Task agent fails on Termux: EACCES permission denied for /tmp/claude

Description

Task agents fail on Termux (Android) because Claude Code tries to create directories under /tmp/claude/, which doesn't exist on Termux and cannot be created without root.

Error

EACCES: permission denied, mkdir '/tmp/claude/-data-data-com-termux-files-home-donna/tasks'

Environment

• Platform: Android (Termux)
• Claude Code version: Latest from npm

Expected Behavior

Claude Code should respect $TMPDIR environment variable or use a fallback temp directory that works on Termux.

Termux Context

Termux uses /data/data/com.termux/files/usr/tmp as its temp directory. The standard /tmp doesn't exist and requires root to create.

Suggested Fix

Use $TMPDIR if set, falling back to /tmp only if $TMPDIR is not defined.

const tmpBase = process.env.TMPDIR || '/tmp';

Workaround Attempted

Setting TMPDIR in .bashrc does not resolve the issue, suggesting the path is hardcoded.
