Summary

• Fixed typo "on of" → "one of" in two error messages in ppadb_agent_os.py (lines 439, 450)
• Removed extra double space in the second error message
• Added empty-match guard in extract_click_coordinates() in anthropic/utils.py to raise a clear ValueError instead of IndexError when no coordinates are found in the LLM response

Changes

src/askui/tools/android/ppadb_agent_os.py

• Line 439: "did you call on of the set_device methods?" → "did you call one of the set_device methods?"
• Line 450: "did you call on of the set_display methods?" → "did you call one of the set_display methods?"

src/askui/models/anthropic/utils.py

• Added check: if re.findall() returns no matches, raise ValueError with descriptive message instead of crashing with IndexError on matches[-1]

Test plan

• Verified typo fixes are correct
• Verified the guard raises ValueError with a helpful message when no coordinates are found
• No behavioral change for the happy path — when coordinates exist, function works identically
