What Claude Can Do During Calls

Read Files

"Claude, what's in the main.py file?" → Claude reads and explains the file

Search Code

"Can you find where we handle authentication?" → Claude searches and reports findings

Check Git Status

"What files have I changed today?" → Claude reports git diff summary

Review Code

"Review the changes I made to the API module" → Claude provides verbal code review

Brainstorm

"I need to add caching - what approaches should I consider?" → Claude discusses options with pros/cons

Example Conversation

[Phone rings]

Claude: "Hey Alex! I see you're working on the user-service
project. What would you like to discuss?"

You: "I'm having trouble with the authentication middleware.
Can you take a look at auth.py?"

Claude: "Sure, let me read that... I see you're using JWT
tokens. The issue might be on line 45 where you're checking
the expiry. You're comparing timestamps in different formats..."

You: "Oh, that makes sense. What's the fix?"

Claude: "You should convert both to Unix timestamps before
comparing. I'd suggest using datetime.timestamp() on line 45..."

Transcripts

Calls are automatically transcribed and saved:
