On mobile, a shell command in an expanded tool call showed as plain, proportional text. Web highlights it, colours scripts embedded in it (heredocs, python -c, node -e) in their own language, and uses a monospace font.

• Highlighting: the mobile work log draws the command through the native highlighter. It uses the same commandHighlightLanguage (shell or PowerShell) and withVisibleControlCharacters from client-runtime that web uses.
• Embedded scripts: embeddedScripts (the unbash parser) and the withEmbeddedScripts overlay moved from web into @t3tools/client-runtime/work-log/embedded-scripts, so both clients share them. Web still loads the module lazily. Mobile adds highlightCommand on top of its native tokenizer.
• Monospace on iOS: font-mono was configured only for Android. On iOS it got Tailwind's comma-separated font stack, which native text can't use, so it fell back to the system font. iOS now uses ui-monospace, the family the diff and file views already set directly. This fixes every font-mono use on iOS, not only this one. Highlighted token runs are plain RN Text so they inherit the font instead of resetting it to sans.

Approvability

Verdict: Approved at d9354dd

Macroscope's review found this PR approvable — Mobile tool commands gain monospace syntax highlighting using shared web rendering helpers. The changes affect presentation rather than command execution or stored data; the large-command performance suggestion does not demonstrate material impact.

Walkthrough

Thread command details now render through ToolCodeText. The displayed command is trimmed, control characters are made visible, and syntax highlighting is selected from the command content. ToolCodeText also accepts shellscript and powershell.

Changes: Thread Command Display

Layer / File(s)	Summary
Command rendering apps/mobile/src/features/threads/thread-work-log.tsx	Command details now use ToolCodeText with a command-selected highlighting language, visible control characters, and the current theme. ToolCodeText accepts shellscript and powershell.

Merge Risk: Low · up to 8d911

Mobile command rows now render with syntax highlighting. Very large commands could open slowly when expanded. The impact is limited to rare, oversized commands, so the change is mergeable, with a follow-up to bound the highlighting work.

Bound highlighting work for large commands.

An expanded command can contain an unrestricted number of lines. ToolCodeText highlights every line and creates text elements for its tokens, which can make large commands slow to open on mobile. Use plain text above a measured highlighting limit, while retaining the full command for selection and copy.
