen, bulk selection, hook activation detection/setup and additional package managers remain deferred.

NO_COLOR retains text state cues, Safe glyph mode retains keyboard operation, and progress respects reduced motion. Extremely small widths necessarily clip descriptive/help rows; use a wider terminal to review installation/configuration. No mouse interaction is required.
