You ask Claude Code to fix a failing validation function, then wait for a code block to copy into your editor. None arrives, but the session reports it is done. What most likely happened?

It was waiting for you to place your cursor where the fix should go
It edited the file directly, so the change is already on diskCorrect answer
It stopped early, because producing the code block is the final step
It only described the fix, because it cannot modify code without a plugin

Show answer & explanation

Correct answer: B. It edited the file directly, so the change is already on disk

Explanation

The principle — when the output is missing, check the file before you check the tool.

Why the key is correct — Anthropic's definition of agentic coding is a workflow where the AI reads files, runs commands and makes changes autonomously while you watch, redirect or step away, as opposed to chat-based assistants that only respond with text you must apply yourself. If the change has been applied, there is nothing left to paste. The habit that replaces copying is reading the diff, exactly as you would review a colleague's work.

Why the others are wrong — treating the code block as the final step imports the chat-assistant workflow. Needing a plugin to edit is not the case; the file-editing tools are part of the harness. And waiting for a cursor is autocomplete behaviour, which works from position rather than from a described task.

Remember this — no code block is usually success, not silence.
